Microsoft reported $10 billion in revenue from its commercial arrangements with OpenAI for the quarter ending September 30, 2026. This figure represents nearly 11% of Microsoft's total quarterly revenue of $92.3 billion. For the full fiscal year 2026, revenue from OpenAI reached $24.1 billion.
The reported revenue includes payments from revenue-sharing agreements and potentially Azure cloud computing services. Microsoft also disclosed $7.2 billion in outstanding receivables from OpenAI at the end of September, an increase from $6 billion at the end of June, representing amounts owed for past transactions.
OpenAI reportedly shares 20% of its revenue with Microsoft as part of an earlier investment deal. An April 2026 agreement extends this revenue-sharing through 2030, subject to a cap, even as OpenAI gains flexibility to work with other cloud providers.
The financial reporting occurs as the partnership between Microsoft and OpenAI evolves. In October 2025, Microsoft loosened its exclusive hold on OpenAI, allowing the startup more freedom to partner with competing cloud providers. In exchange, OpenAI committed to purchasing an additional $250 billion in Azure services.
Microsoft's ownership stake in OpenAI also saw a slight decline, moving from approximately 25% in June to 24% in September, continuing a gradual reduction from about 27% after a recapitalization in October 2025.
