A hedge fund, a private equity fund and a venture capital fund are all private pools of money run by professional managers. They differ in what they buy, how long investors' money stays in, how the manager is paid and how the holdings are priced.
One table sets the three side by side. The rules and figures are US ones, taken from the definitions and statistics of the US Securities and Exchange Commission (SEC) for the end of 2025. Form PF is the report that SEC-registered private fund advisers with at least $150 million in private fund assets file about their funds, wherever those funds are based.
What is the difference between a hedge fund, private equity and venture capital? A hedge fund trades investments, can bet against prices and lets investors withdraw at set dates. Private equity and venture capital funds buy private companies, call money from investors over several years and return it as they sell.
Private equity and other illiquid funds, such as venture capital funds, typically show a J-curve: negative returns in the early years, positive ones later. A private equity fund typically charges its fee on money committed, including money not yet invested.
Listed shares have quoted prices, so a hedge fund can value many holdings at market prices. A private company has none, so a private equity or venture capital fund estimates its value until it sells.
At the end of 2025, hedge funds reporting to the SEC on Form PF held $2.41 of gross assets for every $1 of net assets, against $1.10 for private equity and $1.04 for venture capital.

Each row states what is true of the type as the SEC defines or describes it, not of one firm. All three are private funds: pooled money sold privately, not to the general public. Our guide to what a hedge fund is covers the first type in full.
What each fund buys
A hedge fund buys whatever its strategy needs: shares, bonds, currencies, futures and other contracts. It can sell short, which means betting that a price will fall. It can also borrow to buy more. Long/short equity and multi-manager hedge funds are two strategies.
A private equity fund buys stakes in companies that are not listed on an exchange. A typical strategy, the SEC says, is to take a controlling interest and help manage the company. Other funds take minority stakes in fast-growing companies.
A venture capital fund buys equity in start-up and early-stage companies. Under the SEC's definition, no more than 20% of its capital may sit in assets other than equity bought directly from private companies, not counting cash and similar holdings.
Lock-ups and liquidity
Liquidity is how quickly investors can get their money out. Hedge funds typically allow withdrawals four times a year or fewer, according to the SEC. They often add a lock-up, a period of a year or more when money cannot be withdrawn.
Private equity and venture capital funds offer little or no right to withdraw. Money comes back as the fund sells its holdings, over an investment time horizon the SEC puts at typically 10 or more years for private equity. The SEC's venture capital definition allows no withdrawal rights except in extraordinary circumstances.
Money goes in differently too. A hedge fund investor generally decides when and how much to invest. A private equity or venture capital investor commits a sum, then pays it in when the manager makes a capital call, a request for money to fund an investment.
How each is paid
A hedge fund charges a management fee of 1% to 2% of net asset value, which is what the fund owns less what it owes. It also charges a performance fee of 15% to 20% of profit, according to the SEC. A high-water mark can limit when that fee is due. How hedge fund fees work has the arithmetic.
Private equity and venture capital managers are paid a management fee plus carried interest, a share of the fund's profits. The SEC's examination staff says private equity funds typically charge the fee on investors' capital commitments while the fund is investing. It later falls back to invested capital, less sales and write-offs.
So the fee base includes money that is committed but not yet invested.
The J-curve
The J-curve is the shape of a private fund's cash flows and returns over its life: negative at first, positive later. The chart below plots the cash. The SEC says it arises as capital calls occur, funds deploy capital and hold unrealised investments, then reverses as investments are exited and proceeds distributed.
The illustration assumes an investor commits $100 million. The fund charges 2% of the commitment, $2 million, in each of 10 years. Holding the fee on commitments for the whole life keeps the arithmetic simple, so it is a simplification of the falling fee base described above. It buys four companies for $20 million each at the start of years 1 to 4, holds each for five years and sells at twice the cost. Carried interest is left out.

Source: YX Insights illustration, assumed figures
The chart tracks net cash, the money the investor has received less the money paid in. It falls to −$88 million in year 4 and turns positive in year 7. Cash below zero means money is still out, which is not the same as a loss. By year 10 the investor has paid in $100 million and received $160 million. The figures are assumed, not a forecast.
Mark-to-market and mark-to-model
Mark-to-market means valuing a holding at the price it trades for. Mark-to-model means valuing it by estimate, because no price is available.
Form PF asks funds to sort their assets into three levels. Level 1 assets have quoted prices in active markets for identical assets. Level 3 assets are valued from the fund's own assumptions. Level 2 sits between them, using inputs that can be observed other than quoted prices.
Listed shares can sit in Level 1. A private company has no quoted price. The SEC points to the difficulty of valuing unrealised investments in illiquid funds. The SEC's investor site adds that hedge funds may also hold investments that are difficult to value.
How much each borrows
Gross assets are everything a fund owns before subtracting debt and other liabilities. Net assets are what remains. The gap between them is the debt and other liabilities.

The chart uses the SEC's Form PF statistics. At the end of 2025, hedge funds reported $2.41 of gross assets for each $1 of net assets, private equity funds $1.10 and venture capital funds $1.04.
Form PF has a fund that invests through another fund include that holding in its own assets, so some assets sit in more than one total.
Form PF counts a private fund as a hedge fund if it meets any one of three tests. The first is a performance fee on unrealised gains. The second is the ability to borrow more than half its net assets, or to run derivatives exposure of more than twice them. The third is the ability to sell short. The SEC's venture capital definition caps borrowing at 15% of capital, for no more than 120 days.
Who can invest
In the US, an individual is an accredited investor with a net worth over $1 million, not counting the main home. Income over $200,000 in each of the past two years also qualifies, or $300,000 with a spouse or partner, as do some licence holders.
Some funds require the higher qualified purchaser test, which means at least $5 million in investments.
At the end of 2025, US individuals held 9.4% of the net asset value of all private funds in Form PF. State and municipal government pension plans held 12.0%. All three fund types are in that total.
Our hedge fund guide also sets out the UK rules.
The three types differ in what they hold, how money enters and leaves, how the manager is paid and how value is set. The table sets out those differences row by row.

Common questions about hedge funds, private equity and venture capital
What is the main difference between a hedge fund and private equity?
A hedge fund trades investments and lets investors withdraw at set dates, typically four times a year or fewer. A private equity fund buys stakes in private companies, calls investors' money over several years and returns it as holdings are sold. Its term is typically 10 or more years.
What is the difference between private equity and venture capital?
Both buy private companies. Private equity funds often take a controlling interest in an operating company, while venture capital funds buy equity in start-up and early-stage companies. Under the SEC's definition, a venture capital fund holds no more than 20% of its capital in other assets.
What is the J-curve in private equity?
The J-curve is the typical shape of an illiquid fund's cash flows and returns: negative in the early years as capital is called and invested, then positive as investments are sold. In this guide's assumed example, cumulative net cash falls to −$88 million in year 4 and turns positive in year 7.
Can anyone invest in a hedge fund, private equity or venture capital?
No. In the US, investors are usually accredited, with a net worth over $1 million excluding the main home, or income over $200,000 in each of the past two years. Some funds require qualified purchaser status, which means at least $5 million in investments.
What does mark-to-model mean?
Mark-to-model means valuing a holding by estimate because no quoted price exists. On Form PF, funds sort assets into three levels. Level 1 uses quoted prices, Level 3 uses the fund's own assumptions and Level 2 uses other observable inputs.
