Microsoft Deepens $135B Stake as OpenAI Becomes Public-Benefit Corporation
Key Takeaways: Microsoft–OpenAI Partnership Evolves
OpenAI has transitioned its for-profit subsidiary into a public-benefit corporation (PBC), marking a major shift in its corporate structure.
Microsoft now holds an approximately $135 billion stake, representing 27% ownership on an as-converted diluted basis.
The new agreement extends Microsoft’s exclusive IP rights through 2032 and redefines collaboration terms for future Artificial General Intelligence (AGI) development.
OpenAI’s nonprofit parent becomes the OpenAI Foundation, which will commit $25 billion to healthcare and AI resilience initiatives.
The partnership refines independence for both organizations, enabling OpenAI to work with third parties and Microsoft to pursue AGI development independently.
Strategic Agreement Strengthens Long-Term Collaboration
Since their initial 2019 partnership, Microsoft and OpenAI have pursued a shared goal of advancing Artificial Intelligence (AI) responsibly and making it broadly accessible. The companies have now entered a new definitive agreement that strengthens this alliance, setting the stage for continued innovation and long-term success.
Under the new structure, Microsoft supports OpenAI’s formation of a public-benefit corporation and recapitalization, holding an investment valued at approximately $135 billion. The ownership represents roughly 27% of OpenAI Group PBC on an as-converted diluted basis, including employees, investors, and the OpenAI Foundation. Before the recapitalization, Microsoft’s ownership stake in OpenAI’s for-profit subsidiary was approximately 32.5% on a fully diluted basis, excluding the effects of the company’s more recent funding rounds.
This change follows a year of negotiations involving state regulators and investors over OpenAI’s nonprofit status. The conversion resolves those concerns, allowing OpenAI to raise new funding, attract talent, and potentially pave the way for an initial public offering (IPO). The new structure follows nearly a year of discussions with the attorneys general of California and Delaware, whose offices oversee nonprofit governance. OpenAI revised elements of its corporate plan in response to those talks, resolving earlier concerns about its conversion to a public-benefit corporation.
Expanded IP Rights and Clarified AGI Provisions
The renewed partnership keeps the pillars that made the collaboration successful: OpenAI remains Microsoft’s frontier model partner, and Microsoft retains exclusive intellectual property (IP) rights and Azure API exclusivity until the arrival of Artificial General Intelligence (AGI).
At the same time, both companies have introduced a series of new guidelines designed to give each more flexibility for independent innovation while maintaining accountability and shared safety oversight.
Key provisions include:
Independent AGI verification: Any formal declaration of AGI by OpenAI will require review and confirmation by an independent panel of experts, ensuring transparency and shared confidence in such a milestone.
Extended IP timeline: Microsoft’s IP rights covering both models and products now extend through 2032, including any systems developed after AGI is achieved, with additional safety measures in place.
Defined research IP rights: Microsoft’s research-related IP—referring to the confidential methodologies and technical processes used in model development—will stay in effect until either 2030 or until AGI verification, whichever comes first.
Clear scope of research IP: These research rights apply only to internal or experimental models. They do not cover elements such as model architecture, training weights, inference or fine-tuning code, or data-center infrastructure. Microsoft retains non-research IP rights over those components.
Exclusion of consumer hardware: Microsoft’s IP rights no longer extend to OpenAI’s physical consumer hardware products, signaling OpenAI’s growing autonomy in that domain.
Third-party collaborations: OpenAI may now develop select products with external partners. Products that rely on APIs will remain exclusive to Microsoft Azure, while non-API-based offerings can be deployed through other cloud providers.
Independent AGI development: Microsoft can now pursue AGI independently or in partnership with other organizations, reflecting a broader approach to AI advancement.
Compute safeguards: Should Microsoft build AGI using OpenAI’s IP before AGI is formally recognized, those systems will be required to operate within strict compute limits, set far above the capacity of today’s largest training systems, to ensure transparency and responsible resource use.
Revenue-sharing adjustments: The existing revenue-sharing agreement between the two companies will remain active until AGI verification, though payments will be spread over an extended timeline.
Expanded Azure commitments: OpenAI has agreed to purchase an additional $250 billion in Azure cloud services, but Microsoft no longer holds a right of first refusal to be OpenAI’s exclusive compute provider.
Access for U.S. national security clients: OpenAI can now offer API access to U.S. government national security agencies, regardless of which cloud platform they use.
Open-weight model releases: OpenAI is also permitted to release open-weight models, provided they meet predefined capability and safety requirements.
Together, these updates give both companies greater independence and clarity while reinforcing their long-term alignment on safety, transparency, and innovation at the frontier of AI development.
Broader Industry and Market Context
The structural transition has wider implications for the technology industry and investors. The move pushed Microsoft’s valuation above $4 trillion, reflecting strong investor confidence in its AI trajectory. Shares rose roughly 2% on Tuesday as the market reacted to the announcement.
Analysts view this as a natural evolution. According to the Wall Street Journal’s report, “When Microsoft made some of the initial investments, you had no clue just how large and powerful OpenAI was going to be in the software and AI ecosystem,” said Jackson E. Ader, analyst at KeyBanc Capital Markets. “OpenAI wanted to spread its wings eventually. It was natural.”
The new structure also caps years of complex negotiations and internal challenges. OpenAI faced scrutiny following the 2023 firing and reinstatement of CEO Sam Altman, as well as litigation from Elon Musk’s xAI and other critics alleging mission drift from its nonprofit origins.
Meanwhile, Microsoft CEO Satya Nadella emphasized the company’s broader vision of being a platform-driven AI leader. In a recent interview, Nadella said:
“My mindset is all platform. I’m happy with OpenAI. I would love to have Anthropic, [Microsoft AI], Grok—anyone. If Google wants to put Gemini on Azure, please do so.”
Microsoft continues to expand its AI footprint by developing its own models, integrating OpenAI and Anthropic technologies into Microsoft 365 tools, and investing heavily in AI infrastructure. Nadella has recently shifted more of his focus to technical initiatives and data-center expansion.
