OpenAI, the company behind ChatGPT, has undergone a sweeping corporate restructuring that values it at $500 billion, transforming the former non-profit research lab into one of the world’s most valuable technology enterprises. The overhaul, announced on Tuesday, solidifies its partnership with Microsoft while giving the company greater flexibility to raise capital and expand commercially.
Under the new structure, OpenAI’s non-profit parent, the OpenAI Foundation, will retain control while holding equity in the for-profit arm. Microsoft will maintain a 27% stake in the company — now worth about $135 billion — and has extended its access to OpenAI’s technology until 2032, even if the company achieves artificial general intelligence (AGI), the point at which machines can match human cognitive abilities.
The new agreement also commits OpenAI to spending $250 billion on Microsoft’s Azure cloud services over the next several years, underscoring the deepening ties between the two firms. However, Microsoft will no longer hold the exclusive right of first refusal for OpenAI’s future cloud contracts, signaling the AI developer’s intent to diversify its partnerships as it scales.
The restructuring marks one of the most significant corporate transformations in Silicon Valley’s history — a shift from a non-profit research collective founded in 2015 to a global commercial powerhouse driving the AI revolution.
Microsoft shares rose 2% following the announcement, closing at $542.07 and lifting its market capitalization to $4.046 trillion, keeping it alongside Nvidia in the exclusive $4 trillion club. Apple, with a valuation just under $4 trillion, trails closely behind.
“The scale of the Azure commitment underscores Microsoft’s continued dominance in AI infrastructure,” said Barclays analyst Raimo Lenschow. “The deal also sets the stage for long-term collaboration between the two firms.”
Since the launch of ChatGPT in late 2022, OpenAI has become one of the fastest-growing technology companies in history, with over 800 million weekly active users and partnerships across sectors such as healthcare, education, finance and media.
Despite its explosive growth, OpenAI has yet to turn a profit. Analysts at HSBC estimate the company will record losses of $23.5 billion in 2025, rising to $60 billion by 2027, as it prioritises research and development over short-term earnings.
Chairman Bret Taylor said the restructuring “simplifies the company’s corporate structure,” giving the non-profit “a direct path to major resources before AGI arrives.”
Industry analysts say the overhaul resolves longstanding questions over OpenAI’s governance and its relationship with Microsoft. “It provides clarity on ownership rights and the path for future fundraising,” said Gil Luria, head of technology research at DA Davidson.
The announcement comes amid a global AI investment surge that has driven the valuations of major tech players to record highs. Meanwhile, PayPal revealed a new partnership allowing ChatGPT users to make purchases directly through its platform — lifting its shares nearly 4% to $73.02 and signaling renewed investor optimism in the digital economy.
For OpenAI, the restructuring marks the start of a new era — from an idealistic lab devoted to “safe and accessible” AI to a half-trillion-dollar company shaping the future of technology, markets, and work worldwide.
