U.S. stocks fall as data-center election backlash raises risks for AI investment

The assumption that AI infrastructure could keep growing with few political obstacles faced a fresh challenge on November 5, 2026. All three major U.S. stock indexes fell Thursday as investors questioned the AI boom’s staying power, two days after voters backed candidates and ballot measures seeking to curb the data centers supporting it.

Economic analyst Mark Hamrick told Hearst Television that investors had largely expected little to impede data-center construction and AI expansion. The economic stakes extend beyond individual projects: J.P. Morgan economists estimate AI-related investment accounted for nearly a quarter of U.S. economic growth over the past year.

Ballots put construction permission in question

The Washington Post reported that voters in at least 38 jurisdictions passed bans or restrictions on data centers on November 3. A broader, yearlong tally from Ballotpedia, cited by Hearst, found support for greater restrictions in 46 of 47 data-center ballot measures decided in 2026.

In Ohio, Georgia and Texas—three states with significant data-center development—voters elected governors who campaigned to temporarily halt new construction. Those victories concern campaign commitments, not newly enacted statewide bans.

Tax revenue meets the household power bill

The White House argues data centers create jobs and tax revenue. It cited more than $2.6 billion in Virginia state and local tax receipts, and $875 million in Loudoun County taxes in 2024.

Critics question environmental effects, permanent-job numbers and rising electricity costs. Hamrick said data centers had contributed to higher electricity costs. The administration says facilities should cover their own electricity costs rather than pass them to families.

The White House says hundreds of organizations have joined its voluntary Ratepayer Protection Pledge. Those commitments do not guarantee that electricity bills will remain unchanged.

Federal land offers a different siting strategy

Burgum told Hearst the administration is exploring more construction on federal land, framing data centers as a national-security need. He pointed to remote locations such as North Dakota and Alaska, where colder weather and relatively inexpensive electricity could lower operating costs. This is exploratory, not an announced construction program.

Democratic lawmakers have introduced proposals ranging from a nationwide construction moratorium to requirements that technology companies cover more electricity costs. They could receive renewed consideration under incoming Democratic majorities. But becoming law would require Trump’s signature or enough congressional votes to override a veto.
