What I Learned about Hyperscalers’ AI Spend
Brief
Hyperscalers are dramatically accelerating AI‑driven infrastructure spend: Microsoft, Meta, Amazon and Alphabet collectively guided roughly $700–710B of 2026 capex (about double 2025’s ~$370B), with Microsoft (~$190B), Meta (125–145B), Alphabet (180–190B) and Amazon (~$200B) leading. Much of the increase reflects component price inflation (Microsoft cites ~$25B) and capacity additions; Q1/Q3 year‑over‑year quarter moves show capex roughly doubling (e.g., Alphabet Q1 2025→Q1 2026: $17B→$36B). Two‑thirds of some recent spend is on short‑lived GPUs/CPUs, accelerating depreciation and squeezing free cash flow (Amazon TTM FCF collapsed to ~$1B; Microsoft and Alphabet FCF down 22% and 38%). The picture is clouded by non‑cash equity gains (Alphabet $36.8B, Amazon $16.8B, Microsoft $5.9B) and large off‑balance‑sheet commitments (Moody’s ~$662B leases, Meta +$107B commitments in one quarter), revealing significant prepayments, SPV funding and financial engineering alongside real AI engineering investment.
Why it matters
Microsoft, Meta, Amazon and Alphabet told investors they will spend roughly $705–710 billion in capex in 2026 (article cites ~700B), nearly double combined 2025 spend (~$370B); three raised 2026 guidance while Amazon held a prior $200B forecast.
Key details
- Company-level 2026 guides: Meta $125–145B (from $72B in 2025, ~+85% mid), Microsoft ~$190B (from ~$118B, ~+61%; Microsoft says ~$25B of that is component price inflation), Alphabet $180–190B (from $91B, ~+102%), Amazon ~$200B (from $88B TTM, ~+60%).
- Quarterly capex jumped: Meta Q1 capex 13→20B, Alphabet 17→36B, Microsoft cash capex Q3 FY26 17→31B, Amazon ~25→44B; two‑thirds of Microsoft’s recent capex went to short‑lived assets (GPUs/CPUs) that depreciate in ~3–5 years, pressuring operating margins.
- Financial engineering and off‑balance‑sheet commitments are large: Moody’s noted ~$662B in signed-but-not-commenced data center lease commitments; Meta’s contractual commitments rose by ~$107B in one quarter (implied ~190B at Mar 31, 2026); Alphabet disclosed $232.7B non‑cancelable commitments and a $467.6B backlog (≈55% expected to convert to revenue in 24 months).
