Democrats’ victories in the 2026 US midterm elections have dealt a blow to President Donald Trump, technology billionaires, and corporate groups that spent hundreds of millions backing Republican candidates.
The results put Democrats in control of Congress and intensified scrutiny of AI, data center expansion, and wealthy donors’ influence. Rising prices, government corruption, and concerns about AI infrastructure shaped voters’ choices.
In Texas, James Talarico defeated Ken Paxton, becoming the first Democrat elected to the US Senate from the state in nearly four decades. Gina Hinojosa defeated three-term Governor Greg Abbott, becoming Texas’ first Democratic governor since Ann Richards left office in 1995.
Democrats flipped Senate seats in Iowa and North Carolina, while Sherrod Brown defeated Republican Senator Jon Husted in Ohio. Annie Andrews upset Darline Graham in South Carolina, and Roy Cooper won in North Carolina. Trump had endorsed several defeated candidates.
Elon Musk, the world’s richest man and the cycle’s largest individual political donor, spent record sums trying to help Republicans retain power, including more than USD 200 million to stop Talarico in Texas.
Voters raised concerns about government corruption and billionaires’ growing influence. Talarico accused Musk of trying to buy ‘his very own personal United States Senator.’
A CNBC analysis of Federal Election Commission records found that 14 of the 20 largest donor groups backed Republicans exclusively or almost exclusively. Crypto, AI and online gambling interests poured more than USD 377 million into races.

Opposition to data center expansion has become the central topic of debate. In a CNBC Voter Poll, 56% of voters said data centers were a crucial or major factor in their decision, and 69% agreed that benefits flow to the wealthy. Hinojosa campaigned for a pause on new projects until Texas adopts tougher rules.
Democrats are expected to use their congressional majority to increase scrutiny of technology companies. Representative Greg Casar said AI company CEOs should be called to testify under oath. Representative Robert Garcia put it simply, stating, ‘Lawyer up.’
The results point to a more difficult political environment for technology companies.
