Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	NOTE 1 - ORGANIZATION ProShares Trust II (the “Trust”) is a Delaware statutory trust formed on October 9, 2007 and is currently organized into separate series (each, a “Fund” and collectively, the “Funds”). As of June 30, 2023, the following sixteen series of the Trust have commenced investment operations: (i) ProShares VIX Short-Term Futures ETF and ProShares VIX Mid-Term Futures ETF (each, a “Matching VIX Fund” and collectively, the “Matching VIX Funds”); (ii) ProShares Short VIX Short-Term Futures ETF and ProShares Ultra VIX Short-Term Futures ETF (each, a “Geared VIX Fund” and collectively, the “Geared VIX Funds”); and (iii) ProShares UltraShort Bloomberg Crude Oil, ProShares UltraShort Bloomberg Natural Gas, ProShares UltraShort Gold, ProShares UltraShort Silver, ProShares UltraShort Euro, ProShares UltraShort Yen, ProShares Ultra Bloomberg Crude Oil, ProShares Ultra Bloomberg Natural Gas, ProShares Ultra Gold, ProShares Ultra Silver, ProShares Ultra Euro and ProShares Ultra Yen (each, a “Leveraged Fund” and collectively, the “Leveraged Funds”); Each of the Funds listed above issues common units of beneficial interest (“Shares”), which represent units of fractional undivided beneficial interest in and ownership of only that Fund. The Shares of each Fund, other than the Matching VIX Funds and the Geared VIX Funds, are listed on the NYSE Arca, Inc. (“NYSE Arca”). The Matching VIX Funds and the Geared VIX Funds are listed on the Cboe BZX Exchange (“Cboe BZX”). The Leveraged Funds and the Geared VIX Funds, are collectively referred to as the “Geared Funds” in these Notes to Financial Statements. The Geared VIX Funds and the Matching VIX Funds are collectively referred to as the “VIX Funds” in these Notes to Financial Statements. On March 11, 2022, ProShares Capital Management LLC announced that it planned to close and liquidate ProShares UltraShort Australian Dollar ETF (ticker symbol: CROC) and ProShares Short Euro ETF (ticker symbol: EUFX), together, the “liquidated funds”. The last day the liquidated funds accepted creation orders was on May 2, 2022. Trading in each liquidated fund was suspended prior to market open on May 3, 2022. Proceeds of the liquidation were sent to shareholders on May 12, 2022 (the “Distribution Date”). From May 3, 2022 through the Distribution Date, shares of the liquidated funds did not trade on the NYSE Arca nor was there a secondary market for the shares. Any shareholders that remained in a liquidated fund on the Distribution Date automatically had their shares redeemed for cash at the current net asset value on May 12, 2022. The Trust had no operations prior to November 24, 2008, other than matters relating to its organization, the registration of each series under the Securities Act of 1933, as amended, and the sale and issuance to ProShare Capital Management LLC (the “Sponsor”) of fourteen Shares at an aggregate purchase price of $350 in each of the following Funds: ProShares UltraShort Bloomberg Crude Oil, ProShares UltraShort Gold, ProShares UltraShort Silver, ProShares UltraShort Euro, ProShares UltraShort Yen, ProShares Ultra Bloomberg Crude Oil, ProShares Ultra Gold, ProShares Ultra Silver, ProShares Ultra Euro and ProShares Ultra Yen. Groups of Funds are collectively referred to in several different ways. References to “Short Funds,” “UltraShort Funds,” or “Ultra Funds” refer to the different Funds based upon their investment objectives, but without distinguishing among the Funds’ benchmarks. References to “Commodity Index Funds,” “Commodity Funds” and “Currency Funds” refer to the different Funds according to their general benchmark categories without distinguishing among the Funds’ investment objectives or Fund-specific benchmarks. References to “VIX Funds” refer to the different Funds based upon their investment objective and their general benchmark categories. The “Short” Fund seeks daily investment results, before fees and expenses, that correspond to one-half the inverse (-0.5x) of the daily performance of its corresponding benchmark. Each “UltraShort” Fund seeks daily investment results, before fees and expenses, that correspond to two times the inverse (-2x) of the daily performance of its corresponding benchmark. Each “Ultra” Fund seeks daily investment results, before fees and expenses, that correspond to either one and one-half times (1.5x) or two times (2x) the daily performance of its corresponding benchmark. Each Matching VIX Fund seeks investment results, before fees and expenses, both for a single day The Geared Funds do not seek to achieve their stated investment objectives over a period of time greater than a single day because mathematical compounding prevents the Geared Funds from achieving such results. Accordingly, results over periods of time greater than a single day should not be expected to be a simple multiple (e.g., -0.5x, -2x, 1.5x, or 2x) of the period return of the corresponding benchmark and will likely differ significantly. Share Splits and Reverse Share Splits The table below includes reverse Share splits for the Funds during the six months June 30, 2023, and during the year ended December 31, 2022. The ticker symbols for these Funds did not change, and each Fund continues to trade on its primary listing exchange, as applicable. Fund Execution Date Type of Split Date Trading ProShares UltraShort Bloomberg Natural Gas January 13, 2022 1-for-5 reverse Share split January 14, 2022 ProShares UltraShort Yen May 25, 2022 2-for-1 forward Share split May 26, 2022 ProShares Ultra Bloomberg Crude Oil May 25, 2022 4-for-1 forward Share split May 26, 2022 ProShares UltraShort Bloomberg Natural Gas May 25, 2022 1-for-4 reverse Share split May 26, 2022 ProShares UltraShort Bloomberg Crude Oil May 25, 2022 1-for-5 reverse Share split May 26, 2022 ProShares Ultra Bloomberg Natural Gas June 23, 2023 1-for-20 reverse Share split June 24, 2023 ProShares Ultra VIX Short-Term Futures June 23, 2023 1-for-10 reverse Share split June 24, 2023 ProShares VIX Short-Term Futures June 23, 2023 1-for-5 reverse Share split June 24, 2023 The reverse splits were applied retroactively for all periods presented, reducing the number of Shares outstanding for each of the Funds, and resulted in a proportionate increase in the price per Share and per Share information of each such Fund. Therefore, the reverse splits did not change the aggregate net asset value of a shareholder’s investment at the time of the reverse split. The forward splits were applied retroactively for all periods presented, increasing the number of Shares outstanding for each of the Funds, and resulted in a proportionate decrease in the price per Share and per Share information of each such Fund. Therefore, the forward splits did not change the aggregate net asset value of a shareholder’s investment at the time of the forward split.

Accounting Policies [Abstract]
Significant Accounting Policies	NOTE 2 – SIGNIFICANT ACCOUNTING POLICIES Each Fund is an investment company, as defined by Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 946 “Financial Services — Investment Companies.” As such, the Funds follow the investment company accounting and reporting guidance. The following is a summary of significant accounting policies followed by each Fund, as applicable, in preparation of its financial statements. These policies are in conformity with accounting principles generally accepted in the United States of America (“GAAP”). The accompanying unaudited financial statements were prepared in accordance with GAAP for interim financial information and with the instructions for Form 10-Q and the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). In the opinion of management, all material adjustments, consisting only of normal recurring adjustments, considered necessary for a fair statement of the interim period financial statements have been made. Interim period results are not necessarily indicative of results for a full-year period. These financial statements and the notes thereto should be read in conjunction with the Trust’s and the Funds’ financial statements included in the Trust’s Annual Report on Form 10-K for the year ended December 31, 2022, as filed with the SEC on February 28, 2023. Use of Estimates & Indemnifications The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. In the normal course of business, the Trust enters into contracts that contain a variety of representations which provide general indemnifications. The Trust’s maximum exposure under these arrangements cannot be known; however, the Trust expects any risk of material or significant loss to be remote. Basis of Presentation Pursuant to rules and regulations of the SEC, these financial statements are presented for the Trust as a whole, as the SEC registrant, and for each Fund individually. The debts, liabilities, obligations and expenses incurred, contracted for or otherwise existing with respect to a particular Fund shall be enforceable only against the assets of such Fund and not against the assets of the Trust generally or any other Fund. Accordingly, the assets of each Fund of the Trust include only those funds and other assets that are paid to, held by or distributed to the Trust for the purchase of Shares in that Fund. Statements of Cash Flows The cash amounts shown in the Statements of Cash Flows are the amounts reported as cash in the Statements of Financial Condition dated June 30, 2023 and 2022, and represents cash, segregated cash balances with brokers for futures contracts, segregated cash with brokers for swap agreements and segregated cash with brokers for foreign currency forward agreements but does not include short-term investments. Final Net Asset Value for Fiscal Period The cut-off times and the times of the calculation of the Funds’ final net asset value for creation and redemption of fund Shares for the six months ended June 30, 2023 were typically as follows. All times are Eastern Standard Time: Fund Create/Redeem NAV Calculation NAV Ultra Silver and UltraShort Silver 1:00 p.m. 1:25 p.m. June 30, 2023 Ultra Gold and UltraShort Gold 1:00 p.m. 1:30 p.m. June 30, 2023 Ultra Bloomberg Crude Oil, Ultra Bloomberg Natural Gas, UltraShort Bloomberg Crude Oil and UltraShort Bloomberg Natural Gas 2:00 p.m. 2:30 p.m. June 30, 2023 Ultra Euro, Ultra Yen, UltraShort Euro and UltraShort Yen 3:00 p.m. 4:00 p.m. June 30, 2023 Short VIX Short-Term Futures ETF, Ultra VIX Short-Term Futures ETF, VIX Mid-Term Futures ETF and VIX Short-Term Futures ETF 2:00 p.m. 4:00 p.m. June 30, 2023 * Although the Funds’ shares may continue to trade on secondary markets subsequent to the calculation of the final NAV, these times represent the final opportunity to transact in creation or redemption units for the six months ended June 30, 2023. Market value per Share is determined at the close of the applicable primary listing exchange and may be from when the Funds’ NAV per Share is calculated. For financial reporting purposes, the Funds value transactions based upon the final closing price in their primary markets. Accordingly, the investment valuations in these financial statements may differ from those used in the calculation of certain of the Funds’ final creation/redemption NAV for the six months ended June 30, 2023. Investment Valuation Short-term investments are valued at amortized cost which approximates fair value for daily NAV purposes. For financial reporting purposes, short-term investments are valued at their market price using information provided by a third-party pricing service or market quotations. In each of these situations, valuations are typically categorized as Level I in the fair value hierarchy. Derivatives (e.g., futures contracts, options, swap agreements, forward agreements and foreign currency forward contracts) are generally valued using independent sources and/or agreements with counterparties or other procedures as determined by the Sponsor. Futures contracts, except for those entered into by the Gold, Silver and UltraShort Euro Fund, are generally valued at the last settled price on the applicable exchange on which that future trades. Futures contracts entered into by the Gold, Silver and UltraShort Euro Fund are generally valued at the last sales price prior to the time at which the NAV per Share of a Fund is determined. For financial reporting purposes, all futures contracts are generally valued at the last settled price. Futures contracts valuations are typically categorized as Level I in the fair value hierarchy. Swap agreements, forward agreements and foreign currency forward contracts valuations are typically categorized as Level II in the fair value hierarchy. The Sponsor may in its sole discretion choose to determine a fair value price as the basis for determining the market value of such position. Such fair value prices would generally be determined based on available inputs about the current value of the underlying financial instrument or commodity and would be based on principles that the Sponsor deems fair and equitable so long as such principles are consistent with industry standards. The Sponsor may fair value an asset of a Fund pursuant to the policies the Sponsor has adopted. Depending on the source and relevant significance of valuation inputs, these instruments may be classified as Level II or Level III in the fair value hierarchy. Fair value pricing may require subjective determinations about the value of an investment. While the Funds’ policies are intended to result in a calculation of its respective Fund’s NAV that fairly reflects investment values as of the time of pricing, such Fund cannot ensure that fair values determined by the Sponsor or persons acting at their direction would accurately reflect the price that a Fund could obtain for an investment if it were to dispose of that investment as of the time of pricing (for instance, in a forced or distressed sale). The prices used by such Fund may differ from the value that would be realized if the investments were sold and the differences could be material to the financial statements. Fair Value of Financial Instruments The Funds disclose the fair value of their investments in a hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The disclosure requirements establish a fair value hierarchy that distinguishes between: (1) market participant assumptions developed based on market data obtained from sources independent of the Funds (observable inputs); and (2) the Funds’ own assumptions about market participant assumptions developed based on the best information available under the circumstances (unobservable inputs). The three levels defined by the disclosure requirements hierarchy are as follows: Level I – Quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level II – Inputs other than quoted prices included within Level I that are observable for the asset or liability, either directly or indirectly. Level II assets include the following: quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability, and inputs that are derived principally from or corroborated by observable market data by correlation or other means (market-corroborated inputs). Level III – Unobservable pricing input at the measurement date for the asset or liability. Unobservable inputs shall be used to measure fair value to the extent that observable inputs are not available. In some instances, the inputs used to measure fair value might fall in different levels of the fair value hierarchy. The level in the fair value hierarchy within which the fair value measurement in its entirety falls is determined based on the lowest input level that is significant to the fair value measurement in its entirety. Fair value measurements also require additional disclosure when the volume and level of activity for the asset or liability have significantly decreased, as well as when circumstances indicate that a transaction is not orderly.

Only current day’s variation margin is reported within the Statements of Financial Condition in receivable/payable on open futures. There were no transfers into or out of Level 3 for the quarter ended June 30, 2023 or the year end December 31, 2022. The inputs or methodology used for valuing investments are not necessarily an indication of the risk associated with investing in those securities. Investment Transactions and Related Income Investment transactions are recorded on the trade date. All such transactions are recorded on the identified cost basis and marked to market daily. Unrealized appreciation (depreciation) on open contracts are reflected in the Statements of Financial Condition and changes in the unrealized appreciation (depreciation) between periods are reflected in the Statements of Operations. Interest income is recognized on an accrual basis and includes, where applicable, the amortization of premium or discount, and is reflected as Interest Income in the Statement of Operations. Brokerage Commissions and Futures Account Fees Each Fund pays its respective brokerage commissions, including applicable exchange fees, National Futures Association (“NFA”) fees, give-up fees, pit brokerage fees and other transaction related fees and expenses charged in connection with trading activities for each Fund’s investment in U.S. Commodity Futures Trading Commission (“CFTC”) regulated investments. The effects of trading spreads, financing costs/fees associated with Financial Instruments, and costs relating to the purchase of U.S. Treasury securities or similar high credit quality short-term fixed-income would also be borne by the Funds. Brokerage commissions on futures contracts are recognized on a half-turn basis (e.g., the first half is recognized when the contract is purchased (opened) and the second half is recognized when the transaction is closed). The Sponsor is currently paying brokerage commissions on VIX futures contracts for the Matching VIX Funds that exceed variable create/redeem fees collected by more than 0.02% of the Matching VIX Fund’s average net assets ann ually. Federal Income Tax Each Fund is registered as a series of a Delaware statutory trust and is treated as a partnership for U.S. federal income tax purposes. Accordingly, no Fund expects to incur U.S. federal income tax liability; rather, each beneficial owner of a Fund’s Shares is required to take into account its allocable share of its Fund’s income, gain, loss, deductions and other items for its Fund’s taxable year ending with or within the beneficial owner’s taxable year. Management of the Funds has reviewed all open tax years and major jurisdictions (i.e., the last four tax year ends and the interim tax period since then, as applicable) and concluded that there is no tax liability resulting from unrecognized tax benefits relating to uncertain income tax positions taken or expected to be taken in future tax returns. The Funds are also not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months. On an ongoing basis, management monitors its tax positions taken under the interpretation to determine if adjustments to conclusions are necessary based on factors including, but not limited to, on-going analysis of tax law, regulation, and interpretations thereof.

Investments, Debt and Equity Securities [Abstract]
Investments	NOTE 3 – INVESTMENTS Short-Term Investments The Funds may purchase U.S. Treasury Bills, agency securities, and other high-credit quality short-term fixed income or similar securities with original maturities of one year or less. A portion of these investments may be posted as collateral in connection with swap agreements, futures, and/or forward contracts. Accounting for Derivative Instruments In seeking to achieve each Fund’s investment objective, the Sponsor uses a mathematical approach to investing. Using this approach, the Sponsor determines the type, quantity and mix of investment positions, including derivative positions, which the Sponsor believes in combination, should produce returns consistent with a Fund’s objective. All open derivative positions at period end are reflected on each respective Fund’s Schedule of Investments. Certain Funds utilized a varying level of derivative instruments in conjunction with investment securities in seeking to meet their investment objectives during the period. While the volume of open positions may vary on a daily basis as each Fund transacts derivatives contracts in order to achieve the appropriate exposure to meet its investment objective, the volume of these open positions relative to the net assets of each respective Fund at the date of this report is generally representative of open positions throughout the reporting period. Following is a description of the derivative instruments used by the Funds during the reporting period, including the primary underlying risk exposures related to each instrument type. Futures Contracts The Funds may enter into futures contracts to gain exposure to changes in the value of, or as a substitute for investing directly in (or shorting), an underlying Index, currency or commodity. A futures contract obligates the seller to deliver (and the purchaser to accept) the future delivery of a specified quantity and type of asset at a specified time and place. The contractual obligations of a buyer or seller may generally be satisfied by taking or making physical delivery of the underlying commodity, if applicable, or by making an offsetting sale or purchase of an identical futures contract on the same or linked exchange before the designated date of delivery, or by cash settlement at expiration of contract. Upon entering into a futures contract, each Fund is required to deposit and maintain as collateral at least such initial margin as required by the exchange on which the transaction is affected. The initial margin is segregated as cash and/or securities balances with brokers for futures contracts, as disclosed in the Statements of Financial Condition, and is restricted as to its use. The Funds that enter into futures contracts maintain collateral at the broker in the form of cash and/or securities. Pursuant to the futures contract, each Fund generally agrees to receive from or pay to the broker(s) an amount of cash equal to the daily fluctuation in value of the futures contract. Such receipts or payments are known as variation margin and are recorded by each Fund as unrealized gains or losses. Each Fund will realize a gain or loss upon closing of a futures transaction. Futures contracts involve, to varying degrees, elements of market risk (specifically exchange rate sensitivity, commodity price risk or equity market volatility risk) and exposure to loss in excess of the amount of variation margin. The face or contract amounts reflect the extent of the total exposure each Fund has in the particular classes of instruments. Additional risks associated with the use of futures contracts are imperfect correlation between movements in the price of the futures contracts and the market value of the underlying Index or commodity and the possibility of an illiquid market for a futures contract. With futures contracts, there is minimal but some counterparty risk to the Funds since futures contracts are exchange-traded and the credit risk resides with the Funds’ clearing broker or clearinghouse itself. Many futures exchanges and boards of trade limit the amount of fluctuation permitted in futures contract prices during a single trading day. Once the daily limit has been reached in a particular contract, no trades may be made that day at a price beyond that limit or trading may be suspended for specified times during the trading day. Futures contracts prices could move to the limit for several consecutive trading days with little or no trading, thereby preventing prompt liquidation of futures positions and potentially subjecting a Fund to substantial losses. If trading is not possible, or if a Fund determines not to close a futures position in anticipation of adverse price movements, the Fund will be required to make daily cash payments of variation margin. The risk the Fund will be unable to close out a futures position will be minimized by entering into such transactions on a national exchange with an active and liquid secondary market. Option Contracts An option is a contract that gives the buyer the right, but not the obligation, to buy or sell a specified quantity of a commodity or other instrument at a specific (or strike) price within a specified period of time, regardless of the market price of that instrument. There are two types of options: calls and puts. A call option conveys to the option buyer the right to purchase a particular futures contract at a stated price at any time during the life of the option. A put option conveys to the option buyer the right to sell a particular futures contract at a stated price at any time during the life of the option. Options written by a Fund may be wholly or partially covered (meaning that the Fund holds an offsetting position) or uncovered. In the case of the purchase of an option, the risk of loss of an investor’s entire investment (i.e., the premium paid plus transaction charges) reflects the nature of an option as a wasting asset that may become worthless when the option expires. Where an option is written or granted (i.e., sold) uncovered, the seller may be liable to pay substantial additional margin, and the risk of loss is unlimited, as the seller will be obligated to deliver, or take delivery of, an asset at a predetermined price which may, upon exercise of the option, be significantly different from the market value. When a Fund writes a call or put, an amount equal to the premium received is recorded and subsequently marked to market to reflect the current value of the option written. Premiums received from writing options which expire are treated as realized gains. Premiums received from writing options which are exercised or closed are added to the proceeds or offset against amounts paid on the underlying futures, swap, security or currency transaction to determine the realized gain (loss). When a Fund purchases an option, the Fund pays a premium which is included as an asset on the Statement of Financial Condition and subsequently marked to market to reflect the current value of the option. Premiums paid for purchasing options which expire are treated as realized losses. The risk associated with purchasing put and call options is limited to the premium paid. Premiums paid for purchasing options which are exercised or closed are added to the amounts paid or offset against the proceeds on the underlying investment transaction to determine the realized gain (loss) when the underlying transaction is executed. Certain options transactions may subject the writer (seller) to unlimited risk of loss in the event of an increase in the price of the contract to be purchased or delivered. The value of a Fund’s options transactions, if any, will be affected by, among other things, changes in the value of a Fund’s underlying benchmark relative to the strike price, changes in interest rates, changes in the actual and implied volatility of the Fund’s underlying benchmark, and the remaining time until the options expire, or any combination thereof. The value of the options should not be expected to increase or decrease at the same rate as the level of the Fund’s underlying benchmark, which may contribute to tracking error. Options may be less liquid than certain other securities. A Fund’s ability to trade options will be dependent on the willingness of counterparties to trade such options with the Fund. In a less liquid market for options, a Fund may have difficulty closing out certain option positions at desired times and prices. A Fund may experience substantial downside from specific option positions and certain option positions may expire worthless. Over-the-counter options generally are not assignable except by agreement between the parties concerned, and no party or purchaser has any obligation to permit such assignments. The over-the-counter market for options is relatively illiquid, particularly for relatively small transactions. The use of options transactions exposes a Fund to liquidity risk and counterparty credit risk, and in certain circumstances may expose the Fund to unlimited risk of loss. The Funds may buy and sell options on futures contracts, which may present even greater volatility and risk of loss. Each Oil Fund (ProShares UltraShort Bloomberg Crude Oil and ProShares Ultra Bloomberg Crude Oil) may, but is not required to, seek to use swap agreements or options strategies that limit losses (i.e., have “floors”) or are otherwise designed to prevent the Fund’s net asset value from going to zero. These investment strategies will not prevent an Oil Fund from losing value, and their use may not prevent a Fund’s NAV from going to zero. Rather, they are intended to allow an Oil Fund to preserve a small portion of its value in the event of significant movements in its benchmark or Financial Instruments based on its benchmark. There can be no guarantee that an Oil Fund will be able to implement such strategies, continue to use such strategies, or that such strategies will be successful. Each Oil Fund will incur additional costs as a result of using such strategies. Use of strategies designed to limit losses may also place “caps” or “ceilings” on performance and could significantly limit Fund gains, could cause a Fund to perform in a manner not consistent with its investment objective and could otherwise have a significant impact on Fund performance. Swap Agreements Certain of the Funds enter into swap agreements for purposes of pursuing their investment objectives or as a substitute for investing directly in (or shorting) an underlying Index, currency or commodity, or to create an economic hedge against a position. Swap agreements are two-party contracts that have traditionally been entered into primarily with institutional investors in over-the-counter (“OTC”) markets for a specified period, ranging from a day to more than one year. However, the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) provides for significant reforms of the OTC derivative markets, including a requirement to execute certain swap transactions on a CFTC-regulated market and/or to clear such transactions through a CFTC-regulated central clearing organization. In a standard swap transaction, two parties agree to exchange the returns earned or realized on a particular predetermined investment, instrument or Index in exchange for a fixed or floating rate of return in respect of a predetermined notional amount. Transaction or commission costs are reflected in the benchmark level at which the transaction is entered into. The gross returns to be exchanged are calculated with respect to a notional amount and the benchmark returns to which the swap is linked. Swap agreements do not involve the delivery of underlying instruments. Generally, swap agreements entered into by the Funds calculate and settle the obligations of the parties to the agreement on a “net basis” with a single payment. Consequently, each Fund’s current obligations (or rights) under a swap agreement will generally be equal only to the net amount to be paid or received under the agreement based on the relative values of such obligations (or rights) (the “net amount”). In a typical swap agreement entered into by a Matching VIX Fund or Ultra Fund, the Matching VIX Fund or Ultra Fund would be entitled to settlement payments in the event the level of the benchmark increases and would be required to make payments to the swap counterparties in the event the level of the benchmark decreases, adjusted for any transaction costs or trading spreads on the notional amount the Funds may pay. In a typical swap agreement entered into by a Short Fund or an UltraShort Fund, the Short Fund or UltraShort Fund would be required to make payments to the swap counterparties in the event the level of the benchmark increases and would be entitled to settlement payments in the event the level of the benchmark decreases, adjusted for any transaction costs or trading spreads on the notional amount the Funds may pay. The net amount of the excess, if any, of each Fund’s obligations over its entitlements with respect to each OTC swap agreement is accrued on a daily basis and an amount of cash and/or securities having an aggregate value at least equal to such accrued excess is maintained for the benefit of the counterparty in a segregated account by the Funds’ Custodian. The net amount of the excess, if any, of each Fund’s entitlements over its obligations with respect to each OTC swap agreement is accrued on a daily basis and an amount of cash and/or securities having an aggregate value at least equal to such accrued excess is maintained for the benefit of the Fund in a segregated account by a third party custodian. Until a swap agreement is settled in cash, the gain or loss on the notional amount less any transaction costs or trading spreads payable by each Fund on the notional amount are recorded as “unrealized appreciation or depreciation on swap agreements” and, when cash is exchanged, the gain or loss realized is recorded as “realized gains or losses on swap agreements.” Swap agreements are generally valued at the last settled price of the benchmark referenced asset. Swap agreements contain various conditions, events of default, termination events, covenants and representations. The triggering of certain events or the default on certain terms of the agreement could allow a party to terminate a transaction under the agreement and request immediate payment in an amount equal to the net positions owed to the party under the agreement. This could cause a Fund to have to enter into a new transaction with the same counterparty, enter into a transaction with a different counterparty or seek to achieve its investment objective through any number of different investments or investment techniques. Swap agreements involve, to varying degrees, elements of market risk and exposure to loss in excess of the unrealized gain/loss reflected. The notional amounts reflect the extent of the total investment exposure each Fund has under the swap agreement, which may exceed the NAV of each Fund. Additional risks associated with the use of swap agreements are imperfect correlations between movements in the notional amount and the price of the underlying reference Index and the inability of counterparties to perform. Each Fund bears the risk of loss of the amount expected to be received under a swap agreement in the event of the default or bankruptcy of a swap agreement counterparty. A Fund will typically enter into swap agreements only with major global financial institutions. The creditworthiness of each of the firms that is a party to a swap agreement is monitored by the Sponsor. The Sponsor may use various techniques to minimize credit risk including early termination and payment, using different counterparties, limiting the net amount due from any individual counterparty and generally requiring collateral to be posted by the counterparty in an amount approximately equal to that owed to the Funds. All of the outstanding swap agreements at June 30, 2023 contractually terminate within one month but may be terminated without penalty by either party at any time. Upon termination, the Fund is obligated to pay or receive the “unrealized appreciation or depreciation” amount. The Funds, as applicable, collateralize swap agreements by segregating or designating cash and/or certain securities as indicated on the Statements of Financial Condition or Schedules of Investments. As noted above, collateral posted in connection with OTC derivative transactions is held for the benefit of the counterparty in a segregated tri-party account at the Custodian to protect the counterparty against non-payment by the Funds. The collateral held in this account is restricted as to its use. In the event of a default by the counterparty, the Funds will seek withdrawal of this collateral from the segregated account and may incur certain costs in exercising its right with respect to the collateral. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Funds may experience significant delays in obtaining any recovery in a bankruptcy or other reorganizational proceeding. The Funds may obtain only limited recovery or may obtain no recovery in such circumstances. The Funds remain subject to credit risk with respect to the amount they expect to receive from counterparties. However, the Funds have sought to mitigate these risks in connection with OTC swaps by generally requiring that the counterparties for each Fund agree to post collateral for the benefit of the Fund, marked to market daily, in an amount approximately equal to what the counterparty owes the Fund, subject to certain minimum thresholds. In the event of a bankruptcy of a counterparty, such Fund will have direct access to the collateral received from the counterparty, generally as of the day prior to the bankruptcy, because there is a one day time lag between the Fund’s request for collateral and the delivery of such collateral. To the extent any such collateral is insufficient, the Funds will be exposed to counterparty risk as described above, including the possible delays in recovering amounts as a result of bankruptcy proceedings. As of June 30, 2023, the collateral posted by counterparties consisted of cash and/or U.S. Treasury securities. The counterparty/credit risk for cleared derivative transactions is generally lower than for OTC derivatives since generally a clearing organization becomes substituted for each counterparty to a cleared derivative contract and, in effect, guarantees the parties’ performance under the contract as each party to a trade looks only to the clearing organization for performance of financial obligations. In addition, cleared derivative transactions benefit from daily marking-to-market and settlement, and segregation and minimum capital requirements applicable to intermediaries. Forward Contracts Certain of the Funds enter into forward contracts for the purpose of pursuing their investment objectives and as a substitute for investing directly in (or shorting) commodities and/or currencies. A forward contract is an agreement between two parties to purchase or sell a specified quantity of an asset at or before a specified date in the future at a specified price. Forward contracts are typically traded in OTC markets and all details of the contracts are negotiated between the counterparties to the agreement. Accordingly, the forward contracts are valued by reference to the contracts traded in the OTC markets. The contractual obligations of a buyer or seller may generally be satisfied by taking or making physical delivery of the underlying commodity or currency, establishing an opposite position in the contract and recognizing the profit or loss on both positions simultaneously on the delivery date or, in some instances, paying a cash settlement before the designated date of delivery. The forward contracts are adjusted by the daily fluctuation of the underlying commodity or currency and any gains or losses are recorded for financial statement purposes as unrealized gains or losses until the contract settlement date. Forward contracts have traditionally not been cleared or guaranteed by a third party. As a result of the Dodd-Frank Act, the CFTC now regulates non-deliverable forwards (including deliverable forwards where the parties do not take delivery). Certain non-deliverable forward contracts, such as non-deliverable foreign exchange forwards, may be subject to regulation as swap agreements, including mandatory clearing. Changes in the forward markets may entail increased costs and result in increased reporting requirements. The Funds may collateralize OTC forward commodity contracts by segregating or designating cash and/or certain securities as indicated on their Statements of Financial Condition or Schedules of Investments. Such collateral is held for the benefit of the counterparty in a segregated tri-party account at a third party custodian to protect the counterparty against non-payment by the Funds. The collateral held in this account is restricted as to its use. In the event of a default by the counterparty, the Funds will seek withdrawal of this collateral from the segregated account and may incur certain costs in exercising its right with respect to the collateral. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Funds may experience significant delays in obtaining any recovery in a bankruptcy or other reorganizational proceeding. The Funds may obtain only limited recovery or may obtain no recovery in such circumstances. The Funds remain subject to credit risk with respect to the amount they expect to receive from counterparties. However, the Funds have sought to mitigate these risks by generally requiring that the counterparties for each Fund agree to post collateral for the benefit of the Fund, marked to market daily, in an amount approximately equal to what the counterparty owes the Fund, subject to minimum thresholds. In the event of the bankruptcy of a counterparty, the Fund will have direct access to the collateral received from the counterparty, generally as of the day prior to the bankruptcy, because there is a one day time lag between the Fund’s request for collateral and the delivery of such collateral. To the extent any such collateral is insufficient, the Fund will be exposed to counterparty risk as described above, including the possible delays in recovering amounts as a result of bankruptcy proceedings. As of June 30, 2023, the collateral posted by counterparties consisted of cash and/or U.S. Treasury securities. Participants in trading foreign exchange forward contracts often do not require margin deposits, but rely upon internal credit limitations and their judgments regarding the creditworthiness of their counterparties. In recent years, however, many OTC market participants in foreign exchange trading have begun to require their counterparties to post margin. A Fund will typically enter into forward contracts only with major global financial institutions. The creditworthiness of each of the firms that is a party to a forward contract is monitored by the Sponsor. The counterparty/credit risk for cleared derivative transactions is generally lower than for OTC derivatives since generally a clearing organization becomes substituted for each counterparty to a cleared derivative contract and, in effect, guarantees the parties’ performance under the contract as each party to a trade looks only to the clearing organization for performance of financial obligations. In addition, cleared derivative transactions benefit from daily marking-to-market and settlement, and segregation and minimum capital requirements applicable to intermediaries.

Agreements	NOTE 4 – AGREEMENTS Management Fee Each Leveraged Fund, and each Geared VIX Fund, pays the Sponsor a Management Fee, monthly in arrears, in an amount equal to 0.95% per annum of its average daily NAV of such Fund. Each Matching VIX Fund pays the Sponsor a Management Fee, monthly in arrears, in an amount equal to 0.85% per annum of its average daily NAV of such Fund. The Sponsor stopped charging the Management Fee to the ProShares UltraShort Australian Dollar ETF and ProShares Short Euro ETF on May 2, 2022, the date it was determined that liquidation was imminent. The Management Fee is paid in consideration of the Sponsor’s trading advisory services and the other services provided to the Fund that the Sponsor pays directly. From the Management Fee, the Sponsor pays all of the routine operational, administrative and other ordinary expenses of each Fund, generally as determined by the Sponsor, including but not limited to, (i) the fees and expenses of the Administrator, Custodian, Transfer Agent, Distributor (as each is defined below), and ProFunds Distributors, Inc., an affiliated broker-dealer of the Sponsor, as well as accounting and auditing fees and expenses, (ii) any Index licensors for the Funds; and (iii) the normal and expected expenses incurred in connection with the continuous offering of Shares of each Fund after the commencement of its trading operations. Fees associated with a Fund’s trading operations may include expenses such as tax preparation expenses, legal fees not in excess of $100,000 per annum, ongoing SEC registration fees not exceeding 0.021% per annum of the NAV of a Fund and Financial Industry Regulatory Authority (“FINRA”) filing fees, individual Schedule K-1 preparation and mailing fees not exceeding 0.10% per annum of the net assets of a Fund, and report preparation and mailing expenses. Non-Recurring Fees and Expenses Each Fund pays all its non-recurring and unusual fees and expenses, if any, as determined by the Sponsor. Non-recurring and unusual fees and expenses are fees and expenses that are unexpected or unusual in nature, such as legal claims and liabilities, litigation costs or indemnification or other material expenses which are not currently anticipated obligations of the Funds. The Administrator BNY Mellon Asset Servicing, a division of The Bank of New York Mellon (“BNY Mellon”), serves as the Administrator of the Funds (the “Administrator”). The Trust, on its own behalf and on behalf of each Fund, and BNY Mellon have entered into an administration and accounting agreement (the “Administration and Accounting Agreement”) in connection therewith. Pursuant to the terms of the Administration and Accounting Agreement and under the supervision and direction of the Sponsor and the Trust, BNY Mellon prepares and files certain regulatory filings on behalf of the Funds. BNY Mellon may also perform other services for the Funds pursuant to the Administration and Accounting Agreement as mutually agreed upon by the Sponsor, the Trust and BNY Mellon from time to time. The Administrator’s fees are paid on behalf of the Funds by the Sponsor. The Custodian BNY Mellon serves as the Custodian of the Funds (the “Custodian”). The Trust, on its own behalf and on behalf of each Fund, and BNY Mellon have entered into a custody agreement (the “Custody Agreement”) in connection therewith. Pursuant to the terms of the Custody Agreement, BNY Mellon is responsible for the holding and safekeeping of assets delivered to it by the Funds, and performing various administrative duties in accordance with instructions delivered to BNY Mellon by the Funds. The Custodian’s fees are paid on behalf of the Funds by the Sponsor. The Transfer Agent BNY Mellon serves as the Transfer Agent of the Funds (the “Transfer Agent”) for entities that have entered into an Authorized Participant Agreement with one or more of the Funds (“Authorized Participants”) and has entered into a transfer agency and service agreement (the “Transfer Agency and Service Agreement”).Pursuant to the terms of the Transfer Agency and Service Agreement, BNY Mellon is responsible for processing purchase and redemption orders and maintaining records of ownership of the Funds. The Transfer Agent Fees are paid on behalf of the Funds by the Sponsor. The Distributor SEI Investments Distribution Co. (“SEI”) serves as Distributor of the Funds and assists the Sponsor and the Administrator with certain functions and duties relating to distribution and marketing, including taking creation and redemption orders, consulting with the marketing staff of the Sponsor and its affiliates with respect to compliance with the requirements of FINRA and/or the NFA in connection with marketing efforts, and reviewing and filing of marketing materials with FINRA and/or the NFA. SEI retains all marketing materials separately for each Fund, at c/o SEI, One Freedom Valley Drive, Oaks, PA 19456. The Sponsor, on behalf of each Fund, has entered into a Distribution Services Agreement with SEI. The Sponsor pays SEI for performing its duties on behalf of the Funds.

Creation and Redemption of Crea

Creation and Redemption of Creation Units	6 Months Ended

Text Block [Abstract]
Creation and Redemption of Creation Units	NOTE 5 – CREATION AND REDEMPTION OF CREATION UNITS Each Fund issues and redeems shares from time to time, but only in one or more Creation Units. A Creation Unit is a block of 50,000 Shares of a Geared Fund and 25,000 Shares of a Matching VIX Fund. Creation Units may be created or redeemed only by Authorized Participants. As a result of the Share splits and reverse Share splits as described in Note 1, certain redemptions as disclosed in the Statements of Changes in Shareholders’ Equity reflect payment of fractional share balances on beneficial shareholder accounts. Except when aggregated in Creation Units, the Shares are not redeemable securities. Retail investors, therefore, generally will not be able to purchase or redeem Shares directly from or with a Fund. Rather, most retail investors will purchase or sell Shares in the secondary market with the assistance of a broker. Thus, some of the information contained in these Notes to Financial Statements—such as references to the Transaction Fees imposed on purchases and redemptions is not relevant to retail investors. Transaction Fees on Creation and Redemption Transactions The manner by which Creation Units are purchased or redeemed is governed by the terms of the Authorized Participant Agreement and Authorized Participant Procedures Handbook. By placing a purchase order, an Authorized Participant agrees to: (1) deposit cash with the Custodian; and (2) if permitted by the Sponsor in its sole discretion, enter into or arrange for an exchange of futures contract for related position or block trade with the relevant fund whereby the Authorized Participant would also transfer to such Fund a number and type of exchange-traded futures contracts at or near the closing settlement price for such contracts on the purchase order date. Authorized Participants may pay a fixed transaction fee (typically $250) in connection with each order to create or redeem a Creation Unit in order to compensate BNY Mellon, as the Administrator, the Custodian and the Transfer Agent of each Fund and its Shares, for services in processing the creation and redemption of Creation Units and to offset the costs of increasing or decreasing derivative positions. Authorized Participants also may pay a variable transaction fee to the Fund of up to 0.10% (and a variable transaction fee to the Matching VIX Funds of 0.05%) of the value of the Creation Unit that is purchased or redeemed unless the transaction fee is waived or otherwise adjusted by the Sponsor. The Sponsor provides such Authorized Participant with prompt notice in advance of any such waiver or adjustment of the transaction fee. Authorized Participants may sell the Shares included in the Creation Units they purchase from the Funds to other investors in the secondary market. Transaction fees for the three and six months ended June 30, 2023 which are included in the Addition and/or Redemption of Shares on the Statements of Changes in Shareholders’ Equity, were as follows: Fund Three Months Ended Six Months Ended ProShares Short VIX Short-Term Futures ETF $ 49,722 $ 161,936 ProShares Ultra Bloomberg Crude Oil — — ProShares Ultra Bloomberg Natural Gas — — ProShares Ultra Euro — — ProShares Ultra Gold — — ProShares Ultra Silver — — ProShares Ultra VIX Short-Term Futures ETF 389,333 820,351 ProShares Ultra Yen — — ProShares UltraShort Bloomberg Crude Oil — — ProShares UltraShort Bloomberg Natural Gas — — ProShares UltraShort Euro — — ProShares UltraShort Gold — — ProShares UltraShort Silver — — ProShares UltraShort Yen — — ProShares VIX Mid-Term Futures ETF 9,046 15,511 ProShares VIX Short-Term Futures ETF 82,901 167,222 Combined Trust: $ 531,002 $ 1,165,020

Risks and Uncertainties [Abstract]
Risk	NOTE 7 – RISK Correlation and Compounding Risk The Geared Funds do not seek to achieve their stated investment objective over a period of time greater than a single day (as measured from NAV calculation time to NAV calculation time). The return of a Geared Fund for a period longer than a single day is the result of its return for each day compounded over the period and usually will differ in amount and possibly even direction from one-half the inverse (-0.5x), two times the inverse (-2x), one and one-half times (1.5x) the return or two times (2x) the return of the Geared Fund’s benchmark for the period. A Geared Fund will lose money if its benchmark performance is flat over time, and it is possible for a Geared Fund to lose money over time even if the performance of its benchmark increases (or decreases in the case of Short or UltraShort), as a result of daily rebalancing, the benchmark’s volatility, compounding, and other factors. Compounding is the cumulative effect of applying investment gains and losses and income to the principal amount invested over time. Gains or losses experienced over a given period will increase or reduce the principal amount invested from which the subsequent period’s returns are calculated. The effects of compounding will likely cause the performance of a Geared Fund to differ from the Geared Fund’s stated multiple times the return of its benchmark for the same period. The effect of compounding becomes more pronounced as benchmark volatility and holding period increase. The impact of compounding will impact each shareholder differently depending on the period of time an investment in a Geared Fund is held and the volatility of the benchmark during the holding period of an investment in the Geared Fund. Longer holding periods, higher benchmark volatility, inverse exposure and greater leverage each affect the impact of compounding on a Geared Fund’s returns. Daily compounding of a Geared Fund’s investment returns can dramatically and adversely affect its longer-term performance during periods of high volatility. Volatility may be at least as important to a Geared Fund’s return for a period as the return of the Geared Fund’s underlying benchmark. The Matching VIX Funds seek to achieve their stated investment objective over time. Each Ultra and UltraShort Fund uses leverage and should produce daily returns that are more volatile than that of its benchmark. For example, the daily return of an Ultra with a 1.5x or 2x multiple should be approximately one and one-half or two times as volatile on a daily basis as is the return of a fund with an objective of matching the same benchmark. The daily return of an UltraShort Fund is designed to return two times the inverse (-2x) of the return that would be expected of a fund with an objective of matching the same benchmark. The Geared Funds are not appropriate for all investors and present significant risks not applicable to other types of funds. The Leveraged Funds use leverage and are riskier than similarly benchmarked exchange-traded funds that do not use leverage. An investor should only consider an investment in a Geared Fund if he or she understands the consequences of seeking daily leveraged, daily inverse or daily inverse leveraged investment results. Shareholders who invest in the Funds should actively manage and monitor their investments, as frequently as daily. While the Funds seek to meet their investment objectives, there is no guarantee they will do so. Factors that may affect a Fund’s ability to meet its investment objective include: (1) the Sponsor’s ability to purchase and sell Financial Instruments in a manner that correlates to a Fund’s objective; (2) an imperfect correlation between the performance of Financial Instruments held by a Fund and the performance of the applicable benchmark; (3) bid-ask spreads on such Financial Instruments; (4) fees, expenses, transaction costs, financing costs associated with the use of Financial Instruments and commission costs; (5) holding or trading instruments in a market that has become illiquid or disrupted; (6) a Fund’s Share prices being rounded to the nearest cent and/or valuation methodology; (7) changes to a benchmark Index that are not disseminated in advance; (8) the need to conform a Fund’s portfolio holdings to comply with investment restrictions or policies or regulatory or tax law requirements; (9) early and unanticipated closings of the markets on which the holdings of a Fund trade, resulting in the inability of the Fund to execute intended portfolio transactions; (10) accounting standards; and (11) differences caused by a Fund obtaining exposure to only a representative sample of the components of a benchmark, over weighting or under weighting certain components of a benchmark or obtaining exposure to assets that are not included in a benchmark. A number of factors may affect a Geared Fund’s ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that a Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent a Geared Fund from achieving its investment objective. In order to achieve a high degree of correlation with their underlying benchmarks, the Geared Funds seek to rebalance their portfolios daily to keep exposure consistent with their investment objectives. Being materially under- or over-exposed to the benchmark may prevent such Geared Funds from achieving a high degree of correlation with such benchmark. Market disruptions or closure, large amounts of assets into or out of the Geared Funds, regulatory restrictions, extreme market volatility, and other factors will adversely affect such Funds’ ability to adjust exposure to requisite levels. The target amount of portfolio exposure is impacted dynamically by the benchmarks’ movements during each day. Other things being equal, more significant movement in the value of its benchmark up or down will require more significant adjustments to a Fund’s portfolio. Because of this, it is unlikely that the Geared Funds will be perfectly exposed (i.e., -0.5x, -2x, 1.5x, or 2x, as applicable) to its benchmark at the end of each day, and the likelihood of being materially under- or over-exposed is higher on days when the benchmark levels are volatile near the close of the trading day. Each Geared Fund seeks to rebalance its portfolio on a daily basis. The time and manner in which a Geared Fund rebalances its portfolio may vary from day to day depending upon market conditions and other circumstances at the discretion of the Sponsor. Unlike other funds that do not rebalance their portfolios as frequently, each Geared Fund may be subject to increased trading costs associated with daily portfolio rebalancing in order to maintain appropriate exposure to the underlying benchmarks. Counterparty Risk Each Fund may use derivatives such as swap agreements and forward contracts (collectively referred to in this Counterparty Risk section as “derivatives”) in the manner described herein as a means to achieve their respective investment objectives. The use of derivatives by a Fund exposes the Fund to counterparty risks. Regulatory Treatment Derivatives are generally traded in OTC markets and are subject to comprehensive regulation in the United States. Cash-settled forwards are generally regulated as “swaps”, whereas physically settled forwards are generally not subject to regulation (in the case of commodities other than currencies) or subject to the federal securities laws (in the case of securities). Title VII of the Dodd-Frank Act (“Title VII”) created a regulatory regime for derivatives, with the CFTC responsible for the regulation of swaps and the SEC responsible for the regulation of “security-based swaps.” Although some of the SEC requirements have not yet been made effective, the CFTC requirements are largely in place. The CFTC requirements include rules for some of the types of derivatives transactions in which the Funds engages, including mandatory clearing and exchange trading, reporting, and margin for OTC swaps. Title VII also created new categories of regulated market participants, such as “swap dealers,” “security-based swap dealers,” “major swap participants,” and “major security-based swap participants” who are, or will be, subject to significant new capital, registration, recordkeeping, reporting, disclosure, business conduct and other regulatory requirements. The regulatory requirements under Title VII continue to be developed and there may be further modifications that could materially and adversely impact the Funds, the markets in which a Fund trades and the counterparties with which the Fund engages in transactions. As noted, all of the relevant CFTC rules may not apply to all of the swap agreements and forward contracts entered into by the Funds. Investors, therefore, may not receive the protection of CFTC regulation or the statutory scheme of the Commodity Exchange Act (the “CEA”) in connection with each Fund’s swap agreements or forward contracts. The lack of regulation in these markets could expose investors to significant losses under certain circumstances, including in the event of trading abuses or financial failure by participants. Counterparty Credit Risk The Funds will be subject to the credit risk of the counterparties to the derivatives. In the case of cleared derivatives, the Funds will have credit risk to the clearing corporation in a similar manner as the Funds would for futures contracts. In the case of uncleared OTC derivatives, the Funds will be subject to the credit risk of the counterparty to the transaction – typically a single bank or financial institution. As a result, a Fund is subject to increased credit risk with respect to the amount it expects to receive from counterparties to uncleared OTC derivatives entered into as part of that Fund’s principal investment strategy. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties or otherwise, a Fund could suffer significant losses on these contracts and the value of an investor’s investment in a Fund may decline. The Funds have sought to mitigate these risks by generally requiring that the counterparties for each Fund agree to post collateral for the benefit of the Fund, marked to market daily, subject to certain minimum thresholds. However, there are no limitations on the percentage of assets each Fund may invest in swap agreements or forward contracts with a particular counterparty. To the extent any such collateral is insufficient or there are delays in accessing the collateral, the Funds will be exposed to counterparty risk as described above, including possible delays in recovering amounts as a result of bankruptcy proceedings. The Funds typically enter into transactions only with major global financial institutions. OTC derivatives of the type that may be utilized by the Funds are generally less liquid than futures contracts because they are not traded on an exchange, do not have uniform terms and conditions, and are generally entered into based upon the creditworthiness of the parties and the availability of credit support, such as collateral, and in general, are not transferable without the consent of the counterparty. These agreements contain various conditions, events of default, termination events, covenants and representations. The triggering of certain events or the default on certain terms of the agreement could allow a party to terminate a transaction under the agreement and request immediate payment in an amount equal to the net positions owed to the party under the agreement. For example, if the level of the Fund’s benchmark has a dramatic intraday move that would cause a material decline in the Fund’s NAV, the terms of the swap may permit the counterparty to immediately close out the transaction with the Fund. In that event, it may not be possible for the Fund to enter into another swap or to invest in other Financial Instruments necessary to achieve the desired exposure consistent with the Fund’s objective. This, in turn, may prevent the Fund from achieving its investment objective, particularly if the level of the Fund’s benchmark reverses all or part of its intraday move by the end of the day. In addition, cleared derivatives benefit from daily mark-to-market and settlement, and segregation and minimum capital requirements applicable to intermediaries. To the extent the Fund enters into cleared swap transactions, the Fund will deposit collateral with a futures commission merchant in cleared swaps customer accounts, which are required by CFTC regulations to be separate from the futures commission merchant’s proprietary collateral posted for cleared swaps transactions. Cleared swap customer collateral is subject to regulations that closely parallel the regulations governing customer segregated funds for futures transactions but provide certain additional protections to cleared swaps collateral in the event of a clearing broker or clearing broker customer default. For example, in the event of a default of both the clearing broker and a customer of the clearing broker, a clearing house is only permitted to access the cleared swaps collateral in the legally separate (but operationally comingled) account of the defaulting cleared swap customer of the clearing broker, as opposed to the treatment of futures customer segregated funds, under which the clearing house may access all of the commingled futures customer segregated funds of a defaulting clearing broker. Derivatives entered into directly between two counterparties do not necessarily benefit from such protections, particularly if entered into with an entity that is not registered as a “swap dealer” with the CFTC. Bilateral OTC derivatives expose the Funds to the risk that a counterparty will not settle a transaction in accordance with its terms and conditions because of a dispute over the terms of the contract (whether or not bona fide) or because of a credit or liquidity problem, thus causing the Funds to suffer a loss. The Sponsor regularly reviews the performance of its counterparties for, among other things, creditworthiness and execution quality. In addition, the Sponsor periodically considers the addition of new counterparties and the counterparties used by a Fund may change at any time. Each day, the Funds disclose their portfolio holdings as of the prior Business Day. Each Fund’s portfolio holdings identifies its counterparties, as applicable. This portfolio holdings information may be accessed through the web on the Sponsor’s website at www.ProShares.com. Each counterparty and/or any of its affiliates may be an Authorized Participant or shareholder of a Fund, subject to applicable law. The counterparty risk for cleared derivatives transactions is generally lower than for OTC derivatives. Once a transaction is cleared, the clearing organization is substituted and is a Fund’s counterparty on the derivative. The clearing organization guarantees the performance of the other side of the derivative. Nevertheless, some risk remains, as there is no assurance that the clearing organization, or its members, will satisfy its obligations to a Fund. Leverage Risk The Leveraged Funds may utilize leverage in seeking to achieve their respective investment objectives and will lose more money in market environments adverse to their respective daily investment objectives than funds that do not employ leverage. The use of leveraged and/or inverse leveraged positions increases the risk of total loss of an investor’s investment, even over periods as short as a single day. For example, because the UltraShort Funds and Ultra Funds (except for the Ultra VIX Short-Term Futures ETF which includes a one and one-half times (1.5x) multiplier) include a two times the inverse (-2x), or a two times (2x) multiplier, a single-day movement in the relevant benchmark approaching 50% at any point in the day could result in the total loss or almost total loss of an investor’s investment if that movement is contrary to the investment objective of the Fund in which an investor has invested, even if such Fund’s benchmark subsequently moves in an opposite direction, eliminating all or a portion of the movement. This would be the case with downward single-day or intraday movements in the underlying benchmark of an Ultra Fund or upward single-day or intraday movements in the benchmark of an UltraShort Fund, even if the underlying benchmark maintains a level greater than zero at all times. Liquidity Risk Financial Instruments cannot always be liquidated at the desired price. It is difficult to execute a trade at a specific price when there is a relatively small volume of buy and sell orders in a market. A market disruption can also make it difficult to liquidate a position or find a swap or forward contract counterparty at a reasonable cost. Market illiquidity may cause losses for the Funds. The large size of the positions which the Funds may acquire increases the risk of illiquidity by both making their positions more difficult to liquidate and increasing the losses incurred while trying to do so. Any type of disruption or illiquidity will potentially be exacerbated due to the fact that the Funds will typically invest in Financial Instruments related to one benchmark, which in many cases is highly concentrated. “Contango” and “Backwardation” Risk In Funds that hold futures contracts, as the futures contracts near expiration, they are generally replaced by contracts that have a later expiration. Thus, for example, a contract purchased and held in November 2022 may specify a January 2023 expiration. As that contract nears expiration, it may be replaced by selling the January 2023 contract and purchasing the contract expiring in March 2023. This process is referred to as “rolling.” Rolling may have a positive or negative impact on performance. For example, historically, the prices of certain types of futures contracts have frequently been higher for contracts with shorter-term expirations than for contracts with longer-term expirations, which is referred to as “backwardation.” In these circumstances, absent other factors, the sale of the January 2023 contract would take place at a price that is higher than the price at which the March 2023 contract is purchased, thereby creating a gain in connection with rolling. While certain types of futures contracts have historically exhibited consistent periods of backwardation, backwardation will likely not exist in these markets at all times. The presence of contango (where prices of contracts are higher in the distant delivery months than in the nearer delivery months due to the costs of long-term storage of a physical commodity prior to delivery or other factors) in certain futures contracts at the time of rolling would be expected to adversely affect an Ultra Fund or a Matching VIX Fund that invests in such futures, and positively affect a Short Fund or an UltraShort Fund that invests in such futures. Similarly, the presence of backwardation in certain futures contracts at the time of rolling such contracts would be expected to adversely affect the Short Funds and UltraShort Funds, and positively affect the Ultra Funds and Matching VIX Funds. Since the introduction of VIX futures contracts, there have frequently been periods where VIX futures prices reflect higher expected volatility levels further out in time. This can result in a loss from “rolling” the VIX futures to maintain the constant weighted average maturity of the applicable VIX Futures Index. Losses from exchanging a lower priced VIX future for a higher priced longer-term future in the rolling process would adversely affect the value of each VIX Futures Index and, accordingly, decrease the return of the Ultra VIX Short-Term Futures ETF and the Matching VIX Funds. Gold and silver have historically exhibited persistent “contango” markets rather than backwardation. Natural gas, like crude oil, moves in and out of backwardation and contango but historically has been in contango most commonly. There have been times where WTI crude oil futures contracts experience “extraordinary contango or extraordinary backwardation”. For example, in April 2020, the market for crude oil futures contracts experienced a period of “extraordinary contango” that resulted in a negative price in the May 2020 WTI crude oil futures contract. In the summer of 2022, the market for crude oil futures contracts experienced a period of extreme backwardation, but normalized towards the end of the year. The futures contracts held by the Funds may experience a period of extraordinary contango or backwardation in the future. If all or a significant portion of the futures contracts held by an Ultra Fund at a future date were to reach a negative price, investors in such Fund could lose their entire investment. Conversely, investors in an UltraShort Fund could suffer significant losses or lose their entire investment if prices reversed or were subject to extraordinary backwardation. The effects of rolling futures contracts under extraordinary contango or backwardation market conditions generally are more exaggerated than rolling futures contracts under more typical contango or backwardation market conditions. Either scenario may result in significant losses. Investments in futures contracts are subject to current position limits and accountability levels established by the exchanges. Accordingly, the Sponsor and the Funds may be required to reduce the size of outstanding positions or be restricted from entering into new positions that would otherwise be taken for a Fund or not trade in certain markets on behalf of the Fund in order to comply with those limits or any future limits. These restrictions, if implemented, could limit the ability of each Fund to invest in additional futures contracts, add to existing positions in the desired amount, or create additional Creation Units and could otherwise have a significant negative impact on Fund operations and performance, decreasing a Fund’s correlation to the performance of its benchmark, and otherwise preventing a Fund from achieving its investment objective. On May 4, 2020, CME imposed a more restrictive position limit in September 2020 WTI oil futures contracts with respect to the Oil Funds. In response to CME’s imposition of a more restrictive position limit, global developments, and other factors, the Sponsor modified certain of the Oil Funds’ investment strategies to invest in longer-dated futures contracts. In early July 2020, in anticipation of the roll of the Oil Funds’ benchmark, and in order to help manage the impact of recent extraordinary conditions and volatility in the markets for crude oil and related Financial Instruments, the Sponsor modified certain of the Oil Funds’ investment strategies to invest in longer-dated futures contracts. Risk that Current Assumptions and Expectations Could Become Outdated As a Result of Global Economic Shocks The onset of the novel coronavirus (COVID-19) and its variants has caused significant shocks to global financial markets and economies, with many governments taking extreme actions in an attempt to slow and contain the spread of COVID-19. These actions have had, and likely will continue to have if reimposed, a severe economic impact on global economies as economic activity in some instances has essentially ceased. As the hospitalization rates and COVID-related deaths continue to fall, the severity of lockdowns and restrictive policies relative to the onset of the COVID-19 pandemic will decrease as the situation gradually improves. Currently the bear market continues to recover from the lockdowns and restrictions that brought economic strain to several industries. Contemporaneous with the onset of the COVID-19 pandemic in the U.S., crude oil markets experienced shocks to the supply of and demand for crude oil. This led to an oversupply of crude oil, which impacted the price of crude oil and futures contracts on crude oil and caused historic volatility in the market for crude oil and crude oil futures contracts. Currently, crude oil prices have increased since the onset of the COVID-19 pandemic. As countries around the world are currently rolling back or eliminating COVID-related restrictions, the demand for oil is expected to increase. For example, China’s ongoing COVID restrictions are expected to be removed and altered, which is expected to increase the demand for crude oil among consumers. On February 24, 2022, Russia commenced a military attack on Ukraine. The ongoing hostilities between the two countries could result in additional widespread conflict and could have a severe adverse effect on the region and the markets for securities and commodities, including oil. As the war continues sanctions on Russian exports in the future could have a significant adverse impact on the Russian economy and related markets. How long such conflict and related events will last and whether it will escalate further cannot be predicted. Impacts from the conflicts and related events could have significant impact on a Fund’s performance, and the value of an investment in a Fund may decline significantly. The price of futures contracts can change quickly and without warning. If the price of WTI crude oil futures contracts in the future were to decline significantly or reach a negative price, investors in the Ultra Crude Oil Fund could suffer significant losses or lose their entire investment.

Significant Accounting Policies (Policies)	6 Months Ended

Accounting Policies [Abstract]
Use of Estimates & Indemnifications	Use of Estimates & Indemnifications The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. In the normal course of business, the Trust enters into contracts that contain a variety of representations which provide general indemnifications. The Trust’s maximum exposure under these arrangements cannot be known; however, the Trust expects any risk of material or significant loss to be remote.
Basis of Presentation	Basis of Presentation Pursuant to rules and regulations of the SEC, these financial statements are presented for the Trust as a whole, as the SEC registrant, and for each Fund individually. The debts, liabilities, obligations and expenses incurred, contracted for or otherwise existing with respect to a particular Fund shall be enforceable only against the assets of such Fund and not against the assets of the Trust generally or any other Fund. Accordingly, the assets of each Fund of the Trust include only those funds and other assets that are paid to, held by or distributed to the Trust for the purchase of Shares in that Fund.
Statements of Cash Flows	Statements of Cash Flows The cash amounts shown in the Statements of Cash Flows are the amounts reported as cash in the Statements of Financial Condition dated June 30, 2023 and 2022, and represents cash, segregated cash balances with brokers for futures contracts, segregated cash with brokers for swap agreements and segregated cash with brokers for foreign currency forward agreements but does not include short-term investments.
Final Net Asset Value for Fiscal Period	Final Net Asset Value for Fiscal Period The cut-off times and the times of the calculation of the Funds’ final net asset value for creation and redemption of fund Shares for the six months ended June 30, 2023 were typically as follows. All times are Eastern Standard Time: Fund Create/Redeem NAV Calculation NAV Ultra Silver and UltraShort Silver 1:00 p.m. 1:25 p.m. June 30, 2023 Ultra Gold and UltraShort Gold 1:00 p.m. 1:30 p.m. June 30, 2023 Ultra Bloomberg Crude Oil, Ultra Bloomberg Natural Gas, UltraShort Bloomberg Crude Oil and UltraShort Bloomberg Natural Gas 2:00 p.m. 2:30 p.m. June 30, 2023 Ultra Euro, Ultra Yen, UltraShort Euro and UltraShort Yen 3:00 p.m. 4:00 p.m. June 30, 2023 Short VIX Short-Term Futures ETF, Ultra VIX Short-Term Futures ETF, VIX Mid-Term Futures ETF and VIX Short-Term Futures ETF 2:00 p.m. 4:00 p.m. June 30, 2023 * Although the Funds’ shares may continue to trade on secondary markets subsequent to the calculation of the final NAV, these times represent the final opportunity to transact in creation or redemption units for the six months ended June 30, 2023. Market value per Share is determined at the close of the applicable primary listing exchange and may be from when the Funds’ NAV per Share is calculated. For financial reporting purposes, the Funds value transactions based upon the final closing price in their primary markets. Accordingly, the investment valuations in these financial statements may differ from those used in the calculation of certain of the Funds’ final creation/redemption NAV for the six months ended June 30, 2023.
Investment Valuation	Investment Valuation Short-term investments are valued at amortized cost which approximates fair value for daily NAV purposes. For financial reporting purposes, short-term investments are valued at their market price using information provided by a third-party pricing service or market quotations. In each of these situations, valuations are typically categorized as Level I in the fair value hierarchy. Derivatives (e.g., futures contracts, options, swap agreements, forward agreements and foreign currency forward contracts) are generally valued using independent sources and/or agreements with counterparties or other procedures as determined by the Sponsor. Futures contracts, except for those entered into by the Gold, Silver and UltraShort Euro Fund, are generally valued at the last settled price on the applicable exchange on which that future trades. Futures contracts entered into by the Gold, Silver and UltraShort Euro Fund are generally valued at the last sales price prior to the time at which the NAV per Share of a Fund is determined. For financial reporting purposes, all futures contracts are generally valued at the last settled price. Futures contracts valuations are typically categorized as Level I in the fair value hierarchy. Swap agreements, forward agreements and foreign currency forward contracts valuations are typically categorized as Level II in the fair value hierarchy. The Sponsor may in its sole discretion choose to determine a fair value price as the basis for determining the market value of such position. Such fair value prices would generally be determined based on available inputs about the current value of the underlying financial instrument or commodity and would be based on principles that the Sponsor deems fair and equitable so long as such principles are consistent with industry standards. The Sponsor may fair value an asset of a Fund pursuant to the policies the Sponsor has adopted. Depending on the source and relevant significance of valuation inputs, these instruments may be classified as Level II or Level III in the fair value hierarchy. Fair value pricing may require subjective determinations about the value of an investment. While the Funds’ policies are intended to result in a calculation of its respective Fund’s NAV that fairly reflects investment values as of the time of pricing, such Fund cannot ensure that fair values determined by the Sponsor or persons acting at their direction would accurately reflect the price that a Fund could obtain for an investment if it were to dispose of that investment as of the time of pricing (for instance, in a forced or distressed sale). The prices used by such Fund may differ from the value that would be realized if the investments were sold and the differences could be material to the financial statements.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The Funds disclose the fair value of their investments in a hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The disclosure requirements establish a fair value hierarchy that distinguishes between: (1) market participant assumptions developed based on market data obtained from sources independent of the Funds (observable inputs); and (2) the Funds’ own assumptions about market participant assumptions developed based on the best information available under the circumstances (unobservable inputs). The three levels defined by the disclosure requirements hierarchy are as follows: Level I – Quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level II – Inputs other than quoted prices included within Level I that are observable for the asset or liability, either directly or indirectly. Level II assets include the following: quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability, and inputs that are derived principally from or corroborated by observable market data by correlation or other means (market-corroborated inputs). Level III – Unobservable pricing input at the measurement date for the asset or liability. Unobservable inputs shall be used to measure fair value to the extent that observable inputs are not available. In some instances, the inputs used to measure fair value might fall in different levels of the fair value hierarchy. The level in the fair value hierarchy within which the fair value measurement in its entirety falls is determined based on the lowest input level that is significant to the fair value measurement in its entirety. Fair value measurements also require additional disclosure when the volume and level of activity for the asset or liability have significantly decreased, as well as when circumstances indicate that a transaction is not orderly. The following table summarizes the valuation of investments at June 30, 2023 using the fair value hierarchy: Level I - Quoted Prices Level II - Other Significant Fund Short-Term U.S. Futures * Foreign Swap Total ProShares Short VIX Short-Term Futures ETF $ 89,727,034 $ 23,929,205 $ — $ — $ 113,656,239 ProShares Ultra Bloomberg Crude Oil 413,997,952 9,418,306 — (1,692,241 ) 421,724,017 ProShares Ultra Bloomberg Natural Gas 298,783,390 248,335,437 — 46,088,257 593,207,084 ProShares Ultra Euro — — 239,688 — 239,688 ProShares Ultra Gold 134,714,723 (5,385,731 ) — (7,053,083 ) 122,275,909 ProShares Ultra Silver 224,344,440 (9,977,916 ) — (18,045,362 ) 196,321,162 ProShares Ultra VIX Short-Term Futures ETF — (79,829,720 ) — — (79,829,720 ) ProShares Ultra Yen — — (857,627 ) — (857,627 ) ProShares UltraShort Bloomberg Crude Oil 74,852,080 12,986,156 — — 87,838,236 ProShares UltraShort Bloomberg Natural Gas 34,829,828 (20,310,332 ) — — 14,519,496 ProShares UltraShort Euro — — (1,758,774 ) — (1,758,774 ) ProShares UltraShort Gold — 970,805 — 440,571 1,411,376 ProShares UltraShort Silver — 958,923 — 845,012 1,803,935 ProShares UltraShort Yen — — 1,979,852 — 1,979,852 ProShares VIX Mid-Term Futures ETF — (9,878,214 ) — — (9,878,214 ) ProShares VIX Short-Term Futures ETF 74,783,454 (29,972,887 ) — — 44,810,567 Combined Trust: $ 1,346,032,901 $ 141,244,032 $ (396,861 ) $ 20,583,154 $ 1,507,463,226 * Includes cumulative appreciation (depreciation) of futures contracts as reported in the Schedule of Investments.

The inputs or methodology used for valuing investments are not necessarily an indication of the risk associated with investing in those securities.
Investment Transactions and Related Income	Investment Transactions and Related Income Investment transactions are recorded on the trade date. All such transactions are recorded on the identified cost basis and marked to market daily. Unrealized appreciation (depreciation) on open contracts are reflected in the Statements of Financial Condition and changes in the unrealized appreciation (depreciation) between periods are reflected in the Statements of Operations. Interest income is recognized on an accrual basis and includes, where applicable, the amortization of premium or discount, and is reflected as Interest Income in the Statement of Operations.
Brokerage Commissions and Futures Account Fees	Brokerage Commissions and Futures Account Fees Each Fund pays its respective brokerage commissions, including applicable exchange fees, National Futures Association (“NFA”) fees, give-up fees, pit brokerage fees and other transaction related fees and expenses charged in connection with trading activities for each Fund’s investment in U.S. Commodity Futures Trading Commission (“CFTC”) regulated investments. The effects of trading spreads, financing costs/fees associated with Financial Instruments, and costs relating to the purchase of U.S. Treasury securities or similar high credit quality short-term fixed-income would also be borne by the Funds. Brokerage commissions on futures contracts are recognized on a half-turn basis (e.g., the first half is recognized when the contract is purchased (opened) and the second half is recognized when the transaction is closed). The Sponsor is currently paying brokerage commissions on VIX futures contracts for the Matching VIX Funds that exceed variable create/redeem fees collected by more than 0.02% of the Matching VIX Fund’s average net assets ann ually.
Federal Income Tax	Federal Income Tax Each Fund is registered as a series of a Delaware statutory trust and is treated as a partnership for U.S. federal income tax purposes. Accordingly, no Fund expects to incur U.S. federal income tax liability; rather, each beneficial owner of a Fund’s Shares is required to take into account its allocable share of its Fund’s income, gain, loss, deductions and other items for its Fund’s taxable year ending with or within the beneficial owner’s taxable year. Management of the Funds has reviewed all open tax years and major jurisdictions (i.e., the last four tax year ends and the interim tax period since then, as applicable) and concluded that there is no tax liability resulting from unrecognized tax benefits relating to uncertain income tax positions taken or expected to be taken in future tax returns. The Funds are also not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months. On an ongoing basis, management monitors its tax positions taken under the interpretation to determine if adjustments to conclusions are necessary based on factors including, but not limited to, on-going analysis of tax law, regulation, and interpretations thereof.
