Elon Musk has contributed more than $442 million to political efforts during the 2026 election cycle, including a fresh $76 million infusion into his America PAC during the first half of October, as Republicans work to retain control of Congress.

The latest contributions push Musk’s spending beyond the approximately $290 million he spent during the 2024 election cycle. The billionaire, who leads Tesla and SpaceX, has become the largest individual political donor of the current cycle by a substantial margin.

America PAC, which Musk controls, has directed millions of dollars toward competitive House and Senate races through online advertising, direct mail and text messages. The group has emerged as a major source of outside spending ahead of the Nov. 3 midterm elections.

Texas has received particularly significant financial backing. Earlier in the cycle, Musk contributed $158 million to the National Republican Senatorial Committee, which subsequently directed the funds to a super PAC supporting Texas Attorney General Ken Paxton in his Senate race against Democratic nominee James Talarico.

Talarico has criticized Musk's financial involvement in the contest. After Musk attacked him on X, the social media platform Musk owns, Talarico argued that the political system allows an extremely wealthy individual to exert excessive influence over Senate elections.

Musk's political spending extends beyond Texas. He has also supported outside groups backing House Republicans and President Donald Trump, including MAGA Inc., as well as an effort to overturn Alaska's ranked-choice voting system and several individual Republican candidates.

Despite the scale of his financial contributions, Musk has maintained a lower public profile during this election cycle than in previous campaigns. He has not appeared alongside Republican candidates this fall, following political concerns that emerged after the April 2025 Wisconsin Supreme Court race.

Musk was the largest spender in that closely watched contest, which Republicans lost, and Democrats made his involvement a central campaign issue. Republicans subsequently expressed private concerns that his presence could become a liability for their candidates, according to Politico.

His financial support, however, remains a major component of Republican outside spending as the Nov. 3 elections approach.
