The VC Secondary Market Boom: What It Means for Founders and Investors

The venture capital secondary market is having its moment. In 2025, secondary transaction volume hit $152 billion globally — more than double the volume from just three years prior. What was once a niche corner of private markets, associated with distressed sellers and discounted prices, has evolved into sophisticated, essential infrastructure for the entire venture ecosystem. For founders, investors, and LPs, understanding secondaries is no longer optional.

Why the Secondary Market Is Exploding

Three structural forces are driving the secondary boom. First, the IPO window has narrowed dramatically. The median time from Series A to IPO has stretched from 6 years in 2015 to over 10 years in 2025. Employees and early investors sitting on paper gains for a decade need liquidity, and secondaries provide it. Second, the 2021-2022 vintage of venture funds deployed record capital at elevated valuations. Many of those investments are now underwater, and LPs seeking to rebalance their portfolios are selling fund positions at discounts of 10-30%. Third, a new generation of secondary buyers — from dedicated funds like Lexington Partners and Industry Ventures to platforms like Forge and EquityZen — have built the infrastructure to make these transactions fast, compliant, and accessible.

What This Means for Founders

For founders, the secondary market is a double-edged sword. On the positive side, it provides liquidity options that didn't exist a decade ago. Founders can now sell a portion of their equity in structured secondary transactions, typically 10-20% of their holdings, during growth rounds. This allows them to take some chips off the table without a full exit, reducing personal financial pressure and enabling them to make longer-term decisions for the company. Many top VCs now actively encourage founder secondaries as a retention and alignment tool.

The downside: secondary transactions can introduce unknown shareholders onto your cap table. If an early employee sells their shares to a secondary fund, you might end up with a passive, purely financial investor who has no relationship with the company. Many savvy founders now include Right of First Refusal (ROFR) provisions in their equity documents, giving the company or existing investors the right to match any secondary offer. Some are going further, creating structured liquidity programs that let employees sell shares at predetermined windows and valuations, maintaining cap table control while providing genuine liquidity.

The LP Perspective: Portfolio Rebalancing at Scale

For LPs, secondaries have become a critical portfolio management tool. An endowment that committed $50M to venture in 2021 at peak valuations can now sell that fund position at a 15-25% discount, take the realized loss, and redeploy into current vintage funds at more attractive entry points. The math often works: selling a 2021 vintage fund at 0.75x NAV and redeploying into a 2026 vintage fund that benefits from lower entry valuations can generate higher risk-adjusted returns than holding the original position to maturity. Sophisticated LPs are increasingly treating secondaries as an active portfolio management strategy, not a last resort.

For emerging managers, the secondary boom creates both opportunity and competition. On the opportunity side, secondary funds are potential LPs — they understand venture economics deeply and can be excellent anchor investors. Some emerging managers are also incorporating secondary strategies into their primary funds, opportunistically purchasing positions in breakout companies at discounts. On the competition side, secondary buyers are increasingly competing for the same deals as primary investors, particularly in late-stage and growth rounds where secondary shares are readily available at discounts to the last round price.

The secondary market's maturation is a net positive for the venture ecosystem. It provides the liquidity that a 10+ year asset class desperately needs, enables better portfolio management for LPs, and gives founders and employees options they didn't have before. As the market continues to grow and infrastructure improves, we expect secondaries to become as routine as primary fundraising within the next five years.
