Big Four hyperscaler capex set to hit ~$725bn in 2026, up 77%
Amazon ~$200bn, Microsoft ~$190bn, Alphabet $175–185bn, Meta $125–145bn, a combined AI buildout larger than most national budgets, with component inflation now a line item
Summary
The four largest US hyperscalers are guiding to roughly $725bn of 2026 capital spending, up about 77% from a record $410bn in 2025. By company: Amazon ~$200bn, Microsoft ~$190bn, Alphabet $175–185bn, Meta $125–145bn (raised mid-year on component pricing and added data-center costs). Microsoft says ~$25bn of its $190bn is component-price inflation. Alphabet reported Q1 capex of ~$35.7bn (more than double year-on-year) and a Google Cloud backlog above $460bn; Microsoft's fiscal-Q3 capex hit ~$30.9bn (up ~84%). Nearly all of the spend funds AI data centers and Nvidia / custom-silicon compute. Critics flag the cash-flow strain and circular financing; bulls call demand real.
By the numbers
- ~$725bn, combined 2026 capex guidance, four firms (up ~77%).
- ~$200bn / ~$190bn / $175–185bn / $125–145bn, Amazon / Microsoft / Alphabet / Meta.
- ~$25bn, share of Microsoft's 2026 capex attributed to component inflation.
$460bn, Google Cloud backlog reported in Q1 2026.
- ~84%, year-on-year jump in Microsoft fiscal-Q3 capex.
Why it matters
A near-doubling of capex at four firms concentrates an industrial-scale bet on AI demand, pressuring free cash flow, power grids and component supply chains. If demand lags the build, the exposure, and the circular vendor financing under it, becomes the market's central risk.
What to watch
- Whether any of the four trims or defers 2026 guidance on a demand wobble.
- How much further component inflation lifts the headline figures.
- Free-cash-flow and debt-issuance trends as spend outruns operating cash.
