Microsoft has reported a significant financial gain from its commercial arrangements with OpenAI, recording $10 billion in revenue for the quarter ending September 30. This substantial figure represents nearly 11% of Microsoft’s total quarterly revenue of $92.3 billion, underscoring the deep financial ties that persist between the two technology giants, even as their competitive landscape for customers intensifies.

Looking at broader financial trends, Microsoft’s revenue from OpenAI reached $24.1 billion for the full 2026 fiscal year. Based on the latest quarterly performance, the company is on track to generate an estimated $40 billion annually from its OpenAI-related agreements. Additionally, Microsoft noted $7.2 billion in outstanding receivables from OpenAI at the close of September, an increase from $6 billion at the end of June. These receivables represent amounts owed for prior transactions, distinct from new revenue.

The revenue streams for Microsoft from OpenAI are understood to encompass both revenue-sharing payments and the provision of Azure cloud computing services. While the exact breakdown remains undisclosed, reports have indicated that OpenAI shares a portion of its revenue with Microsoft, potentially around 20%, as part of a prior investment deal exceeding $13 billion. An agreement from April 2026 stipulates that OpenAI will continue these revenue-sharing arrangements with Microsoft through 2030, subject to a cap, even as OpenAI gains the flexibility to collaborate with competing cloud providers.

The partnership’s structure has seen notable shifts, particularly in October 2025, when Microsoft adjusted its exclusive hold on OpenAI, granting the startup greater autonomy to engage with other cloud service providers. In return for this increased freedom, OpenAI committed to purchasing an additional $250 billion in Azure services. Concurrently, Microsoft’s ownership stake in OpenAI has experienced a gradual reduction, declining slightly from approximately 25% in June to 24% in September, continuing a trend observed since a recapitalization in October 2025.
