Spending on data centers is reaching a scale without precedent, with global capital expenditure forecast to surpass 1 trillion dollars for the first time in 2026, according to figures from Dell'Oro Group alongside market data compiled by Statista. The surge is concentrated among a handful of U.S. technology giants racing to build capacity for artificial intelligence.

Hyperscaler budgets tell the story. The top four U.S. cloud providers, Amazon, Google, Meta, and Microsoft, lifted their combined data center capital spending 76 percent in 2025 to roughly 420 billion dollars. For 2026, combined spending by the largest five hyperscalers is projected to exceed 600 billion dollars, a 36 percent year-over-year increase.

The revenue base underneath that investment is also large. Worldwide data center market revenue is forecast to reach about 538.91 billion dollars in 2026, with network infrastructure the biggest segment at roughly 284.01 billion dollars. The United States leads all countries, generating an estimated 168.51 billion dollars in data center revenue for the year, ahead of every other national market.

The spending wave reflects a bet that demand for AI compute will keep rising. It also raises the stakes for power supply, since each dollar of capex eventually translates into new electricity load that utilities must serve. The concentration of investment among a few firms means a small number of corporate decisions now shape construction pipelines and grid planning across large parts of the country.
