Microsoft and OpenAI End Exclusive Cloud Partnership Agreement

On April 27, 2026, Microsoft and OpenAI announced an amended partnership agreement designed to reduce mutual dependencies and end Microsoft's role as the exclusive cloud distributor for OpenAI products. While Microsoft remains OpenAI's primary cloud partner and largest shareholder, the new terms grant OpenAI the independence to sell its models and services across rival platforms, including Google Cloud and Amazon Web Services (AWS). Under the agreement, new OpenAI products will still generally debut on Microsoft Azure first.

The restructuring follows a February conflict where OpenAI signed a $50 billion deal with Amazon for the exclusive distribution of its Frontier enterprise agent platform, an action that nearly prompted a lawsuit from Microsoft. To resolve this, Microsoft relinquished its exclusive intellectual property license through 2032 and agreed to the removal of the "AGI clause," which would have terminated Microsoft's access to the technology if artificial general intelligence were achieved.

Financial terms have shifted significantly. Microsoft will no longer pay OpenAI a revenue share for users accessing models through Azure. In return, OpenAI will continue paying Microsoft a 20% revenue share through 2030, though these payments are now subject to a total cap. OpenAI intends to use this expanded reach to reclaim enterprise market share from Anthropic. As part of its deal with Amazon, OpenAI must utilize two gigawatts of Amazon's Trainium accelerators to secure $35 billion in funding.
