AI Capital Expenditure
AI Infrastructure Spending Is Set to Hit $497 Billion in 2026
The five biggest US cloud providers alone will spend up to $690 billion on capex in 2026 — nearly double 2025 levels — as global data center spending surpasses $788 billion.
AI infrastructure spending has moved from a notable trend to one of the largest capital allocation stories in the global economy.
The scale of the build-out
Microsoft, Alphabet, Amazon, Meta, and Oracle together plan to spend between $660 billion and $690 billion on capital expenditure in 2026 — nearly double 2025 levels, and more than the GDP of Switzerland by some comparisons. Global data center spending overall is projected to grow 55.8% in 2026, surpassing $788 billion (Gartner), while AI-specific infrastructure spending is forecast at $497 billion, up from a Q1 2026 run-rate near $90 billion (IDC).
Where the money is going
The US leads with roughly $240 billion, about 60% of global AI-infrastructure spending. The Middle East — particularly Saudi Arabia and the UAE — posted the strongest year-over-year growth in Q1 2026, driven by government-backed sovereign AI initiatives and hyperscaler partnerships.
Why it matters
This is capital spending happening well ahead of confirmed enterprise ROI (see our piece on enterprise AI's ROI problem) — meaning the infrastructure build-out is currently a bet on future demand materializing, not a response to already-proven returns.
