In a moment that has paralyzed the tech industry, OpenAI CEO Sam Altman took the witness stand on Tuesday, May 12, 2026, in a federal courthouse in Oakland, California. Testifying in a landmark civil trial, Altman faced intense cross-examination over allegations that he “swindled” co-founder Elon Musk and betrayed OpenAI’s original non-profit mission. The trial, which centers on claims of breach of charitable trust and unjust enrichment, has become a high-stakes referendum on the governance of AGI (Artificial General Intelligence) and the future of Silicon Valley’s most valuable startup.
Altman’s testimony began with a direct confrontation of Musk’s most explosive claim: that he and Greg Brockman “stole” a charity to build a for-profit powerhouse now valued at nearly $1 trillion. When asked by his own counsel for his response to the accusation, Altman appeared exasperated. “It feels difficult to even wrap my head around that framing,” he told the jury. “We created one of the largest charities in the world. This foundation is doing incredible work and will do much more.”
Altman spent the morning hours detailing the “existential threat” the company faced in its early years. He argued that the non-profit model was a financial bottleneck that would have guaranteed OpenAI’s failure against rivals like Google. The transition to a “capped-profit” entity, he insisted, was the only way to secure the billions of dollars in compute power required to keep the mission of safe AGI alive.
The “Martian Inheritance” Revelation
One of the most “hair-raising” moments of the testimony involved Altman’s description of Elon Musk’s desire for absolute control. Altman revealed a previously undisclosed 2017 conversation in which Musk mused about the long-term governance of the company. According to Altman, Musk suggested that if he were to pass away, “OpenAI should pass to my children” to ensure it stayed aligned with his vision for a multi-planetary civilization.
Altman used this anecdote to paint Musk as a “mercurial” figure who only supported the for-profit shift if he was the one at the helm. “Mr. Musk felt very strongly that if we were going to form a for-profit, he needed total control,” Altman testified, adding that he found the idea of a family-inherited AI “extremely uncomfortable” and contrary to the idea that AGI should benefit all of humanity.
A Culture Under “Chainsaw” Management
The CEO also took aim at Musk’s management style, alleging that the Tesla billionaire did “huge damage” to OpenAI’s culture before his departure in 2018. Altman described a “demotivating” environment where Musk allegedly demanded that researchers be “stack-ranked” by their accomplishments.
“He wanted us to take a chainsaw through the organization,” Altman said, echoing the aggressive cost-cutting tactics Musk famously used at Twitter (X) and his government efficiency initiatives. Altman argued that Musk’s “chainsaw” approach was antithetical to a high-level research lab, claiming it led to the departure of several key scientists who felt the organization had become a “meritocracy of fear” under Musk’s influence.
The Trust Test: A Combative Cross-Examination
The afternoon took a darker turn as Musk’s attorney, Steven Molo, began a blistering cross-examination designed to dismantle Altman’s reputation as a “truthful” leader. Molo opened with a simple, blunt question: “Are you a completely trustworthy person?”
“I believe I am an honest and trustworthy business person,” Altman replied cautiously. Molo then presented a “parade of witnesses” including former board members Helen Toner and Tasha McCauley who had previously testified about Altman’s “consistent pattern of lying” and “undermining executives.” The jury was reminded of the chaotic 2023 “blip” where the board fired Altman for being “not consistently candid.” Altman largely parried these questions with short responses, often stating he “did not recall” specific details of the private board meetings.
Memes and Microsoft: The 2018 Fallout
To counter the narrative that Musk was a betrayed visionary, Altman described a 2018 meeting where he allegedly kept Musk fully informed about the upcoming Microsoft partnership. According to Altman, Musk was in “good spirits” at the time and spent a significant portion of the meeting “showing us memes on his phone” rather than raising objections to the funding structure.
Altman used this testimony to frame Musk’s current lawsuit as “sour grapes”—a retroactive legal attack fueled by Musk’s regret at leaving OpenAI just before its valuation skyrocketed. “I felt like he had abandoned us,” Altman said, his voice lowering. “To have someone I respected so much… continue to publicly attack us has been extremely painful.”
Conclusion: A Trillion-Dollar Verdict
As of May 12, 2026, the trial is nearing its conclusion. The jury now holds the fate of OpenAI’s leadership in its hands. If Musk succeeds, he could potentially force Altman’s ouster and a massive redistribution of $134 billion back into the non-profit wing. If Altman prevails, the path is cleared for OpenAI’s historic $1 trillion IPO this fall.
In the digital arteries of Silicon Valley, this trial has exposed the fractured soul of the AI revolution. It is no longer just a debate over code and compute, but a battle over the character of the men who will decide the future of intelligence. For Sam Altman, the “most influential man in AI,” the verdict will determine if he remains the architect of the future or a cautionary tale of corporate ambition.
