Microsoft and OpenAI Amend Their Partnership, Ending Exclusivity
Microsoft's license to OpenAI's models and products becomes non-exclusive through 2032 and OpenAI may sell on any cloud, while OpenAI's revenue-share payments to Microsoft continue through 2030 under a total cap and Microsoft stops paying one back.
- On 27 April 2026 Microsoft and OpenAI announced an amended agreement to "simplify our partnership and the way we work together"[1][2].
- Microsoft remains OpenAI's primary cloud partner and OpenAI products ship first on Azure unless Microsoft cannot and chooses not to support them, but OpenAI can now serve all its products to customers across any cloud provider[1][2].
- Microsoft keeps a license to OpenAI IP for models and products through 2032, now non-exclusive[1][3].
- Microsoft stops paying a revenue share to OpenAI; OpenAI's payments to Microsoft continue through 2030 at the same percentage, independent of OpenAI's technology progress, but subject to a total cap[1][3].
- Microsoft no longer has to decide its response if OpenAI finds it has reached artificial general intelligence[3].
- The change settles the clash over OpenAI's February deal with Amazon, which is investing up to $50 billion and was promised AWS exclusivity for OpenAI's Frontier agent platform; Amazon CEO Andy Jassy said OpenAI's models would come to AWS Bedrock[3][4].
- Microsoft stays a major shareholder, holding about 27% of OpenAI's for-profit arm, a stake valued at $135 billion when OpenAI recapitalised in October 2025 and committed to $250 billion of Azure spending[3][4].
