OpenAI Generates $10B, or 11%, of Microsoft Q1 Revenue as Azure Grows 48%

Microsoft recorded $10B in fiscal first quarter revenue from OpenAI, accounting for nearly 11% of its $92.28B quarterly total, alongside $7.2B in outstanding receivables from the AI developer and a $207M net gain that added $0.03 to earnings per share. Overall first quarter revenue rose 19% year over year to top the $90.63B consensus estimate, while adjusted EPS climbed 18% to $4.89, beating the $4.73 estimate, sending shares up 4% to 5% in after hours trading.

Azure revenue rose 48% to $33.17B, ahead of the $32.32B estimate and driving roughly 74% of Microsoft’s total revenue increase, as broader Microsoft Cloud sales grew 30% to $63.9B. CFO Amy Hood said higher than expected AI token pricing on high margin models lifted Azure in the quarter, while CEO Satya Nadella said Microsoft docked its first Nvidia Vera Rubin GPUs, added 24 data centers across five continents and improved Copilot workload throughput by more than 50% from the prior quarter.

For the second quarter, Microsoft guided revenue to between $96.0B and $97.1B, above the $95.62B estimate, with Azure constant currency growth accelerating to 49% to 50% against a 44.6% forecast as customer demand continues to exceed available supply. The company projected second quarter capital expenditures above $50B and trimmed its calendar 2026 capex outlook to about $170B from $175B after third party capacity deliveries and GPU as a service contracts shifted into the second half of fiscal 2027, following first quarter capex of $39.37B, or $45.2B including finance leases.

AI Growth Compounds

Investors treat the $10B OpenAI contribution and 48% Azure growth as evidence that Microsoft has converted AI infrastructure spending into scaled revenue. The most likely path is continued enterprise adoption of Azure AI, OpenAI APIs, and Microsoft 365 Copilot, with debate shifting from demand validation to margin durability.

Capacity Bottlenecks Bite

The main risk is that demand is strong enough to expose shortages in GPUs, data-center power, networking, and cooling. In this path, Microsoft can sell the AI cloud capacity it builds, but investors worry about capital intensity and the timing of supply additions.

Regulatory Scrutiny Builds

The disclosure that OpenAI accounts for 11% of Microsoft quarterly revenue could intensify scrutiny of cloud concentration, AI model access, and Microsoft’s influence over a public-benefit corporation. This is a lower-probability path, but the revenue dependence makes the regulatory argument more concrete.
