Elon Musk plans to file a "thermonuclear lawsuit" against Media Matters and others over allegations of antisemitic content next to ads on his social media platform.

Media Matters identified ads by IBM, Apple, Oracle, and Comcast's Xfinity near antisemitic content, prompting major companies like Warner Brothers and Disney to pause their advertising.

Musk announced the lawsuit on X, formerly Twitter, stating it would be filed as soon as the court opens on Monday.

Musk endorsed a post falsely claiming Jewish people fueled hatred against whites, supporting the "great replacement" conspiracy theory.

In a statement, Musk accused Media Matters of misrepresenting X's experience, emphasizing X's commitment to free speech.

Despite the controversy, Musk didn't address the criticism of his tweet but previously denied being antisemitic.

Apple, previously a major X advertiser spending up to $100m annually, withdrew its ads, contributing to a decline in X advertisers and user numbers.

Musk introduced a paid premium system, claiming it targeted bots on the site.

The White House condemned Musk's tweet as an "abhorrent promotion of antisemitic and racist hate" conflicting with American core values.

White House spokesperson Andrew Bates referenced the October 7 attacks by Hamas against Israel, deeming it unacceptable to repeat lies after the deadliest day for Jewish people since the Holocaust.
