Secondary transaction volumes in private markets reached $100 billion in the first half of 2025, a new half-year record that confirms the asset class has moved past experimental allocation into structural portfolio necessity. The figure represents a 47% increase over H1 2024 and marks the first time half-year volume has crossed the $100 billion threshold, driven primarily by accelerated exits from private credit LP positions and sponsor-led continuation vehicles in infrastructure debt.
The velocity caught data vendors and fund administrators unprepared. Secondary pricing remains opaque outside the 12-15 lead market-makers, settlement cycles average 90-120 days versus 45-60 days in comparable liquid credit, and reference data for underlying collateral remains fractured across custodians. Three tier-one allocators told counterparties in May they would pause secondary purchases until mark-to-market protocols standardized, a position reversed within 14 days after observing competitor activity. The gap between transaction demand and infrastructure capacity is no longer a future risk.
What matters is the composition shift. Private credit secondaries accounted for $38 billion of H1 volume, up from $19 billion in H1 2024, while traditional buyout fund secondaries grew just 11% over the same period. The credit surge reflects two forces: insurance balance sheets rotating out of direct lending stakes acquired in 2021-2022, and family offices seeking shorter duration exposure without primary commitment lock-ups. Continuation funds, where GPs transfer assets into new vehicles and offer LPs liquidity or rollover, contributed $22 billion in credit secondaries alone, nearly triple the year-ago figure.
Pricing discovery remains the choke point. Bid-ask spreads on credit secondaries widened to 320-480 basis points in Q2 versus 180-240 basis points for buyout secondaries, driven by valuation uncertainty on floating-rate direct loans written at peak SOFR spreads. Settlement delays compound the problem. Portfolio companies underlying secondary stakes often require consent for LP transfers, a process that stretches closing timelines and introduces counterparty risk buyers are pricing at 150-200 basis points above comparable liquid instruments. Data vendors have no standardized taxonomy for private credit collateral, forcing buyers to rebuild reference files deal-by-deal.
Allocators should monitor three developments through Q3. First, whether Blackstone, Ardian, and Goldman Sachs Secondary Opportunities complete their combined $18 billion in credit-focused secondary fundraises by September, which would formalize the buyer base and compress spreads. Second, whether ILPA's expected August guidance on secondary transfer protocols gains traction among fund administrators, potentially shortening settlement to 60 days. Third, whether pricing services adopt machine-readable loan-level data standards by year-end, reducing manual reconciliation that currently adds $40,000-$80,000 per secondary transaction in due diligence costs.
The $100 billion half-year mark is less a milestone than a revelation. Private credit secondaries are now a $75-80 billion annual run-rate market operating with pre-2015 infrastructure, creating arbitrage for those who build internal data capacity and accept settlement friction competitors won't.
