Prospectus [Line Items]  
Risk [Text Block] Principal Risks
Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Derivatives Risk — Investing in derivatives to obtain exposure may be considered aggressive and may expose the Fund to greater risks including counterparty risk and correlation risk. The Fund may lose money if its derivatives do not perform as expected and may even lose money if they do perform as expected. To the extent the Fund invests in swaps that use an ETF as the reference asset, the Fund will be subject to the risks of that ETF including the risk that the ETF may not meet its investment objective. In addition, the Fund may be subject to greater correlation risk since the performance of the ETF may not correlate to the performance of the Index. Any costs associated with using derivatives will reduce the Fund’s return.
Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Counterparty Risk — The Fund may lose money if a counterparty does not meet its contractual obligations. With respect to swap agreements, the terms of the agreement between the Fund and its counterparty may permit the counterparty to immediately close out the transaction with the Fund, including intraday (for example, if the Index has a dramatic intraday move that causes a material decline in the Fund’s net assets). If an agreement is terminated, the Fund may be unable to enter into another swap agreement or invest in other derivatives to achieve its investment objective.
Small-Mid Cap Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Small-Cap Company Investment Risk — The risk of equity investing may be particularly acute for securities of issuers with smaller market capitalizations. Small-cap companies may have limited product lines or resources, may be dependent upon a particular market niche and may have greater fluctuations in price than the stocks of larger companies. Small-cap companies may lack the financial and personnel resources to handle economic or industry-wide setbacks and, as a result, such setbacks could have a greater effect on small-cap security prices. Additionally, small-cap company stocks may trade at greater spreads or lower trading volumes, and may be less liquid than the stocks of larger companies. Further, stocks of small-sized companies could be more difficult to liquidate during market downturns compared to larger, more widely traded companies.
Equity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Equity and Market Risk — Equity markets are volatile, and the value of equity securities and other instruments correlated with equity markets may fluctuate dramatically from day to day. Equity markets are subject to corporate, political, regulatory, market, social, geopolitical and economic developments, including changes in interest and currency rates, inflation (or expectations for inflation), deflation (or expectations for deflation), global demand for particular products or resources, market instability, debt crises, embargoes, tariffs, sanctions and other trade barriers, regulatory or governmental trade or market control programs, recessions, supply chain disruptions, labor disturbances, environmental or man-made disasters, war, terrorism, public health emergencies (such as the spread of infectious diseases, pandemics and epidemics), social unrest and other unforeseeable events.
Money Market Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Money Market Instruments Risk — Adverse economic, political or market events affecting issuers of money market instruments, defaults by counterparties or changes in government regulations may have a negative impact on the performance of the Fund.
Correlation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Correlation Risk — A number of factors may affect the Fund’s ability to achieve a high degree of correlation with the Index. Fees, expenses, transaction costs, among other factors, will adversely impact the Fund’s ability to meet its investment objective. In addition, the Fund’s exposure may not be consistent with the Index. For example, the Fund may not have exposure to all of the securities in the Index, its weighting of securities may be different from that of the Index, and it may invest in instruments not included in the Index.
Concentration-Focus Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Industry Concentration Risk — The Index may have a significant portion of its value in issuers in an industry or group of industries. The Fund will allocate its investments to approximately the same extent as the Index. As a result, the Fund may be subject to greater market fluctuations than a fund that is more broadly invested across industries. As of December 31, 2025, the Index had a significant portion of its value in issuers in the financials, health care and industrials industry groups.
Financials Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ○Financials Industry Risk — Companies in this industry may experience: extensive governmental regulation and/or nationalization that affects the scope of their activities, the prices they can charge and the amount of capital they must maintain; adverse effects from increases in interest rates; adverse effects on profitability by loan losses; and severe competition.
Health Care Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ○Health Care Industry Risk — Companies in this industry may experience: heavy dependence on patent protection; litigation and product liability expense; the long and costly process for obtaining new product approval by the Food and Drug Administration; and product obsolescence.
Industrials Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ○Industrials Industry Risk — Companies in this industry may experience: adverse effects on stock prices by supply and demand both for their specific product or service and for industrials industry products in general; declining demand; and changing government regulation.
Index Performance Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Index Performance Risk — The Index used by the Fund may underperform other asset classes and may underperform other similar indices. The Index is maintained by a third party provider unaffiliated with the Fund or ProFund Advisors. There can be no guarantee that the methodology underlying the Index or the daily calculation of the Index will be free from error.
Active Investor Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Active Investor Risk —The Fund permits short-term trading of its securities. This may have a negative impact on the Fund’s ability to achieve its investment objective or maintain a consistent level of operating expenses. In certain circumstances, the Fund’s expense ratio may vary from current estimates or the historical ratio disclosed in this Prospectus. In addition, this will increase portfolio turnover and may result in additional costs for the Fund.
Early Close Late Close Trading Halt Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Early Close/Late Close/Trading Halt Risk — An exchange or market may close early, close late or issue trading halts on specific securities or financial instruments. In these circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.
Risk Lose Money [Member]  
Prospectus [Line Items]  
Risk [Text Block] You could lose money by investing in the Fund.
Risk Nondiversified Status [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Non-Diversification Risk — The Fund has the ability to invest a relatively high percentage of its assets in the securities of a small number of issuers or in financial instruments with a single counterparty or a few counterparties. This may increase the Fund’s volatility and increase the risk that the Fund’s performance will decline based on the performance of a single issuer or the credit of a single counterparty.
