The court hearing concerns posts on Twitter, now known as X, by Musk, who claimed that the platform had an inappropriate number of fake accounts and that the billionaire therefore wanted to back out of the deal; the acquisition was later completed in 2022.
According to the jury, the Tesla billionaire made these posts in order to be able to buy Twitter for a cheaper price than the $44 billion he initially offered.
The jury's decision means Musk will now have to pay damages to investors. The amount of money involved - potentially tens of billions of kronor - will be announced at a later date.
