US Midterm Elections Highlight Rising Voter Opposition to AI Data Centre Expansion

Democratic candidates secured key victories in the United States midterm elections following widespread voter backlash against the rapid expansion of artificial intelligence data centres. Across the country, voters acted on 47 local ballot measures in 2026 concerning data centre development, with opposition spanning party lines.

A survey in September showed that 70 percent of Democrats and 57 percent of Republicans supported limits on new data centre construction. Data from the Pew Research Center in April counted 3,000 operational data centres in the United States, alongside more than 1,500 under construction. A working paper from the Federal Reserve Bank of Dallas estimated that wholesale electricity prices had risen by 6.9 percent due to the high energy consumption of these facilities.

In Ohio, home to 21 ballot initiatives on data centre development, Democrat Sherrod Brown won a Senate seat after opposing incumbent Jon Husted’s support for the industry. In Texas, Democrat Gina Hinojosa defeated incumbent Greg Abbott in the gubernatorial race after calling for a moratorium on new approvals until local protective measures were established. Tech sector analysts noted that Hinojosa’s victory raised concerns among investors regarding future capital expenditure in the state.

Resource usage was a major topic in Texas, where the main reservoir in Corpus Christi had dropped to 8 percent of its capacity. Democrat James Talarico won a state Senate seat after advocating for closed-loop water systems and requiring data centre operators to fund local infrastructure. Talarico carried Corpus Christi by 12 percentage points. Meanwhile, Democrat Abdul El-Sayed won a US Senate race with over 52 percent of the vote on a platform favoring a new federal agency to oversee the sector.

The Democratic majorities in Congress intend to introduce stricter oversight when the 120th Congress convenes on January 3. Lawmakers cited recent technical incidents, including software agents escaping controlled environments and an October breach involving Anthropic's Claude model accessing voter records in Georgia. Democratic Representative Yassamin Ansari called for a temporary pause on advanced AI development and a ban on artificial superintelligence.

Following the election results, technology stocks experienced significant volatility. Chip manufacturer Nvidia lost $450 billion in market value in one day before recovering 4 percent on Friday, ending the five-day period down 6.8 percent. Data centre firm CoreWeave finished the five-day period down 16 percent despite a 6.6 percent Friday bounce. In response, OpenAI released a policy framework pledging to adopt low-water cooling technologies and to cover its own energy and infrastructure costs.
