Tech mogul Elon Musk poured $10 million into two major Republican super PACs at the end of last year, according to campaign finance disclosures submitted Saturday, as he once again takes a more active role in GOP politics.

The Tesla and SpaceX CEO, who had a public falling out with President Donald Trump last spring and said he was giving up on political spending, gave $5 million in December to each of the Congressional Leadership Fund and Senate Leadership Fund, two groups that aim to help the GOP keep control of Congress this year.

It was Musk’s second round of donations to both groups this cycle, having previously given in June, amid his feud with Trump. Those contributions came shortly before Musk floated starting his own political party, an initiative that never seemed to gain much headway.

But Musk and Trump have patched up their differences more recently, with the tech CEO joining Trump for dinner at Mar-a-Lago earlier this month. Musk has also been back to advocating for Republican politics on X, which he owns, pushing for senators to pass a plussed up version of the SAVE Act, a bill that would require states to collect proof of citizenship from people registering to vote.

Musk has thrown his support behind a version called the SAVE Act Plus, calling for ID requirements and a ban of mail voting for most Americans along with other changes to election administration.

Musk was the biggest individual donor to political committees during the 2024 election cycle, spending roughly $290 million, mostly through his own super PAC, America PAC, in support of Trump.

In the first few months of the Trump administration, he played an active role with the Department of Government Efficiency, but began fighting with Trump and Republicans around the president’s One Big Beautiful Bill Act. Musk also threw himself into a Wisconsin Supreme Court election in April where his preferred candidate lost by 10 points.

Musk’s funds accounted for just a fraction of total fundraising for both SLF and CLF. SLF raised nearly $77 million in the final six months of 2025 and had $100 million cash on hand, while CLF raised over $38 million over that period and had more than $54 million cash on hand.
