Azure Sprints, AWS Posts Its Fastest Quarter in Years

Microsoft's fiscal Q4 2026 pulled in $90.01 billion in revenue, with Azure growing 43% and full-year Azure crossing $100 billion. Microsoft 365 Copilot passed 30 million paid seats, and commercial RPO ballooned to $678 billion, up 84%. Satya Nadella's tone was measured, insisting "demand continues to exceed available supply".

Amazon's Q2 2026 was arguably louder. Revenue hit $200.61 billion, and AWS grew 37% to $42.23 billion, its fastest pace in 18 quarters, at a 39.4% operating margin.

Different Answers to the Same Model-Risk Problem

Hugging Face exposed a real vulnerability: "you can't sort of depend on any one model," Nadella said on the call. Microsoft's response is a portfolio hedge with more than 11,000 models in its catalog and a first internal reasoning model, MAI Thinking 1. Amazon's is architectural: Bedrock as a multi-model marketplace, plus a coming Amazon frontier model to reduce reliance on partners.
