These adjustments were not significant to the Fund in that they did not affect Shareholder’s equity or Net asset value per share.

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 December 31, 2023, the following sixteen series of the Trust have commenced investment operations: (i) ProShares VIX Short-Term Futures ETF and ProShares VIX Mid-Term 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 Fund,” “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 (-0.5x) (-2x) one-half 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, Forward and Reverse Splits The table below includes forward and reverse Share splits for the Funds during the years ended December 31, 2021, 2022 and 2023.

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. Restatement of Previously Issued Form 10-Q and Form 10-K Filings ProShares Trust II (the “Trust”) identified an error related to the classification of amounts on the Statements of Financial Condition between “Segregated cash balances with brokers for futures contracts” and “Receivable (Payable) on open futures contracts” for Trust filings for each quarterly Form 10-Q and annual Form 10-K filing for the period December 31, 2021, through June 30, 2024, for five Funds. The Statement of Cash Flows was the only other statement affected by these misclassifications. No other financial statement or financial statement disclosure in the Forms 10-Q or Form 10-K filings were affected by these errors. The misclassifications did not change the Shareholder Equity, net asset value per share, or total return of any Fund. The Funds impacted were: ProShares Short VIX Short-Term Futures ETF, ProShares Ultra Bloomberg Natural Gas, ProShares Ultra VIX Short-Term Futures ETF, ProShares UltraShort Bloomberg Natural Gas, and ProShares VIX Short These misclassifications were caused by a misinterpretation of amounts on a futures commission merchant statement and resulted in reclassifications between accounts. There is no impact on the Affected Funds’ performance, investment results, net asset values or income. The impact of these adjustments is shown in the table below.

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”). 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 December 31, 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.

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 year ended December 31, 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.

Brokerage Commissions and Futures Account Fees Each Fund pays its respective brokerage commissions, including applicable exchange fees, National Futures Association (“NFA”) fees, give-up 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., last three years 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

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 over-the-counter 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 over-the-counter 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 December 31, 2023 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 non-payment 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 December 31, 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 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 non-deliverable non-deliverable 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 non-payment 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 December 31, 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 The following tables indicate the location of derivative related items on the Statements of Financial Condition as well as the effect of derivative instruments on the Statements of Operations during the reporting period.

between each Fund and the counterparty to be netted upon an early termination. The party that has the larger payable pays the excess of the larger amount over the smaller amount to the other party. The master netting agreements or similar arrangements do not apply to amounts owed to/from different counterparties. As described above, the Funds utilize derivative instruments to achieve their investment objective during the year. The amounts shown in the Statements of Financial Condition do not take into consideration the effects of legally enforceable master netting agreements or similar arrangements. For financial reporting purposes, the Funds do not offset derivative assets and derivative liabilities that are subject to netting arrangements in the Statements of Financial Condition. The following table presents each Fund’s derivatives by investment type and by counterparty net of amounts available for offset under a master netting agreement and the related collateral received or pledged by the Funds as of December 31, 2023.

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. Each Fund accrues the Management Fee daily at an annualized rate based on its average daily net assets. 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 Non-Recurring Each Fund pays all of its non-recurring Non-recurring 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	12 Months Ended
	Dec. 31, 2023
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 years ended December 31, 2023, 2022 and 2021 which are included in the Addition and/or Redemption of Shares on the Statements of Changes in Shareholders’ Equity, were as follows: Fund Year Ended December 31, 2023 Year Ended Year Ended ProShares Short Euro* $ —  $ —  $ —  ProShares Short VIX Short-Term Futures ETF 242,256 243,685 203,356 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 1,375,762 3,586,278 3,290,059 ProShares Ultra Yen —  —  —  ProShares UltraShort Australian Dollar* —  —  —  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 29,206 54,519 43,993 ProShares VIX Short-Term Futures ETF 273,740 494,781 392,964 Combined Trust: $ 1,920,964 $ 4,379,263 $ 3,930,372 * The operations include the activity of ProShares Short Euro ETF and ProShares UltraShort Australian Dollar ETF through May 12, 2022, the date of liquidation.

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 (-0.5x), (-2x), one-half 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 (-2x) of 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 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, 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 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 (-2x), single-day single-day single-day 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 Fund 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. Natural Disasters and Public Health Disruptions, such as the COVID-19 Natural or environmental disasters, such as earthquakes, fires, floods, hurricanes, tsunamis and other severe weather-related phenomena generally, and widespread disease, including public health disruptions, pandemics and epidemics (for example, COVID-19 isolation, civil unrest, periods of high unemployment, shortages in and disruptions to the medical care and consumer goods and services industries, and other disruptions to important global, local and regional supply chains affected, with potential corresponding results on the operating performance of the Funds and their investments. To attempt to curb the spread of COVID-19, The outbreak of COVID-19 COVID-19, COVID-19, Additionally, public health issues, war and military conflicts (such as Russia’s continued military actions against Ukraine that started in February 2022 and the Israel-Hamas conflict and the ensuing conflict), sanctions, acts of terrorism, sustained elevated inflation, supply chain issues or other events could have a significant negative impact on global financial markets and economies. A widespread crisis may also affect the global economy in ways that cannot necessarily be foreseen at the current time. How long such events will last and whether they will continue or recur cannot be predicted. Impacts from these events could have significant impact on a Fund’s performance, and the value of an investment in the Fund may decline significantly.

Subsequent Events [Abstract]
Subsequent Events	NOTE 8 – SUBSEQUENT EVENTS On March 20, 2024, the Trust announced a 2-for-1 forward split of the shares of beneficial interest of ProShares Short VIX Short-Term Futures (ticker symbol: SVXY) and ProShares UltraShort Bloomberg Natural Gas (ticker symbol: KOLD) an s. For UVXY shareholders who hold a quantity of shares that is not an exact multiple of the Reverse Split ratio (i.e., not a multiple of 5), the Reverse Split will result in the creation of a fractional share. Post-Reverse Split fractional shares will be redeemed for cash and sent to the shareholder’s broker of record. This redemption may cause some shareholders to realize gains or losses, which could be a taxable event for those shareholders. On October 28, 2024, the Trust announced a 2-for-1 forward split of the shares of beneficial interest of ProShares UltraShort Yen (ticker symbol: YCS) and a 1-for-4 reverse split of the shares of beneficial interest of ProShares UltraShort Silver (ticker symbol: ZSL) and ProShares VIX Short-Term Futures (ticker symbol: VIXY) and a 1-for-5 reverse split of the shares of beneficial interest of ProShares Ultra Bloomberg Natural Gas (ticker symbol: BOIL). The splits were effective prior to market open on November 7, 2024, when the funds began trading at its post-split price. The splits were applied retroactively for all periods presented, reducing (increasing) the number of shares outstanding and resulted in a proportionate increase (decrease) in the price per share and the per share information of the fund. Therefore, the splits did not change the aggregate net asset value of a shareholder’s investment at the time of the splits. For ZSL, VIXY, BOIL shareholders who hold a quantity of shares that is not an exact multiple of the Reverse Split ratio (i.e., not a multiple of 4 or 5), the Reverse Split will result in the creation of a fractional share. Post-Reverse Split fractional shares will be redeemed for cash and sent to the shareholder’s broker of record. This redemption may cause some shareholders to realize gains or losses, which could be a taxable event for those shareholders.

Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2023
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 December 31, 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.

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 year ended December 31, 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 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 December 31, 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 $ 109,410,342 $ 12,640,624 $ —  $ —  $ 122,050,966 ProShares Ultra Bloomberg Crude Oil 233,476,941 (3,515,232 ) —  17,954,935 247,916,644 ProShares Ultra Bloomberg Natural Gas 64,459,117 43,607,070 —  —  108,066,187 ProShares Ultra Euro —  —  306,949 —  306,949 ProShares Ultra Gold 59,507,594 4,096,275 —  3,078,593 66,682,462 ProShares Ultra Silver 114,276,025 12,400,748 —  (2,827,221 ) 123,849,552 ProShares Ultra VIX Short-Term Futures ETF —  (31,183,911 ) —  —  (31,183,911 ) ProShares Ultra Yen —  —  1,519,285 —  1,519,285 ProShares UltraShort Bloomberg Crude Oil 49,683,885 22,436,319 —  —  72,120,204 ProShares UltraShort Bloomberg Natural Gas —  (3,553,507 ) —  —  (3,553,507 ) ProShares UltraShort Euro —  —  (1,848,779 ) —  (1,848,779 ) ProShares UltraShort Gold —  (144,231 ) —  (199,821 ) (344,052 ) ProShares UltraShort Silver —  1,689,046 —  (814,174 ) 874,872 ProShares UltraShort Yen —  —  (1,311,925 ) —  (1,311,925 ) ProShares VIX Mid-Term —  (3,745,676 ) —  —  (3,745,676 ) ProShares VIX Short-Term Futures ETF 59,660,373 (9,664,094 ) —  —  49,996,279 Combined Trust: $ 690,474,277 $ 45,063,431 $ (1,334,470 ) $ 17,192,312 $ 751,395,550 * Includes cumulative appreciation (depreciation) of futures contracts as reported in the Schedule of Investments.

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 generally recognized on an accrual basis and includes the amortization of discount on short-term U.S. government and agency obligations and is reflected in the Statement of Operations. Additionally, interest income may be earned on cash held on deposit with brokers for futures contracts.
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
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., last three years 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

[1]The operations include the activity of ProShares Short Euro ETF and ProShares UltraShort Australian Dollar ETF through May 12, 2022, the date of liquidation.[2]Adjustments were made to the Statements by the Sponsor to reclassify amounts in Segregated cash balances with brokers for futures contracts with Receivable on open futures contracts and Payable on open futures contracts to reflect the temporary timing of account balances more accurately. These adjustments were not significant to the Fund in that they did not affect Shareholder’s equity or Net asset value per share.
