Amazon reports record operating margin but negative free cash flow as AI capex surges

Amazon posted Q3 2026 revenue of $201.9 billion, up 12% year‑over‑year, and a record operating margin of 13.9%. AWS revenue jumped 39% to $45.98 billion with operating income of $17.8 billion. However, free cash flow turned negative at $42.4 billion because the company is spending about $220 billion on AI‑related capital expenditures in 2026. The earnings release triggered mixed stock moves, with the share price falling 6.5% in after‑hours trading and rising 3‑4% in intraday sessions.

The strong AWS growth supports Amazon’s long‑term earnings outlook, but the massive negative free cash flow highlights short‑term cash‑burn risk from AI infrastructure spending. Investors will watch whether the $220 billion capex plan translates into sustained revenue and cash‑flow generation.
