Tuesday’s midterms supplied the political shock. Voters in Ohio approved 21 measures opposing data centers, including a Piqua ban that could threaten Meta’s planned $1 billion project; incoming leaders in Texas and Georgia also backed moratoriums or tougher rules. In California, Alhambra joined Monterey Park in approving a ban. The message was not anti-technology in the abstract—it was a demand for more local control over the power-hungry physical machinery behind AI.¹

The market initially looked past it. Shares rallied Wednesday after Democrats retook Congress, but executives were already acknowledging a harder landscape. Meta President Dina Powell McCormick said building American data centers was “going to be harder,” and that hyperscalers were weighing construction abroad to hedge enormous investments.² AMD chief Lisa Su offered the industry’s counterargument: AI companies must ensure “everybody wins from AI” and make their value clear to host communities.¹

By Thursday, that political risk became a full-blown rout. The S&P 500 fell about 4%, while the Nasdaq dropped roughly 5.5%, largely erasing the prior day’s gains.³ Chipmakers and debt-heavy data-center operators took the harshest punishment as investors repriced the pace—and financing—of the build-out.

Yorkville Ives analysts projected that at least 10% of the 800 to 1,000 planned AI-focused U.S. data centers could be removed from the roadmap, with as many as 20% facing prolonged regulatory delays. Yet Aprio Wealth Management’s Simeon Wallis cautioned that markets can “over-react in the short term” when guessing at future winners and losers.²

The political reaction was quickly absorbed into the market narrative. David Sacks amplified a podcast post describing a “$4T Wipeout,” data-center fears and potential AI restrictions—evidence of how rapidly a local backlash had become a national investor alarm.David Sacks (DavidSacks)⁴
