OpenAI co-founder and president Greg Brockman took the witness stand on Monday and dropped a massive financial bombshell. During questioning in a California courtroom, Brockman revealed that his personal stake in the artificial intelligence company is worth nearly $30 billion. He also disclosed several deep, previously unknown financial ties to Sam Altman, OpenAI’s chief executive officer.
These shocking details emerged during a high-stakes trial initiated by Elon Musk. The billionaire entrepreneur co-founded OpenAI but left the organization years ago. Musk is now suing the company, arguing that the current leadership team illegally transformed the business from a nonprofit research lab into a profit-seeking juggernaut. He wants the court to force OpenAI to return to its original charitable goals.
Lawyers representing Musk used Brockman’s testimony to paint a picture of compromised leadership. The legal team suggested that massive financial incentives destroyed Brockman’s independence. They argued these secret deals led Brockman to blindly support Altman as he drove the controversial reinvention of OpenAI into a for-profit corporation.
The outcome of this trial, now entering its second week, could completely alter the future of the technology industry. OpenAI sparked a massive global craze for generative artificial intelligence when it launched ChatGPT in late 2022. Since that launch, the company has raised well over $100 billion from outside investors. Executives use that cash to hire top researchers, buy expensive computing power, and expand operations as they prepare for a potential initial public offering that could value the company at $1 trillion.
Musk wants to stop that process entirely. He is actively seeking the immediate removal of both Altman and Brockman from their leadership positions. Furthermore, the Tesla founder demands $150 billion in damages.
During his testimony, Brockman openly agreed with the lawyer’s estimate that his OpenAI shares are worth close to $30 billion. This specific figure surprised many people watching the trial, as the company previously kept executive compensation tightly under wraps.
The court then focused on a specific deal struck back in 2017. During that year, Altman gave Brockman a personal stake in Altman’s own family office. At the time, that stake was valued at $10 million. Interestingly, 2017 was the same year that Brockman, Musk, and other executives first started discussing how to restructure OpenAI. They debated turning the lab into a for-profit business so they could afford the incredibly pricey computer chips required to train new artificial intelligence systems.
Brockman admitted to the court that he never discussed this special compensation arrangement directly with Musk. However, Musk’s legal team read several private emails aloud in court. These messages showed that Altman actually mentioned the side deal during a separate conversation with Jared Birchall, the man who runs Musk’s family office.
Birchall quickly relayed the alarming details to his boss. In an email to Musk, Birchall wrote that Altman compensated Brockman on the side by giving him a percentage ownership of his personal family fund. Birchall warned Musk that this secret deal could mean Brockman would hold a much greater allegiance to Altman moving forward. After reading the warning, Musk forwarded Birchall’s note directly to Brockman and simply added two question marks.
When the lawyer pressed Brockman on the stand about whether this money bought his loyalty to Altman, Brockman deflected the accusation. He told the courtroom that he would not quite describe their relationship in those terms.
The financial entanglement between the two executives goes far beyond the family fund. On Monday, Brockman also disclosed that he owns personal shares in an artificial intelligence chip startup called Cerebras. He held these shares even while OpenAI executives actively discussed buying the chipmaker outright. Earlier this year, OpenAI announced it would spend a significant amount of money to purchase chips from Cerebras, a move that directly benefits Brockman’s personal investment portfolio.
Additionally, Brockman testified that he holds a financial stake in Helion Energy. This fusion power startup has already received hundreds of millions of dollars in investment money directly from Altman. The conflict of interest grew so severe that Altman stepped down from the Helion board of directors in March because OpenAI and Helion wanted to enter into business contracts together.
Musk, currently the richest person in the world, built his entire lawsuit around the idea of a broken promise. He alleges that OpenAI, Altman, and Brockman secured $38 million in early donations from him by promising to build a strict nonprofit. Musk claims he only offered his personal help because he believed the lab would prioritize the safe development of artificial intelligence for all of humanity. He accuses the executives of pivoting to a for-profit model simply to enrich themselves. His formal charges include a breach of charitable trust and unjust enrichment.
OpenAI firmly rejects these accusations and offers a different motive for the lawsuit. Lawyers for the startup argue that a desperate compulsion to control the artificial intelligence narrative drives Musk. They claim he feels deeply bitter about the massive success OpenAI achieved after he left its board of directors in 2018.
The defense team also pushed back on the safety narrative. OpenAI lawyers stated that Musk never prioritized safety issues while he worked with the company. They argue this entire lawsuit is just a ruthless business tactic designed to damage a rival. According to the defense, Musk simply wants to cripple OpenAI to bolster his own artificial intelligence company, a SpaceX unit called xAI, which currently lags far behind ChatGPT in total user adoption.
