Billionaire Elon Musk, owner of the X platform, has given more than $276 million to Republican causes ahead of the U.S. midterm elections, prompting debate over his political goals, his relationship with President Donald Trump, and his effort to keep his influence over the party after the Trump era.

According to U.S. media reports, roughly $158 million of the donations went to the Senate Leadership Fund, which aims to preserve the Republican Senate majority, while more than $76 million was directed to his own political action committee, America PAC. Musk gave about $288 million to Trump and other Republican campaigns in the 2024 presidential race. Much of the money flows to party organizations rather than individual candidates, and America PAC is focusing on voter registration and turnout.

Musk's influence also rests on control of X, which has become a key channel for politicians to reach voters and shape debate; critics argue the platform can serve particular political interests. Reports say Trump's advisers asked Musk to repeat his 2024 field operations, despite his pledge in June 2025 to cut political spending after a falling-out with Trump. A Politico report said Musk envisions 12 years of Republican rule, including two terms for Vice President JD Vance, and more than a third of his known spending has targeted races in Texas.
