Elon Musk and OpenAI CEO Sam Altman head to trial on April 27

In short: Elon Musk’s lawsuit against OpenAI and CEO Sam Altman is set to go to trial in Oakland, California, starting April 27.

What happened

A federal trial is scheduled to begin April 27 in Oakland, California, in a case often described as Musk v. Altman. Musk helped start OpenAI, the company behind ChatGPT, but later left. Now he is suing OpenAI leaders Sam Altman and Greg Brockman.

Musk’s main claims are that OpenAI’s leaders broke duties tied to OpenAI’s nonprofit purpose, unfairly benefited at his expense, and committed fraud. In simple terms, he says he gave support based on promises that were not kept. Musk is asking for major changes, including removing Altman and Brockman from their roles and forcing OpenAI to change parts of how it is structured.

OpenAI argues that Musk has not shown a clear, legally enforceable promise, and that some of his claims should not be allowed. The case has already narrowed, with some claims dismissed earlier.

The trial may include testimony from well-known tech executives, including Microsoft CEO Satya Nadella and Microsoft CTO Kevin Scott. Former OpenAI leaders and board members may also be called.

Why it matters

This trial could pull private messages, internal notes, and other uncomfortable details into public view, like airing a company’s group chat in a courtroom. That matters because both Musk’s AI company xAI and OpenAI are linked to potential stock market listings, also called IPOs (when a company starts selling shares to the public). If damaging information comes out, it could affect how investors judge both companies.
