Investment Objective
ProShares Ultra Bitcoin ETF (the “Fund”) seeks daily investment results, before fees and expenses, that correspond to two times (2x) the daily performance of the Bloomberg Bitcoin Index (the “Index”).
In this manner, the Fund seeks daily returns that correspond to two times (2x) the price of bitcoin. The Fund does not invest directly in bitcoin.
Important Information About the Fund
If the Fund is successful in meeting its investment objective, it should gain approximately two times as much as the Index when the Index rises on a given day. Conversely, it should lose approximately two times as much as the Index when the Index falls on a given day. The Fund does not seek to achieve two times (2x) the daily performance of the Index (the “Daily Target”) for any period other than a day.
While the Fund has a daily investment objective, you may hold Fund shares for longer than one day if you believe doing so is consistent with your goals and risk tolerance. If you hold fund shares for any period other than a day, it is important for you to understand that over your holding period:
•Your return may be higher or lower than the Daily Target, and this difference may be significant.
•Factors that contribute to returns that are worse than the Daily Target include smaller Index gains or losses and higher Index volatility, as well as longer holding periods when these factors apply.
•Factors that contribute to returns that are better than the Daily Target include larger Index gains or losses and lower Index volatility, as well as longer holding periods when these factors apply.
•The more extreme these factors are, and the more they occur together, the more your return will tend to deviate from the Daily Target.
Fees and Expenses of the Fund
The table below describes the fees and expenses that 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.

“Other Expenses” are estimated.
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 and then redeem or hold all of your shares at the end of each period. 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 your approximate costs would be:

The Fund pays transaction and financing costs associated with the purchase and sale of securities and derivatives. These costs are not reflected in the table or the example above.
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 the Fund’s shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the example above, affect the Fund’s performance. Because the Fund is newly organized, portfolio turnover information is not yet available.
Principal Investment Strategies
The Fund invests in financial instruments that ProShare Advisors believes, in combination, should produce daily returns consistent with the Daily Target. In this manner, the Fund seeks daily returns that correspond to two times (2x) the price of bitcoin. The Fund does not invest directly in bitcoin.
Bitcoin is a digital asset. The ownership and operation of bitcoin is determined by participants in an online, peer-to-peer network sometimes referred to as the “Bitcoin Network”. The Bitcoin Network connects computers that run publicly accessible, or “open source,” software that follows the rules and procedures governing the Bitcoin Network. This is commonly referred to as the Bitcoin Protocol (and is described in more detail in the section entitled “The Bitcoin Protocol” in the Fund’s Prospectus). Bitcoin may be used to pay for goods and services, stored for future use, or converted to a government-issued currency. As of the date of this Prospectus, the adoption of bitcoin for these purposes has been limited and bitcoin presently is not widely accepted as a means of payment.
The value of bitcoin is not backed by any government, corporation, or other identified body. Instead, its value is determined in part by the supply and demand in markets created to facilitate trading of bitcoin. Ownership and transaction records for bitcoin are protected through public-key cryptography. The supply of bitcoin is determined by the Bitcoin Protocol. No single entity owns or operates the Bitcoin Network. The Bitcoin Network is collectively maintained by (1) a decentralized group of participants who run computer software

PROSHARES.COM
that results in the recording and validation of transactions (commonly referred to as “miners”), (2) developers who propose improvements to the Bitcoin Protocol and the software that enforces the protocol and (3) users who choose which version of the bitcoin software to run. From time to time, the developers suggest changes to the bitcoin software. If a sufficient number of users and miners elect not to adopt the changes, a new digital asset, operating on the earlier version of the bitcoin software, may be created. This is often referred to as a “fork.” The value of the Fund may reflect the impact of these forks.
The Index is designed to measure the performance of a single bitcoin traded in USD and seeks to provide a proxy for the bitcoin market. The Index price is a composite of U.S. dollar-bitcoin trading activities reported by certain digital asset trading platforms that are evaluated based on a variety of different criteria, including the trading platforms’ oversight and governance controls, liquidity, capital controls, data transparency and data integrity. The digital asset trading platforms included in the Index are reevaluated quarterly. The Index is constructed and maintained by Bloomberg Index Services Limited. More information about the Index is published under the Bloomberg ticker symbol “BITCOIN”.
Under normal circumstances, the Fund will invest at least 80% of the Fund’s assets in, or provide exposure to, financial instruments that ProShare Advisors believes, in combination, should produce daily returns consistent with the Daily Target.
The Fund will invest principally in the financial instruments listed below.
•Swap Agreements – The Fund may enter into swap agreements that provide exposure to bitcoin. Swap agreements are derivative contracts entered into primarily with major global financial institutions for a specified period ranging from a day to more than one year. In a standard swap transaction, two parties agree to exchange or “swap” payments based on the change in value of an underlying asset or benchmark. For example, two parties may agree to exchange the return (or differentials in rates of returns) earned or realized on a particular investment or instrument.
•Money Market Instruments — The Fund expects that any cash balances maintained in connection with its use of derivatives will typically be held in high quality, short-term money market instruments, for example:
○U.S. Treasury Bills — U.S. government securities that have initial maturities of one year or less, and are supported by the full faith and credit of the U.S. government.
○Repurchase Agreements — Contracts in which a seller of securities, usually U.S. government securities or other money market instruments, agrees to buy the securities back at a specified time and price.
ProShare Advisors uses a mathematical approach to investing in which it determines the type, quantity and mix of investment positions that it believes, in combination, the Fund
should hold to produce daily returns consistent with the Daily Target. For these purposes a day is measured from the time of one net asset value (“NAV”) calculation to the next.
The Fund seeks to remain fully invested at all times in financial instruments that, in combination, provide leveraged exposure consistent with the investment objective, without regard to market conditions, trends or direction.
The Fund seeks to rebalance its portfolio each day so that its exposure to the Index is consistent with the Daily Target. The Index’s movements during the day will affect whether the Fund’s portfolio needs to be rebalanced. For example, if the Index has risen on a given day, net assets of the Fund should rise (assuming there were no Creation Unit redemptions). As a result, the Fund’s exposure will need to be increased. Conversely, if the Index has fallen on a given day, net assets of the Fund should fall (assuming there were no Creation Units issued). As a result, the Fund’s exposure will need to be decreased.
Please see “Investment Objectives, Principal Investment Strategies and Related Risks” in the Fund’s Prospectus for additional details.
Principal Risks
You could lose money by investing in the Fund.
•Investment Strategy Risk – The Fund obtains leveraged exposure to bitcoin in a manner designed to provide leveraged exposure to the single day returns of the Index. The Fund does not directly buy bitcoin. Investors seeking exposure to bitcoin directly should consider an investment other than the Fund.
•Leverage Risk — The Fund uses leverage and will lose more money when the value of the Index falls than a similar fund that does not use leverage. The use of leverage increases the risk of a total loss of your investment. If the Index approaches a 50% loss at any point in the day, you could lose your entire investment. As a result, an investment in the Fund may not be suitable for all investors. The use of leverage increases the volatility of your returns. The cost of obtaining this leverage will lower your returns.
•Holding Period Risk — The performance of the Fund for periods longer than a single day will likely differ from the Daily Target. This difference may be significant. If you are considering holding fund shares for longer than a day, it’s important that you understand the impact of Index returns and Index volatility (how much the value of the Index moves up and down from day-to-day) on your holding period return. Index volatility has a negative impact on Fund returns. During periods of higher Index volatility, the Index volatility may affect the Fund’s returns as much as or more than the return of the Index.
The following table illustrates the impact of Index volatility and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. The longer
   ProShares Ultra Bitcoin ETF :: 5
PROSHARES.COM
you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.
In the table areas shaded darker represent those scenarios where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility. You may lose money when the Index return is flat (i.e., close to zero) and you may lose money when the Index rises.
The table uses hypothetical annualized Index volatility and Index returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Index return for a one-year period. Each column corresponds to a level of hypothetical annualized Index volatility. For example, the Fund may mistakenly be expected to achieve a -40% return on a yearly basis if the annual Index return were -20%. However, as the table shows, with a one-year Index return of -20% and an annualized Index volatility of 50%, the Fund could be expected to return -50.2%.

Assumes: (a) no Fund expenses and (b) borrowing/lending rates (to obtain leveraged exposure) of zero percent. If these were included the Fund’s performance would be different from that shown.
The Index’s annualized historical volatility rate for the five-year period ended May 31, 2023 was 68.75%. The Index’s highest May to May volatility rate during the five-year period was 79.54% (May 29, 2020). The Index’s annualized total return performance for the five-year period ended May 31, 2023 was 25.45%. Historical Index volatility and
performance do not predict future Index volatility and performance.

•Correlation Risk — A number of factors may affect the Fund’s ability to achieve a high degree of leveraged correlation with the Index. Fees, expenses, transaction costs, financing costs associated with the use of derivatives, among other factors, will adversely impact the Fund’s ability to meet its Daily Target. In addition, if for any reason the Fund is unable to rebalance all or a portion of its investments, the Fund may have exposure to the Index that is significantly greater or less than the Daily Target. Any of these factors may prevent the Fund from achieving exposure consistent with the Daily Target.
•Risks Associated with the Use of Derivatives — Investing in derivatives to obtain leveraged exposure may be considered aggressive and may expose the Fund to greater risks including counterparty risk and correlation risk. The Fund may lose money if its derivatives do not perform as expected and may even lose money if they do perform as expected. To the extent the Fund invests in swaps that use an ETF as the reference asset, the Fund will be subject to the risks of that ETF including the risk that the ETF may not meet its investment objective. In addition, the Fund may be subject to greater correlation risk since the performance of the ETF may not correlate to the performance of the Index. Any costs associated with using derivatives will reduce the Fund’s return.
•Counterparty Risk — The Fund may lose money if a counterparty does not meet its contractual obligations.
Counterparties may impose margin requirements, exposure limits, and collateral requirements that may limit the Fund’s ability to achieve its desired leveraged exposure to bitcoin. In addition, the Fund has a limited number of counterparties, which may limit the ability of the Fund to obtain leveraged exposure to bitcoin. Moreover, the Fund generally structures its agreements so that the Fund or the counterparty can terminate the contract at any time without penalty. This means there is a risk that the Fund’s counterparties may terminate the Fund’s swap agreements and no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund that provide sufficient leveraged exposure to bitcoin. As an example, if the Index has a dramatic intraday move, the terms of a swap agreement between the Fund and its counterparty may permit the counterparty to immediately close out the transaction with the Fund. In that event, the Fund may be unable to enter into another swap agreement or invest in other derivatives to achieve its Daily Target. If

the Fund cannot obtain sufficient leveraged exposure to bitcoin, the Fund will not meet its Daily Target.
•Bitcoin Market Volatility Risk – The prices of bitcoin have historically been highly volatile. The value of the Fund’s leveraged exposure bitcoin – and therefore the value of an investment in the Fund – could decline significantly and without warning, including to zero. If you are not prepared to accept significant and unexpected changes in the value of the Fund and the possibility that you could lose your entire investment in the Fund you should not invest in the Fund.
Trading prices of bitcoin and other digital assets have experienced significant volatility in recent periods and may continue to do so. For instance, there were steep increases in the value of certain digital assets, including bitcoin over the course of 2021, and multiple market observers asserted that digital assets were experiencing a “bubble.” These increases were followed by steep drawdowns throughout 2022 in digital asset trading prices, including for bitcoin. These episodes of rapid price appreciation followed by steep drawdowns have occurred multiple times throughout bitcoin’s history, including in 2011, 2013-2014, and 2017-2018, before repeating again in 2021-2022. In 2023 and over the course of 2024, bitcoin prices have continued to exhibit extreme volatility. Such volatility is expected to persist.
•Bitcoin Risk – Bitcoin is a relatively new innovation and is subject to unique and substantial risks. The market for bitcoin is subject to rapid price swings, changes and uncertainty.
The further development of the Bitcoin Network and the acceptance and use of bitcoin are subject to a variety of factors that are difficult to evaluate. The slowing, stopping or reversing of the development of the Bitcoin Network or the acceptance of bitcoin may adversely affect the price and liquidity of bitcoin. The widespread adoption of a competing digital asset or blockchain may result in a reduction in demand for bitcoin. A significant portion of the demand for bitcoin may be the result of speculation. Such speculation regarding the potential future appreciation in the price of bitcoin may artificially inflate or deflate the price of bitcoin and increase volatility. Bitcoin is subject to the risk of fraud, theft, manipulation or security failures, operational or other problems that impact digital asset trading venues. Additionally, if one or a coordinated group of miners were to gain control of 51% of the Bitcoin Network, they would have the ability to execute extensive attacks, manipulate transactions, halt payments and fraudulently obtain bitcoin. A significant portion of bitcoin is held by a small number of holders sometimes referred to as “whales”.
Transactions by these holders may influence the price of bitcoin.
Unlike the exchanges for more traditional assets, such as equity securities and futures contracts, bitcoin and digital asset trading venues are largely unregulated, may be operating out of compliance with regulation, and are highly fragmented. As a result of the lack of regulation, individuals or groups may engage in fraud or market manipulation (including using social media to promote bitcoin in a way that artificially increases the price of bitcoin). Investors may be more exposed to the risk of theft, fraud and market manipulation than when investing in more traditional asset classes. Over the past several years, a number of digital asset trading venues have been closed due to fraud, failure or security breaches. Investors in bitcoin may have little or no recourse should such theft, fraud or manipulation occur and could suffer significant losses. Legal or regulatory changes may negatively impact the operation of the Bitcoin Network or restrict the use of bitcoin. In addition, digital asset trading venues, bitcoin miners, and other participants may have significant exposure to other digital assets. Instability in the price, availability or legal or regulatory status of those instruments may adversely impact the operation of the digital asset trading venues and the Bitcoin Network. As a result, events that are not necessarily related to the security or utility of bitcoin can nonetheless cause a significant decline in the price of bitcoin (e.g., the collapse of TerraUSD in May 2022 and FTX Trading Ltd. in November 2022).
The realization of any of these risks could result in a decline in the acceptance of bitcoin and consequently a reduction in the value of bitcoin and the Fund. Finally, the creation of a “fork” (as described above) or a substantial giveaway of bitcoin (sometimes referred to as an “air drop”) may result in significant and unexpected declines in the value of bitcoin and the Fund.
•Money Market Instruments Risk — Adverse economic, political or market events affecting issuers of money market instruments, defaults by counterparties or changes in government regulations may have a negative impact on the performance of the Fund.
•Non-Diversification Risk — The Fund has the ability to invest a relatively high percentage of its assets in the securities of a small number of issuers or in financial instruments with a single counterparty or a few counterparties. This may increase the Fund’s volatility and increase the risk that the Fund’s performance will decline based on the performance of a single issuer or the credit of a single counterparty.
   ProShares Ultra Bitcoin ETF :: 7
PROSHARES.COM
•Concentration Risk — The Fund has a significant exposure to bitcoin. As a result, the Fund may be subject to greater market fluctuations than a fund that is more broadly invested across industries.
•Index Performance Risk — The Index used by the Fund may underperform other asset classes and may underperform other similar indices. The Index is maintained by a third party provider unaffiliated with the Fund or ProShare Advisors. There can be no guarantee that the methodology underlying the Index or the daily calculation of the Index will be free from error.
•Intraday Price Performance Risk — The intraday performance of Fund shares traded in the secondary market generally will be different from the performance of the Fund when measured from one NAV calculation-time to the next. When shares are bought intraday, the performance of the Fund’s shares relative to the Index until the Fund’s next NAV calculation time will generally be higher or lower than the Daily Target.
•Market Price Variance Risk — Investors buy and sell Fund shares in the secondary market at market prices. Market prices may be different from the NAV per share of the Fund (i.e., the secondary market price may trade at a price greater than NAV (a premium) or less than NAV (a discount)). The market price of the Fund’s shares will fluctuate in response to changes in the value of the Fund’s holdings, supply and demand for shares and other market factors. In addition, bitcoin may be traded in markets on days and at times when the Fund’s listing exchange is closed for trading. As a result, the value of the Fund’s holdings may vary, perhaps significantly, on days and at times when investors are unable to purchase or sell Fund shares. ProShare Advisors cannot predict whether shares will trade above, below or at a price equal to the value of the Fund’s holdings factors.
•Authorized Participant Risk — The Fund has a limited number of financial institutions that act as Authorized Participants or market markers. Only Authorized Participants may engage in creation or redemption transactions directly with the Fund. If some or all of these Authorized Participants exit the business or are unable to process creation and/or redemption orders, and other Authorized Participants are not willing or able to create and redeem Fund shares, investors may experience a significantly diminished trading market and the shares may trade at a discount to NAV.
•New Fund Risk — The Fund recently commenced operations, has a limited operating history, and started operations with a small asset base. There can be no assurance that the Fund
will be successful or grow to or maintain a viable size, that an active trading market for the Fund’s shares will develop or be maintained, or that the Fund’s shares’ listing will continue unchanged.
Please see “Investment Objectives, Principal Investment Strategies and Related Risks” in the Fund’s Prospectus for additional details.
Investment Results
Performance history will be available for the Fund after it has been in operation for a full calendar year. After the Fund has a full calendar year of performance information, performance information will be shown on an annual basis.
Management
The Fund is advised by ProShare Advisors. Alexander Ilyasov, Senior Portfolio Manager, and George Banian, Portfolio Manager, have jointly and primarily managed the Fund since inception.
Purchase and Sale of Fund Shares
The Fund will issue and redeem shares only to Authorized Participants (typically broker-dealers) in exchange for cash in large blocks, known as Creation Units. Shares of the Fund may only be purchased and sold by retail investors in secondary market transactions through broker-dealers or other financial intermediaries. Shares of the Fund are listed for trading on a national securities exchange and because shares trade at market prices rather than NAV, shares of the Fund may trade at a price greater than NAV (premium) or less than NAV (discount). In addition to brokerage commissions, investors incur the costs of the difference between the highest price a buyer is willing to pay to purchase shares of the Funds (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”). The bid-ask spread varies over time for Fund shares based on trading volume and market liquidity. Recent information, including information about a Fund’s NAV, market price, premiums and discounts, and bid-ask spreads, is included on the Fund’s website (www.proshares.com).
Tax Information
Income and capital gains distributions you receive from the Fund generally are subject to federal income taxes and may also be subject to state and local taxes. The Fund intends to distribute income, if any, monthly, and capital gains, if any, at least annually.
