Musk and Altman go to court

What's at stake for OpenAI, AI's future, and a combined $2 trillion in private market value.", "content": "<p>The most consequential legal battle in the history of artificial intelligence is now underway. On April 27, 2026, a nine-person jury was seated at a federal courthouse in Oakland, California, in the civil trial between Elon Musk and OpenAI CEO Sam Altman, with opening arguments scheduled for Tuesday, April 29. The case — years in the making — pits two of Silicon Valley's most powerful figures against each other over the soul, structure, and billions of dollars attached to one of the world's most valuable AI companies.</p>\n\n<p>At its core, the trial centers on whether OpenAI's transformation from a nonprofit into a for-profit enterprise betrayed the terms under which it was founded — and whether Musk, its earliest major financial backer, is owed anything for that transformation. OpenAI is currently valued at approximately $852 billion, according to court documents, and has nearly 1 billion weekly active users.</p>\n\n<h2>What the Musk vs. Altman Trial Is Actually About</h2>\n\n<p>Elon Musk co-founded OpenAI alongside Sam Altman and others in 2015 as a nonprofit dedicated to developing artificial intelligence for the benefit of humanity. Musk was the biggest individual financial backer in the company's early days, contributing more than $44 million to the startup, according to court documents. He left OpenAI's board in 2018 after failing to persuade its other leaders to merge OpenAI with Tesla or create a for-profit entity under his control, though he continued donating to the organization until 2020.</p>\n\n<p>OpenAI created a for-profit subsidiary in 2019. In October 2025, it completed a full transition to a public benefit corporation (PBC), with Microsoft receiving a 27% stake and OpenAI's nonprofit arm — the OpenAI Foundation — receiving a stake valued at $130 billion. The state attorneys general of California and Delaware approved the new corporate structure that same month, on a series of conditions.</p>\n\n<p>Musk filed his civil lawsuit in August 2024, alleging that Altman and OpenAI president Greg Brockman deceived him by abandoning the company's founding mission. Of the 26 claims Musk originally asserted, only two remain going into trial: <strong>unjust enrichment</strong> and <strong>breach of charitable trust</strong>. His lawyers dismissed fraud and constructive fraud claims ahead of trial to, in their words, streamline the case.</p>\n\n<p>Musk is seeking the removal of Altman and Brockman from their roles, a potential reversal of OpenAI's for-profit conversion, and the return of profits to OpenAI's nonprofit foundation. In January 2026, his lawyers stated he should receive up to $134 billion in alleged wrongful gains from OpenAI and Microsoft — though Musk has since asked to funnel any such funds back into the OpenAI charity rather than to himself.</p>\n\n<p>OpenAI has consistently denied all claims. It states that Musk donated $38 million to the nonprofit and that both OpenAI and Musk agreed in 2017 that a for-profit entity had to be part of the company's next phase. OpenAI also countersued Musk and his AI company, xAI, claiming they interfered in OpenAI's relationships with investors, customers, and employees.</p>\n\n<p>In February 2025, Musk offered to purchase OpenAI outright for $97.4 billion. Altman rejected the offer, countering — publicly — that he would buy X (formerly Twitter) for $9.74 billion.</p>\n\n<h2>Key Players, Trial Structure, and High-Profile Witnesses</h2>\n\n<p>U.S. District Judge Yvonne Gonzalez Rogers is presiding over the case and has opted to divide the trial into two parts: a liability phase and a remedies phase. She wants jurors to begin deliberations on the defendants' liability by May 12. The judge plans to give Musk and OpenAI each 22 hours to present their case in the liability phase, with Microsoft — named as a co-defendant and accused of aiding and abetting OpenAI's alleged breach of charitable trust — receiving 5 hours.</p>\n\n<p>The nine-person jury's verdict will be advisory and nonbinding. Judge Gonzalez Rogers will ultimately decide on any remedies. The jury selection pool was approximately three times larger than a typical civil case, due to concerns about finding impartial jurors given the celebrity status of both Musk and Altman. During jury selection, Judge Gonzalez Rogers noted plainly of Musk: <strong>"The reality is people don't like him."</strong></p>\n\n<p>Among those expected to testify are former OpenAI chief scientist Ilya Sutskever, former OpenAI CTO Mira Murati, and Microsoft CEO Satya Nadella, according to MIT Technology Review. Musk and Altman are both expected to take the stand — a prospect Altman appeared to relish. In a post on X in February 2026, Altman wrote: <em>"Really excited to get Elon under oath in a few months, Christmas in April!"</em></p>\n\n<p>Microsoft's position in this trial carries additional context. On the same day jury selection began — April 27 — Microsoft gave up its exclusive right to sell access to OpenAI's models, while remaining the AI giant's primary cloud provider, according to Axios. The timing underscored the rapidly shifting relationships at the center of this case.</p>\n\n<h2>Why This Trial Has Implications Far Beyond Two Tech Billionaires</h2>\n\n<p>The Musk vs. Altman trial arrives at a pivotal moment for both companies and for the AI industry broadly. SpaceX and OpenAI are combined valued at over $2 trillion on the private market. OpenAI recently closed a $122 billion funding round and is gearing up for a potential public offering expected later this year. Musk, meanwhile, is preparing to take SpaceX public in what is likely to be a record IPO. A prolonged, damaging trial — one that promises to expose years of internal communications, boardroom negotiations, and Silicon Valley deal-making — could affect both companies' trajectories toward public markets.</p>\n\n<p>The legal questions at the heart of the case are also genuinely unsettled. The trial will examine what happens when a nonprofit organization fundamentally changes its structure and mission — and what legal recourse, if any, early donors and board members have when that happens.</p>\n\n<p>The case has drawn enough public interest that, as of Sunday night before the trial began, approximately $390,000 in bets had been placed on prediction market Kalshi since mid-January, with the platform estimating Musk's chances of winning at 49.9%.</p>\n\n<h2>Expert and Analyst Reactions</h2>\n\n<p>The trial has drawn commentary from legal scholars, financial analysts, and technology journalists who view it as a defining moment for the AI industry and for corporate law.</p>\n\n<p>Wedbush analyst Dan Ives captured the spectacle bluntly: <em>"This is a tech soap opera that all investors will be watching as Musk vs Altman enters the MMA ring."</em></p>\n\n<p>Casey Newton, tech journalist and founder of the newsletter Platformer, framed the stakes more broadly: <em>"This is a clash of two enormous personalities in Elon Musk and Sam Altman. And I think what is at stake is potentially the future of OpenAI and the future development of all AI."</em></p>\n\n<p>Legal scholars have raised questions about the strength of Musk's remaining claims. Jill Horwitz, a law professor who studies nonprofit law at Northwestern University, said: <em>"The idea that Elon Musk can sue because he was a donor or used to be on the board is pretty puzzling."</em></p>\n\n<p>Jill Fisch, a professor of business law at the University of Pennsylvania Law School, pointed to the broader corporate governance questions the trial surfaces: <em>"I think there's a fundamental question about the extent to which corporations can change, can adjust to circumstances, can reinvent themselves."</em></p>\n\n<p>OpenAI, for its part, has been unambiguous in its position. In an official statement posted on X, the company said: <em>"We can't wait to make our case in court where both the truth and the law are on our side. This lawsuit has always been a baseless and jealous bid to derail a competitor."</em></p>\n\n<h2>What Happens Next</h2>\n\n<p>Opening arguments are scheduled for Tuesday, April 29. The liability phase of the trial is expected to run for approximately four weeks, with Judge Gonzalez Rogers targeting jury deliberations by May 12. If the jury finds in favor of Musk on either of the two remaining claims — unjust enrichment or breach of charitable trust — the case will proceed to a remedies phase, where the court will determine what, if anything, Musk is entitled to receive.</p>\n\n<p>The outcome could have significant consequences for OpenAI's planned public offering, its current corporate structure as a public benefit corporation, and the roles of Altman and Brockman at the company. It may also set legal precedent for how nonprofit-to-for-profit conversions are treated under charitable trust law — a question with implications well beyond the AI sector.</p>\n\n<p>Both sides have indicated they are prepared to fight. The weeks ahead are expected to bring a steady stream of internal documents, executive testimony, and revelations about the early days of one of the most consequential technology companies ever built.</p>\n\n<p>For more tech news, visit our <a href=\"/news\">news section</a>.</p>", "excerpt": "The civil trial between Elon Musk and OpenAI CEO Sam Altman officially began April 27, 2026, in Oakland, California, with opening arguments set for April 29.
