Elon Musk, facing the fact that an already financially-precarious X could be poised to lose another $75 million in ad revenue following his boosting of an antisemitic conspiracy theory, has a new message for advertisers pulling back from the platform: “Go fuck yourself.”

Musk repeated the sentiment multiple times during an appearance at The New York Times’ DealBook event. “Don’t advertise,” Musk said. “If somebody is going to try and blackmail me with advertising, blackmail me with money? Go fuck yourself. Is that clear? I hope it is.”

“Hey Bob,” Musk added, in an apparent reference to Disney CEO Bob Iger, who appeared at the same event earlier in the day and spoke about the company’s decision to pull ads following Musk’s tweet earlier this month. Iger said that Disney’s association with X was “not necessarily a positive one for us,” according to Variety.

While Musk again denied being antisemitic, he did express some regret for engaging with the tweet that’s resulted in another exodus of advertisers from X. “I should have not replied to that particular person… I essentially handed a loaded gun to those who hate me,” Musk said about the post, per Variety.

X didn’t immediately respond to a request for comment. X CEO Linda Yaccarino had a front-row seat to the remarks, according to The Hollywood Reporter, which reports the former ad exec sat “stone-faced” during Musk’s tirade.
