Altman Testifies Musk Sought 90% Stake and Control of OpenAI in Early Days

The legal battle between Elon Musk and OpenAI intensified in federal court this week as OpenAI CEO Sam Altman rejected claims that the company betrayed its nonprofit mission, testifying instead that Musk had sought greater control and pushed for a for-profit structure during OpenAI’s formative years.

Altman told the court that Musk had once demanded a 90% stake in the company. Under questioning by Musk’s lawyer, Altman said he became “extremely uncomfortable” with the idea of giving Musk majority control.

The lawsuit, now in its third week, centers on OpenAI’s transformation from a not-for-profit research lab into a multibillion-dollar artificial intelligence company. Musk filed the case last year, accusing OpenAI of abandoning its original mission to develop AI for the benefit of humanity. He claims he contributed nearly $38 million to help create OpenAI, only to see the company later prioritize profits and commercial expansion.

Altman rejected those claims, adding that Musk himself had pushed for greater control during the company’s early years. He also denied allegations that he and OpenAI co-founder Greg Brockman had attempted to “steal a charity,” saying it was difficult to even understand that characterization. Altman expressed hope that OpenAI’s not-for-profit arm would continue to benefit as the company grows.

Musk is seeking approximately $150 billion in damages from OpenAI and Microsoft. He is also seeking the removal of both Altman and Brockman from their leadership roles.

The outcome of the trial could have major consequences for OpenAI’s future corporate structure and leadership.
