American billionaire Elon Musk pumped more than $445 million into campaign funding and federal political committees during the 2026 election, becoming the largest declared donor in modern American politics, and one of the most prominent funders in Republican Party history, at a time when attention is turning to decisive congressional races. According to political spending data as of mid-October, Musk's donations more than double the amounts provided by prominent Democratic donor George Soros, who spent about $177 million on political groups during the 2022 midterm elections, and was then the largest known single donor.
