Both companies announced the revised agreement in a joint statement on Monday. Microsoft retains a non-exclusive licence to OpenAI’s intellectual property through 2032, remains the primary cloud partner, and keeps its 27% equity stake.
OpenAI will continue paying Microsoft a revenue share through 2030, capped at a total amount. Microsoft shares fell ~3% on the news; Amazon and Alphabet gained slightly.
Microsoft and OpenAI announced on Monday that they have amended their partnership agreement in a restructuring that ends Microsoft’s exclusive right to sell OpenAI’s artificial intelligence models and products.
Under the revised terms, Microsoft will retain a licence to OpenAI’s intellectual property for models and products through 2032, but that licence will now be non-exclusive.
OpenAI may now sell its products and serve customers across any cloud provider, not only Microsoft Azure. In exchange, Microsoft will no longer pay a revenue share to OpenAI on the products it resells.
Revenue share payments running in the other direction, from OpenAI to Microsoft, will continue through 2030, independent of OpenAI’s technology progress, at the same percentage but subject to a total cap.
Microsoft remains OpenAI’s primary cloud partner, and OpenAI products will continue to ship first on Azure unless Microsoft cannot or chooses not to support the necessary capabilities.
The market read the agreement as a net negative for Microsoft and a net positive for its cloud rivals. Microsoft shares fell approximately 3% on Monday following the announcement. Amazon and Alphabet each gained slightly.
The logic is straightforward: Microsoft’s exclusive distribution rights were a structural competitive advantage in the cloud market that is now being surrendered.
Azure had, until today, been the only public cloud on which OpenAI’s most capable models were natively available, giving Microsoft a differentiation that drove enterprise Azure adoption at the height of the AI arms race in 2023 and 2024.
The removal of exclusivity means AWS, Google Cloud, and Oracle Cloud can now offer OpenAI models directly to their customers, levelling the competitive landscape.
For OpenAI, the logic runs in the opposite direction. The company’s ability to strike deals with Microsoft’s competitors has been constrained since its founding partnership was established.
In February 2026, Amazon and OpenAI announced a major strategic partnership in which Amazon agreed to invest up to $50 billion in OpenAI and AWS will serve as the exclusive third-party cloud distribution provider for OpenAI’s enterprise platform Frontier.
OpenAI separately expanded its existing $38 billion AWS agreement by $100 billion over eight years. That announcement, which came while the exclusive Microsoft agreement was still nominally in place, raised the question of how OpenAI would navigate the apparent tension.
Monday’s restructuring is the answer: by renegotiating the Microsoft exclusivity away, OpenAI has given itself the contractual freedom to honour the Amazon commitment and to pursue further cloud distribution partnerships without restriction.
The restructuring also removes one of the most legally unusual provisions in the original partnership: the AGI clause. Under the prior agreement, Microsoft was required to determine whether OpenAI had reached artificial general intelligence, a term for an AI system that rivals or exceeds human intelligence across a wide range of tasks, as a trigger for a change in the terms of the relationship.
That clause reflected the theoretical possibility, important to OpenAI’s nonprofit mission, that the moment of AGI arrival would require a different governance arrangement.
The amended agreement, removes this clause entirely, simplifying the legal relationship and removing an asymmetric interpretive power from Microsoft that OpenAI may have found uncomfortable as the company has grown in commercial scale and strategic independence.
The background to Monday’s announcement is a six-month negotiation. In October 2025, when OpenAI completed its recapitalization as a public benefit corporation and Microsoft converted its investment at a valuation of $135 billion (representing approximately 27% of the company on a diluted basis), the two companies also committed OpenAI to spending $250 billion on Microsoft Azure cloud services.
That commitment, and the revenue share arrangements associated with it, were the financial architecture of the original partnership. The Monday restructuring simplifies that architecture: Microsoft retains its equity position, its primary cloud status, and OpenAI’s revenue share through 2030, but gives up the exclusivity and the obligation to pay its own revenue share.
The net financial effect for Microsoft will depend on the relative size of the revenue share it was paying versus the revenue share it will continue to receive, figures that neither company has disclosed.
The trial context is directly relevant. The Musk v. Altman case, which began jury selection on the same day, centres partly on the question of whether Microsoft aided and abetted OpenAI’s breach of its nonprofit charter by facilitating the for-profit conversion.
Monday’s restructuring, which further simplifies and commercialises the Microsoft-OpenAI relationship, is not directly at issue in the trial but provides contextual evidence of the direction in which the relationship has been evolving since Musk left the board.
For investors and enterprise customers, the more immediate question is whether the removal of exclusivity will materially change the competitive position of Azure vs AWS and Google Cloud for AI workloads, and the ~3% Microsoft share price decline suggests the market has answered that in the affirmative, at least for now.
