Greg Brockman, OpenAI’s president and co-founder, testifies in Elon Musk’s lawsuit against OpenAI and CEO Sam Altman over the company’s shift from a nonprofit to a for-profit structure. In testimony reported across outlets, Brockman says his stake in OpenAI is worth nearly $30 billion, a figure that is raised as evidence of potential personal enrichment. Brockman also addresses claims tied to his writings, including references from a personal diary unsealed during discovery, and the court’s handling of specific text messages from Musk. A judge declines to admit a purported pretrial text in which Musk allegedly warns Brockman that he and Altman would be “the most hated men in America,” according to reporting.

Brockman further disputes Musk’s description of OpenAI’s early history and founding commitments. He says he never made commitments to Musk about OpenAI’s corporate structure and testifies that OpenAI remains governed by a nonprofit entity. He also recounts tensions during 2017-2018 discussions about potential governance and a for-profit arm, including alleged disagreements tied to control and Musk’s reaction to equity proposals. In later testimony, other former OpenAI figures describe concerns about Sam Altman’s management and board involvement, including how they learned about ChatGPT’s launch and why the board voted to remove Altman in 2023.
