Big Tech Lifts AI Capex to About $380 Billion as Cloud Growth Reaccelerates

Wall Street is pressing for clearer payoffs, with companies insisting demand already exceeds capacity.

Overview

  • Microsoft logged a record near-$35 billion quarter of capital spending and said AI capacity will remain constrained through June 2026 as outlays accelerate next fiscal year.
  • Amazon projected about $125 billion in 2025 capital expenditures with more planned for 2026, while AWS revenue rose 20% to $33 billion and investor reaction turned positive.
  • Alphabet raised its 2025 capex outlook to $91–$93 billion, saying the vast majority funds AI infrastructure, as Google Cloud revenue grew 34%.
  • Meta narrowed its 2025 capex range to $70–$72 billion and signaled a notably larger 2026, a stance that weighed on shares as investors questioned the path to returns.
  • Executives and policymakers defended the spending even as bubble worries persist, with firms noting short-lived GPUs drive replacement needs and some projects tapping debt markets.
