Elon Musk is taking OpenAI's founders to court, alleging that CEO Sam Altman and President Greg Brockman orchestrated a "bait and switch" by converting the nonprofit AI company into a for-profit entity that enriched themselves at the expense of his charitable contributions. The trial, now underway in Oakland, California, centers on whether the company's structural transformation violated the charitable mission Musk helped establish when he cofounded OpenAI in 2015 with Altman and Brockman (Source 1, 2).

Musk claims he invested at least $44 million in OpenAI's early years under the assumption it would remain a nonprofit dedicated to developing safe, open-source artificial intelligence for humanity's benefit. Instead, he argues, Altman and Brockman allowed the organization to evolve into a for-profit subsidiary approximately one year after Musk's 2018 departure, then further transformed it into a for-profit public benefit corporation in 2025, enriching themselves in the process. The lawsuit seeks to revert OpenAI to nonprofit status, remove Altman and Brockman from the board, and award approximately $130 billion in damages to OpenAI's nonprofit foundation.

What Led to the Breakdown Between Musk and OpenAI's Leadership?

The relationship between Musk and the OpenAI founders deteriorated over disagreements about the company's structure and control. Musk testified that he was willing to accept a for-profit subsidiary only if it remained subordinate to the nonprofit parent organization. "What you can't have is the for-profit become the main event, and that's what we have here," Musk told the court.

The conflict intensified when Microsoft announced a $10 billion investment in OpenAI's for-profit subsidiary in 2022, valuing that entity at $20 billion. Musk said this moment marked when he "lost trust in Altman" and grew concerned that "they were really trying to steal the charity". In response, Musk told Altman via text that the arrangement felt like "a bait and switch," to which Altman replied that OpenAI had offered Musk equity when establishing the for-profit structure, which Musk had declined at the time.

Musk left OpenAI's board in 2018 after an acrimonious power struggle, later founding his own artificial intelligence company, xAI, which now competes directly with OpenAI. OpenAI's legal team argues that Musk's lawsuit is motivated by "jealousy, regret for walking away from OpenAI and a desire to derail a competing AI company".

How Are the Two Sides Presenting Their Cases in Court?

Musk's legal strategy centers on establishing his foundational role in creating OpenAI and proving that Altman and Brockman knowingly betrayed the nonprofit mission. During his testimony, Musk emphasized his contributions to the company's inception.

"I came up with the idea, the name, recruited the key people, taught them everything I know, providing the initial funding," Musk stated.

Musk also explained his original motivation for founding OpenAI, saying he was inspired by concerns about artificial intelligence's potential dangers. He noted that Google co-founder Larry Page had dismissed his safety concerns, calling him a "speciesist" for prioritizing human welfare over AI interests. This prompted Musk to create "some sort of counterpoint" to Google: "an open source nonprofit as opposed to a closed source for-profit".

OpenAI's legal team, led by attorney William Savitt, presents a starkly different narrative. Savitt argues that Musk himself proposed a for-profit structure but abandoned the company when he couldn't secure total control (Source 1, 3). The defense suggests that Musk's contributions were overstated, characterizing him as someone who "showed up every few weeks to give advice and occasionally yelled at people for not moving fast enough," while other cofounders contributed "sweat equity".

Savitt also highlighted inconsistencies between Musk's courtroom statements and his public social media posts, pressing him on whether he had actually proposed that OpenAI form a for-profit arm. Emails and meeting notes presented as evidence suggest Musk himself acknowledged that OpenAI needed a for-profit structure to compete effectively against Google.

What Evidence Is Central to the Trial?

Hundreds of pages of emails, text messages, call logs, and documents have been submitted as evidence, offering an inside view of the relationship between Musk and OpenAI's leadership before and after his departure. These communications often reveal stark contrasts between private exchanges and public statements made on social media.

• 2017 For-Profit Registration: Musk directed his family office head, Jared Birchall, to register a for-profit public benefit corporation in OpenAI's name, claiming he did so "in case it was needed" and that he needed to maintain control because he was "providing almost all the money".
• Funding Ultimatum: In emails presented to the court, Musk told the cofounders he would "no longer fund OpenAI until you make a firm commitment to stay nonprofit," later telling the court "I was a fool" for giving them "free funding to create a startup".
• 2023 Email Exchange: Altman told Musk he was his "hero" but expressed hurt over Musk's public attacks on OpenAI, to which Musk responded that "the fate of civilization is at stake".

How Could This Trial Reshape the AI Industry?

The outcome of this case carries enormous implications for the artificial intelligence landscape. OpenAI is planning what could be a blockbuster initial public offering (IPO) potentially within 2026, which would raise substantial capital to cement its position as a global AI leader. If Musk prevails, the court could force OpenAI to revert to nonprofit status, effectively dismantling the for-profit structure that has enabled its rapid growth and valuations.

Conversely, if OpenAI wins, Musk's xAI company faces a formidable competitor with significant financial resources and market dominance. The trial also raises broader questions about charitable giving in the United States. Musk has argued that losing the case would "give license to looting every charity in America," suggesting that a verdict against him could undermine protections for nonprofit organizations nationwide.

Steps to Understanding the Trial's Key Arguments

• Musk's Core Claim: OpenAI's leaders promised to keep the company nonprofit and open-source, then secretly converted it to a for-profit entity that enriched themselves while Musk's charitable contributions went unrewarded (Source 1, 2).
• OpenAI's Defense: Musk himself proposed the for-profit structure, left the company when he couldn't control it, and is now suing out of competitive jealousy toward his rival xAI company (Source 1, 2).
• The Judge's Role: Judge Yvonne Gonzalez Rogers will decide whether to grant Musk's remedies, including reverting OpenAI to nonprofit status, removing Altman and Brockman from the board, and awarding $130 billion in damages.

Judge Yvonne Gonzalez Rogers has made clear she intends to maintain strict order in her courtroom, scolding both sides for their social media posts about the trial before jury selection began. She warned Musk, Altman, and Brockman to "control your propensity to use social media to make things worse outside this courtroom". Musk agreed to limit his social media posts, though he had previously posted on his platform X that "Scam Altman and Greg Stockman stole a charity. Full stop".

The nine-person jury will advise Judge Rogers as she decides whether to grant Musk's requested remedies. Jury selection revealed that many potential jurors held negative views of Musk, with some calling him "greedy" and a "piece of garbage" in pre-questionnaire forms. Ultimately, jurors were selected based on their stated neutrality toward Musk and artificial intelligence.

As testimony continues, the trial will likely expose deeper tensions about how AI companies should be structured, who should benefit from their success, and whether nonprofit missions can survive the pressures of competitive markets and venture capital investment. The case represents one of the most significant legal challenges to an AI company's governance structure to date, with potential ramifications extending far beyond OpenAI itself (Source 1, 2, 3).
