A new Visual Capitalist analysis of data from Epoch AI shows just how fast AI infrastructure spending has grown among the largest US technology companies. Combined capital expenditures at Alphabet, Amazon, Meta, Microsoft, and Oracle climbed from a fraction of that level in 2022 to a combined 448 billion dollars by 2025, driven almost entirely by AI data center and chip investment.

The spending surge lines up with separate McKinsey research on enterprise AI budgets published in July 2026. McKinsey's Enterprise AI FinOps survey of 120 companies found that AI spending increases nearly fourfold as organizations move from isolated pilot projects to enterprise-wide deployment. Sixty-two percent of organizations surveyed have already moved past the experimentation stage into active AI deployment.

That growth is creating budget strain. Ninety-three percent of respondents in the McKinsey survey said they have exceeded their AI budgets, and most firms expect AI spending to rise by at least 25 percent over the next 12 months. McKinsey found that only 20 to 25 percent of companies currently have mature AI cost management practices in place. Organizations that actively manage AI consumption are capturing savings of 20 to 30 percent.

Together, the two data sets point to a market still in the early stages of figuring out how to budget for AI at scale, even as the dollar figures involved grow larger every quarter.
