During a recent online clash with Sam Altman, the CEO of OpenAI, Elon Musk experienced an unexpected twist when his own AI chatbot, Grok, publicly sided with Altman. The confrontation began after Musk accused Apple of unfairly promoting OpenAI’s ChatGPT in the App Store.

In March 2026, a jury will hear OpenAI's claims of a "years-long harassment campaign" by Musk via social media, press, and legal moves.

A federal judge on Tuesday denied Elon Musk's bid to dismiss OpenAI's claims of a "years-long harassment campaign" by the Tesla CEO against the company he co-founded in 2015 and later abandoned before ChatGPT became a global phenomenon.
