KraneShares China Innovation ETF | Summary Prospectus

Investment Objective

The KraneShares China Innovation ETF (the "Fund") seeks growth of capital.

Fees and Expenses of the Fund

The following table describes the fees and expenses you may pay if you buy, hold, and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below.

____________

* Pursuant to a Distribution Plan, the Fund may bear a Rule 12b-1 fee not to exceed 0.25% per year of the Fund's average daily net assets. However, no such fee is currently paid by the Fund, and the Board of Trustees has not currently approved the commencement of any payments under the Distribution Plan.

** Based on estimated amounts for the current fiscal year. "Acquired Fund Fees and Expenses" are expenses incurred indirectly by the Fund through its ownership of shares of other investment companies (such as exchange-traded funds). They are not direct operating expenses paid by Fund shareholders and are not used to calculate the Fund's net asset value ("NAV"). In addition, "Acquired Fund Fees and Expenses" will not be reflected in the Fund's Financial Statements in its shareholder report. Therefore, the amounts listed in "Total Annual Fund Operating Expenses" and "Total Annual Fund Operating Expenses After Fee Waiver and Expense Reimbursement" will differ from those presented in the Fund's Financial Highlights.

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, whether you do or do not sell your shares, your costs would be:

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in the Annual Fund Operating Expenses or in the Example, affect the Fund's performance. Because the Fund has not commenced investment operations prior to the date of this prospectus, it does not have portfolio turnover information for the prior fiscal year to report.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by investing primarily in the Underlying ETFs shown below. Each Underlying ETF seeks, and each future Underlying ETF will seek, to provide investment results, before fees and expenses, corresponding to the price and yield performance of its respective underlying index and invests primarily in the publicly issued shares of companies that are based in, operate in or are otherwise economically tied to China, including A-Shares, B-Shares, H-Shares, P-Chips and Red Chips. The currently-projected allocation to each Underlying ETF is shown below:

• KWEB seeks to provide investment results that correspond to the CSI Overseas China Internet Index, which is designed to measure the performance of the investable universe of equities of publicly traded China-based companies that are listed outside of mainland China and whose primary business or businesses are in the Internet and Internet-related sectors.

• KURE seeks to provide investment results that correspond to the MSCI China All Shares Health Care 10/40 Index, which is designed to measure the performance of equity securities of Chinese companies in the healthcare sector.

• KGRN seeks to provide investment results that correspond to the MSCI China IMI Environment 10/40 Index, which is designed to measure the performance of equity securities of Chinese companies that focus on contributing to a more environmentally sustainable economy by making efficient use of scarce natural resources or by mitigating environmental degradation. Companies in the Underlying Index derive at least 50% of their revenues from products and services economically tied to: (1) alternative energy; (2) sustainable water; (3) green building; (4) pollution prevention; or (5) energy efficiency.

• KFVG seeks to provide investment results that correspond to the CICC China Technology Leaders Index, which includes the equity securities, or depositary receipts thereon, of the 30 largest Chinese companies by free-float market capitalization engaged in 5G and Technology-Related Industries - namely, Semiconductors, Electronic Equipment & Instruments, Electronic Manufacturing Services, Electronic Components, Communications Equipment, Internet Services & Infrastructure, Data Processing & Outsourced Services, IT Consulting & Other Services and Electrical Components & Equipment.

• KSTR seeks to provide investment results that correspond to the SSE Star Market 50 Component Index, which includes the equity securities or depositary receipts of the 50 largest companies by free-float market capitalization that are listed on the SSE STAR Market. The SSE STAR Market is a new listing exchange run by the Shanghai Stock Exchange that focuses on listing Chinese science and technology companies, including companies in high-tech and strategic emerging industries, such as next-generation information technology, biomedicine, and high-end equipment.

KraneShares China Innovation ETF | Summary Prospectus

Krane Funds Advisors, LLC ("Krane"), the Fund's investment adviser, will monitor market conditions and revise the allocations to the Underlying ETFs from time to time based on its assessment of market conditions, including the maturity of investment themes and the emergence of new themes.

In addition to investments in the Underlying ETFs, the Fund may invest up to 15% of its net assets in the securities of private companies, including those that may be preparing for an initial public offering. Krane generally expects to invest in private companies that are similar to (for example, in the same sector or industry as,) companies that are eligible for inclusion in an underlying index of an Underlying ETF. However, from time to time, the Fund may invest in other types of private companies, if Krane believes the investment represents an attractive opportunity for the Fund to invest in an issuer engaged in innovation in China or the surrounding region. An investment by the Fund in the securities of private companies will generally reduce the Fund's projected allocation to each Underlying ETF approximately pro rata.

Under normal circumstances, the Fund will invest at least 80% of its net assets (plus borrowings for investment purposes) in securities of issuers located in China, including other investments, such as investment companies, that provide investment exposure to such securities.

The Fund may engage in securities lending.

Principal Risks

As with all exchange traded funds ("ETFs"), a shareholder of the Fund is subject to the risk that his or her investment could lose money. The Fund may not achieve its investment objective and an investment in the Fund is not by itself a complete or balanced investment program. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. An investment in the Fund involves the risk of total loss. In addition to these risks, the Fund is subject to a number of additional principal risks (either directly or through its investments in the Underlying ETFs) that may affect the value of its shares, including:

China Risk. The Chinese economy is generally considered an emerging market and can be significantly affected by economic and political conditions in China and surrounding Asian countries. China may be subject to considerable degrees of economic, political and social instability. In addition, the Chinese economy is export-driven and highly reliant on trading with key partners. A downturn in the economies of China's primary trading partners could slow or eliminate the growth of the Chinese economy and adversely impact the Fund's investments. The Chinese government strictly regulates the payment of foreign currency denominated obligations and sets monetary policy. The Chinese government may introduce new laws and regulations that could have an adverse effect on the Fund. Although China has begun the process of privatizing certain sectors of its economy, privatized entities may lose money and/or be re-nationalized.

In the Chinese securities markets, a small number of issuers may represent a large portion of the entire market. The Chinese securities markets are subject to more frequent trading halts, low trading volume and price volatility. Recent developments in relations between the United States and China have heightened concerns of increased tariffs and restrictions on trade between the two countries. An increase in tariffs or trade restrictions, or even the threat of such developments, could lead to a significant reduction in international trade, which could have a negative impact on China's export industry and a commensurately negative impact on the Fund.

KraneShares China Innovation ETF | Summary Prospectus

In recent years, Chinese entities have incurred significant levels of debt and Chinese financial institutions currently hold relatively large amounts of non-performing debt. Thus, there exists a possibility that widespread defaults could occur, which could trigger a financial crisis, freeze Chinese debt and finance markets and make Chinese securities illiquid.

In addition, trade relations between the U.S. and China have recently been strained. Worsening trade relations between the two countries could adversely impact the Fund, particularly to the extent that the Chinese government restricts foreign investments in on-shore Chinese companies or the U.S. government restricts investments by U.S. investors in China. Worsening trade relations may also result in market volatility and volatility in the price of Fund shares.

Disclosure and regulatory standards in emerging market countries, such as China, are in many respects less stringent than U.S. standards. There is substantially less publicly available information about Chinese issuers than there is about U.S. issuers.

A-Shares Risk. A-Shares are issued by companies incorporated in mainland China and are traded on Chinese exchanges. Investments in A-Shares are made available to domestic Chinese investors and certain foreign investors, including those who have been approved as a QFII or a RQFII and through the Stock Connect Programs, which currently include the Shanghai-Hong Kong Stock Connect, Shenzhen-Hong Kong Stock Connect, Shanghai-London Stock Connect, and China-Japan Stock Connect. Investments by foreign investors in A-Shares are subject to various restrictions, regulations and limits. The Fund currently intends to gain exposure to A-Shares through the Stock Connect Programs. The Fund may also gain exposure to A-Shares by investing in investments that provide exposure to A-Shares, such as other investment companies, or Krane may acquire a QFII or RQFII license to invest in A-Shares for the Fund. Investments in A-Shares are heavily regulated and the recoupment and repatriation of assets invested in A-Shares is subject to restrictions by the Chinese government. A-Shares may be subject to frequent and widespread trading halts and may become illiquid. This could cause volatility in the Fund's share price and subject the Fund to a greater risk of trading halts.

Custody Risks. In accordance with Chinese regulations and the terms of a QFII or RQFII license, as applicable, and insofar as Krane acquires a QFII or RQFII license, A-Shares will be held in the joint names of the Fund and Krane. While Krane may not use such an account for any purpose other than for maintaining the Fund's assets, the Fund's assets may not be as well protected as they would be if it were possible for them to be registered and held solely in the name of the Fund. There is a risk that creditors of Krane may assert that the securities are owned by Krane and that regulatory actions taken against Krane may affect the Fund. The risk is particularly acute in the case of cash deposited with a People's Republic of China ("PRC") sub-custodian ("PRC Custodian") because it may not be segregated, and it may be treated as a debt owing from the PRC Custodian to the Fund as a depositor. Thus, in the event of a PRC Custodian bankruptcy, liquidation, or similar event, the Fund may face difficulties and/or encounter delays in recovering its cash.

Capital Controls Risk. Economic conditions, such as volatile currency exchange rates and interest rates, political events and other conditions may, without prior warning, lead to intervention by government actors and the imposition of "capital controls." Capital controls include the prohibition of, or restrictions on, the ability to transfer currency, securities or other assets. Levies may be placed on profits repatriated by foreign entities (such as the Fund). Although the RMB is not presently freely convertible, rather it is subject to the approval of the State Administration of Foreign Exchange ("SAFE") and other relevant authorities, repatriations by RQFIIs or through the Stock Connect

KraneShares China Innovation ETF | Summary Prospectus

Programs are currently permitted daily and Chinese authorities have indicated their plans to move to a fully freely convertible RMB. There is no assurance, however, that repatriation restrictions will not be (re-)imposed in the future.

Tax Risk. Per a circular (Caishui [2014] 79), the Fund is temporarily exempt from the Chinese tax on capital gains on trading in A-Shares as a QFII or RQFII or the Shanghai Stock Exchange through the Shanghai-Hong Kong Stock Connect as of November17, 2014, and the Shenzhen Stock Exchange through the Shenzhen-Hong Kong Stock Connect as of December5, 2016. There is no indication as to how long the temporary exemption will remain in effect. Accordingly, the Fund may be subject to such taxes in the future. In addition, there is uncertainty as to the application and implementation of China's value added tax to the Fund's activities. The Fund reserves the right to establish a reserve for taxes which present uncertainty as to whether they will be assessed, although it currently does not do so. If the Fund establishes such a reserve but is not ultimately subject to these taxes, shareholders who redeemed or sold their shares while the reserve was in place will effectively bear the tax and may not benefit from the later release, if any, of the reserve. Conversely, if the Fund does not establish such a reserve but ultimately is subject to the tax, shareholders who redeemed or sold their shares prior to the tax being withheld, reserved or paid will have effectively avoided the tax. Investors should note that such provision, if any, may be excessive or inadequate to meet actual tax liabilities (which could include interest and penalties) on the Fund's investments. Any taxes imposed in connection with the Fund's activities will be borne by the Fund. As a result, investors may be advantaged or disadvantaged depending on the final rules of the relevant tax authorities.

Hong Kong Risk. The economy of Hong Kong has few natural resources and any fluctuation or shortage in the commodity markets could have a significant adverse effect on the Hong Kong economy. Hong Kong is also heavily dependent on international trade and finance. Additionally, the continuation and success of the current political, economic, legal and social policies of Hong Kong is dependent on and subject to the control of the Chinese government. China may change its policies regarding Hong Kong at any time. Any such change may adversely affect market conditions and the performance of Chinese and Hong Kong issuers and, thus, the value of securities in the Fund's portfolio.

Stock Connect Program Risk. The Stock Connect Programs are subject to daily and aggregate quota limitations, and an investor cannot purchase and sell the same security on the same trading day, which may restrict the Fund's ability to invest in A-Shares through the Programs and to enter into or exit trades on a timely basis. The Shanghai and Shenzhen markets may be open at a time when the participating exchanges located outside of mainland China are not active, with the result that prices of A-Shares may fluctuate at times when the Fund is unable to add to or exit its positions. Only certain China A-Shares are eligible to be accessed through the Stock Connect Programs. Such securities may lose their eligibility at any time, in which case they could be sold but could no longer be purchased through the Stock Connect Programs. Because the Stock Connect Programs are still evolving, the actual effect on the market for trading A-Shares with the introduction of large numbers of foreign investors is still relatively unknown. Further, regulations or restrictions, such as limitations on redemptions or suspension of trading, may adversely impact the program. There is no guarantee that the participating exchanges will continue to support the Stock Connect Programs in the future.

Investments in China A-Shares may not be covered by the securities investor protection programs of either exchange and, without the protection of such programs, will be subject to the risk of default by the broker. Because of the way in which China A-Shares are held in the Stock Connect

KraneShares China Innovation ETF | Summary Prospectus

Programs, the Fund may not be able to exercise the rights of a shareholder and may be limited in its ability to pursue claims against the issuer of a security, and may suffer losses in the event the depository of the Chinese exchange becomes insolvent.

B-Shares Risk. The China B-Share market is generally smaller, less liquid and has a smaller issuer base than the China A-Share market. The issuers that compose the B-Share market include a broad range of companies, including companies with large, medium and small capitalizations. Further, the B-Shares market may behave very differently from other portions of the Chinese equity markets, and there may be little to no correlation between the performance of the two.

H-Shares Risk. H-Shares are foreign securities which, in addition to the risks described herein, are subject to the risk that the Hong Kong stock market may behave very differently from the mainland Chinese stock market. There may be little to no correlation between the performance of the Hong Kong stock market and the mainland Chinese stock market.

N-Shares Risk. N-Shares are securities of companies with business operations in mainland China and listed on an American stock exchange, such as the NYSE or NASDAQ. Because companies issuing N-Shares have business operations in China, they are subject to certain political and economic risks in China. The American stock market may behave very differently from the mainland Chinese stock market, and there may be little to no correlation between the performance of the two.

P-Chip Companies Risk. P-Chip companies are often run by the private sector and have a majority of their business operations in mainland China. P-Chip shares are traded in Hong Kong dollars on the Hong Kong Stock Exchange, and may also be traded by foreigners. Because they are traded on the Hong Kong Stock Exchange, P-Chips are also subject to risks similar to those associated with investments in H Shares. They are also subject to risks affecting their jurisdiction of incorporation, including any legal or tax changes.

Red Chip Companies Risk. Red Chip companies are controlled, either directly or indirectly, by the central, provincial or municipal governments of the PRC. Red Chip shares are traded in Hong Kong dollars on the Hong Kong Stock Exchange and may also be traded by foreigners. Because Red Chip companies are controlled by various PRC governmental authorities, investing in Red Chips involves risks that political changes, social instability, regulatory uncertainty, adverse diplomatic developments, asset expropriation or nationalization, or confiscatory taxation could adversely affect the performance of Red Chip companies. Red Chip companies may be less efficiently run and less profitable than other companies.

S-Chip Companies Risk. The Fund may invest in shares of companies with business operations in mainland China and listed on the Singapore Exchange ("S-Chips"). S-Chip shares are issued by companies incorporated anywhere, but many are registered in Singapore, the British Virgin Islands, the Cayman Islands, or Bermuda. They are subject to risks affecting their jurisdiction of incorporation, including any legal or tax changes. S-Chip companies may or may not be owned at least in part by a Chinese central, provincial or municipal government and be subject to the types of risks that come with such ownership described herein. There may be little or no correlation between the performance of the Singapore stock market and the mainland Chinese stock market.

As the Underlying ETFs, or the Fund's allocations among the Underlying ETFs, change from time to time, or to the extent that the total annual fund operating expenses of any Underlying ETF changes, the weighted average operating expenses borne by the Fund may increase or decrease.

KraneShares China Innovation ETF | Summary Prospectus

Internet Companies Risk. Investments in Internet companies may be volatile. Internet companies are subject to intense competition, the risk of product obsolescence, changes in consumer preferences and legal, regulatory and political changes. They are also especially at risk of hacking and other cybersecurity events. In addition, it can be difficult to determine what qualifies as an Internet company.

Environmental Issuers Risk. Issuers engaged in environmentally beneficial business lines may be difficult to identify and investments in them maybe volatile. They may be highly dependent upon government subsidies, contracts with government entities, and the successful development of new and proprietary technologies. Such technologies risk rapid product obsolescence, short product cycles, and competition from new market entrants. Current valuation methods used to value companies involved in alternative and clean power technology sectors have not been in widespread use for a significant period of time, and it is difficult to value share prices of such issuers. In addition, seasonal weather conditions, fluctuations in supply of and demand for clean energy products (including, in relation to traditional energy products, such as oil and gas), changes in energy prices, and international political events may cause fluctuations in the performance of these issuers and the prices of their securities. Other countries, including the U.S., may take steps against Chinese companies engaged in environmentally beneficial services and products, such as through the imposition of tariffs and anti-dumping duties. Even companies that are classified as being involved in environmentally beneficial services and products may not necessarily compare favorably with respect to their environmental practices and impact to those of other issuers.

Equity Securities Risk. The values of equity securities are subject to factors such as market fluctuations, changes in interest rates and perceived trends in stock prices. Equity securities may be more volatile than other asset classes and are generally subordinate in rank to debt and other securities of the same issuer.

Emerging Markets Risk. The Fund's investments in emerging markets are subject to greater risk of loss than investments in developed markets. This is due to, among other things, greater market volatility, greater risk of asset seizures and capital controls, lower trading volume, political and economic instability, greater risk of market shutdown, and more governmental limitations on foreign investments than typically found in developed markets. The economies of emerging markets, and China in particular, may be heavily reliant upon international trade and may suffer disproportionately if international trading declines or is disrupted.

Foreign Securities Risk. Investments in securities of non-U.S. issuers may be less liquid than investments in U.S. issuers, may have less governmental regulation and oversight, and are typically subject to different investor protection standards than U.S. issuers. Investments in non-U.S. securities entail the risk of loss due to foreign currency fluctuations and political or economic instability. Foreign market trading hours, clearance and settlement procedures, and holiday schedules may limit the Fund's ability to buy and sell securities. These factors could result in a loss to the Fund.

Geographic Focus Risk. The Fund's investments are expected to be focused in a particular country, countries, or region to the same extent as an Underlying ETF and therefore the Fund may be susceptible to adverse market, political, regulatory, and geographic events affecting that country, countries or region. Such geographic focus also may subject the Fund to a higher degree of volatility than a more geographically diversified fund.

KraneShares China Innovation ETF | Summary Prospectus

Pre-IPO Investments Risk. Investments in private companies that have not yet issued securities publicly in an initial public offering ("IPO") ("pre-IPO shares"), involve greater risks than investments in securities of companies that have traded publicly on an exchange for extended periods of time. Investments in these companies are generally less liquid than investments in securities issued by public companies and may be difficult for the Fund to value. Compared to public companies, private companies may have a more limited management group and limited operating histories with narrower, less established product lines and smaller market shares, which may cause them to be more vulnerable to competitors' actions, market conditions and consumer sentiment with respect to their products or services, as well as general economic downturns. In addition, private companies may have limited financial resources and may be unable to meet their obligations. The Fund may only have limited access to a private company's actual financial results and there is no assurance that the information obtained by the Fund is reliable. These companies may not ever issue shares in an IPO and a liquid market for their shares may never develop, which could adversely affect the Fund's liquidity. If the company does issue shares in an IPO, IPOs are risky and volatile and may cause the value of the Fund's investment to decrease significantly. Moreover, because securities issued by private companies are generally not freely or publicly tradable, the Fund may not have the opportunity to purchase, or the ability to sell, these securities in the amounts, or at the prices, the Fund desires.

Currency Risk. The Fund's net asset value ("NAV") is determined on the basis of the U.S. dollar, therefore, the Fund may lose value if the local currency of a foreign market depreciates against the U.S. dollar, even if the local currency value of the Fund's holdings goes up. Currency exchange rates can be very volatile and can change quickly and unpredictably, which may adversely affect the Fund. The Fund may also be subject to delays in converting or transferring U.S. dollars to foreign currencies for the purpose of purchasing portfolio investments. This may hinder the Fund's performance, including because any delay could result in the Fund missing an investment opportunity and purchasing securities at a higher price than originally intended, or incurring cash drag.

Non-Diversified Fund Risk. Because the Fund is non-diversified and may invest a greater portion of its assets in fewer issuers than a diversified fund, changes in the market value of a single portfolio holding could cause greater fluctuations in the Fund's share price than would occur in a diversified fund. This may increase the Fund's volatility and cause the performance of a single portfolio holding or a relatively small number of portfolio holdings to have a greater impact on the Fund's performance.

Concentration Risk. The Fund's assets are expected to be concentrated in an industry or group of industries to the extent that an Underlying ETF concentrates in a particular industry or group of industries. The securities of companies in an industry or group of industries could react similarly to market developments. Thus, the Fund is subject to loss due to adverse occurrences that affect one industry or group of industries or sector While the Fund's sector and industry exposure is expected to vary over time based on the composition of the Underlying ETFs, the Fund is currently subject to the principal risks described below.

Communication Services Sector Risk. The communication services sector may be dominated by a small number of companies which may lead to additional volatility in the sector. Communication services companies are particularly vulnerable to the potential obsolescence of products and services due to technological advances and the innovation of competitors. Communication services companies may also be affected by other competitive pressures, such as pricing competition, as well as research and development costs, substantial capital requirements, and government regulation. Fluctuating domestic and international demand, shifting demographics, and often unpredictable

KraneShares China Innovation ETF | Summary Prospectus

changes in consumer demand can drastically affect a communication services company's profitability. Compliance with governmental regulations, delays or failure to receive regulatory approvals, or the enactment of new regulatory requirements may negatively affect the business of telecommunication services companies. Certain companies in the communication services sector may be particular targets of network security breaches, hacking and potential theft of proprietary or consumer information, or disruptions in services, which would have a material adverse effect on their businesses.

Consumer Discretionary Sector Risk. The success of consumer product manufacturers and retailers is tied closely to the performance of the overall domestic and international economy, interest rates, competition and consumer confidence. Success depends heavily on disposable household income and consumer spending. Changes in demographics and consumer tastes can also affect the demand for, and success of, consumer products in the marketplace.

Information Technology Sector Risk. Market or economic factors impacting information technology companies and companies that rely heavily on technology advances could have a major effect on the value of stocks in the information technology sector. The value of stocks of technology companies and companies that rely heavily on technology is particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation and competition, both domestically and internationally, including competition from competitors with lower production costs. Information technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Information technology companies are heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely affect profitability. Additionally, companies in the information technology sector may face dramatic and often unpredictable changes in growth rates and competition for the services of qualified personnel.

Healthcare Sector Risk. The profitability of companies in the healthcare sector may be affected by government regulations and government healthcare programs, government reimbursement for medical expenses, increases or decreases in the cost of medical products and services, limited product lines, increased emphasis on the delivery of healthcare through outpatient services and product liability claims. Many healthcare companies are heavily dependent on patent protection, which may be time consuming and costly, and the expiration of a company's patent may adversely affect that company's profitability. Healthcare companies are subject to competitive forces that may result in pricing pressure, including price discounting, and may be thinly capitalized and susceptible to product obsolescence. Many new products in the healthcare sector require significant research and development and may be subject to regulatory approvals, which may be time consuming and costly and with no guarantee that the product will come to market.

Industrials Sector Risk. The industrials sector may be affected by changes in the supply and demand for products and services, product obsolescence, claims for environmental damage or product liability and general economic conditions, among other factors. Government regulation will also affect the performance of investments in such industrials sector issuers, particularly aerospace and defense companies, which rely to a significant extent on government demand for their products and services. Transportation companies, another component of the industrials sector, are subject to sharp price movements resulting from changes in the economy, fuel prices, labor agreements and insurance costs.

KraneShares China Innovation ETF | Summary Prospectus

Materials Sector Risk. The materials sector may be adversely impacted by the volatility of commodity prices, exchange rates, depletion of resources, over-production, litigation and government regulations, among other factors.

ETF Risk. As an ETF, the Fund is subject to the following risks:

Authorized Participants Concentration Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants. To the extent they exit the business or are otherwise unable to proceed in creation and redemption transactions with the Fund and no other Authorized Participant is able to step forward to create or redeem, shares of the Fund may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened for exchange-traded funds ("ETFs"), such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that have lower trading volumes.

Cash Transaction Risk. Like other ETFs, the Fund sells and redeems its shares only in large blocks called Creation Units and only to "Authorized Participants." Unlike many other ETFs, however, the Fund expects to effect its creations and redemptions at least partially or fully for cash, rather than in-kind securities. Thus, an investment in the Fund may be less tax-efficient than an investment in other ETFs as the Fund may recognize a capital gain that it could have avoided by making redemptions in-kind. As a result, the Fund may pay out higher capital gains distributions than ETFs that redeem in-kind. Further, paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio investments to obtain the cash needed to distribute redemption proceeds at an inopportune time.

International Closed Market Trading Risk. To the extent the Fund's investments trade in markets that are closed when the Fund and Exchange are open, there are likely to be deviations between current pricing of an underlying security and the prices at which the underlying securities are valued for purposes of the Fund's NAV. As a result, Shares may appear to trade at a significant discount or premium to NAV greater than those incurred by other ETFs. In addition, shareholders may not be able to purchase or redeem their shares of the Fund, or purchase or sell shares of the Fund on the Exchange, on days when the NAV of the Fund could be significantly affected by events in the relevant non-U.S. markets.

Premium/Discount Risk. There may be times when the market price of the Fund's shares is more than the NAV intra-day (at a premium) or less than the NAV intra-day (at a discount). As a result, shareholders of the Fund may pay more than NAV when purchasing shares and receive less than NAV when selling Fund shares. This risk is heightened in times of market volatility or periods of steep market declines. In such market conditions, market or stop-loss orders to sell Fund shares may be executed at prices well below NAV.

Secondary Market Trading Risk. Investors buying or selling shares in the secondary market will normally pay brokerage commissions, which are often a fixed amount and may be a significant proportional cost for investors buying or selling relatively small amounts of shares. Secondary market trading is subject to bid-ask spreads and trading in Fund shares may be halted by the Exchange because of market conditions or other reasons. If a trading halt occurs, a shareholder may temporarily be unable to purchase or sell shares of the Fund. In addition, although the Fund's shares are listed on the Exchange, there can be no assurance that an active trading market for shares will develop or be maintained or that the Fund's shares will continue to be listed.

KraneShares China Innovation ETF | Summary Prospectus

New Fund Risk. If the Fund does not grow in size, it will be at greater risk than larger funds of wider bid-ask spreads for its shares, trading at a greater premium or discount to NAV, liquidation and/or a stop to trading.

Liquidity Risk. The Fund's investments are subject to liquidity risk, which exists when an investment is or becomes difficult or impossible to purchase or sell at an advantageous time and price. If a transaction is particularly large or if the relevant market is or becomes illiquid, it may not be possible to initiate a transaction or liquidate a position, which may cause the Fund to suffer significant losses and difficulties in meeting redemptions. Liquidity risk may be the result of, among other things, market turmoil, the reduced number and capacity of traditional market participants, or the lack of an active trading market. Markets for securities or financial instruments could be disrupted by a number of events, including, but not limited to, an economic crisis, natural disasters, new legislation or regulatory changes inside or outside the U.S. Liquid investments may become less liquid after being purchased by the Fund, particularly during periods of market stress. In addition, if a number of securities held by the Fund stop trading, it may have a cascading effect and cause the Fund to halt trading. Volatility in market prices will increase the risk of the Fund being subject to a trading halt. Certain countries in which the Fund may invest may be subject to extended settlement delays and/or foreign holidays, during which the Fund will unlikely be able to convert holdings to cash.

Small- and Mid-Capitalization Company Risk. Investing in the securities of small and medium capitalization companies involves greater risk and the possibility of greater price volatility than investing in larger capitalization companies. Since small and medium-sized companies may have limited operating histories, product lines and financial resources, the securities of these companies may be less liquid and more volatile. They may also be sensitive to (expected) changes in interest rates and earnings.

Large Capitalization Company Risk. Large capitalization companies may be unable to respond quickly to new competitive challenges and attain the high growth rate of successful smaller companies, especially during extended periods of economic expansion. As such, returns on investments in stocks of large capitalization companies could trail the returns on investments in stocks of small and mid-capitalization companies.

Passive Investment Risk. There is no guarantee that the Underlying ETFs will create the desired exposure and the Underlying ETFs are not actively managed. An Underlying ETF does not seek to "beat" its underlying index or take temporary defensive positions when markets decline. Therefore, an Underlying ETF may purchase or hold securities with current or projected underperformance.

Management Risk. The Fund is actively-managed and may not meet its investment objective based on the Adviser's success or failure to implement investment strategies for the Fund. The Adviser's evaluations and assumptions regarding investments, interest rates, inflation, and other factors may not successfully achieve the Fund's investment objective given actual market conditions.

Tracking Error Risk. An Underlying ETF's return may not match or achieve a high degree of correlation with the return of its respective underlying indexes. This may be due to, among other factors, the Underlying ETFs holding cash under certain circumstances in lieu of securities of its underlying index, such as when the Underlying ETF is subject to delays converting U.S. dollars into a foreign currency to purchase foreign securities and unable to invest in certain components of the Underlying ETFs due to regulatory constraints, trading suspensions, and legal restrictions imposed by foreign governments. To the extent that an Underlying ETF employs a representative sampling strategy or calculates its NAV

KraneShares China Innovation ETF | Summary Prospectus

based on fair value prices and the value of an Underlying ETF is based on securities' closing prices on local foreign markets, an Underlying ETF's ability to track the underlying index may be adversely affected.

Market Risk. The values of the Fund's holdings could decline generally or could underperform other investments. In addition, there is a risk that policy changes by the U.S. Government, Federal Reserve, and/or other government actors could cause volatility in global financial markets and negative sentiment, which could have a negative impact on the Fund and could result in losses. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. Further, the Fund is susceptible to the risk that certain investments may be difficult or impossible to sell at a favorable time or price. Market developments may also cause the Fund's investments to become less liquid and subject to erratic price movements. Such market developments may also cause the Fund to encounter difficulties in timely honoring redemptions.

High Portfolio Turnover Risk. The Fund may incur high portfolio turnover rates, which may increase the Fund's brokerage commission costs and negatively impact the Fund's performance. Such portfolio turnover also may generate net short-term capital gains.

Valuation Risk. Independent market quotations for certain investments held by the Fund may not be readily available, and such investments may be fair valued or valued by a pricing service at an evaluated price. These valuations involve subjectivity and different market participants may assign different prices to the same investment. As a result, there is a risk that the Fund may not be able to sell an investment at the price assigned to the investment by the Fund. In addition, the securities in which the Fund invests may trade on days that the Fund does not price its shares; as a result, the value of Fund shares may change on days when investors cannot purchase or sell their Fund holdings.

Tax Risk. In order to qualify for the favorable tax treatment available to regulated investment companies, the Fund must satisfy certain income, asset diversification and distribution requirements each year. The Fund's investments in issuers whose control persons are not certain creates a risk that tax authorities may retrospectively deem the Fund to have failed the asset diversification requirements. If the Fund were to fail the favorable tax treatment requirements, it would be taxed in the same manner as an ordinary corporation, which would adversely affect its performance.

Depositary Receipts Risk. The Fund may hold the securities of foreign companies in the form of depositary receipts, including American Depositary Receipts and Global Depositary Receipts. Investing in depositary receipts entails the risks associated with foreign investments, such as fluctuations in foreign currency exchange rates and political and economic risks distinct from those associated with investing in the securities of U.S. issuers. In addition, the value of the securities underlying the depositary receipts may change materially when the U.S. markets are not open for trading, which will affect the value of the depositary receipts.

Derivatives Risk. The use of derivatives (including swaps, futures, forwards, structured notes and options) may involve leverage, which includes risks that are different from, and greater than, the risks associated with investing directly in a reference asset, because a small investment in a derivative can result in a large impact on the Fund and may cause the Fund to be more volatile. Derivatives may at times be highly illiquid, and the Fund may not be able to close out or sell a derivative at a particular time or at an anticipated price. Derivatives can be difficult to value and valuation may be

more difficult in times of market turmoil. There may be imperfect correlation between the derivative and that of the reference asset, resulting in unexpected returns that could materially adversely affect the Fund. Certain derivatives (such as swaps and options) are bi-lateral agreements that expose the Fund to counterparty risk, which is the risk of loss in the event that the counterparty to an agreement fails to make required payments or otherwise comply with the terms of derivative. In that case, the Fund may suffer losses potentially equal to, or greater than, the full value of the derivative if the counterparty fails to perform its obligations. That risk is generally thought to be greater with over-the-counter (OTC) derivatives than with derivatives that are exchange traded or centrally cleared. Counterparty risks are compounded by the fact that there are only a limited number of ways available to invest in certain reference assets and, therefore, there may be few counterparties to swaps or options based on those reference assets. Many derivatives are subject to segregation requirements that require the Fund to segregate the market or notional value of the derivatives, which could impede the portfolio management of the Fund.

Investments in Investment Companies Risk. The Fund will invest in other investment companies, including those that are advised, sponsored or otherwise serviced by Krane and/or its affiliates, which include the Underlying ETFs. The Fund will indirectly be exposed to the risks of investments by such funds and will incur its pro rata share of the underlying fund's expenses. Additionally, investments in ETFs are subject to ETF Risk. Krane is subject to conflicts of interest in allocating Fund assets to investment companies that are advised, sponsored or otherwise serviced by Krane and/or its affiliates. To the extent that the Fund invests in investment companies or other pooled investment vehicles that are not registered pursuant to the 1940 Act, including foreign investment companies, it will not enjoy the protections of the U.S. law.

Securities Lending Risk. To the extent the Fund lends its securities, it may be subject to the following risks: (1) the securities in which the collateral is invested may not perform sufficiently to cover the applicable rebate rates paid to borrowers and related administrative costs; (2) delays may occur in the recovery of securities from borrowers, which could interfere with the Fund's ability to vote proxies or to settle transactions; and (3) although borrowers of the Fund's securities typically provide collateral in the form of cash that is reinvested in securities, there is the risk of possible loss of rights in the collateral should the borrower fail financially.

Cash and Cash Equivalents Risk. The Fund may hold cash or cash equivalents. Generally, such positions offer less potential for gain than other investments. Holding cash or cash equivalents, even strategically, may lead to missed investment opportunities. This is particularly true when the market for other investments in which the Fund may invest is rapidly rising. If the Fund holds cash uninvested it will be subject to the credit risk of the depositing institution holding the cash.

Performance Information

Once the Fund has completed a full calendar year of operations, a bar chart and table will be included in this Prospectus that will provide some indication of the risks of investing in the Fund by showing the variability of the Fund's return based on net assets and comparing the variability of the Fund's return to a broad measure of market performance. Once available, the Fund's current performance information will be available at www.kraneshares.com. Past performance does not necessarily indicate how the Fund will perform in the future.

Management

Investment Adviser

Krane Funds Advisors, LLC ("Krane" or "Adviser") serves as the investment adviser to the Fund.

Portfolio Managers

James Maund, Head of Capital Markets at the Adviser, has served as a portfolio manager of the Fund since its inception. Jonathan Shelon, Chief Operating Officer of the Adviser, supports Mr.Maund and has been a portfolio manager of the Fund since its inception. Anthony Sassine, Senior Investment Strategist of the Adviser, has been a portfolio manager of the Fund since its inception.

Purchase and Sale of Fund Shares

Shares may be purchased and redeemed from the Fund only in "Creation Units" of 50,000shares, or multiples thereof. As a practical matter, only institutions and large investors, such as market makers or other large broker-dealers, purchase or redeem Creation Units. Most investors will buy and sell shares of the Fund on the Exchange. Individual shares can be bought and sold throughout the trading day like other publicly traded securities through a broker-dealer on the Exchange. These transactions do not involve the Fund. The price of an individual Fund share is based on market prices, which may be different from its NAV. As a result, the Fund's shares may trade at a price greater than the NAV (at a premium) or less than the NAV (at a discount). An investor may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase shares of the Fund (bid) and the lowest price a seller is willing to accept for shares of the Fund (ask) when buying or selling shares in the secondary market (the "bid-ask spread"). Most investors will incur customary brokerage commissions and charges when buying or selling shares of the Fund through a broker-dealer.

Because the Fund has not commenced operations as the Fund's most recently completed fiscal year, the Fund did not have a sufficient trading history to report trading information and related costs. Once the Fund commences operations, recent information regarding the Fund, including its NAV, market price, premiums and discounts, and bid ask spreads, will be available on the Fund's website at www.kraneshares.com.

Tax Information

Fund distributions are generally taxable as ordinary income, qualified dividend income or capital gains (or a combination), unless your investment is in an IRA or other tax-advantaged retirement account, which may be taxable upon withdrawal.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase Fund shares through a broker-dealer or other financial intermediary (such as a bank), the Fund and its related companies may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your sales person to recommend the Fund over another investment. Ask your sales person or visit your financial intermediary's website for more information.
