Ahead of the midterm elections, Elon Musk has become the single largest campaign donor in any election cycle, giving about $450 million to Republicans. It is just a fraction of a percent of his near-trillion-dollar net worth.

Musk’s control over SpaceX, Starlink, X, Tesla and Neuralink, on top of his riches, has given him power over wealth, attention and critical infrastructure that few human beings have ever amassed before. What does he want to do with all this power? What is he trying to buy with his campaign spending? What is the world he wants to build?

Quinn Slobodian is a professor of international history at Boston University. He’s the author of “Globalists,” “Hayek’s Bastards” and, most recently, “Muskism: A Guide for the Perplexed,” which he co-wrote with Ben Tarnoff.
