Global infrastructure fundraising reached unprecedented levels in 2025, as institutional investors concentrated capital into large, scaled platforms aligned with decarbonization, digitalization, and essential-service infrastructure. The year’s biggest fundraises highlight a clear preference for managers with the balance sheets, sourcing reach, and execution capacity to deploy quickly into power generation, grid modernization, and data-driven assets.

Leading the field, Global Infrastructure Partners closed Fund V at approximately $25.2 billion, according to firm disclosures, positioning the vehicle as one of the largest infrastructure funds ever raised. The flagship strategy spans transportation, energy transition, and digital infrastructure, reflecting where LP demand has been most durable.

Digital infrastructure emerged as another major beneficiary. Blue Owl Capital raised $7 billion for Digital Infrastructure Fund III, far exceeding its original $4 billion target, driven by strong investor appetite for data centers, fiber networks, and related assets tied to AI and cloud computing, the firm said.

Secondaries also played a growing role. Blackstone closed Strategic Partners Infrastructure IV at $5.5 billion, the largest dedicated infrastructure secondaries fund to date, focused on acquiring interests in existing infrastructure funds and portfolios.

Other notable closes included Morgan Stanley’s North Haven Infrastructure Partners IV, which raised $4.1 billion for a global core and core-plus strategy, and Brookfield Asset Management’s Infrastructure Debt Fund IV, which secured a first close above $4 billion for a global private credit strategy spanning senior and junior debt across core and transition assets.

Across these and similar vehicles, estimates from Preqin and industry participants suggest $200 billion to $289 billion was raised globally for unlisted, closed-end infrastructure funds in 2025, with a disproportionate share flowing to a small group of mega-managers aligned with energy transition and grid modernization themes.

Looking into 2026, most flagship platforms remain in market rather than newly closed, but early LP commentary suggests these same managers will continue to dominate allocations as they deploy record levels of dry powder. Investors are increasingly prioritizing real assets that combine resilient income, downside protection, and structural growth—driving a tilt toward infrastructure and private credit over traditional equity real estate.

That shift is particularly evident in debt strategies. Preqin data show real estate debt fundraising surged in 2025 and remains elevated into 2026, with more than 400 debt funds targeting over $100 billion, as higher base rates and wider spreads improve risk-adjusted returns.

At the portfolio level, large LPs are increasingly managing real estate and infrastructure within unified “real assets” buckets, reflecting overlapping asset types—from data centers to healthcare facilities—and similar income profiles. The result is intensifying competition among managers, where sector specialization, asset-level data, and execution capability matter more than broad asset-class labels alone.

Allocations are also becoming more globally diversified, with improving fundamentals and leverage dynamics in Europe and rising interest in under-owned Asian markets. As product structures evolve and technology lowers access barriers, managers expect a greater role for retail and high-net-worth investors in real assets, broadening the fundraising base beyond traditional institutional LPs.
