Subsequent Events [Abstract] |
Subsequent Events | NOTE 8 – SUBSEQUENT EVENTS On February 11, 2026, the Trust announced a 1-for-10 reverse split of the shares of beneficial interest of ProShares UltraShort Silver (ticker symbol: ZSL). The Reverse Split was effective prior to market open on February 26, 2026, when the Fund began trading at its post-Reverse Split price. The ticker symbol for the Fund did not change; however, the Fund was issued a new CUSIP number (74347Y672).The Reverse Split was applied retroactively for all periods presented, reducing the number of shares outstanding and resulting in a proportionate increase in the price per share and per share information of the Fund. Therefore, the Reverse Split did not change the aggregate net asset value of a shareholder’s investment at the time of the Reverse Split. For shareholders who hold a quantity of shares that is not an exact multiple of the Reverse Split ratio (i.e., not a multiple of 10), 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. Subsequent to the period end, certain Funds of ProShares Trust II (the “Trust”) began investing a portion of their available cash balances in the ProShares GENIUS Money Market ETF (“IQMM”), an exchange-traded fund sponsored and advised by ProShare Advisors LLC, the Sponsor of the Trust. IQMM commenced operations in February 2026.
