In a trial in California over the future control of OpenAI, Greg Brockman, OpenAI’s president, testifies about proposals made by Elon Musk. Brockman says Musk told him he deserved a majority stake in OpenAI and that Musk intended to use that control to build a self-sustaining city on Mars, including efforts to raise about $80 billion for the project. The testimony also reflects Musk’s position on corporate structure: Brockman says Musk supported transforming OpenAI into a for-profit company, while seeking full control or equivalent influence. Separate points described across reports include Musk’s allegation that OpenAI and CEO Sam Altman allegedly induced him to provide US$38 million to OpenAI’s nonprofit, and that he later saw the organization become a for-profit entity. The case is entering its second week, and the proceedings could affect how OpenAI is governed and whether any changes to its structure or control follow from the lawsuit. No ruling has been reported in the sources provided, and the dispute centers on competing accounts of Musk’s involvement, expectations, and influence over OpenAI’s direction.
