Microsoft and OpenAI Seal $500 Billion Valuation Deal
Microsoft and OpenAI have reached a landmark agreement that restructures OpenAI into a public benefit corporation, valuing the AI firm at a staggering $500 billion. This deal grants OpenAI greater operational freedom while maintaining its deep ties with Microsoft.
Key Takeaways
- OpenAI is now valued at $500 billion as a public benefit corporation.
- Microsoft retains a 27% stake worth approximately $135 billion.
- The partnership is locked until at least 2032, covering cloud services and AI model rights.
- OpenAI commits to a $250 billion Azure cloud services purchase.
Resolving Longstanding Constraints
The new arrangement removes major fundraising constraints that have limited OpenAI since its 2019 agreement with Microsoft. As ChatGPT exploded to over 700 million weekly users, these limitations created significant tension between the partners.
Microsoft’s $13.8 billion investment in OpenAI has now generated nearly ten times returns, with the tech giant’s shares rising 2.5% following the announcement, pushing its market value back above $4 trillion.
AGI Provisions and Corporate Structure
The deal maintains the two companies’ interconnection until 2032 through a massive cloud computing contract. Microsoft retains certain rights to OpenAI products and AI models even if OpenAI achieves artificial general intelligence (AGI).
Bret Taylor, OpenAI Foundation’s board chair, stated: “OpenAI has completed its recapitalization, simplifying its corporate structure. The nonprofit remains in control of the for-profit, and now has a direct path to major resources before AGI arrives.”
The new agreement requires an independent panel to verify any claims of AGI achievement, addressing provisions from the previous 2019 arrangement.
Industry Reaction
Adam Sarhan, CEO of 50 Park Investments, commented: “OpenAI still faces ongoing scrutiny around transparency, data usage, and safety oversight. But overall, this structure should provide a clearer path forward for innovation and accountability.”
Gil Luria of DA Davidson added that the deal “resolves the longstanding issue of OpenAI being organized as a not-for-profit and settles the ownership rights of the technology vis-Ã -vis Microsoft. The new structure should provide more clarity on OpenAI’s investment path, thus facilitating further fundraising.”
Cloud Services and Hardware Rights
In a significant shift, Microsoft will no longer have right of first refusal for providing computing services to OpenAI. Instead, OpenAI has committed to purchasing $250 billion of Azure cloud computing services.
The agreement also clarifies that Microsoft will not have any rights to hardware produced by OpenAI. This comes after OpenAI’s $6.5 billion acquisition of Jony Ive’s startup io Products in March.
