Musk's largess, which was reported earlier by the New York Times, makes the world's richest person likely the single-biggest political donor in this year's races, according to campaign finance records.

There is a lot at stake ​for Musk with Democrats in the US House of Representatives calling for investigations into his government contracts as CEO ​of aerospace company SpaceX (SPCX.O), opens new tab as well as his work running the Department of Government Efficiency, opens new tab ⁠under President Donald Trump.

Here is a breakdown of his political spending, which was confirmed by a spokesman for ​his super PAC America PAC.

Musk has spent $366 million so far this election cycle, which began January 1, 2025.

At ​least $276 million so far has gone to Republican groups and his own super PAC since July. Of the $276 million in third-quarter donations:

$158 million went to the Senate Leadership Fund, the super PAC set up to help elect Republicans to the Senate ​that is aligned with Senate Majority Leader John Thune, a Republican from South Dakota.

$20 million went to ​the Congressional Leadership Fund, the super PAC set up for House Republicans that is aligned with House Speaker Mike Johnson, ‌a ⁠Louisiana Republican.

$76 million went to Musk's America PAC.

$10 million went to the Lone Star Liberty PAC, which is supporting Republican state Attorney General Ken Paxton's run for the US Senate in Texas, where recent polls have him in a dead heat against Democrat James Talarico.

$10 million went to the Republican Governors Association.

$2 million ​went to the Republican Attorneys ​General Association.

America PAC ⁠is helping Republican candidates in seven battleground states and nearly three dozen House races.

The new giving will be publicly disclosed when many super PACs are required to ​disclose their third-quarter spending on Thursday.

Musk has also donated more money through groups ​that do not ⁠disclose their donors, according to the New York Times report.

Roughly $90 million spent this cycle paid for work done in the prior election or supported other issues, including 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, according to an America PAC spokesman.

Musk spent roughly $290 million during the last election cycle in which Trump won the presidential ​election race against former Vice President Kamala Harris.
