Microsoft Books $10 Billion From OpenAI as Azure Grows 48%
Microsoft recorded $10 billion in revenue from its commercial arrangements with OpenAI, including revenue-sharing payments, in the quarter ended September 30, 2026, according to TechCrunch. That figure is nearly 11% of the company's total quarterly revenue. Microsoft published the results on October 28, 2026, after the close of the market.
Total revenue for the quarter was $92.3 billion. Analysts had expected $90.66 billion, a 16.7% year-over-year increase, according to Reuters. Operating income was $45.9 billion, up 21% year-over-year, or 22% in constant currency.
Microsoft reported GAAP net income of $36.6 billion, up 32%, and GAAP diluted earnings per share of $4.92, also up 32%. On a non-GAAP basis, net income was $36.4 billion, up 18%, and diluted EPS was $4.89, up 18%. The non-GAAP figures exclude the impact of Microsoft's investments in OpenAI, which is why the two measures diverge by a wide margin in this quarter. Readers comparing the two should note that the gap is driven by that exclusion rather than by operating performance.
Azure revenue rose 48% year-over-year. Microsoft Cloud revenue reached $63.9 billion, up 30% (31% in constant currency). The company reported Agents and Infra revenue of $76.8 billion, up 25%. Commercial remaining performance obligation increased 73% to $677 billion. Microsoft 365 consumer cloud revenue grew 17%, and industry solutions cloud revenue grew 10%.
The OpenAI relationship is now documented in several figures. Microsoft's revenue from OpenAI for the full fiscal 2026 year was $24.1 billion. Its receivables from OpenAI stood at $7.2 billion at the end of September 2026, up from $6 billion at the end of June 2026. Microsoft's ownership stake in OpenAI declined from about 25% in June 2026 to 24% in September 2026. Under an October 2025 agreement, OpenAI committed to buying an additional $250 billion in Azure services from Microsoft. Under an April 2026 agreement, OpenAI is to continue sharing revenue with Microsoft through 2030, subject to a cap, and is permitted to work with competing cloud providers.
Because Microsoft's fiscal year begins in July, the September quarter is the first quarter of fiscal 2027, not a continuation of the fiscal 2026 numbers reported earlier in the year.
The mechanics are worth spelling out for anyone modeling the business. Microsoft's OpenAI-linked revenue arrives through a mix of Azure consumption, revenue-sharing and related commercial terms, and the $250 billion commitment is a forward purchase obligation that will be recognized as Azure capacity is consumed. The receivables increase of $1.2 billion within a single quarter is a reminder that large counterparty balances accumulate on the books before they are collected. The stake reduction, from 25% to 24% over three months, is recorded in the same filing and is a separate line item from the commercial revenue.
In my view, the notable feature of these results is how concentrated the dependency has become on both sides. OpenAI accounts for a material share of Microsoft's quarterly revenue, and Microsoft's cloud backlog is partly tied to a single customer's commitment. The April 2026 terms that allow OpenAI to work with competing cloud providers reduce the exclusivity that once defined the arrangement, which cuts both ways for Azure's long-term growth profile.
The broader context here is that the same disclosures show the cloud business growing on its own terms. Azure's 48% growth and the 73% rise in remaining performance obligation describe demand that extends well beyond one partner, even as the OpenAI line items draw the most attention. For infrastructure teams, the practical question is how quickly that backlog converts into deployed capacity, and the company's results give no timetable for that conversion beyond the figures already stated.
