Methodology

Two source-backed charts: 2026 AI capex by company ($B) and combined hyperscaler AI capex versus the US FY2026 defense budget ($B). Per-company figures (Amazon ~$200B, Alphabet ~$185B, Meta ~$125B, Microsoft ~$120B) trace to the cited capex analysis. The aggregate ~$675B is the midpoint of the $660–690B range for the five largest US cloud/AI providers (incl. Oracle), up ~77% YoY from ~$410B. Defense ~$1T reflects $838.7B appropriations + $150B via reconciliation (topline cited near $1.05T). CAVEAT: company capex is largely but not exclusively AI. The popular claim that tech will out-spend the military is a forward projection — in 2026 defense is still the larger number. Re-verified 2026-07-17.
