HarbourVest Raises $865M for Third Infrastructure Fund - InforCapital

HarbourVest Partners has announced the final close of Infrastructure Opportunities Fund III (IOF III) at 865 million USD, more than double the size of its predecessor. The fund has been active since December 2023, deploying capital alongside leading general partners to give investors exposure to hard-to-access segments and resilient infrastructure assets.

IOF III will primarily focus on secondary opportunities, while also allocating to direct co-investments across infrastructure in North America and Western Europe. Notable backers include the Fresno County Employees’ Retirement Association, which committed 55 million USD earlier this year.

According to Michael Dean, Managing Director at HarbourVest Partners, infrastructure secondaries remain undercapitalized, and rising demand for liquidity positions the firm to deliver resilient performance while enhancing portfolio durability in today’s evolving market.

HarbourVest has been active in infrastructure since 2014, with secondaries forming a key component of its overall platform. Following strong deal flow in 2024, the firm expects 2025 to bring continued opportunities as limited partners seek liquidity and differentiated access to core and value-add infrastructure assets.

The HarbourVest close highlights growing interest in infrastructure secondaries, a segment that has expanded rapidly alongside traditional private equity secondaries. Comparable developments include:

• Ardian Infrastructure Fund V, which raised more than 6 billion USD, allocating a significant portion to secondary deals across European energy and transport assets.
• Brookfield Infrastructure Secondaries Program, which has pursued multi-billion transactions to provide liquidity to large LPs while targeting brownfield energy and utility assets.
• StepStone Infrastructure & Real Assets (SIRA) platform, which has steadily increased allocations to secondaries as institutional investors demand liquidity solutions.
• Blackstone Strategic Partners, which has raised dedicated secondaries pools with a growing focus on infrastructure, renewables, and digital assets such as data centers.

Infrastructure secondaries are benefiting from a convergence of trends: LP liquidity needs, increased capital intensity of energy transition projects, and the growing maturity of infrastructure as an institutional asset class. Investors are using secondaries both to rebalance portfolios and to access stable, cash-generating infrastructure assets at attractive entry points.

For HarbourVest, the success of IOF III confirms its role as a specialist player in this market niche, offering differentiated access and scale at a time when infrastructure secondaries remain undersupplied relative to demand.
