For Musk, who has called Bezos’ company “Sue Origin,” this fight is personal and years in the making. In an early Thursday morning post on his platform X, he gleefully accused Bezos of telling others to sell their SpaceX and Tesla stock because Trump would lose the election. Tesla stock prices have soared since news of Trump’s victory.

Elon Musk's claim about Bezos' election predictions on Trump was "100% not true," Bezos responded on X. “Nope. 100% not true," Bezos responded to Musk's assertion.

Elon Musk reignited a public dispute with fellow billionaire and space-industry rival Jeff Bezos, saying the Amazon.com founder had said President-elect Donald Trump would lose the election and that people should sell stock tied to Musk.
