Musk's Record Midterm Spending Ends in Republican Defeats and Falling Stocks

The money was extraordinary before the votes were counted. On October 31, MarketWatch reported that 10 megadonors had spent a combined $1 billion on the midterms. By November 2, the BBC reported that the top 40 donors had given $2.4 billion through October 14, citing the Brennan Center for Justice.

Elon Musk stood out even in that company. The Next Web, citing a published analysis, put his contributions to political groups at $474 million. It reported that no donor had given more in a single election cycle, apart from wealthy candidates financing their own campaigns.

The coverage uses different totals for his spending. FlowingData reported $446 million, while The Hill later described more than $442 million spent boosting Republicans. The supplied reports do not fully reconcile those figures, but all place his contributions in the hundreds of millions.

On November 2, The Globe and Mail reported that the elections were on track to be the most expensive in at least two decades, based on its analysis of Federal Election Commission data. NYT Politics described more than $11 billion in advertising spending alone.

The November 3 results delivered a stark reversal for Musk's political investment. Democrats captured both the Senate and House of Representatives, The Hindu reported.

Texas supplied a particularly expensive defeat. The Independent reported that Musk donated more than $200 million to Republican Ken Paxton's campaign. The Verge reported that Democratic Texas senator-elect James Talarico won the race, which it described as the most expensive Senate election to date, with more than $573 million spent on advertising.

Early on November 4, Musk responded with jokes about space lasers after the Republican losses, according to Axios. News18 also reported jokes about data centres following the defeat.

The consequences extended beyond campaign spending. On November 4, MarketWatch reported that Tesla and SpaceX shares slid as investors worried about less favorable policies under new Democratic officials.

Democrats have won control of Congress, and Musk's record spending did not prevent major Republican defeats. That establishes a clear limit to what his money achieved this cycle, though the supplied coverage does not provide a complete accounting of every candidate he backed.

The political setback now carries business risks. The New York Times reported that some Democrats have signaled plans to investigate Musk when they take control of Congress. NPR identified his influence, leadership of DOGE and government contracts as likely subjects of scrutiny.

By November 5, The Daily Beast reported that Musk had deleted an election-day post urging support for Republicans. Business Insider had reported the disappearance of his "vote red" post the previous day.

The next concrete question is whether Democrats turn their stated interest in Musk into formal congressional investigations. The coverage identifies potential subjects, but does not establish a timetable or the scope of any proceedings.

For Tesla and SpaceX, watch for specific policy decisions rather than treating the initial share declines as proof of lasting damage. MarketWatch attributes the selloff to investor concerns about less favorable policies, while Reuters reports that Musk's business empire is bracing for the Democratic gains in Texas.
