What the filing shows
Microsoft disclosed in a regulatory filing on Wednesday that it generated $10 billion in revenue from commercial arrangements with OpenAI, including revenue-sharing payments, in the quarter ended September 30, 2026, TechCrunch reported. The figure equals nearly 11% of Microsoft's total quarterly revenue of $92.3 billion.
MSFT's fiscal year begins in July, making the quarter the first of fiscal 2027. For the full 2026 fiscal year, OpenAI-related revenue reached $24.1 billion, and at the latest quarterly pace would annualize near $40 billion, according to TechCrunch.
Receivables and ownership
Microsoft reported $7.2 billion in outstanding receivables from OpenAI at the end of September, up from $6 billion at the end of June. The receivables represent amounts owed for prior transactions, not new revenue.
The filing showed Microsoft's ownership stake in OpenAI slipping to about 24% in September from about 25% in June, continuing a gradual decline from roughly 27% after the October 2025 recapitalization. Microsoft did not specify what caused the dilution.
Unresolved split
The filing did not specify how much of the OpenAI-related revenue came from revenue-sharing payments versus Azure cloud services. TechCrunch said it had sought more information.
The two companies have been loosening their once-exclusive partnership. Under an October 2025 agreement, OpenAI committed to buy an additional $250 billion in Azure services, and an April 2026 agreement requires OpenAI to keep sharing revenue with Microsoft through 2030, subject to a cap, even as it works with competing cloud providers.
How much of Microsoft's OpenAI-related revenue comes from revenue-sharing versus Azure?
The filing does not say. Microsoft disclosed the $10 billion combined figure, and TechCrunch reported the split between revenue-sharing payments and Azure services was unspecified.
