Secondary Market Volume Is Tracking Toward a $250 Billion Year

What Happened Alternatives Watch, citing William Blair's 2026 Secondary Market Report, said global secondary transaction volume reached $220 billion in 2025 , up 42% year over year. Survey respondents expect the market to rise further to roughly $250 billion in 2026, with some predicting the asset class could eventually approach $400 billion by the end of the decade. The numbers reflect persistent liquidity needs from LPs, continued sponsor use of GP-led structures, and a broader institutionalization of the market. Reading the Data Even without a fully normalized exit backdrop, secondaries continue to absorb a larger share of private market liquidity demand. That matters because larger market size tends to improve price discovery, deepen buyer specialization and reduce friction for both sellers and sponsors. 2025 volume: $220 billion 2026 projection: $250 billion Longer-term upside case: as much as $400 billion by decade end The market is no longer a side pocket of private equity; it is becoming a core liquidity layer for the broader private capital ecosystem. Why This Matters for Private Markets For Syndikos readers, the takeaway is straightforward: better scale supports better execution. As secondary volume expands, pricing references become more credible, capital becomes more segmented by strategy, and private market participants gain more options to rebalance, realize value and source exposure across cycles.
