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.

Elon Musk must face claims by OpenAI that his attacks on the startup in court and in the media amount to a “years-long harassment campaign,” a federal judge ruled.

The billionaire said in posts on X that the consumer tech giant was violating antitrust laws by giving preferential treatment to OpenAI on the App Store.
