Amazon Q3 Capex Surge Drives $33.5B Cash Burn, Stock Drops 12%

Amazon's quarterly filing shows operating cash flow of $42.4 billion offset by $75.9 billion net capex, pushing trailing twelve-month free cash flow to -$42.4 billion. The company simultaneously issued $48.1 billion in long-term debt. AWS revenue grew 39.3% year-over-year, below the 42% buyside threshold priced into prior rallies, while operating income reached $28.1 billion in line with estimates.

Q4 guidance brackets revenue at $240-247 billion and operating income at $28.5-33.5 billion, both below Street and whisper numbers. The reaffirmed $220 billion 2026 capex target implies a sharp Q4 slowdown despite management statements that demand exceeds supply. Goldman Sachs noted the outcome as neutral to slightly weaker across most segments.

The divergence between capex trajectory and cash generation mirrors patterns seen in prior infrastructure buildouts at hyperscalers, where front-loaded spending precedes multi-year utilization ramps. Bond issuance data from the quarter indicates reliance on debt markets to fund the gap rather than internal operations.

Markets will next test whether 2027 capex commentary emerges before the Q4 release or whether further debt issuance signals sustained negative free cash flow into 2027.
