OpenAI President Greg Brockman, also CEO Sam Altman’s top lieutenant, disclosed in court that his stake in the artificial intelligence company is worth nearly $30 billion. Brockman, who further testified that he did not personally invest any money in OpenAI, made this revelation during a civil trial in Oakland, California. This substantial disclosure would place Brockman on the Forbes list of the world’s richest people, with a wealth comparable to Melinda French Gates.

The trial centers on the company’s 2015 founding as a nonprofit startup, primarily funded by Elon Musk, before it evolved into a capitalistic venture now valued at $852 billion. The civil lawsuit accuses Altman and Brockman of double-crossing Musk by straying from the San Francisco company’s founding mission to be an altruistic steward of a revolutionary technology. Specifically, the lawsuit alleges that they shifted into a moneymaking mode behind Musk’s back, abandoning the initial commitment to altruism.

During the proceedings, OpenAI lawyers attempted to admit as evidence a text message exchange that occurred late Sunday, two days before the trial began. According to a court filing, Musk sent a message to Brockman to gauge interest in a settlement. Brockman replied that both sides should drop their respective claims. In response, Musk allegedly shot back, “By the end of this week, you and Sam will be the most hated men in America. If you insist, so it will be.” However, Judge Yvonne Gonzalez Rogers, overseeing the trial, did not admit this text exchange as evidence, maintaining a focus on the core allegations of the case.
