Microsoft generated $10 billion in revenue from commercial arrangements with OpenAI, including revenue-sharing payments, in the quarter ended September 30, the company disclosed in a regulatory filing on Wednesday. This figure represents nearly 11% of Microsoft's total quarterly revenue of $92.3 billion, underscoring the deep financial connections between the two partners despite their growing competition in the artificial intelligence market. For the full 2026 fiscal year, revenue derived from OpenAI reached $24.1 billion, and at the current quarterly pace, Microsoft could pull in $40 billion annually from these arrangements.

Additionally, Microsoft reported $7.2 billion in outstanding receivables from OpenAI at the end of September, an increase from $6 billion at the end of June, representing funds owed for previous transactions rather than new revenue. Although the precise breakdown between Azure cloud computing services and revenue-sharing payments remains unclear, reports indicate that OpenAI agreed to share a portion of its revenue with Microsoft through 2030 under an April 2026 agreement. The companies have gradually loosened their exclusive ties since October 2025, when Microsoft gave OpenAI more freedom to work with competing cloud providers in exchange for a commitment to purchase $250 billion in Azure services.

During this period, Microsoft's ownership stake in OpenAI experienced a slight decline, dropping from about 25% in June to 24% in September, continuing a steady dilution from 27% following a recapitalization in late 2025. This financial milestone demonstrates the massive economic scale of the partnership, even as both organizations adjust their corporate structures and pursue independent commercial strategies.
