Microsoft Books $10B From OpenAI, 11% of Quarterly Revenue

Microsoft recorded $10 billion in revenue from OpenAI last quarter, according to a 10-Q filing summarized by TechCrunch. "That represents nearly 11% of Microsoft's total quarterly revenue of $92.3 billion, highlighting the enormous financial ties that remain between the two companies," the article states.

Receivables are moving too. "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." For the full 2026 fiscal year, revenue from OpenAI hit $24.1 billion, and at the current quarterly pace Microsoft would pull in $40 billion annually from OpenAI-related arrangements.

The arrangement runs two ways. OpenAI reportedly shares 20% of its revenue with Microsoft under an earlier deal in which Microsoft invested more than $13 billion in the startup. Under an April 2026 agreement, that revenue-share continues through 2030, subject to a cap. In exchange, OpenAI committed to buying an additional $250 billion in Azure services under an October 2025 agreement.

Microsoft's ownership stake slipped slightly over the quarter, from about 25% in June to 24% in September. The disclosure lands alongside our coverage of Microsoft's broader Q1, where Azure growth and a $39.4B capex line set the context for these numbers.
