Amazon shares closed October 2026 near $244 after a sharp post-earnings decline triggered by Amazon’s Q3 results, which missed consensus on revenue ($201.9 billion) and EPS ($1.89). Traders focused on elevated capital expenditures of $220 billion for the year and a trailing-twelve-month free cash flow swing to negative $42.4 billion, reflecting heavy AI infrastructure spending that pressured margins and liquidity metrics despite record operating income of $28.1 billion. AWS delivered the strongest offset, accelerating to 39% year-over-year growth and positioning the segment for sustained above-40% expansion in 2027–2028. With October nearly complete, market-implied odds for price thresholds now incorporate this earnings reaction, elevated volatility around AI capex trajectories, and limited remaining catalysts before quarter-end.
