Greg Brockman Defends $30 Billion OpenAI Stake During Musk Trial, Says He Poured 'Blood, Sweat, and Tears' Into Company

On Monday, OpenAI cofounder and president Greg Brockman testified that his equity stake at OpenAI is currently worth more than $20 billion, and perhaps up to $30 billion. Musk's attorney Steven Molo questioned why Brockman had not donated that wealth to OpenAI's nonprofit arm.

Brockman responded that he and others had invested 'blood, sweat, and tears' into building OpenAI since Musk left the company. He also testified that OpenAI's nonprofit foundation holds a stake of over $150 billion in the company, roughly five times his ownership interest.

Testimony revealed that Brockman has invested in several companies that signed major partnerships with OpenAI, including Cerebras, CoreWeave, and Helion Energy. Emails also showed that Brockman was initially paid with a $10 million stake in Sam Altman's family office, which he and Altman disclosed to Musk in 2017.
