Preqin forecasts that global infrastructure fund assets under management will reach US$2.74 trillion by the end of 2031, growing 9.8% a year, and ranks infrastructure with private credit as the fastest-growing private market asset classes to 2031, a forecast that gives Asia-Pacific allocators a framework for questions about power, digital networks and supply chains but no regional infrastructure figure.

TL;DR

  • Preqin's Private Markets in 2031 report expects infrastructure fund AUM of US$2.74 trillion, a 9.8% annualised growth rate, within total private markets AUM above US$34 trillion.
  • Preqin names three drivers: digitalisation and connectivity, supply-chain resilience, and rising power and energy security needs.
  • The report's full regional and infrastructure detail is subscriber-only, so APAC-specific infrastructure numbers are not confirmed.

What is Preqin forecasting for infrastructure funds?

Preqin is a private markets data provider. Its Private Markets in 2031 report, published on 21 October 2026, forecasts to end-2031. A Business Wire release dated 28 October 2026 puts infrastructure at US$2.74 trillion, 9.8% annualised, alongside private equity at US$11.6 trillion, private credit above US$5 trillion and venture capital at US$3.79 trillion in the base case. Preqin's own page says private credit and infrastructure funds are expected to grow fastest of all asset classes.

What is driving the infrastructure forecast?

Preqin says the forecast rests on three connected drivers: digitalisation and connectivity, investment in supply-chain resilience, and rising requirements for power and energy security. These map onto themes Alt Asset Asia has covered in the region, including data-centre power demand at https://altassetasia.com/asia-ai-investment-boom-power-problem/ and an Australian infrastructure take-private at https://altassetasia.com/eqt-infrastructure-vi-agrees-a-9-3-billion-cleanaway-deal-what-asia-pacific-allocators-can-read-from-an-australian-take-private/

What does it mean for APAC allocators?

The Business Wire release says Asia-Pacific private markets AUM is approaching US$3 trillion by 2031, against more than US$23 trillion in North America and more than US$7 trillion in Europe. That is a total across all private asset classes, so it should not be compared with the global infrastructure figure. For regional investors such as pension funds, insurers, sovereign investors and family offices, the practical questions are how much of a global infrastructure fund's pipeline is in Asia, how power and digital assets are underwritten, and what fees apply. Alt Asset Asia's earlier reads of the same report are at https://altassetasia.com/preqin-forecasts-private-credit-aum-above-us-5-trillion-by-2031-what-apac-allocators-should-ask/ and https://altassetasia.com/preqin-forecasts-private-equity-assets-nearly-doubling-to-us-12tn-by-2031-what-the-global-outlook-leaves-out-for-apac-investors/ Preqin's Cameron Joyce said returns are likely to be driven less by broad market tailwinds and more by effective manager selection.

What is not confirmed?

  • Asia-Pacific infrastructure AUM: not given in any source reviewed.
  • How the figure compares with Preqin's 2030 report: that report described infrastructure AUM as approaching US$3 trillion by 2030, a higher number than US$2.74 trillion for 2031, and the sources reviewed do not explain the difference, so no like-for-like growth conclusion is drawn.
  • The report itself: it is subscriber-only and was not accessed. Figures other than the page's qualitative findings come from the Business Wire release as syndicated by Yahoo Finance.
