Microsoft posted fiscal Q4 cloud earnings of $59.3 billion, with Azure and related services expanding 43 percent year-over-year. Management confirmed that annual Azure revenue now tops $100 billion, while the Azure AI business run-rate reached $37 billion, implying roughly $9.25 billion in quarterly AI sales and growing 123 percent year-over-year. The commercial RPO backlog stood at $627 billion, and quarterly capex spend was $41 billion. Paid Microsoft 365 Copilot seats surpassed 30 million users, and GitHub Copilot remains the fastest-growing developer tool in company history. Rising capex raised questions about margin timing, but CEO Satya Nadella responded that long-lived assets will translate into higher-margin services as utilization scales. Three catalysts are accelerating enterprise adoption of generative AI: regulatory clarity around data residency, shrinking model-training costs, and Microsoft bundling application access through familiar licensing. Analysts note that the run-rate signals momentum but may overstate steady-state income if demand moderates, though forward contracts inside the $627 billion backlog support Microsoft’s stance that workloads are compounding.
