US Midterms Hand Data-Center Opponents Big Wins, Clouding AI Regulation Outlook

What happened

A Reuters analysis on Nov 4 called data center opponents among the biggest winners of the Democrats' landslide midterm wins, saying the results point to a shifting public mood on AI and that investors expect tougher regulation to follow. Democrats took control of the House and Senate in the Nov 3 midterms for the first time since 2023, according to reports; chip and AI-related firms including TSMC, Samsung, SK Hynix and Kioxia fell in Asian trading on Nov 4.

The sharpest change came in Texas. Democrat Gina Hinojosa ousted incumbent Governor Greg Abbott, ending three decades of Republican control of the office, while fellow Democrat James Talarico became senator-elect. Hinojosa campaigned on pausing new data center construction until the state legislature puts real protections in place, and on ending tax exemptions for the sector. GLJ Research estimates Texas accounts for about a quarter of US data center capacity due to come online by 2030.

Georgia also flipped. Democrat Keisha Lance Bottoms won the gubernatorial contest, ending more than two decades of Republican control, and she wants a temporary freeze at the state level on building new data centers. Commercial real estate firm CBRE says Atlanta is the most active data center construction market in the country. Opponents say data centers drive up utility bills, consume large amounts of water, pollute the night sky with light, and do not create enough jobs or taxes to justify the incentives states pay.
