April 29: Big Tech Q1 capex hits $130B in a single quarter, with capacity already sold out
Microsoft, Google, Meta, and Amazon all reported Q1 2026 earnings on Wednesday, and the headlines converged on one observation: AI is selling faster than the hyperscalers can build for it. Microsoft's AI business hit a $37B annual run rate (up 123% year-over-year), with M365 Copilot at 20M paid enterprise seats and Accenture alone signing 740,000 of them. Google Cloud grew 63% to $20B, but Sundar Pichai said cloud revenue would have been higher had Google built fast enough; the cloud backlog doubled in one quarter to $462B. AWS grew 28% (its fastest in 15 quarters), and Amazon's custom Trainium and Graviton chip business passed a $20B run rate, with OpenAI committing 2 GW and Anthropic up to 5 GW of Trainium capacity. Meta raised 2026 capex guidance to $125–145B, citing memory pricing and additional data-center costs.
So what
Cloud growth rates used to tell you who was winning; now they tell you who has the most concrete poured. For growth-company CEOs, the practical implications are concrete. First, capacity is now a real risk in vendor selection: ask explicitly whether a vendor can guarantee inference capacity at your forecast volumes, and whether their primary cloud has waitlists. Second, expect AI line-item costs to continue rising through 2026 as memory and component pricing eats into hyperscaler margins; build a 20–30% buffer into FY26 AI budgets. Third, the hyperscaler that locks you in on custom silicon (Trainium on AWS, TPU on Google) gets compounding margin advantage. Take a hard look at your cloud commitments before the next renewal.
Hype check
The "demand exceeds supply" narrative is convenient cover for raising capex guidance, and Amazon's trailing-twelve-month free cash flow fell 95% from $25.9B to $1.2B largely because of this spending; if AI revenue does not catch up to the chip bill, the rest of Big Tech's cash flow eventually starts to look the same.
Confidence: Established fact — revenue figures and capex guidance are from the companies' own Q1 earnings releases and 10-Q filings.
