Amazon.com IncAWS backlog surged 49% to $364B, driven by large commitments from AI startups, and AWS revenue grew 28% YoY.

Amazon Web Services ended the first quarter with a $364 billion backlog, up 49% from the prior quarter, driven in part by a $138 billion commitment from OpenAI and a subsequent $100 billion deal with Anthropic. The two AI startups have a combined annualized revenue run rate of $72 billion, yet their total yearly spending commitment to AWS alone equals about 38% of that figure, not counting obligations to other cloud providers or operating costs. Amazon plans $200 billion in capital expenditures for 2026, and consensus estimates point to $11 billion in negative free cash flow for the year. AWS revenue grew 28% year over year in the quarter, its fastest pace in more than three years, and the unit now accounts for 59% of Amazon's total operating income.
