Talarico’s victory marked a key turning point in the midterms, helping solidify the Democrats’ control of the US Congress in a wave of wins across the US.
Musk has increasingly made Texas the hub of his companies, from Tesla’s Austin headquarters to SpaceX’s Starbase launch site.
As well as backing Paxton through outside groups, the X owner took to his own platform to spread conspiracy theories about the Democrat, posting: “There is something deeply wrong with Talarico” after he briefly disappeared from the campaign trail in October.
“There is something deeply wrong with a political system that allows one trillionaire to buy his own personal US Senator,” Talarico posted in response.
On top of contributing to one of the most expensive Senate races ever, the SpaceX owner also became the top individual donor in this year’s midterms overall, contributing an estimated $446m in backing Republican candidates.
Musk’s money went through Super Pacs, groups which can raise unlimited sums but can’t give directly to candidates or coordinate with their campaigns.
Individuals, parties and traditional groups face legal limits on direct donations.
Super Pacs get around this by spending independently, such as on ads backing a candidate.
Musk became one of the Republican Party’s biggest donors in 2024, pouring hundreds of millions of dollars into Donald Trump’s winning presidential campaign.
A similarly eye-watering amount was not enough to do the same for Paxton this time around.
