US stock futures declined on Wednesday as midterm election results confirmed a Democratic sweep of both the House and Senate, delivering a significant political setback to President Donald Trump. Investors quickly shifted focus to the potential regulatory implications for the technology sector, particularly around artificial intelligence and data-center infrastructure.
Nasdaq-100 futures tumbled as much as 2% in overnight trading, while S&P 500 futures dropped around 1.2%. By Wednesday morning, losses had narrowed, with Nasdaq futures down 0.45% and S&P 500 futures lower by 0.35%. Dow futures were off 0.18%.
The US dollar weakened to a more than one-month low, and the 10-year Treasury yield fell toward 4.90% as investors sought safety in government bonds amid political and economic uncertainty.
Democrats Secure Major Victories
Democrats captured several key Senate races in traditionally Republican states, including Texas, Kansas, and South Carolina, securing control of the upper chamber. They also flipped at least eight House seats, giving them a majority in the lower chamber as well.
In Texas, Democrat James Talarico defeated Republican Attorney General Ken Paxton, marking the first Democratic Senate victory in the state since 1988. In Kansas, pastor Adam Hamilton ended a 94-year Republican hold on the seat by defeating incumbent Roger Marshall. Democrats also won in South Carolina, Ohio, and North Carolina, while Georgia Senator Jon Ossoff was reelected.
President Trump, who had campaigned heavily for Republican candidates, acknowledged the outcome. "Congratulations to the Democrats. They did a good job. They've been looking for this one for 11 years, and they finally got it," he told Fox News. He added, "But I don't view it as a hit on me. I think we've done … We've had the greatest two years in the history of the presidency."
AI Infrastructure Spending Under Scrutiny
Technology stocks bore the brunt of the initial selloff as investors weighed the likelihood of tighter oversight of artificial intelligence companies and data-center construction. A Democratic-controlled Congress could introduce stricter permitting requirements, additional regulation of major tech firms, and greater scrutiny of the energy and water consumption of large AI facilities.
These measures could delay infrastructure projects and slow the expansion of AI computing capacity, a critical concern for companies investing hundreds of billions of dollars in data centers, chips, and power infrastructure. "A Democratic sweep of Congress would put pressure on tech and potentially bring regulatory pressure on everything AI," said Jake Dollarhide, chief executive of Longbow Asset Management, as cited by Reuters.
Asian Markets Feel the Impact
The concerns rippled across Asian markets, where technology and semiconductor stocks faced selling pressure. Japan's Nikkei 225 fell 1.6%, while South Korea's Kospi reversed an early decline to gain 0.59%. Taiwan's Taiex lost 0.8%. Shares of Samsung Electronics dropped, but SK Hynix remained steady as investors assessed the potential impact of tighter US regulation on AI infrastructure demand and semiconductor supply chains.
Market participants will now watch for further policy signals from the new Congress, particularly regarding tech regulation and fiscal spending, which could influence market direction in the coming weeks.
