UAO Research · May 2026 · Infrastructure · A Universal Asset Owners special report
A decade ago infrastructure sat in the "alternatives" sleeve, a small allocation prized for diversification. Today the largest owners increasingly describe it as a core holding — and the reason is a rare alignment of need, cash-flow profile and a new demand driver. The world faces an estimated $15 trillion gap between projected investment and what is needed for adequate infrastructure by 2040 (The world is facing a $15 trillion infrastructure gap by 2040, World Economic Forum / Global Infrastructure Hub.). At the same time, the asset class has acquired a powerful new growth engine: the digital and AI build-out. For a universal owner looking for long-duration, inflation-linked cash flows, that combination is hard to ignore.
What the evidence says
Infrastructure earns its place in the core on the shape of its cash flows. The best assets — regulated utilities, contracted power, transport concessions — offer long-dated, often inflation-linked revenue with high barriers to entry, which is exactly what a long-horizon, liability-matching owner wants. That is why the Canadian and Australian funds built large direct infrastructure programs, and why sovereign and pension capital now competes hard for marquee assets.
The newest and fastest-growing slice is digital infrastructure. Global investment in data centres roughly doubled from 2022 and reached about half a trillion dollars in 2024, with some estimates putting the figure closer to $1 trillion as the AI build-out accelerates (Executive summary — Energy and AI, International Energy Agency.). The physical demand is staggering: the IEA estimates data centres consumed around 415 terawatt-hours of electricity globally in 2024 and projects that to more than double to roughly 945 TWh by 2030. That single statistic ties three of this audience's core themes — AI, energy and infrastructure — into one allocation. Data centres need power; power needs grids and generation; grids and generation are infrastructure.
Where it is contested
The enthusiasm has real risks attached. The first is valuation and crowding: with sovereign, pension and dedicated infrastructure funds all chasing the same contracted assets, entry prices have risen and prospective returns compressed, so discipline matters more than ever. The second is the durability of the digital-infrastructure demand: if the AI capex cycle disappoints, some of today's data-centre and power commitments could prove to be overbuild, and the assets are far less generic than a toll road. The third is policy and rate sensitivity: infrastructure's long-duration cash flows are sensitive to interest rates, and regulated assets carry political and regulatory risk that can change returns with a single ruling. "Core" does not mean "safe" — it means central to the portfolio's risk, which cuts both ways.
From the allocator's seat
For a CIO, treating infrastructure as core changes how it is governed, not just how much is held. It justifies building or buying genuine direct-investing capability, because the fee drag on a large infrastructure allocation through funds is significant over a multi-decade hold. It rewards a barbell within the asset class: stable, regulated, inflation-linked "core" assets for liability matching, alongside a more selective allocation to the higher-growth, higher-risk digital and transition infrastructure where the demand story is strongest. It demands honest underwriting of the AI-linked assets specifically — contracted off-take and creditworthy counterparties rather than speculative demand. And it overlaps deliberately with the energy-transition and demographics allocations, because the same long-duration, inflation-aware cash flows answer several of the universal owner's structural needs at once.
What to watch next
Watch the next IEA data-centre electricity projections and whether the 945-TWh-by-2030 path holds — the clearest signal of how real the digital-infrastructure demand is. Watch grid and transmission investment, the binding constraint on both AI and the transition. Watch private infrastructure fundraising and secondary pricing for signs of crowding or discipline. And watch the largest funds' target allocations: each upward revision to a strategic infrastructure weight is a vote that the asset class has graduated to the core.
