OpenAI Completes For-Profit Restructuring; Microsoft Secures 27% Stake at $500 Billion Valuation

OpenAI has officially completed its transition to a for-profit structure following regulatory approval of a major corporate reorganization. Originally founded in 2015 as a nonprofit AI research organization, the company has restructured its operational arm into a Public Benefit Corporation (PBC). This shift grants the maker of ChatGPT greater freedom to raise capital and operate with enhanced commercial flexibility, all while remaining under the oversight of its nonprofit parent, the OpenAI Foundation. Notably, as part of this transformation, Microsoft has acquired a 27% stake in the newly structured OpenAI—valued at approximately $135 billion—based on a total company valuation of around $500 billion. The OpenAI Foundation will retain 26% ownership, while the remaining 47% will be held by current and former employees along with other investors.

Under the revised agreement, Microsoft will maintain exclusive access to OpenAI’s technology and future models—including potential systems capable of achieving Artificial General Intelligence (AGI)—through 2032. This ensures Microsoft can continue integrating OpenAI’s tools into its ecosystem, such as Copilot in Microsoft 365 and its Azure AI services. In return, OpenAI has committed to utilizing roughly $250 billion worth of Microsoft Azure cloud services over the coming years. Unlike previous arrangements, however, OpenAI is now permitted to engage other cloud providers as well.

Regarding AGI—a central point of contention in recent negotiations between Microsoft and OpenAI—the new framework establishes clearer boundaries between the two entities. Microsoft may now pursue AGI research independently or with other partners, while OpenAI retains the right to collaborate with third parties on specific product development initiatives.

This reorganization formally ends the experimental “capped-profit” model introduced in 2019, which limited investor returns to align with the organization’s nonprofit mission. For Microsoft—which has invested approximately $13 billion in Sam Altman’s company since 2019—the new arrangement delivers both financial upside and strategic advantage. The deal reportedly gives Microsoft a significant equity position (~27%) in an AI firm targeting $125 billion in annual recurring revenue by 2029. Prior to this ownership realignment, Microsoft held a 32.5% stake in OpenAI. Additionally, the tech giant led by Satya Nadella has extended its exclusive access to OpenAI’s technology through 2032, prolonging an earlier agreement that was set to expire in 2030.

Meanwhile, OpenAI has announced that its foundation—holding equity valued at roughly $130 billion—will invest $25 billion to advance healthcare innovation and bolster AI safety and resilience. In related news, NVIDIA revealed last month its intention to invest up to $100 billion in OpenAI.
