Over the course of one weekend in July, the presidential election was turned on its head. This is when news organizations announced that Elon Musk was backing Donald Trump—and gave a real endorsement, something he said he’d never do. What does it mean that the world’s richest man has been united with not just any presidential candidate, but Trump? In this three-part series from Elon, Inc., we will explore how Musk’s politics have (and haven’t) changed over time; what the mercurial CEO of a huge social network can do to tilt the information war in presidential politics; how money, dark and light, provides the infrastructure for the 2024 presidential race; and finally, what is at stake for Musk himself in this unprecedented dive headfirst into the political sphere.
