Microsoft (MSFT.O) and OpenAI have reached a landmark agreement allowing the ChatGPT creator to restructure as a public benefit corporation (PBC) — a move that values the company at $500 billion and grants it greater independence while keeping the two firms strategically aligned through 2032.
The deal marks one of the most significant moments in artificial intelligence business history, reshaping the governance of the world’s most influential AI developer. Microsoft will retain a 27% stake worth roughly $135 billion, securing a near tenfold return on its original $13.8 billion investment. The agreement maintains the companies’ long-term collaboration through a massive $250 billion Azure cloud contract, while ending Microsoft’s right of first refusal for future computing deals.
The new corporate structure — OpenAI Group PBC, controlled by the OpenAI Foundation — removes longstanding fundraising restrictions tied to their 2019 partnership. Those constraints had previously limited OpenAI’s ability to attract outside capital or secure diverse computing resources, even as its ChatGPT service exploded to over 700 million weekly users.
“This recapitalization simplifies OpenAI’s structure and gives the nonprofit a direct path to the resources it needs before artificial general intelligence (AGI) arrives,” said Bret Taylor, chair of the OpenAI Foundation. A new independent panel will be established to verify when OpenAI reaches AGI — the milestone where machines can reason and learn like human adults.
Analysts see the agreement as both a financial and structural turning point. “It resolves the longstanding conflict between OpenAI’s nonprofit mission and its for-profit operations,” said Gil Luria, head of tech research at DA Davidson. “This gives clarity to investors and regulators while positioning OpenAI for major capital inflows.”
Microsoft shares rose 2.5%, briefly lifting its market valuation above $4 trillion, underscoring investor optimism in its deepening AI dominance.
