Microsoft and OpenAI have finalized a deal allowing the artificial intelligence firm to restructure as a public-benefit corporation, removing a key limitation that had restricted its ability to raise capital since 2019. The new structure values OpenAI at $500 billion and gives it more flexibility in managing its business operations.
A Shift in Control and Structure
Under the agreement, Microsoft will retain a 27% stake in OpenAI Group PBC, worth about $135 billion. The newly created public-benefit corporation will remain under the control of the OpenAI Foundation, a nonprofit organization. The deal simplifies OpenAI’s corporate structure and sets the stage for future expansion while maintaining oversight from the foundation.
OpenAI board chair Bret Taylor said the restructuring provides the nonprofit with a “direct path to major resources” ahead of reaching artificial general intelligence (AGI)—the point where AI systems can match human-level cognitive ability.
Longstanding Tensions Addressed
The changes ease previous tensions between Microsoft and OpenAI. In 2019, Microsoft agreed to provide essential cloud computing services in exchange for rights over OpenAI’s outputs. As ChatGPT surged in popularity, OpenAI’s computing needs outpaced expectations, and the earlier agreement limited its ability to raise outside funds or sign new partnerships.
With the new deal in place, Microsoft will no longer have exclusive rights to provide cloud services. Instead, OpenAI will purchase $250 billion worth of Microsoft Azure services. Microsoft has also agreed to forgo rights to any hardware developed by OpenAI, including assets from its acquisition of design firm io Products, previously led by former Apple design chief Jony Ive.
Investment Returns and Future Collaboration
Microsoft’s investment of $13.8 billion in OpenAI has now yielded a nearly tenfold return. Following the announcement, Microsoft shares rose by 2.5%, briefly lifting its market capitalization above $4 trillion.
The partnership is set to continue at least through 2032, ensuring Microsoft retains access to OpenAI’s AI models and products, including in the event OpenAI achieves AGI. An independent panel will be required to verify any such milestone.
Industry Response and Outlook
Analysts say the deal provides more clarity on ownership rights and future investment opportunities. DA Davidson’s head of tech research, Gil Luria, noted that the restructuring settles longstanding questions around OpenAI’s nonprofit origins and ownership claims by Microsoft.
At the same time, questions remain about OpenAI’s long-term governance, transparency, and ethical oversight. Adam Sarhan of 50 Park Investments said the simplified structure offers “a clearer path for innovation and accountability,” while recognizing the ongoing scrutiny around data use and safety.
The timing of the announcement coincided with Nvidia’s strategic investment in Nokia and came ahead of Microsoft CEO Satya Nadella’s scheduled address at the company’s developer event in Washington, DC, where AI collaborations are expected to be a central topic.
