Amazon Web Services just posted its best growth quarter in nearly four years, and the reason is exactly what you’d expect: everyone suddenly needs a lot more compute power to run AI workloads. The cloud giant reported Q1 FY2026 revenue of $37.6 billion, a 28% jump year-over-year, with record operating margins of 13.1%.

That’s the fastest AWS has grown in 15 quarters.

The numbers behind the AI gold rush

AWS now carries an annualized revenue run rate of $150 billion. AWS’s revenue run rate for AI-related services has surpassed $15 billion.

Amazon has outlined capital expenditure plans approaching $200 billion for 2026, with the lion’s share directed at AI infrastructure. That includes new data centers, proprietary chips like Trainium and Graviton, and Project Rainier, a large-scale AI compute cluster designed to handle the most demanding workloads.
