Microsoft, OpenAI reach new deal valuing OpenAI at $500 billion

This might be an investment opportunity. Who will win the AI wars? It might be Microsoft and OpenAI. I would not bet against them.

“Microsoft and OpenAI on Tuesday said they had reached a deal to allow the ChatGPT maker to restructure itself into a public benefit corporation, valuing OpenAI at $500 billion and clearing the way for it to become a publicly traded company.

Microsoft would hold a stake of about $135 billion – or 27% – in OpenAI Group PBC, which will be controlled by the OpenAI Foundation, a nonprofit. The deal removes a major constraint on raising capital for OpenAI, which was founded as a nonprofit AI safety group and which signed a deal in 2019 with Microsoft that gave the Redmond, Washington-based firm rights over much of OpenAI’s work in exchange for providing the costly cloud computing services neede2d to carry it out.”
