Elon Musk v. OpenAI Trial: Testimony Reveals Bitter Battle for AI Control

The second week of the landmark legal battle between Elon Musk and OpenAI shifted the courtroom focus from the company’s founding ideals to the messy, often volatile personalities of the men who built it. While Musk spent the previous week framing himself as a betrayed philanthropist fighting to save AI for humanity, the narrative flipped this week as OpenAI’s leadership presented a different version of history—one where Musk was not a guardian of the nonprofit mission, but a founder who fought for absolute control.

At the center of the drama was Greg Brockman, OpenAI’s president, whose testimony aimed to dismantle Musk’s image as a selfless donor. Brockman described a pattern of behavior where Musk allegedly pushed for a for-profit transition the moment the company achieved technical success, suggesting that the current lawsuit is less about ethics and more about a founder who is disgruntled after losing the steering wheel.

The proceedings have evolved into a high-stakes autopsy of the relationship between Musk, Sam Altman and Brockman. With damages sought as high as $134 billion and the potential to unwind OpenAI’s corporate restructuring, the verdict could ripple through the entire AI industry, affecting valuations for both OpenAI and Musk’s own venture, xAI.

The ‘Haunted Mansion’ and the Battle for Equity

Much of this week’s testimony focused on the summer of 2017, a pivotal moment for the young company. Brockman recounted a celebration at Musk’s “Haunted Mansion” near San Francisco, held after an OpenAI model beat world-class players in the complex video game Dota 2. According to Brockman, the atmosphere was celebratory—complete with confetti and whiskey served by then-girlfriend Amber Heard—but the underlying conversation was about power.

Brockman testified that Musk viewed this technical milestone as a “triggering event” to move OpenAI toward a for-profit model. Over the following weeks, the cofounders engaged in intense negotiations to raise the massive capital required to achieve Artificial General Intelligence (AGI). However, these talks hit a wall over the issue of governance. Brockman alleged that Musk demanded majority equity, the right to appoint the majority of the board, and the role of CEO.

The tension peaked in August 2017 during a meeting where Ilya Sutskever, then OpenAI’s chief scientist, brought a painting of a Tesla as a gesture of goodwill. When Brockman and Sutskever proposed equal equity shares among the founders, Musk reportedly fell silent before declining the offer. Brockman testified that Musk then “stormed around the table,” grabbed the painting, and walked out of the room.

For Brockman, this was the “fork in the road.” He told the jury that the cofounders could not accept giving Musk unilateral control over AGI, leading to the eventual fracture that saw Musk leave the company in 2018.

Journal Entries and the Greed Narrative

Musk’s legal team, led by attorney Steven Molo, attempted to paint Brockman as a hypocrite motivated by financial gain. Molo pointed to the fact that while Brockman never personally invested money into OpenAI, he now holds a stake estimated at nearly $30 billion. To support this, Molo introduced Brockman’s private electronic journals from 2017, highlighting an entry where Brockman questioned what financial path would lead him to a $1 billion net worth.

The courtroom atmosphere grew tense as Molo questioned why Brockman didn’t donate such vast sums to the nonprofit mission he claimed to prioritize. Brockman pushed back, insisting that his primary motivation had always been the mission, even while navigating the financial realities of building the world’s most powerful AI.

The defense also raised concerns regarding potential conflicts of interest. Evidence was introduced showing that Altman and Brockman have stakes in several companies with business ties to OpenAI, including the cloud provider CoreWeave and the nuclear fusion startup Helion Energy. These revelations aim to suggest that OpenAI’s leadership has been operating a “closed loop” of investments and deals that contradict their original nonprofit pledge.

The Plot to Poach Sam Altman

Adding a new layer to the conflict, former OpenAI board member Shivon Zilis testified about Musk’s attempts to recruit the company’s top talent for his own interests. Zilis, who has a complex personal and professional history with Musk—including being the mother of four of his children—revealed that Musk had plotted to build a rival AI lab within Tesla.

According to Zilis, Musk concluded by late 2017 that OpenAI was unlikely to reach AGI and pivoted his focus toward Tesla. Internal documents and text messages revealed that Musk asked Andrej Karpathy to provide a “list of top OpenAI people to poach.” Most notably, Zilis testified that Musk tried to recruit Sam Altman himself to lead this prospective Tesla AI lab.

This testimony is central to OpenAI’s legal strategy: the argument that Musk is not suing to protect a nonprofit mission, but is attempting to undermine a competitor. By attempting to poach the very people he now claims “deceived” him, OpenAI argues that Musk’s motivations have always been about talent acquisition and competitive dominance.

The Trillion-Dollar Stakes

While the courtroom drama focuses on old emails and paintings, the financial implications are staggering. OpenAI is currently eyeing an IPO with a valuation approaching $1 trillion. A court order to unwind its restructuring or remove its top executives would throw that trajectory into chaos.

Conversely, Musk’s xAI has become a division of SpaceX. The combined entity is expected to go public as early as June, with a target valuation of $1.75 trillion. The trial is not just a dispute over a $38 million donation from years ago; it is a battle for the legitimacy and governance of the companies that will likely define the next century of computing.
