A 2017 journal entry asking “what will take me to $1B?” has become a central exhibit in the battle for the soul of the world’s most valuable AI company.
A 2017 journal entry asking “what will take me to $1B?” has become a central exhibit in the battle for the soul of the world’s most valuable AI company.

The personal fortune of OpenAI President Greg Brockman has swelled to nearly $30 billion, a figure revealed in a California courtroom that strikes at the heart of Elon Musk’s lawsuit alleging the firm abandoned its non-profit mission for immense personal gain. Brockman, a co-founder, has never invested his own capital into the company.
"He's speaking as the director and officer of a nonprofit, a publicly subsidized nonprofit, and he's writing secretly, 'How do I get to $1 billion?'" Marc Toberoff, an attorney for Musk, said, highlighting the focus of their cross-examination.
Brockman confirmed on the stand that his equity, granted when OpenAI formed a for-profit arm in 2019, is now valued near $30 billion. This stands in contrast to a 2017 journal entry where he pondered how to reach a $1 billion valuation for himself. Musk, who co-founded OpenAI, claims he donated roughly $45 million based on its original non-profit charter, while the company’s latest valuation has soared to $852 billion.
The trial scrutinizes the foundational ethics of a company central to the global economy, with major implications for its key partner, Microsoft, which holds a 27% stake. The outcome could reshape the competitive landscape for artificial intelligence, where Musk’s own xAI is a direct rival, and influence how future AI ventures are structured and governed.
Adding to the drama, court filings revealed text messages from Musk to Brockman just two days before the trial began. After a brief discussion about a settlement fell apart, Musk wrote, "By the end of this week, you and Sam will be the most hated men in America. If you insist, so it will be." Attorneys for OpenAI argued the message showed Musk's true motivation was to attack a competitor, but the judge ruled the texts inadmissible as evidence for the jury.
In his testimony, Brockman defended his wealth and the company's direction. He argued the value was not a windfall but the result of "years of hard work" by the team that remained after Musk’s departure. He testified that OpenAI's non-profit foundation now holds a stake worth over $130 billion, making it the "most well-resourced nonprofit in history." Brockman also noted that when Musk left OpenAI's board, he had threatened to build a competing AI lab within Tesla, a for-profit venture to which Musk never applied the same non-profit standards he demanded of OpenAI. The court also heard that Brockman held investments in several companies with significant OpenAI partnerships, including Cerebras and CoreWeave, a potential conflict of interest that had not been previously scrutinized.
The revelations from the trial introduce significant uncertainty for OpenAI's future, including a potential IPO. For investors in partners like Microsoft, the trial raises questions about the stability and governance of its key AI investment. A verdict against Altman and Brockman could force a restructuring of OpenAI or a massive financial judgment, potentially hobbling the current AI market leader and providing an opening for competitors like Google, Anthropic, and Musk's xAI. The trial continues with Brockman expected back on the stand, and CEO Sam Altman slated to testify later this month.
