Adams Street Partners, a leading private markets investment management firm with more than $65 billion in assets under management, has announced the successful final close of its sixth co-investment fund, Adams Street Co-Investment Fund VI, with $2.5 billion in committed capital — exceeding its original target. The close, announced on April 22, 2026, attracted strong demand from a globally diversified investor base, underscoring continued institutional interest in co-investment strategies despite a more challenging fundraising environment. Following the Fund VI close, Adams Street now manages $7.2 billion in co-investment strategy assets.
Fund VI builds on Adams Street’s longstanding co-investment platform, which has historically sought to provide diversified exposure to investments alongside high-quality managers across sectors, geographies, and market cycles. The oversubscribed demand reflects what Adams Street describes as investors’ continued pursuit of enhanced selectivity, efficient access to private equity opportunities, and the ability to deploy capital alongside trusted sponsors. Recent findings from Adams Street’s Global Investor Survey echo this trend, with investors citing the ability to enhance returns, reduce fee drag, and gain more direct exposure to high-conviction opportunities as key drivers behind increased allocations to co-investment strategies.
Dave Brett, Partner and Head of Co-Investments at Adams Street, described the close as a reflection of both the strength of the firm’s co-investment platform and the increasing role co-investments are playing in investor portfolios — noting that investors are prioritising strategies offering greater visibility, alignment, and cost efficiency. Jeffrey Diehl, Managing Partner and Head of Investments at Adams Street, underscored the significance of the close achieved in a more challenging fundraising environment, describing co-investments as a compelling solution in today’s market where access and selectivity are critical.
The close reinforces Adams Street’s position as one of the most established co-investment platforms globally, leveraging over 50 years of private markets experience, deep GP relationships, and a 100% employee-owned structure to source and execute opportunities alongside many of the world’s leading sponsors.
