Elon Musk’s lawsuit against OpenAI is set to go to trial on April 27, according to court scheduling.

The Tesla and xAI CEO accuses OpenAI of breaching its founding agreements by transforming from a nonprofit focused on safe artificial intelligence into a profit-driven company. Musk claims the restructuring into a capped-profit model and Microsoft’s involvement violate OpenAI’s original charter.

Court documents show the trial will run Monday through Friday, starting with jury selection on April 27. A pretrial conference remains scheduled for March 13 to resolve outstanding matters.
