Elon Musk is reported to have spent about $276 million on Republican political groups ahead of the 2026 US midterm elections, making him the biggest known donor in the cycle. Multiple outlets cite recent federal filings and reporting ahead of deadlines, saying the money flows through Musk-affiliated super PACs and related organizations in the final stretch of campaigning.
Reports agree that a large share—about $158 million—goes to the Senate Leadership Fund, a super PAC supporting Republican Senate candidates. Other disclosed donations include roughly $76 million to America PAC and about $10 million to Lone Star Liberty PAC, which backs a Republican Senate nominee in Texas. CNBC and others also link the increased spending to Musk’s improving relationship with Donald Trump and note Musk’s business ties to the federal government.
Some outlets reference a higher total figure, including claims of about $366 million, though the largest consistently described breakdown in the reporting centers on the $276 million figure. Democrats, where quoted, criticize the spending as an attempt to offset voter dissatisfaction, while Republicans describe it as supporting their electoral infrastructure.
