A federal judge denied Elon Musk‘s effort to upend a March jury verdict that he defrauded investors during his 2022 Twitter acquisition, though the judge handed Musk a minor concession in the dispute over his social media posts.

U.S. District Judge Charles Breyer ruled Monday that Musk’s May 13, 2022, tweet complaining about the number of bot accounts on Twitter, now called X, did deflate the social media platform’s stock price just as he was in negotiations to purchase it. Yet Breyer struck down a separate claim that a tweet from Musk four days later did the same.
