Musk also directed $76 million to his own America PAC, $10 million to the Lone Star Liberty PAC supporting Texas Attorney General Ken Paxton, $10 million to the Republican Governors Association, and $2 million to the Republican Attorneys General Association. An America PAC spokesman confirmed these figures.

Other Expenses

Roughly $90 million spent this cycle paid for work done in the prior election or supported other issues. This included an unsuccessful candidate for the Wisconsin Supreme Court and a controversial program paying $1 million to registered voters who signed a petition supporting free speech and gun rights. The New York Times reported that Musk also donated more money through groups that do not disclose their donors. Public disclosures for third-quarter spending are set for Thursday, October 15, 2026.

Context

Political donations by wealthy individuals and super PACs play a major role in modern U.S. elections by funding advertising, ground operations, and voter outreach. Large contributions often draw intense public scrutiny regarding the political influence of billionaires on legislative outcomes and government contracts.
