Filing said OpenAI generated $24.1 billion of Microsoft AI sales in fiscal 2026, while Microsoft also reported Azure growth, a more than $37 billion AI annual recurring revenue run rate and custom-chip gains.
Microsoft disclosed in a filing that sales from OpenAI reached $24.1 billion in the fiscal year ended June 30, 2026, indicating OpenAI accounted for more than half of Microsoft's AI sales and possibly about 70%. The disclosure follows CEO Satya Nadella's earlier statement that Microsoft's AI business had surpassed a $37 billion annual recurring revenue run rate, up 123% year over year, as Azure revenue rose 43% in fiscal Q4 2026. Nadella also said Microsoft's in-house AI chips improved Copilot inference throughput by 40%, while the Maia 200 accelerator delivered more than 30% better tokens per dollar than prior hardware. Microsoft said it continues to work with Nvidia and AMD even as it expands its own chip program, and spent about $41 billion on AI infrastructure capital expenditures during the quarter.
