The market valuation of Elon Musk’s primary publicly traded companies, Tesla and SpaceX, dropped by approximately $159 billion on Wednesday, October 4, 2026, according to Le Figaro. This financial decline followed the midterm elections in the United States, which resulted in significant losses for the Republican Party and a shift in power within the federal government.
Investors reacted to the prospect of a more challenging political landscape for Musk’s industrial projects, as the Democratic Party secured control of both the U.S. Senate and the House of Representatives. In the immediate aftermath of the election, shares for Tesla and SpaceX fell by 3.78% and 3.46% respectively at the opening of trading on Wall Street. The downturn also affected the broader technology sector, including semiconductor manufacturers such as Intel and Nvidia.
Electoral Defeat in Texas
The election results were particularly consequential in Texas, where Musk has established a significant industrial base, including Tesla’s headquarters in Austin and the Starbase production and launch facility for SpaceX. Despite Musk investing roughly $446 million of his own funds to support Republican candidates, the party suffered a series of defeats in the state.
Guess my election-interfering space lasers didn’t work this time 🤷♂️

James Talarico, the Democratic challenger, defeated Ken Paxton in the race for a Texas Senate seat, marking the first time a Democrat has won that position in the state since 1988. Democrat Gina Hinojosa was elected governor, unseating the incumbent Republican, Greg Abbott.
Throughout her campaign, Hinojosa identified Musk’s business interests as a target, specifically opposing the allocation of public land to SpaceX and criticizing the financial incentives provided to his companies. She has also advocated for a moratorium on the construction of new data centers in Texas, citing concerns over the high consumption of water and electricity and the pressure these facilities place on the state’s electrical grid.
Data centers in space looking pretty appealing right now

Future Regulatory Challenges
Analysts suggest that a Democratic-controlled Congress may complicate Musk’s business operations. Potential scrutiny includes investigations into his role in the White House, specific decisions regarding Ukraine, and the strategic importance of SpaceX within the American state apparatus. SpaceX relies heavily on contracts with the National Aeronautics and Space Administration (NASA) and the U.S. military, which are funded by budgets approved by Congress. Any future efforts to integrate Tesla and SpaceX would require official authorization.
Musk’s Response
Following the election, Musk addressed the results on his social media platform, X.
Regarding the threat to his data center developments, Musk wrote on X that data centers in space looking pretty appealing right now. While SpaceX has previously explored the concept of orbital data centers, industry analysts from Deutsche Bank have noted that such technology is not expected to become competitive with terrestrial installations until the 2030s. For now, Musk faces the prospect of negotiating with a new Democratic administration in Texas.
Elon Musk was among the biggest losers of election night. He doled out around $446 million — the most a non-candidate has ever spent on an election — but his preferred candidates were swamped, losing almost everywhere.https://t.co/Ne6FNT7TyD

Elon Musk moving to Texas to get away from Dems, becoming the biggest partisan megadonor in history, then spending around a half-billion dollars to have his own state go blue immediately in the next election — with data centers the top gov issue — is pretty impressive
