Microsoft Logged $10 Billion in Revenue From OpenAI in a Single Quarter
OpenAI-related arrangements accounted for nearly 11% of Microsoft’s $92.3 billion quarterly revenue, reaching $10 billion in the quarter ended Sept. 30, 2026. Microsoft also reported $7.2 billion in outstanding OpenAI receivables, up from $6 billion in June.
Microsoft generated $10 billion in revenue from commercial arrangements with OpenAI — including revenue-sharing payments — in the quarter ended September 30, 2026, according to a regulatory filing released Wednesday. The figure represents nearly 11% of Microsoft’s total quarterly revenue of $92.3 billion.
For Microsoft’s full fiscal year 2026, revenue from OpenAI reached $24.1 billion. At the latest quarterly pace, Microsoft would pull in roughly $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. That figure represents amounts OpenAI owes for previous transactions, not additional revenue.
The breakdown between revenue-sharing payments and Azure cloud computing services was not disclosed in the filing. Leaked documents reported by TechCrunch in November 2025 indicated Microsoft had received $865.8 million in net revenue-sharing payments from OpenAI during the first nine months of that year. OpenAI is reported to share 20% of its revenue with Microsoft — neither company has publicly confirmed that figure.
The financial relationship stems from Microsoft’s investment of more than $13 billion in OpenAI. Under an April 2026 agreement, OpenAI is committed to sharing revenue with Microsoft through 2030, subject to a cap, even as it gains the ability to work with competing cloud providers. Separately, an October 2025 agreement saw OpenAI commit to purchasing an additional $250 billion in Azure services in exchange for Microsoft relaxing the exclusivity of their partnership.
Microsoft’s ownership stake in OpenAI has also edged down, from approximately 25% in June to 24% in September, continuing a gradual decline from roughly 27% following a recapitalization in October 2025. Microsoft did not specify the cause of the dilution.
The numbers underscore the scale of financial interdependence between the two companies, even as they increasingly compete for the same customers.
