Microsoft posts record $92.3B quarter, disclosing $10B from OpenAI and Azure at $33.2B

Microsoft closed the quarter ended September 30 with $92.3 billion in revenue, its tenth consecutive record quarter, and a regulatory filing gave an unusually direct view of where the AI boom sits in its books: $10 billion of that revenue came from arrangements with OpenAI, while Azure contributed $33.2 billion, according to TechCrunch.

A tenth straight record quarter

Quarterly revenue rose 19% year over year, and net income climbed 32% to $36.6 billion on a GAAP basis, TechCrunch reports. Microsoft Cloud generated $63.9 billion, up 30%.

The company now reports its business in two segments: Agents and Infra, and Devices and Consumer. The consumer side lagged, with Devices and Consumer revenue of $15.5 billion, a 3% decline, and Windows OEM and device revenue falling 22% from a year earlier.

Within the cloud business, Microsoft 365 accounted for nearly $28 billion, but Azure was the single largest contributor at $33.2 billion. Not all of that is AI-driven, since enterprises run plenty of conventional software on Azure. Still, AI labs loom over Microsoft's future commitments: commercial remaining performance obligation jumped 73% to $677 billion, which TechCrunch describes as future revenue committed under the AI labs' existing contracts. Serving that pipeline is expensive — capital expenditures topped $45.2 billion, another all-time quarterly record.

What the OpenAI numbers show

In a filing on Wednesday, Microsoft said it recorded $10 billion in revenue from commercial arrangements with OpenAI, including revenue-sharing payments, during the quarter. TechCrunch notes that this is nearly 11% of total quarterly revenue — a striking concentration for a single commercial partner that also competes with Microsoft for customers. (Microsoft's fiscal year begins in July, making the September quarter the first of fiscal 2027.)

The filing adds context around the figure. For the full fiscal 2026 year, OpenAI-related revenue reached $24.1 billion, and at the latest quarterly pace it would annualize to roughly $40 billion. Microsoft also holds $7.2 billion in receivables from OpenAI as of the end of September, up from $6 billion at the end of June — money OpenAI owes for previous transactions, not additional revenue.

How the $10 billion splits between revenue sharing and Azure services is not clear. Citing leaked documents, TechCrunch previously reported that Microsoft received $865.8 million in net revenue-sharing payments from OpenAI in the first nine months of 2025. OpenAI is reportedly obliged to share about 20% of its revenue with Microsoft, tied to the software maker's investment of more than $13 billion, though neither company has publicly confirmed the percentage. Under an April 2026 agreement, those payments continue through 2030, subject to a cap, even as OpenAI is free to work with competing cloud providers.

The partnership was loosened in October 2025, when Microsoft gave up its hold over OpenAI in exchange for a commitment from the startup to buy an additional $250 billion in Azure services. Since then, Microsoft's equity stake in OpenAI has gradually declined — from roughly 27% after the October 2025 recapitalization to about 25% in June and 24% in September. Microsoft did not say what caused the dilution.

Competitors and customers at once

The two companies increasingly chase the same enterprise customers, yet OpenAI still runs a large share of its services on Azure even after expanding to AWS, Oracle and other providers. Anthropic also runs on Microsoft's cloud, according to TechCrunch.

Why it matters

These disclosures put hard numbers on questions that have mostly been discussed in generalities: how much direct revenue a leading AI lab generates for its biggest backer, and how much hyperscaler growth now depends on a handful of AI customers. Roughly 11% of quarterly revenue tied to one partner is significant concentration, and it arrives alongside a $677 billion backlog that only converts to income if Microsoft keeps building — hence record capital spending of $45.2 billion. For anyone tracking whether the AI infrastructure buildout pays for itself, Microsoft's books have become one of the clearest places to watch.
