Private Infrastructure Asset Management Hits $1.6 Trillion Mark in 2025 as Fundraising Soars

The Rise of Private Infrastructure: A Record $1.6 Trillion AUM in 2025

In an impressive turnaround, the private infrastructure sector has witnessed a remarkable recovery, reaching an astonishing $1.6 trillion in assets under management (AUM) during the first half of 2025. This significant growth marks a strong comeback for the asset class, now accounting for 10% of all private market assets. The latest report by the Boston Consulting Group (BCG), titled "Infrastructure Strategy 2026: A Year of Increasing Scale and Diversification," reveals a nearly 60% rise in fundraising, establishing a new benchmark and outpacing other private asset categories.

Private infrastructure investments have traditionally been viewed as a stable option for investors, characterized by reliable returns. However, as noted by Wilhelm Schmundt, a coauthor of the BCG report, the landscape is evolving. Investor preferences are increasingly gravitating towards the largest and most diversified managers in the market. The report highlights that almost three-quarters of all capital raised in 2025 flowed to the top 50 infrastructure funds, with a striking half allocated to just the top five.

Shift Towards Digital Infrastructure

One of the most noteworthy developments in this resurgence is the growing significance of digital infrastructure, which now constitutes nearly 20% of portfolio companies compared to 15% in 2020. This trend is particularly evident in data center investments, which accounted for an impressive 41% of digital deals in 2025, reflecting an increase from 26% in the previous year.

The demand for data centers is reshaping investment strategies, with notable constraints arising from limited power availability and lengthy grid connection timelines. This has prompted a strategic shift, directing investments not just to major urban centers (Tier 1 locations) but also venturing into Tier 2 and Tier 3 markets, as well as exploring off-grid projects supported by dedicated power generation resources.

Evolving Energy Landscape

In terms of energy and environmental objectives, the landscape has become more complex. The number of deals in this sector saw a rise from 176 in 2024 to 207 in 2025. However, the nature of these deals has evolved significantly. Processing and distribution now represent 50% of all deals, escalating from approximately one-third the previous year. Simultaneously, the share of renewable energy projects has taken a hit, dropping to 22% from 42%. This decline is largely attributed to various pressures, including rising costs, fluctuating capture prices, and shifts in political and regulatory support across numerous countries.

As electricity demand soars, conventional energy and related infrastructure are gaining renewed interest due to grid bottlenecks and rising costs in traditional renewable projects.

Integrating Energy and Infrastructure Strategies

Alex Wright, another coauthor of the report, emphasizes that the interplay between digital infrastructure and energy strategies is set to become increasingly intertwined. Investors must now assess power availability, grid connectivity, and integrated energy solutions as critical factors when evaluating data center investments. The confluence of these trends signals a pivotal moment for private infrastructure strategies moving forward.

This transformative phase in private infrastructure not only highlights the resilience of the asset class but also underscores the necessity for investors to adapt to shifting market conditions focused on stability and reliable returns. As the investment landscape continues to evolve, stakeholders will need to remain agile and responsive to capitalize on emerging opportunities within this vibrant sector.
