Opening arguments began today in the lawsuit that could determine how AI companies balance profit motives with promises of public benefit.
Sam Altman's lawyer stood before a San Francisco jury this morning and described a simple business disagreement: "Mr. Musk wanted control. When he couldn't get it, he left. Now he wants to rewrite history." Across the courtroom, Elon Musk's legal team painted a darker picture, a bait-and-switch that transformed a nonprofit dedicated to humanity's benefit into what they called Microsoft's R&D department.
The trial, which began with jury selection yesterday, arrives at a precarious moment for OpenAI. The company is reportedly preparing to go public even as it faces this challenge to its fundamental corporate structure. Musk seeks to unwind OpenAI's 2019 transition to a capped profit model, a move that could complicate or derail any IPO plans. According to CBS News, the case could also influence pending AI safety regulations as lawmakers watch to see whether courts will enforce founding promises about beneficial AI.
The dispute centers on conversations from 2015, when Musk says he committed over $44 million based on explicit promises that OpenAI would remain nonprofit and open-source. "I was swindled," Musk's filing states, according to The Guardian. He alleges Altman assured him the organization would put safety and broad access ahead of commercial interests.
OpenAI's transformation began in 2019 when it created a for-profit subsidiary, arguing it needed capital to compete with tech giants. That subsidiary now controls most operations while the nonprofit board maintains nominal oversight. Microsoft has invested $13 billion into the for-profit entity, gaining what Musk's team characterizes as effective control.
"This case is really about whether you can make promises to donors and then fundamentally alter the organization's mission," said Stanford Law professor Mark Lemley, who spoke to Al Jazeera about the trial's implications. "The outcome could affect how every AI research organization structures itself going forward."

The personal animosity between the former collaborators has intensified since Musk launched his competing AI company, xAI, in 2023. During pretrial depositions leaked to CBC News, Altman reportedly said Musk "wanted to be CEO or have majority control" of OpenAI before his 2018 departure. Musk's team counters that he left specifically because the organization was abandoning its founding principles.
This trial may expose the typically opaque world of AI research. The court has ordered both parties to produce internal communications from OpenAI's early days, including board meeting minutes and fundraising documents that could reveal how the industry's most influential company actually operates.
The timing matters. OpenAI is reportedly targeting an IPO within the next 18 months, which would require converting fully to a for-profit structure. A ruling that restricts this transition could force the company to choose between its IPO ambitions and its current corporate form.
Neither Musk nor Altman appeared in court today, though both are expected to testify. OpenAI declined to comment beyond its court filings, which argue that Musk is using the legal system to gain competitive advantage.
The judge has allocated three weeks for the trial, with testimony from early OpenAI employees and board members expected to begin tomorrow. Several former researchers who left to start their own AI safety organizations are listed as potential witnesses.
Video AI creators should watch whether the court distinguishes between open-source AI research and commercial deployment, a distinction that could affect model licensing. Any ruling on nonprofit governance could influence how research organizations structure partnerships with commercial entities. Discovery documents may reveal previously unknown details about training data sources and safety testing procedures. The case could establish precedent for whether founding documents create enforceable obligations to the public. A verdict against OpenAI might accelerate the trend of researchers leaving to start independent labs.
The trial continues tomorrow with testimony from OpenAI's former chief scientist Ilya Sutskever, who left the company last year to start his own AI safety venture. His perspective on the nonprofit's evolution could prove critical. He was present for both the founding conversations and the Microsoft partnership negotiations. Whether he sides with his former colleague or his former patron may determine which vision of OpenAI's origin story the jury believes.
