Private Infrastructure Regained Momentum in 2025: AUM Reached USD 1.6 Trillion

The fifth annual Infrastructure Strategy 2026: Year of Increasing Scale and Diversification report from Boston Consulting Group (BCG) shows that the private infrastructure asset class is entering a strong recovery phase. The report demonstrates that assets under management (AUM) reached USD 1.6 trillion in the first half of 2025, representing 10% of all private market assets.

Fundraising Sets Records
Fundraising activities for private infrastructure in 2025 showed approximately 60% growth, setting a new record. The report emphasizes that this recovery is stronger compared to other private asset classes. Approximately three-quarters of raised capital was directed to the largest 50 infrastructure funds, with nearly half going to the top five funds.

Digital Infrastructure Grows
Digital infrastructure stands out as the only major sector showing significant growth over the past five years. It now represents approximately 20% of all portfolio companies; this figure was 15% in 2020. Data centers accounted for 41% of digital transactions, rising substantially from 26% in 2024.

Wilhelm Schmundt, BCG co-author, stated, "Private infrastructure has regained scale, but the market structure is changing. Investors continue to direct capital to the largest managers in pursuit of stable and reliable returns."

Shifts in Energy and Environment Investments
The number of transactions in energy and environment rose from 176 to 207 in 2025. However, the sector composition changed significantly: processing and distribution transactions represented 50% of the total, while renewable energy transactions declined from 42% to 22%.

Co-author Alex Wright stated, "A clear trend in 2025 is that digital infrastructure is becoming increasingly inseparable from energy strategy. Power availability, grid connectivity and integrated energy solutions are at the center of how investors evaluate data centers."
