Microsoft recorded $10B in quarterly revenue from OpenAI arrangements

Microsoft generated $10 billion in revenue from commercial arrangements with OpenAI, including revenue-sharing payments, in the quarter ended September 30. TechCrunch reports that this represented nearly 11% of Microsoft’s total quarterly revenue of $92.3 billion.

The figure shows that OpenAI remains a major financial contributor to Microsoft even as the companies increasingly compete for some of the same customers.

For Microsoft’s full 2026 fiscal year, revenue from OpenAI reached $24.1 billion. At the latest quarterly pace cited by TechCrunch, Microsoft would pull in $40 billion annually from OpenAI-related arrangements.

Microsoft also reported $7.2 billion in outstanding receivables from OpenAI at the end of September, up from $6 billion at the end of June. The article notes that those receivables represent money owed for previous transactions, not additional revenue.

TechCrunch says it is not clear how much of Microsoft’s OpenAI revenue came from revenue-sharing payments versus Azure cloud services. OpenAI reportedly shares 20% of its revenue with Microsoft under a previous deal, though the article notes neither company has publicly confirmed that percentage.

Under an April 2026 agreement, OpenAI is set to continue sharing revenue with Microsoft through 2030, subject to a cap, while also being allowed to work with competing cloud providers.

The companies began loosening their once-exclusive partnership in October 2025, when Microsoft gave OpenAI more freedom to partner with other cloud providers. In exchange, OpenAI committed to buying an additional $250 billion in Azure services as part of that October 2025 agreement.

Microsoft’s ownership stake in OpenAI also declined from about 25% in June to 24% in September, continuing a decline from roughly 27% after the October 2025 recapitalization. Microsoft did not specify what caused the dilution.
