Microsoft AI Revenue Hits $37 Billion Annualized, Up 123% YoY
View original source →Microsoft reported strong Q1 2026 results on April 29: its AI-specific business is running at $37 billion in annualized revenue, up 123% year-over-year, with Azure cloud growth driven primarily by AI workloads. Microsoft raised full-year capex guidance to over $40 billion.
Key Points:
• AI business annualized revenue: $37 billion, up 123% YoY — the fastest-growing revenue line in Microsoft's history.
• Azure AI workloads are the primary growth driver, with enterprises deploying Copilot and custom Azure OpenAI Service at scale.
• Full-year 2026 capex guidance raised to over $40 billion, prioritizing AI compute and data center expansion.
• Microsoft's stock dipped after-hours due to elevated capex commitment — investors are monitoring the return timeline on infrastructure investment.
A $37B annualized AI revenue run rate makes Microsoft the world's largest commercial AI company by revenue — ahead of OpenAI, Anthropic, and Google's AI-specific lines. The AI monetization race has a clear early leader.
Why It Matters: The 123% YoY growth rate indicates enterprise AI adoption has crossed the early adopter phase. Mainstream enterprise deployment is well underway, and Microsoft is capturing the majority of the budget.
