Elon Musk Found Not Liable in Trial Over Tweets Proposing to Take Tesla Private

SAN FRANCISCO—A jury rejected investor claims that Elon Musk violated federal securities law when he tweeted in 2018 about potentially taking Tesla Inc. private, handing a major win to the billionaire chief executive.

The nine-person jury said the investors who brought the class-action case failed to prove that Mr. Musk hurt them by tweeting about a possible deal.
