Elon Musk's $474 Million Election Bet Falls Short as Democrats Sweep Republicans

Despite contributing nearly half a billion dollars to Republican political campaigns, Elon Musk's efforts to help the party retain control of Congress fell short in the November 3 midterm elections.

The world's richest person donated at least $474 million to Republican candidates and political groups ahead of the 2026 elections, nearly twice the amount he contributed before the 2024 presidential election.

However, several high-profile candidates he supported suffered major defeats, Sasha Rogelberg reported for Fortune.

Musk's donations included approximately $200 million directed toward political efforts in Texas, where Democrat James Talarico defeated Republican Senate nominee Ken Paxton and Democrat Gina Hinojosa defeated incumbent Gov. Greg Abbott.

Musk's other contributions included $30 million to the Congressional Leadership Fund, the principal super PAC supporting House Republicans, and approximately $44 million to other Republican groups and candidates seeking federal office.

He was among the largest Republican donors during the election cycle, alongside venture capitalists Marc Andreessen and Ben Horowitz, who contributed a combined $116.4 million, and OpenAI co-founder Greg Brockman and his wife, Anna, who contributed approximately $50 million.

The results highlighted the limits of campaign spending in determining election outcomes.

Despite Musk's substantial financial backing, voters in several key races chose Democratic candidates.

“I think this might just be the biggest defeat for big money in politics in American history,” Logan Phillips, founder of the election forecasting site Race to the White House, told Fortune.

However, political analysts cautioned that Musk's spending may still have long-term influence by helping shape Republican priorities and policy debates ahead of the 2028 elections.
