OAKLAND, United States — A high-stakes legal battle between two of Silicon Valley’s most influential figures has entered trial this week, as Elon Musk takes on Sam Altman and OpenAI in a case that could reshape the governance and future direction of artificial intelligence development.
The trial, beginning with jury selection at a federal courthouse in Oakland, stems from a 2024 lawsuit filed by Musk accusing OpenAI’s leadership of abandoning its original nonprofit mission and improperly transitioning into a profit-driven enterprise.
Musk, who co-founded OpenAI in 2015 alongside Altman and others, argues that the company was established with a commitment to developing artificial intelligence for the benefit of humanity, without commercial constraints.
Early mission statements from the organisation described its goal as advancing “digital intelligence … unconstrained by a need to generate financial return.”
At the centre of the dispute is Musk’s claim that Altman breached the founding agreement by restructuring OpenAI into a for-profit model and entering into major commercial partnerships, including with Microsoft.
Musk alleges that this shift represents a violation of the organisation’s original charitable intent.
OpenAI, however, rejects the allegations. The company argues that Musk was aware of and at times supportive of its evolving structure, and contends that his lawsuit is driven by dissatisfaction after leaving the organisation in 2018 following internal disagreements.
OpenAI has also dismissed the claims as part of what it describes as a long-running pattern of public criticism from Musk.
The lawsuit seeks sweeping remedies, including more than $134 billion in damages and structural changes that could potentially reverse OpenAI’s restructuring.
Musk has also called for the removal of Altman and OpenAI president Greg Brockman from leadership roles.
The case carries significant implications for the AI industry, with OpenAI reportedly preparing for a potential public listing that could value the company at around $1 trillion. Any disruption to its corporate structure could affect investor confidence across the sector.
Legal filings in the case have revealed extensive internal communications between the founders, highlighting early disagreements over control, funding, and the pace of AI development.
These documents are expected to play a central role in a trial projected to last two to three weeks.
A nine-person jury will hear claims of breach of contract and unjust enrichment, while key Silicon Valley figures, including executives from major tech firms, are expected to testify.
Beyond the legal arguments, the case underscores a long-running personal rivalry between Musk and Altman, who have frequently clashed in public over the direction of AI development.
Their dispute has intensified since the launch of ChatGPT in 2022, which propelled OpenAI to global prominence.
Court proceedings are expected to be closely watched by the tech industry, as the outcome could set a precedent on how nonprofit-founded technology companies evolve into commercially scaled enterprises in one of the most competitive sectors of the modern economy.
