OpenAI’s $500B Pivot: Completes Restructuring as Public Benefit Corp

On 29 October 2025, OpenAI announced the completion of its restructuring into a Public Benefit Corporation, with its former nonprofit becoming the OpenAI Foundation that will retain control over the for‑profit division and hold an estimated $130 billion in equity, according to Bret Taylor, Chairman of OpenAI’s Board of Directors. The move, described as a long‑anticipated step, has allowed the company to position itself for a potential public trading path by removing a major structural barrier, the article notes.

Microsoft, described as the largest investor, now owns 27% of the new PBC entity, a stake valued at roughly $135 billion, implying an extraordinary market valuation of $500 billion for OpenAI’s for‑profit arm. The restructuring followed a consent from Microsoft and included a framework for governance changes, with details such as IP rights and an independent panel to verify AGI attainment highlighted as part of the agreement.

Microsoft confirmed the revised ownership and pledged to spend up to $250 billion on Microsoft Azure, while the article points to tensions during drafting of a memorandum of understanding in September. The piece frames the restructuring as removing a major obstacle to OpenAI’s long‑term financial strategy and potential public listing.
