Elon Musk's unprecedented financial gamble on the 2026 midterm elections has backfired, resulting in significant losses for his favored Republican candidates and sending shockwaves through the markets. According to a CNBC analysis of campaign finance records, Musk spent at least $474 million across the midterms, with nearly half of that sum—$224 million—directed specifically toward Texas races. Despite this massive influx of capital, his supported candidates, including Senate nominee Ken Paxton and Governor Greg Abbott, were defeated in a sweeping Democratic wave.
The electoral defeats immediately rattled financial markets overnight, causing shares of SpaceX and Tesla to decline. Both companies have historically thrived under the business-friendly policies of the previous Texas administration. The broader technology sector also faced pressure as Democrats secured control of Congress, signaling a potential shift in regulatory oversight for the artificial intelligence industry.
Voters across the United States appeared to reject the growing influence of billionaires and major technology firms. This sentiment was echoed by Democratic Senator-elect James Talarico, who stated during his victory speech that big money must be removed from politics to prevent the top 1% from buying elections. J.C. Lintzenich, a senior fellow at the German Marshall Fund, characterized the results as a clear rejection of Musk's political alignment within the Trump orbit.
The political landscape in Texas poses specific challenges for Musk's operations, which include Tesla's largest U.S. vehicle factory near Austin and SpaceX's Starbase complex in South Texas. These facilities rely heavily on state decisions regarding electricity, water, environmental permits, and tax incentives. Democratic Governor-elect Gina Hinojosa, who campaigned against corporate subsidies and Musk himself, is expected to wield significant influence over these areas. Hinojosa has called for a moratorium on new data centers, an end to industry tax breaks, and requirements for developers to cover full electricity costs.
While Republicans retain control of the Texas Legislature, limiting Hinojosa's ability to overhaul state policy immediately, her administration could complicate Musk's expansion plans through stricter permitting processes and reduced business incentives. Nationally, Musk's America PAC spent nearly $87 million across 44 federal races, yet the candidates it backed lost 29 contests while winning only three. More than 93% of this spending went toward races that Republicans ultimately lost.
The outcome leaves Musk with fewer allies in a Democratic-controlled Congress, which may investigate his federal contracts and his past leadership role in Trump's Department of Government Efficiency. Although President Trump retains veto power and control over executive agencies, limiting Democrats' ability to reverse policies benefiting Musk's defense-tech businesses, congressional scrutiny could slow the growth of SpaceX's government contracts.
This election marks another instance where Musk's political spending failed to yield desired results, following similar outcomes in 2024 and a $20 million effort in Wisconsin last year. Longtime Tesla investor Ron Baron had previously warned that such activism risked alienating half the population. Other tech figures also faced setbacks; OpenAI President Greg Brockman and his wife contributed $25 million to shape AI regulation, while Andreessen Horowitz donated another $50 million.
The backlash extended beyond federal races to local issues regarding data centers. In Ohio, Democrat Sherrod Brown defeated Republican Sen. Jon Husted after attacking his support for data center expansion. Similarly, in South Carolina, Democrat Annie Andrews defeated Republican Sen. Darline Graham despite a late advertising push by the data center industry super PAC Building the Future. Nationwide, campaigns and outside groups spent $173 million on ads about data centers during the 2026 general election, with Democratic advertisers accounting for $140 million of that total. Voters also considered 41 local measures regarding data centers, approving bans or restrictions in at least 10 communities.
The financial implications of these political shifts are substantial. JPMorgan Asset Management estimates the AI infrastructure buildout could cost roughly $5 trillion through 2030, with about $2 trillion financed through investment-grade debt markets. Since projects cannot generate anticipated returns until fully operational, permitting delays and higher utility or borrowing costs could significantly raise expenses and jeopardize expected returns.
