Elon Musk Testifies in Lawsuit Against OpenAI

A high-stakes trial has begun between Elon Musk and OpenAI CEO Sam Altman, with jury selection completed in California. During cross-examination, Musk expressed regret for funding OpenAI, alleging that the company betrayed him and its founding mission by shifting from a non-profit to a for-profit entity.

Elon Musk’s courtroom battle with Sam Altman is testing not just a contract, but the story Silicon Valley tells about whether world-changing AI can coexist with world-changing profits.

Conservative-leaning coverage emphasizes Musk’s narrative of betrayal and mission drift. The Washington Times frames the case as Musk “tell[ing] his side of OpenAI's beginnings” in a trial over promises to keep the lab “as a nonprofit dedicated to humanity's benefit.” The Washington Examiner similarly stresses that Musk accuses Altman of “prioritizing money over the organization’s humanitarian mission,” warning the outcome “could very well upend the technology industry’s AI race.” Another Washington Times piece underscores a storyline of “alleged betrayal, deceit and unbridled ambition” overshadowing the pair’s once-unified AI vision.

Liberal-leaning outlets, while covering the same facts, foreground skepticism about Musk’s motives and the theatrics of the trial. CBS News highlights his regretful claim that he was “a fool” for funding OpenAI and his charge that the company “betray[ed] him and the public” by going for-profit. But The Guardian notes OpenAI’s counter that Musk is “motivated by jealousy” and had agreed that a for-profit structure was necessary, accusing him of suing only after a failed bid to take over the company. A second Guardian report describes Musk’s testimony as a mix of grand claims that Altman “stole a charity” and judicial pushback, portraying him less as a selfless guardian of humanity and more as a combative, self-interested litigant.

On procedural details, perspectives largely converge. CBS and CNBC stress the “high-stakes” nature of a trial that could reshape OpenAI’s structure and leadership, noting a nine-person jury in Oakland and a split liability–remedies phase where the jury’s finding is only advisory.

Similarities and differences

Across the spectrum, outlets agree this is a defining clash over OpenAI’s founding mission and the future of the AI industry. Yet conservatives mostly echo Musk’s framing of a hijacked charity and lost altruism, while liberals foreground counter-evidence, personal rivalry, and the possibility that the “betrayal” is as much about power and ego as it is about principle.
