Musk v. Altman closing arguments wrap up, jury to deliberate Monday

Closing arguments concluded on Thursday in Elon Musk's lawsuit against OpenAI and co-founder Sam Altman, filed in a San Francisco federal court. Musk argues that OpenAI's shift away from its original non-profit structure breached agreements struck at the company's founding. OpenAI's attorneys called the complaint without merit.

The jury begins deliberations on Monday. The judge said at the start of the trial that the jury's verdict will be advisory, with the court issuing the binding ruling later. That structure could delay the practical impact of a case widely watched as a benchmark for the artificial intelligence industry.

Internal communications surfaced during the trial showed Microsoft's anxiety about over-reliance on OpenAI. The eventual ruling could reshape OpenAI's investor structure and the partnership models running through the sector. Other AI leaders, from Anthropic to Google DeepMind, are watching closely.
