Key Takeaways
- • Record transaction volumes in 2025: Global private market secondaries closed at $220-$233 billion in 2025, representing a 40-42% year-over-year increase and marking an all-time high for the market.
- • 2026 projected to exceed $250 billion: According to William Blair's 2026 Secondary Market Report, transaction volumes are expected to reach approximately $250 billion in 2026, continuing the trajectory of record-breaking growth.
- • IPO slowdown driving liquidity demand: The ongoing contraction in initial public offerings has created sustained exit pressures for limited partners, directly fueling increased secondary market activity and transaction volumes.
- • Structural evolution, not cyclical event: Market participants characterize the secondary market expansion as a fundamental infrastructure shift in private capital management rather than a temporary liquidity event, underpinned by enduring structural demand drivers that have developed over two decades.
- • Strategic portfolio management tool: Secondaries have become an established mechanism enabling private markets to broaden participation and absorb capital flows without shortening investment horizons or increasing portfolio liquidity by design.
Summary
The private market secondaries landscape is entering a new growth phase, with 2025 marking a record-breaking year that establishes a foundation for continued expansion. Global transaction volumes reached between $220 billion and $233 billion in 2025, representing increases of 40-42% compared to 2024 levels. William Blair's 2026 Secondary Market Report projects that this momentum will persist, with volumes expected to surpass $250 billion in the coming year, indicating that market participants anticipate sustained structural demand rather than cyclical momentum.
The primary driver of this accelerating activity is the prolonged slowdown in initial public offerings, which has constrained traditional exit pathways for limited partners holding positions in private companies. As IPO windows have remained constrained, institutional investors have increasingly turned to secondary transactions as a mechanism to achieve liquidity objectives, rebalance portfolios, and manage their exposure to maturing private assets. This has created a pronounced need for intermediaries and secondary specialists to facilitate transactions between sellers seeking exit opportunities and buyers seeking access to established private market positions.
Industry observers emphasize that the secondary market expansion represents more than a temporary surge in exit activity—it constitutes a structural evolution in how private capital markets operate. Over the past two decades, secondaries have transitioned from an opportunistic trading mechanism to an integral component of institutional portfolio management strategy. This transformation has enabled private markets to attract broader participation without inherently shortening investment horizons or forcing changes to fundamental investment philosophies. The market's ability to absorb significant capital flows while maintaining the long-term orientation of private investing suggests that secondaries are now functioning as essential infrastructure within the broader alternative asset ecosystem.
As liquidity pressures persist and institutional investors continue seeking portfolio flexibility, secondaries are positioned to capture increasing capital flows driven by converging structural trends. The convergence of elevated private asset valuations, constrained exit alternatives, and growing institutional appetite for secondaries creates conditions supporting the projected acceleration toward $250 billion in 2026 volumes.
