Microsoft and OpenAI finalized an agreement allowing OpenAI to convert into a public benefit corporation, paving the way for a potential stock market listing. The restructuring values OpenAI at roughly $500 billion and grants Microsoft continued minority ownership while preserving governance independence. The revised model aims to balance profitability with ethical AI oversight, ensuring compliance with global regulations. Analysts said the transition could attract institutional investors seeking exposure to generative AI growth. The deal marks another milestone in formalizing commercial frameworks around frontier AI development.
