Amazon added roughly $390 billion in market value in a single trading session, its best single-day gain in 14 years, after a Q2 2026 earnings report showing sharply faster AWS revenue growth. Amazon also raised its full-year capital spending guidance to roughly $200 billion.
Amazon stock surged 15.32% in a single session, its best single-day performance in 14 years. The driver wasn't e-commerce — it was AWS.
AWS posted $42.2 billion in quarterly revenue, a 37% year-over-year jump marking the cloud division's strongest growth in over four years. Overall Amazon revenue hit $181.5 billion for the quarter, up 17% year-over-year, with record operating margins.
The unit's growth had already run at 28% in Q1 2026, so the acceleration to 37% in Q2 caught even optimistic analysts off guard. Amazon had underperformed its mega-cap peers for much of 2026 before this earnings report reset the conversation.
Separately, Amazon raised its full-year capital expenditure guidance to roughly $200 billion, almost entirely driven by AI-related infrastructure demand. The earnings landed on July 30, and intraday gains reached as high as 12.99% before the stock closed up over 15%.
The company isn't alone in the buildout. Microsoft, Google, and Meta are all making similar bets, collectively directing hundreds of billions toward AI infrastructure this year. AWS's 37% growth rate suggests the buildout is still accelerating, not plateauing.
