Strategy Narrative [Text Block]	The Fund invests in financial instruments that ProFund Advisors believes, in combination, should track the performance of the Index.The Index is designed to measure the performance of value stocks included in the S&P MidCap 400 Index. The S&P MidCap 400 Index is designed to measure the performance of mid-cap companies listed and domiciled in the U.S. As of December 31, 2025, the market capitalization of companies in the Index was between $503 million and $21 billion. The Index includes the stocks in the S&P MidCap 400 Index with the strongest value characteristics based on: book value to price ratio, earnings to price ratio, and sales to price ratio. The selected stocks are then weighted based on market capitalization. The Index’s composition and assigned weights are reevaluated annually in December with additional weight adjustments in March, June and September. The Index is constructed and maintained by S&P Dow Jones Indices LLC. More information about the Index can be found using the Bloomberg ticker symbol “MIDV.” Under normal circumstances, the Fund will invest at least 80% of its total assets in components of the Index or in instruments with similar economic characteristics.The Fund will invest principally in the financial instruments listed below.●Equity Securities — Common stock issued by public companies.●Derivatives — Financial instruments whose value is derived from the value of an underlying asset or rate, such as stocks, bonds, exchange-traded funds, interest rates or indexes. The Fund invests in derivatives (e.g. swap agreements and futures contracts) in order to gain exposure to the Index. These derivatives principally include:○Swap Agreements — Contracts entered into primarily with major global financial institutions for a specified period ranging from a day to more than one year. In a standard swap transaction, two parties agree to exchange or “swap” payments based on the change in value of an underlying asset or benchmark. For example, two parties may agree to exchange the return (or differentials in rates of returns) earned or realized on a particular investment or instrument.○Futures Contracts — Standardized contracts that obligate the parties to buy or sell an asset at a predetermined price and date in the future.●Money Market Instruments — The Fund expects that any cash balances maintained in connection with its use of derivatives will typically be held in high quality, short-term money market instruments, for example:○U.S. Treasury Bills — U.S. government securities that have initial maturities of one year or less, and are supported by the full faith and credit of the U.S. government.○Repurchase Agreements — Contracts in which a seller of securities, usually U.S. government securities or other money market instruments, agrees to buy the securities back at a specified time and price.ProFund Advisors uses a mathematical approach to investing in which it determines the type, quantity and mix of investment positions that it believes, in combination, the Fund should hold to produce returns consistent with its investment objective. The Fund seeks to remain fully invested at all times in financial instruments that, in combination, provide exposure consistent with the investment objective, without regard to market conditions, trends or direction. The Fund may also invest in or gain exposure to only a representative sample of the securities in the Index or to securities not contained in the Index or in financial instruments, with the intent of obtaining exposure consistent with the investment objective.Please see “Investment Objectives, Principal Investment Strategies and Related Risks” in the Fund’s Prospectus for additional details.
