Musk v. Altman Trial: Musk Says He Was Duped, Warns of AI Risks

The first week of the landmark Musk v. Altman trial has delivered dramatic testimony and revealed deep personal and strategic rifts between the founders of OpenAI. Elon Musk took the stand, claiming that he was deceived by OpenAI co-founders Sam Altman and Greg Brockman into providing early financial backing for the company. Musk testified that he was led to believe OpenAI would remain a nonprofit dedicated to open-source AI safety, only to watch it transform into a for-profit juggernaut. During his testimony, Musk issued stark warnings about the existential risks posed by artificial intelligence, stating that AI has the potential to "destroy humanity." He argued that the very technology he helped fund is now being developed in ways that prioritize profit over safety. In a surprising admission, Musk also revealed that his own AI company, xAI, has been distilling OpenAI's models—a process that involves training smaller models on the outputs of larger ones. This admission could complicate his legal position, as it suggests he is benefiting from the very technology he criticizes. The trial has already produced a trove of internal emails and text messages that paint a picture of broken trust and clashing visions. Early communications show Musk pushing for more aggressive development while Altman and Brockman advocated for a slower, more cautious approach. Later messages reveal escalating tensions as OpenAI shifted toward commercialization, culminating in Musk's departure and subsequent legal action. Legal experts say the case could have far-reaching implications for the governance of AI companies. If Musk prevails, it might force OpenAI to restructure or revisit its founding agreements. If Altman wins, it could validate the for-profit pivot that many AI startups are now pursuing. Regardless of the outcome, the trial has already exposed the raw nerves and high stakes behind the race to build artificial general intelligence. As the proceedings continue, the world is watching closely to see who—if anyone—will be held accountable for the path AI has taken.
