Musk Takes the Stand: A Friendship on Trial
In a San Francisco courtroom on Tuesday, Elon Musk did something he has never done before: he told the story of his friendship with Sam Altman under oath. The testimony, delivered on the first day of his high-stakes trial against OpenAI, marks a dramatic escalation in one of the tech world's most bitter personal and professional feuds.
Musk's account—of how he and Altman bonded over a shared fear that artificial intelligence could destroy humanity, and how they founded OpenAI in 2015 as a nonprofit bulwark against that threat—is familiar to anyone who has followed his public statements. He has told it in interviews and to author Walter Isaacson for his bestselling biography. But Tuesday was the first time he said it under oath, according to TechCrunch.
Background: The Founding of OpenAI and a Fractured Partnership
The trial, which began on April 27, 2026, is the culmination of a legal battle Musk initiated in early 2024. Musk alleges that OpenAI, which he co-founded and initially funded with $100 million, has abandoned its original nonprofit mission to develop artificial general intelligence (AGI) for the benefit of all humanity. Instead, he claims, the company has become a for-profit entity controlled by Microsoft, prioritizing profit over safety.
Musk's testimony painted a picture of a close friendship that soured as OpenAI's direction shifted. He described late-night conversations with Altman about the existential risks of AI and their shared vision for a counterweight to Google's dominance in the field.

The relationship began to fray, Musk testified, when OpenAI started moving toward a for-profit structure in 2018. Musk left the company's board that year, citing conflicts of interest with Tesla's own AI development. Since then, he has founded xAI, a direct competitor to OpenAI, and has been one of the company's most vocal critics.
Key Developments: What Musk Said Under Oath
During his testimony, Musk recounted specific conversations and events that he says demonstrate Altman's betrayal of their original agreement. He described a pivotal meeting in 2015 where Altman convinced him to commit significant funding to OpenAI, promising that the organization would remain a nonprofit dedicated to open research.
"He told me that this was the most important thing we could do for humanity," Musk said, according to court transcripts cited by multiple outlets. "I believed him."
Musk also detailed his growing frustration as OpenAI began licensing its technology to Microsoft and eventually restructured into a "capped-profit" model. He argued that this transformation was a direct violation of the founding principles and that Altman had misled him about the company's long-term intentions.
The testimony was notably emotional at times, with Musk describing his sense of personal betrayal. "This wasn't just a business disagreement," he said. "This was about a friend who I trusted to do the right thing."
Expert Analysis: Implications for AI Governance
Legal experts say the trial could set a significant precedent for how AI companies are governed and how founders' original intentions are weighed against corporate evolution. "This case is fundamentally about whether a promise made in 2015 can be enforced in 2026," said Professor Sarah Chen, a technology law specialist at Stanford University, in an interview. "The court is being asked to decide if OpenAI's transformation was a natural evolution or a breach of trust."
The implications extend far beyond Musk and Altman's personal feud. A ruling against OpenAI could force the company to restructure or even return to its nonprofit roots, potentially disrupting the entire AI industry. Microsoft, which has invested billions in OpenAI, is watching the case closely, as its access to OpenAI's technology could be affected.
Industry observers note that Musk's testimony, while compelling, faces significant legal hurdles. OpenAI's lawyers are expected to argue that the company's shift was necessary to attract the talent and capital required to compete with tech giants like Google and that Musk himself benefited from the arrangement through his early involvement.
Multiple Perspectives: The Defense and Public Reaction
OpenAI's legal team has not yet presented its case, but pretrial filings indicate the company will argue that Musk's claims are a revisionist history designed to damage a competitor. They point to Musk's own for-profit AI ventures, including xAI, as evidence that his objections are motivated by business rivalry rather than principle.
Public reaction to the trial has been sharply divided. Supporters of Musk see him as a whistleblower exposing the dangers of unregulated AI development, while critics view the lawsuit as a publicity stunt from a billionaire seeking to undermine a successful rival. Social media platforms have been flooded with commentary, with the hashtag #OpenAITrial trending on X (formerly Twitter), which Musk owns.
TechCrunch reported that the courtroom was packed with journalists, legal analysts, and AI researchers, all eager to hear Musk's firsthand account. The trial is expected to last several weeks, with testimony from other key figures, including Altman himself and Microsoft CEO Satya Nadella.
What Happens Next: The Road Ahead
The trial is in its early stages, and the outcome remains uncertain. Musk's testimony will be followed by cross-examination from OpenAI's lawyers, who are expected to challenge his memory of events and his motivations. Altman is scheduled to testify later in the proceedings, which could provide a dramatically different account of their partnership.
Legal analysts predict that the case could ultimately be decided on narrow contractual grounds rather than broad questions of AI ethics. The key issue may be whether Musk can prove that OpenAI's founders had a legally binding agreement to maintain the nonprofit structure, or whether the company's evolution was a permissible business decision.
Regardless of the verdict, the trial has already achieved one thing: it has forced a public reckoning with the questions at the heart of AI development. Who controls the technology? What obligations do founders have to their original mission? And can friendship survive when billions of dollars and the future of humanity are at stake?
Conclusion: A Story That Matters Beyond the Courtroom
Elon Musk's testimony in the OpenAI trial is more than just a legal proceeding; it is a window into the messy, human reality behind one of the most consequential technological developments of our time. The story he told under oath—of friendship, ambition, and betrayal—is a cautionary tale about the challenges of governing powerful technologies in a world driven by profit and competition.
Whether the court rules in Musk's favor or not, the trial has already served as a powerful reminder that the future of AI will be shaped not just by algorithms and data, but by the relationships, promises, and conflicts of the people who build it. As the trial continues, the world will be watching to see whether justice—or just another chapter in a billionaire feud—prevails.
