The tech mogul’s midterm donations backing Republicans have made him the largest single-cycle political donor in modern US history

Elon Musk has poured so much money into US politics this midterms election cycle that his donations could fund half a dozen SpaceX rocket launches or buy thousands of Tesla Cybertrucks. At the Tesla Diner in Los Angeles, Musk could order more than 31.9m cheeseburgers with the money he has spent on the midterms.

Musk, the world’s richest person, has funnelled at least $445.77m into Republican-aligned political action committees (Pacs) and groups since last year, according to US Federal Election Commission data as of 29 October. The contributions have made him the Republicans’ most prominent financial backer and the largest single-cycle political donor in modern US history.
