Secondary investments are purchases of existing stakes in private funds or other illiquid assets, bought from an investor who already holds the position rather than committed directly to a new fund. The global secondary market reached roughly $240 billion in transaction volume in 2025, making it one of the fastest-growing corners of private markets. Buyers use secondaries to enter funds that have already built portfolios, often at a discount to reported value. Sellers use them to get cash out of commitments that would otherwise lock up capital for a decade or longer.
How the Transaction Works
In a standard primary investment, you commit capital to a fund manager who deploys it over time into companies, properties, or other assets. A secondary investment skips that step. You buy an existing investor’s position and step into their rights and obligations mid-stream. The seller gets cash now. You get their claim on future distributions and the duty to meet any remaining capital calls.
The transfer runs through a legal document called an Assignment and Assumption Agreement, which formally moves the seller’s interest to you. The fund manager reviews the incoming buyer, and the fund administrator updates the partner register to reflect the new owner. From that point forward, capital calls come to you, and distributions flow to you as the fund exits its underlying investments.
Because you’re entering a fund that has already deployed capital, you gain something primary investors don’t have: visibility. You can evaluate actual portfolio companies and real performance data instead of trusting a pitch deck and a track record. That information advantage is one of the main reasons buyers accept the complexity of these transactions.
Why Buyers Want Them
The most frequently cited benefit is a reduced J-curve. In a primary fund, the early years hurt. You pay capital calls, management fees, and organizational expenses with no meaningful distributions coming back, and returns typically dip negative before climbing. Buying a secondary interest in a more mature fund means the portfolio has already absorbed those upfront costs and may be approaching the stage where exits generate cash. Distributions can begin much sooner than they would with a new commitment.
Buyers also face less blind pool risk. Primary investors commit before the manager has identified most of the deals they’ll make. Secondary buyers can see what’s already in the portfolio, often with 40% to 60% of the fund already invested.
Pricing is another draw. Secondary interests frequently trade at a discount to the fund’s reported net asset value, which means you acquire assets for less than their appraised worth. The discount size fluctuates with market conditions, but it creates an embedded gain on day one if the valuations hold. A single secondary purchase can also provide diversification across vintages, geographies, strategies, and managers that would take years to build through primary commitments alone.
Why Sellers Use Them
Sellers aren’t necessarily unhappy with their investments. The most common reason limited partners sell is portfolio rebalancing. A pension fund with a 10% target allocation to private equity might find itself at 15% after public market declines shrink the rest of the portfolio. Selling secondary interests brings the allocation back in line without waiting years for the fund to wind down.
Regulatory changes can also force sales. A bank subject to new capital requirements might need to reduce exposure to illiquid assets. Institutional investors facing unexpected liquidity needs, whether from beneficiary withdrawals or operational demands, sometimes sell at a discount simply because they need cash faster than the fund’s timeline allows. Others sell to exit a relationship with a particular manager or to consolidate their private markets portfolio around fewer, higher-conviction positions.
LP-Led and GP-Led Deals
The traditional secondary is LP-led. A limited partner decides to sell their stake, finds a buyer (often through a broker), negotiates a price, and transfers the interest. The fund manager isn’t driving the process but must approve the transfer. These deals can involve a single fund interest or a portfolio of stakes across many funds, which is common when a large institution wants to exit an entire program at once.
GP-led secondaries have grown dramatically and now represent a significant share of the market. Here the manager initiates the transaction. The most common structure is a continuation vehicle: the GP moves one or more high-performing assets from the existing fund into a new fund, often because the original fund is nearing the end of its term but the GP believes more value can be created with additional time.
Existing limited partners typically get three choices: cash out at the transaction price, roll their interest into the new vehicle on the same economic terms, or sometimes reinvest under new terms alongside incoming investors. A secondary buyer provides the capital that funds the cash-out option. The conflict of interest is obvious. The GP is effectively on both sides of the table, which is why independent valuations and LP advisory committee oversight are standard features of well-run continuation vehicle processes.
What Actually Trades
Private equity buyout and growth equity funds make up the largest share of the secondary market. Buyers step into those positions mid-fund-life, often after portfolio companies have been held for several years and have meaningful operating data.
Venture capital interests also trade actively, though they’re harder to value because many underlying companies haven’t generated revenue yet and the range of outcomes is extreme. Buyers typically apply steeper discounts to account for that uncertainty.
Real estate funds, including private REITs and closed-end property vehicles, provide another active market. Buyers acquire interests in funds that already own buildings, development projects, or land, skipping the initial acquisition and construction phases. Infrastructure funds holding positions in utilities, transportation networks, and energy assets trade similarly, attracting buyers who want exposure to stable, long-duration cash flows without waiting through a fund’s initial deployment period.
How Pricing Works
Every secondary trade starts with the fund’s most recent net asset value, which is the appraised worth of the underlying holdings. The buyer and seller then negotiate a price expressed as a percentage of NAV. A price of 90% of NAV is a 10% discount. A price of 105% is a 5% premium.
Discounts are the historical norm because the buyer takes on real risks: the NAV may be stale by several months, the assets are illiquid, and the buyer has less information than someone who’s been in the fund from the start. Premiums do occur, especially for interests in top-performing funds managed by brand-name GPs where buyer demand exceeds supply. Market conditions move pricing meaningfully. During periods of distress, discounts can widen to 20% or more. In strong markets, high-quality buyout interests sometimes trade above par.
Beyond the headline price, buyers evaluate several other factors: how much unfunded commitment remains (which determines future capital calls), the fund’s remaining term, the concentration of the underlying portfolio, the quality of the GP, and the fund’s distribution pace relative to its age. The most recent audited financial statements and quarterly reports are the primary evidence for these assessments.
A secondary purchase isn’t a quick transaction. The full process from initial bid to closing generally takes 60 to 90 days, covering due diligence, price negotiation, GP consent, any right of first refusal, and the legal mechanics of the transfer documents.
Who’s Allowed to Buy
Secondary investments in private funds are not open to the general public. Because these funds rely on exemptions from registration under the Investment Company Act, buyers must meet specific financial qualification thresholds.
Funds structured under Section 3(c)(1) of the Investment Company Act may have no more than 100 beneficial owners, all of whom must be accredited investors. To qualify as an accredited investor, an individual needs either a net worth above $1 million (excluding a primary residence) or annual income above $200,000 individually or $300,000 jointly with a spouse for each of the prior two years, with a reasonable expectation of the same going forward.1U.S. Securities and Exchange Commission. Accredited Investors
Funds structured under Section 3(c)(7) can have up to 2,000 beneficial owners, but every investor must be a qualified purchaser, a higher bar. For individuals, that means owning at least $5 million in investments.2Cornell Law Institute. Definition: Qualified Purchaser From 15 USC 80a-2(a)(51) For institutional investors, the threshold is $25 million. Most large secondary funds use the 3(c)(7) structure because it allows more investors, but the qualification requirement is considerably steeper.
You also can’t simply sell a limited partnership interest the way you’d sell a stock. The fund’s partnership agreement governs every transfer and almost always requires the GP’s written consent. Many agreements also include a right of first refusal, giving existing partners or the fund itself the right to match an outside buyer’s offer. When triggered, the ROFR holder typically has 30 to 60 days to decide.
Tax Treatment to Know
Selling a secondary interest is treated as the sale of a partnership interest for federal tax purposes, and the consequences are more complex than selling publicly traded securities.
If you’ve held the interest for more than one year, gain is generally taxed at long-term capital gains rates. High earners also face an additional 3.8% net investment income tax on top of those rates.
Here’s where sellers get tripped up. If the fund holds what the IRS calls “hot assets,” which are unrealized receivables and inventory items, the portion of your gain attributable to those assets is taxed as ordinary income regardless of how long you held the interest.3Office of the Law Revision Counsel. 26 US Code 751 – Unrealized Receivables and Inventory Items That can mean a federal rate as high as 37% on that portion instead of the 20% capital gains rate you expected. Depreciation recapture on equipment or real estate within the fund’s portfolio is a common trigger.
For buyers, the most important tax concept is the Section 754 election. When a partnership has this election in place, buying a secondary interest triggers a basis adjustment under Section 743(b) that aligns your tax basis in the underlying assets with what you actually paid.4Office of the Law Revision Counsel. 26 US Code 754 – Manner of Electing Optional Adjustment to Basis of Partnership Property Without it, you could end up paying tax on gains that economically belong to the previous owner, because the fund’s internal basis in its assets won’t match your purchase price.
The adjustment works in your favor when you buy at a discount: paying less than the seller’s share of the partnership’s asset basis gives you an increased basis that generates higher depreciation deductions and lower taxable gains when the fund sells assets. You must notify the partnership in writing within 30 days of the purchase, and the partnership attaches the computation to its tax return for that year.5eCFR. 26 CFR 1.743-1 – Optional Adjustment to Basis of Partnership Property If the fund doesn’t have a 754 election in place, ask whether the GP will make one. Some will. Some won’t. Confirm it before you close.
Risks Before You Buy
The information gap is the biggest risk most buyers underestimate. You’re entering a fund relationship mid-stream, and no matter how thorough your due diligence, the GP and existing LPs will always know more than you do about the portfolio’s history, the manager’s patterns, and the nuances of specific investments. Quarterly reports tell you what happened. They don’t always explain why, or what’s coming next.
Valuation risk compounds the information problem. The NAV used to price the deal may be three to six months old by the time you close. Private asset valuations are inherently lagged and subjective, and reported NAV can diverge meaningfully from what the assets would actually fetch in a sale. Buying at what looks like a 10% discount provides no protection if the underlying assets are overvalued by 15%.
Illiquidity doesn’t end when you buy a secondary. You’ve simply become the new holder of an illiquid position. If you need to exit before the fund winds down, you’ll face the same market you just bought from, and conditions may be less favorable. Capital call risk is a related concern: the fund’s remaining unfunded commitments become your obligation, and calls can arrive on short notice at inconvenient times.
GP-led transactions carry a specific conflict-of-interest risk. When the manager is structuring the deal, setting the price, and selecting the secondary buyer, existing LPs need to scrutinize whether the process genuinely serves their interests or primarily serves the GP’s desire to keep managing assets and earning fees. Independent valuations and active LP advisory committees reduce this risk, but the tension is structural.
Core Due Diligence Documents
Thorough due diligence is what separates profitable secondary purchases from expensive mistakes. The core documents to review include:
- Limited partnership agreement: the governing document that defines transfer restrictions, capital call procedures, fee structures, distribution waterfalls, and GP removal rights. Every other document is subordinate to this one.
- Financial statements: audited annual reports and unaudited quarterly updates covering at least the most recent three to five years. Look at valuation methodology, write-downs, and how marks compare to eventual exit prices.
- Capital call and distribution history: the full record of when capital was called and returned. This reveals the fund’s pacing, how much dry powder remains, and whether distributions are accelerating or slowing.
- Side letters: agreements between the GP and specific LPs that may grant preferential terms on fees, co-investment rights, or information access. The seller’s side letter rights may or may not transfer with the interest.
- Portfolio company details: current operating data, recent valuations, and exit timelines for each significant holding. A concentrated portfolio with two or three dominant positions carries different risk than a diversified one.
The seller’s motivation matters as much as the documents. A seller dumping a position at a steep discount because they’ve lost confidence in the GP tells you something different than a pension fund selling at a modest discount to rebalance. Both are legitimate transactions, but they carry different signals about what you’re buying into.
