Democratic Wins Heighten Scrutiny of Data Center Expansion

Voters in the 2026 midterms delivered Democrats majorities in both chambers of Congress and a majority of governorships, shifting power toward officials who have pledged closer oversight of data center projects. The change immediately registered in markets, with chip and infrastructure stocks declining as investors weighed the prospect of new limits on construction.

The central tension lies between the scale of planned AI infrastructure and the political and regulatory response it now faces. Data centers require large tracts of land, substantial electricity and water, and often face local opposition over noise, emissions and tax incentives. Federal agencies control millions of acres that the prior administration had identified as potential sites, while states where new Democratic governors took office account for roughly half of the projected U.S. hyperscale pipeline, according to BMI, a Fitch Solutions unit.

Interior Secretary Doug Burgum disclosed holdings in AI-related companies valued between $18.1 million and $64.4 million on his 2026 financial forms, an analysis supplied by Save Our Parks showed. He also reported capital gains from those investments ranging from $2.1 million to $11 million in the year before joining the administration and between $2.5 million and $15.1 million in 2025. Burgum agreed to step down from his investment firm but retained the holdings. An Interior Department spokesperson stated that Burgum has met all ethics obligations and that suggestions of personal financial influence are unsupported. Ethics experts cited in the reporting noted that broad industry exposure can create appearance concerns even when no specific permit decision directly enriches an official.

Similar disclosures appear for other appointees. Bureau of Land Management Director Steve Pearce listed stakes in Nvidia, Meta, Microsoft, Apple and Alphabet, plus an interest in a real-estate firm involved in data-center land deals. He pledged to divest many of the AI holdings. Agriculture Undersecretary Michael Boren reported between $1.5 million and $6.1 million in xAI and up to $500,000 in a firm advancing a Utah project that would include more than 450 small nuclear reactors. EPA Administrator Lee Zeldin disclosed buying and selling up to $15,000 in Datavault AI shares in May 2025.

On the ground, more than 40 local ballot measures restricting data centers or removing tax breaks passed in the midterms; only one small North Dakota measure succeeded. In New Jersey’s 2nd congressional district, Democrat Zack Mullock defeated Republican incumbent Jeff Van Drew by three points after highlighting a permitted data-center project that had drawn hundreds of residents to planning meetings and triggered a $1.1 million state fine for unpermitted generators. Mullock told reporters that data centers were not the dominant campaign issue but formed part of broader voter concerns about affordability, corruption and regulatory oversight.

Industry participants responded by adjusting strategies. Equinix Asia-Pacific president Cyrus Adaggra told CNBC that the company’s typical 30-to-60-megawatt facilities fall below the 100-megawatt threshold appearing in many proposed restrictions, allowing continued investment where customer demand exists. Annualized gross bookings exceeded $500 million in the third quarter, up 35 percent from a year earlier. Capital spending has risen from roughly $2 billion to $7 billion in recent years.

Democratic leaders have signaled further action. Senate Majority Leader Chuck Schumer called for real steps on data centers, and groups of senators have written to Interior and EPA officials demanding transparency on public-land siting and withdrawal of a proposed rule that would reduce public comment periods for certain air permits. The unresolved question is whether these political signals translate into durable policy changes that slow construction or merely raise costs and shift projects to smaller footprints or overseas markets.
