Elon Musk and Tesla won a class action lawsuit alleging that Musk's comments manipulated Dogecoin's market, harming investors. U.S. District Judge Alvin Hellerstein dismissed the lawsuit with prejudice, meaning it is permanently dismissed. The lawsuit, filed in June 2022, claimed Musk and his firms, Tesla and SpaceX, defrauded investors through tweets and statements about Dogecoin. However, the judge ruled these statements as 'aspirational and puffery,' not factual, and stated that no reasonable investor could rely on them. Dogecoin's market value slightly declined following the decision.
