Azure Finally Has a Number: $33.2 Billion, and $10 Billion of Microsoft's Quarter Came From OpenAI

Microsoft opened fiscal 2027 with its tenth consecutive record quarter: $92.3 billion in revenue for the three months ended September 30, up 19 percent year over year and ahead of the roughly $90.6 billion analysts expected. Net income reached $36.6 billion, up 32 percent on a GAAP basis, with diluted EPS of $4.92. On a non-GAAP basis, which strips out the accounting impact of its OpenAI investment, earnings were $4.89 per share, up 18 percent. The stock, which closed slightly down at $531.01, jumped in after-hours trading.

The headline number was one Microsoft had never printed before: Azure's quarterly revenue in dollars. The company has historically disclosed only growth percentages for its cloud, but this quarter it reported that Azure brought in $33.2 billion, up 48 percent and about $10.8 billion more than a year earlier. That beat the $32.3 billion analysts modeled and exceeded the 44-to-45-percent growth range CFO Amy Hood had forecast in July. Azure now accounts for roughly 36 percent of Microsoft's total revenue and is the company's largest single product line by its own figures.

The disclosure also puts Azure side by side with rivals that already report cloud revenue in dollars. Alphabet, which reported the same evening, put Google Cloud at $30.7 billion for the same quarter — slightly smaller, but growing at roughly twice Azure's rate. Amazon reports on Thursday, and with all three hyperscalers now on the same scorecard, the cloud race gets a lot easier to track.

Buried in the regulatory filing is another striking figure: Microsoft recorded $10 billion of revenue from commercial arrangements with OpenAI in the quarter, including revenue-sharing payments. That is nearly 11 percent of Microsoft's total revenue from a single counterparty. For the full 2026 fiscal year the figure was $24.1 billion, and at the current pace it would run to about $40 billion annually. Microsoft also carried $7.2 billion in outstanding receivables from OpenAI at the end of September, and its ownership stake slipped from about 25 percent to 24 percent as the partnership continues to loosen — OpenAI committed to an additional $250 billion in Azure purchases in its October 2025 agreement, while revenue sharing continues through 2030 subject to a cap.

Demand shows up most clearly in contracted future revenue: commercial remaining performance obligations jumped 73 percent to $677 billion, the clearest signal yet that AI labs and enterprises have committed to multi-year cloud spending. Under a new reporting structure that took effect this quarter, the Agents and Infra segment — which groups Azure with Microsoft 365's cloud business, Dynamics and LinkedIn — brought in $76.8 billion, up 25 percent, with operating income of $40.6 billion. The Devices and Consumer segment fell 3 percent to $15.5 billion, with Windows OEM and devices revenue down 22 percent.

All that demand still has to be built. Capital spending on property and equipment came in at $39.4 billion, more than double the $19.4 billion a year earlier, though below the $45.9 billion consensus; including finance leases, secondary coverage put the figure at $45.2 billion. Operating cash flow grew 29 percent to $58 billion, and Microsoft returned $10.2 billion to shareholders through dividends and buybacks.

The quarter is a snapshot of the AI buildout converting into revenue rather than just cost: cloud growth accelerated, spending came in under expectations, and a single customer — OpenAI — now contributes one in nine revenue dollars. The open question for Thursday is whether Amazon's AWS, the largest cloud by revenue since its inception, can match Azure's 48 percent. With everyone disclosing dollars, the argument about who is actually winning the AI infrastructure market just got a scoreboard.
