Microsoft and OpenAI End Azure Exclusivity in Major Partnership Overhaul

Microsoft and OpenAI have restructured their partnership in a sweeping deal that ends Azure cloud exclusivity and removes the controversial "AGI clause" — a provision that had given Microsoft the right to determine whether OpenAI had achieved artificial general intelligence. The new terms were announced on April 27, 2026.

Under the revised agreement, Microsoft remains OpenAI's primary cloud partner and products will still ship first on Azure — but OpenAI can now serve customers across any cloud platform. This ends a years-long exclusivity arrangement that had tied OpenAI's infrastructure to Microsoft's ecosystem.

The AGI clause, which had enabled Microsoft to potentially walk away from its obligations if AGI was declared, has been eliminated. Revenue sharing is also restructured: Microsoft will no longer pay a share of revenue to OpenAI, while OpenAI's payments to Microsoft will be capped through 2030. Microsoft's IP license to OpenAI models continues through 2032, but is no longer exclusive.

Microsoft maintains its significant equity stake, valued at approximately $135 billion as of the October 2025 restructuring, representing about 27% of OpenAI on a diluted basis.

The deal marks a maturation of the relationship from a dependent startup-investor dynamic toward a more peer-level commercial partnership. It also positions OpenAI to pursue multi-cloud deals — a critical move as the company targets an IPO as soon as late 2026. Full details at Microsoft's official blog.
