The long and short of it: The fight between the tech bros will continue apace. Nothing has been decided in the case, but, as Reuters reported, U.S. District Judge Yvonne Gonzalez Rogers ruled that Musk has to face harassment claims from OpenAI, which accuses the xAI chief of engaging in a years-long campaign to harm the AI company.

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.

He called OpenAI boss Sam Altman a "liar" - after Altman claimed Musk used his platform to "benefit himself and his own companies". The row is the latest flashpoint in what is an ongoing feud between the billionaires who co-founded OpenAI - but now fiercely compete after Musk left the firm.
