Amazon Cloud Grows 28% While Graviton/Trainium Chips Could Generate $50B
Amazon Web Services revenue grew 28% year-over-year in Q1 2026, lagging Google Cloud’s 63% and Microsoft Azure’s 40% growth as cloud infrastructure spending accelerates. Amazon’s Graviton and Trainium chips support a $20 billion internal revenue run rate with potential to reach $50 billion by selling externally.
1. AWS Q1 Revenue Performance
Amazon Web Services posted 28% year-over-year revenue growth in Q1 2026, falling behind Google Cloud’s 63% and Microsoft Azure’s 40% gains. This slower pace underscores increasing competition in cloud infrastructure as enterprises race to deploy AI workloads.
2. AI Infrastructure Capex Surge
Big tech spent a combined $130.6 billion on cloud and AI infrastructure in the first quarter, fueling data center expansions and hardware procurement. Annual investments are on track for nearly $700 billion, driven by rising memory chip costs, which have surged roughly 50% this year.
3. Graviton and Trainium Chip Outlook
Amazon’s in-house Graviton and Trainium processors deliver a $20 billion revenue run rate for internal AWS use, with plans to open sales to third parties once production capacity expands. Management targets potential external revenue of $50 billion, aiming to rival established chip vendors.
