Musk Lawyers Question OpenAI Co-Founder Brockman on Finances in Trial

A federal trial between Elon Musk and OpenAI entered its second week on Monday with Musk’s lawyers questioning company president and co-founder Greg Brockman about his personal finances. According to court proceedings detailed in multiple reports, the lawyers asked Brockman to explain how he came to be worth an estimated $30 billion.

The questioning focused on Brockman’s compensation and equity arrangements with OpenAI. Sources familiar with the testimony described portions of the exchange as lighthearted, including Brockman’s reference to keeping a diary, though this detail was unrelated to the financial lines of inquiry.

Brockman’s testimony occurred as part of Musk’s lawsuit against OpenAI, which centers on claims that the organization deviated from its founding commitments. The original nonprofit structure of OpenAI was established with a mission focused on safe artificial intelligence development rather than profit maximization.

Court records referenced during the trial include details of Brockman’s transition from the nonprofit to for-profit structures at the company.

No witnesses or filings introduced during Monday’s session produced public contradictions regarding the core financial questions posed to Brockman. Coverage from The New York Times, The Wall Street Journal, and technology reporter Alex Heath aligned on the sequence of events, with the financial scrutiny of Brockman forming the day’s primary focus in open court.
