Under the new structure, the OpenAI Foundation will own a 26% stake in the for-profit organization, with 47% owned by current and former employees and investors.

OpenAI holds a 32.5 percent for-profit stake on a converted basis, excluding recent funding rounds, the company said.

“The more successful OpenAI becomes as a company, the more valuable its equity stake will be that the nonprofit will use to fund its philanthropic efforts,” OpenAI said in a blog post.

The company announced plans to become a corporation in 2024. for-profit companyThis would take control away from the nonprofit and keep it as a separate arm. But facing pressure from civic leaders and former employees, OpenAI said in May that the nonprofit would retain control.
The OpenAI Foundation will make an initial $25 billion commitment to work to accelerate healthcare breakthroughs and technical solutions for AI resilience, OpenAI said Tuesday.
As part of the announcement, Microsoft said OpenAI had agreed to purchase an additional $250 billion worth of Azure services, but Microsoft would no longer have the right of first refusal to become OpenAI’s compute provider.
The companies also outlined some additional changes to their partnerships.
When Microsoft said OpenAI had achieved Artificial General Intelligence, or AGI, a term for an artificial intelligence system that rivals or surpasses human intelligence, it said that claim would need to be verified by an independent panel of experts. The revenue sharing agreement between the two companies will continue until that panel verifies the AGI.
Microsoft can now conduct AGI independently or in collaboration with third parties, and OpenAI can now develop some products in partnership with third parties.
OpenAI remains Microsoft’s leading model partner. Microsoft said its intellectual property rights for both models and products have been extended until 2032 and include post-AGI models. OpenAI’s consumer hardware is outside of Microsoft’s intellectual property.
“As we step into the next chapter of our partnership, both companies are better positioned than ever to continue building great products that meet real-world needs and create new opportunities for everyone, every business,” Microsoft said in a statement. he said.
Microsoft is scheduled to announce financial results for the first quarter of 2026 after market close on Wednesday.
