OpenAI Breaks Free Of Microsoft, Expands AWS Partnership 04/29/2026 - MediaPost

OpenAI has restructured its partnership with Microsoft, ending the exclusive arrangement that gave Microsoft priority access to OpenAI's models. The change allows OpenAI to offer its services on other cloud platforms, including AWS and Google Cloud. Microsoft will no longer pay a revenue share to OpenAI for reselling its models.

The end of the revenue share means Microsoft no longer pays OpenAI a portion of the income from selling access to OpenAI's models. The terms of the original deal had given Microsoft exclusive cloud rights for OpenAI's models.

The restructuring reflects OpenAI's growth and desire for more independence from Microsoft. It also intensifies competition among cloud providers to offer leading AI models. Analysts suggest the move may benefit customers by providing more cloud options for deploying OpenAI's models, potentially putting pricing pressure on all three providers.
