Amazon.com Inc. (AMZN) shares rose sharply on Aug. 3, 2026, as investors responded to strong AWS growth and renewed confidence that AI-related cloud demand would sustain margins, pushing the company’s market value above $3 trillion.
Market Value Tops $3 Trillion
Amazon’s market capitalization surpassed $3 trillion for the first time. Shares climbed 5.5% to $286.20 after a 15% gain the previous Friday following the company’s second-quarter report. A premarket surge on July 31 of more than 12% had already set the stage, adding roughly $300 billion in market value. This momentum carried into the new trading week as investors digested the quarterly results.
AWS Growth and Capital Spending
Amazon reported second-quarter revenue of $200.6 billion, a 20% increase year over year. AWS revenue rose 37% to $42.2 billion, marking the company’s strongest cloud growth in over four years. This surge focused investor attention on AWS as the key driver of Amazon’s profit potential.
The company raised its 2026 capital expenditure guidance to $220 billion from $200 billion, citing higher memory costs and investments in AI infrastructure. Investors largely overlooked the increased spending, concentrating instead on AWS’s strong demand and signs of improving margins. Management commented that AWS could eventually reach trillion-dollar annual revenue, though this was presented as commentary rather than formal guidance.
The combination of robust cloud growth and investor willingness to absorb near-term spending led to a revaluation of Amazon’s shares, with greater emphasis on AWS’s ability to monetize AI-driven demand.
