OpenAI and Microsoft on Monday announced a revamped partnership agreement that will allow the artificial intelligence company to cap revenue share payments and serve customers across any cloud provider.
As part of the new agreement, the companies said revenue share payments from OpenAI to Microsoft will be "subject to a total cap," but they will continue through 2030, "independent of OpenAI's technology progress." Microsoft will no longer pay a revenue share to OpenAI, according to a blog post.
The revenue sharing agreement between the two companies has existed for years. OpenAI will pay Microsoft at the same percentage, which is 20%, as part of the new deal, according to a source familiar with agreement who asked not to be named because the details are confidential.
OpenAI said Microsoft remains OpenAI's primary cloud provider, and that its products will ship first on Azure unless Microsoft decides otherwise. However, OpenAI can now serve "all of its products" to customers across any provider, including Microsoft rivals Amazon and Google .
Microsoft has been one of OpenAI's longtime backers, investing more than $13 billion in the company since 2019. The companies have continued to tout their relationship as core and strategic, but it's shown signs of strain in recent months as the partners move onto the other's turf. In a memo earlier this month, Denise Dresser, OpenAI's revenue chief, said the partnership has "limited our ability to meet enterprises where they are."
"Today, we are announcing an amended agreement to simplify our partnership and the way we work together, grounded in flexibility, certainty, and a focus on delivering the benefits of AI broadly," OpenAI said.
Shares of Microsoft are down roughly 1% on Monday.
The revamped partnership comes after Microsoft and OpenAI announced a series of changes to their agreement in October, when OpenAI completed a recapitalization. As part of that announcement, Microsoft said its investment for-profit arm was valued at $135 billion, or roughly 27% of the company on an as-converted diluted basis.
But in the months since, OpenAI has been looking to diversify its reach, striking multi-billion dollar deals with Microsoft competitors like Amazon.
