Now she’s central to his courtroom fight More than two weeks into the trial in a federal courthouse in Oakland, California, neither of the tech titans has emerged as an overly sympathetic character. But nobody has more to lose than Altman. Musk previously testified that he started losing confidence in Altman and Brockman during the 2017 negotiations about OpenAI’s future. He was OpenAI’s biggest financial backer at the time, and thought his equity in its for-profit venture should reflect that. Musk testified that he gave OpenAI roughly $US38 million in the form of quarterly donations and rent payments for its office space – far less than the $US1 billion he initially pledged. Advertisement Altman told jurors on Tuesday that he contributed $US3.75 million to the non-profit when it first started, and then gave “a multiple of that” in equity interests he held to employees in its early days. Altman has repeatedly said he doesn’t currently have a direct equity stake in OpenAI. Altman said he and the other co-founders also devoted significant time and effort toward launching OpenAI, and he felt frustrated that those efforts were not reflected in Musk’s proposals for the equity split in the for-profit venture. Musk is seeking tens of billions of dollars in damages, and the unwinding of the ChatGPT maker’s for-profit conversion that was completed in October. He’s also pushing for Altman and Brockman to be removed from their leadership roles.
