Amazon’s $200 Billion Capex Plan Pushes Big Tech’s AI Buildout to $650 Billion in 2026

Investor skepticism over near-term returns is rising for the massive AI infrastructure push.

Overview

  • Amazon set 2026 capital expenditures at about $200 billion, with the bulk directed to AWS data centers, custom chips, robotics and satellites, sending its shares down more than 10% after hours.
  • Alphabet lifted its 2026 capex target to $175–$185 billion, a sharp step-up from roughly $91 billion in 2025, to expand compute and data-center capacity for AI services.
  • Across Alphabet, Amazon, Meta and Microsoft, planned 2026 outlays for AI infrastructure total roughly $650 billion based on companies’ stated ranges.
  • Markets swung sharply as roughly a trillion dollars of Big Tech market value evaporated, while chip suppliers such as Nvidia and Broadcom rose on expectations of stronger demand.
  • Executives cite compute capacity as the key bottleneck, pointing to constraints in energy, available space and components, even as strong ad and cloud revenues help finance the spending.
