Microsoft said in a regulatory filing Wednesday that it generated $10 billion in revenue in the quarter ending Sept. 30 from a commercial agreement with OpenAI that includes revenue-sharing payments. That’s nearly 11% of Microsoft’s $92.3 billion in quarterly revenue and highlights the enormous economic ties that remain between the two companies, even as they increasingly compete for the same customers.
(Microsoft’s fiscal year begins in July, and the quarter ending September 30, 2026 is the first quarter of fiscal 2027.)
For the entire 2026 fiscal year, revenue from OpenAI reached $24.1 billion. At the latest quarterly rate, Microsoft will extract $40 billion annually from OpenAI-related deals.
Microsoft also reported that it had $7.2 billion in receivables from OpenAI at the end of September, up from $6 billion at the end of June. This amount represents the amount owed by OpenAI for previous transactions, not additional revenue.
It’s unclear how much of Microsoft’s revenue from OpenAI comes from revenue-sharing payments or from Azure’s cloud computing services. TechCrunch is seeking more information. In November 2025, TechCrunch, citing leaked documents, reported that Microsoft received $865.8 million in net revenue distributions from OpenAI in the first nine months of the year.
OpenAI reportedly shares 20% of its revenue with Microsoft as part of a previous deal in which the software giant invested more than $13 billion in the AI startup. (Neither AI lab nor Microsoft have publicly confirmed this percentage.) As part of the April 2026 deal, OpenAI will continue to share revenue with Microsoft through 2030, subject to caps, although it is allowed to work with competing cloud providers.
The two companies began loosening their once exclusive partnership in October 2025, when Microsoft relinquished control over OpenAI, allowing the startup to partner more freely with other cloud providers. In return, OpenAI committed to purchasing an additional $250 billion in Azure services as part of the October 2025 deal.
Microsoft’s stake in OpenAI also fell slightly from about 25% in June to 24% in September. This continues to decline gradually from around 27% after the October 2025 recapitalization. Microsoft has not disclosed the cause of the dilution.
