X CEO Elon Musk lashed out during a New York Times event Wednesday when asked about recent advertiser boycotts over Musk’s reposting of antisemitic content.

Elon Musk: “If somebody is going to try to blackmail me with advertising, blackmail me with money, go fuck yourself. But — go fuck yourself. Is that clear?”

Over 100 brands have halted their ads on X, formerly Twitter, which stands to lose $75 million in ad sales by the end of the year.
