AI Data Centers and the 2026 Midterms: What the Election Results Mean for AI

Updated November 4, 2026. This is a live story: several races are still being counted, and every result here is preliminary until certified.

AI data centers were one of the surprise issues of the 2026 midterms. In Tuesday's vote, local measures to ban or restrict data centers passed almost everywhere they appeared. Candidates who promised to slow the buildout won major races, and by Wednesday morning AI infrastructure stocks were falling.

This explainer covers what happened, the numbers so far, and what it could mean for how AI gets built in the US.

AI data centers in the midterms: the short version

• 41 data center ballot measures in 10 states were on the November 3 ballot, according to Ballotpedia. Ohio had 21 of them.
• Ohio voters rejected the AI buildout almost everywhere. Fortune counts at least 14 Ohio municipalities that passed bans or other restrictions. Euronews puts it at 15.
• 56% of voters said AI and data centers were a "crucial or major factor" in their congressional vote, according to the NBC News exit poll. 76% said they oppose a data center in their own community.
• Texas elected Gina Hinojosa governor (a projected result). She has called for an immediate, temporary moratorium on new data centers.
• AI stocks slid. CNBC reported CoreWeave and SpaceX down 7%, Iren down 6% and Oracle down 4.3%, while Alphabet, Meta and Microsoft were mostly higher.
• Pro-AI money mostly stayed quiet. Time reports that the pro-AI super PAC Leading the Future, launched with more than $100 million, largely held back as the election got closer.

How data centers became a midterm election issue

Data centers are the giant warehouses of servers that train and run AI models like ChatGPT, Claude and Gemini. The newest "hyperscale" AI campuses can draw hundreds of megawatts of power. That's as much as a small city. They also use a lot of water for cooling and take up large plots of land.

Many communities have pushed back over the past year. Their worries are rising electricity bills, noise, water use, tax breaks for very rich companies, and secret deals made before residents hear about them.

Step 1: Local fights turned into votes

The first votes came early in 2026. In April, Port Washington, Wisconsin passed what was reported as the nation's first referendum restricting AI data centers, with about 66% support. In June, Monterey Park, California approved a permanent ban (Measure NDC) with roughly 86% of the vote, according to Ballotpedia.

By Election Day, Ballotpedia counted 41 data center measures on ballots in 10 states.

Step 2: Candidates picked sides

Data centers then turned up in big statewide races. Time reports that Democrats spent more than $100 million on broadcast ads that cast their Republican opponents as too close to Big Tech and data centers. In Ohio, Sherrod Brown's ads called his opponent Jon Husted "the face of data centers in Ohio." In Wisconsin, the Republican candidate for governor gave his opponent the nickname "Data Center David Crowley."

Republicans moved on the issue too. In September, Texas Gov. Greg Abbott paused new data center permits until the state's grid operator finished an audit. That was a reversal for a governor who had pitched Texas as an AI "epicentre," Euronews notes.

Step 3: The industry's money went quiet

Leading the Future, a super PAC created in August 2025 to back pro-AI candidates, launched with more than $100 million. Time reports that its donations drew backlash, that some promised donors backed away, and that the PAC mostly held back late in the race. A related group, Build American AI, spent at least $2.54 million on Ohio TV ads that promoted $40 billion in investment and more than 95,000 jobs, according to Fortune. Those ads didn't endorse any candidates.

The data center ballot measures: what passed

Ballotpedia sorted the 41 measures into two groups. 28 would limit development: 17 bans (12 of them only for facilities above a size limit), 3 six-month moratoriums, voter-approval requirements, a financial-guarantee rule and more. The other 13 would make development easier, mostly through rezoning and non-binding approval votes.

Ohio: 21 measures, almost all against data centers

Ohio is the main battleground. It has more than 200 operating data centers, the fifth most of any state, and companies plan to invest up to $40 billion in AI infrastructure there by 2030, according to Fortune. More than 125 local moratoriums were already in place before the vote.

Fortune's early tally of Tuesday's results:

• Sunbury passed a charter amendment banning data centers of 25 megawatts or more, with 100% of the unofficial vote counted. The measure targeted a possible hyperscale Amazon project.
• Trenton passed its ban by about 80% to 20%. The ban was aimed at an 18-building AWS campus, but it likely won't affect a four-building AWS campus that's already under construction.
• Pataskala approved a charter ban on large data centers.
• Perry voters, at more than 87%, approved requiring developers who get tax breaks to give the village financial guarantees.
• Wilmington voters rejected rezoning in four referendums, each by about 80%.
• All five central Ohio communities with measures on the ballot voted against data centers.

Some Ohio results, such as Oregon's, were still unavailable Wednesday morning.

Elsewhere

Time reports that bans or moratoriums also passed in Edgewater, Florida and Bloomington, Illinois. The mayors of Piqua, Ohio and Yukon, Oklahoma were recalled over their past support for data center projects. Stratechery, citing Stateline, says the one early exception was in North Dakota, where a measure opposing data centers did not win.

The races where data centers mattered

Here's what outlets reported as of Wednesday morning. Several races were still being counted.

• Ohio Senate: Sherrod Brown beat Jon Husted by about five points, according to Time. Brown wants to end data center tax breaks and make developers pay for the utility upgrades their projects need. Husted supported the tax breaks.
• Texas governor: Gina Hinojosa's projected win would make her the state's first Democratic governor since 1990, Stratechery notes. She has called for an immediate, temporary moratorium on new data centers until the legislature puts protections in place.
• Kansas governor: Cindy Holscher led on Wednesday morning, but the race had not been called. She ran on pausing data centers until the state sets guardrails.
• Arizona: Amish Shah, who promised to "stop data centers from being built," was leading but had not been declared the winner in Time's report.
• Wisconsin governor: David Crowley called for tighter data center rules in October and won, Time reports.

Politico's analysis argues that Democrats who made Big Tech a foil "couldn't stop winning." That was the party pattern this cycle, but the opposition to data centers itself crosses party lines. University of Michigan researcher Ben Green told Fortune that both parties object to companies working in secret without giving communities a say.

The numbers: how voters feel about AI

The NBC News exit poll is the clearest single snapshot:

• 56% called AI and data centers a crucial (23%) or major (33%) factor in their vote. AI still ranked last of the five issues NBC asked about, so the economy and other issues mattered more.
• 76% oppose building a data center in their own community.
• 57% think AI will do more to hurt society than help it.
• Voters were split almost evenly over which party would handle AI better.

Other polling shows the same mood. Gallup found about 70% of Americans opposed data centers in their area in May. In Ohio, an ICAPP/SurveyUSA poll of 1,650 adults found 55% opposed data center construction in the state and 65% opposed tax breaks for it. Blue Rose Research found Americans would rather live near a prison or a nuclear plant than an AI data center. In Blue Rose's polling, AI ranked only 29th of 39 issues, but its importance to voters grew faster than any other issue over the past year.

Exit polls measure what voters say, not vote counts, and NBC kept revising its figures overnight. Treat these numbers as early.

What the results mean for AI stocks and the buildout

Markets reacted overnight. CNBC reported these moves:

• CoreWeave: down 7%
• SpaceX: down 7%
• Iren: down 6%
• Oracle: down 4.3%
• Nebius: down 3%
• Nvidia: slightly lower. Alphabet, Meta and Microsoft were mostly higher.

The reason is location. Wells Fargo estimates that about 27% of planned data center gigawatts in the US are in Texas. Wells Fargo strategist Ohsung Kwon had called a Democratic win a potential "left-tail event to the AI trade," meaning an unlikely outcome with a big downside. Bloomberg reports that the new Democratic governors could bring about half of US AI data center proposals under more scrutiny.

Ben Thompson of Stratechery argues that political opposition, not chips or power, is now the main limit on AI buildout. He thinks the opposition will last, because both parties now see it as a winning position. In his view this favors incumbents: hyperscalers that already have permitted sites, plus efficiency-focused chips and on-device AI. It hurts newer "neoclouds" and startups that still need new sites and permits.

The industry is already changing its pitch. According to Axios, as cited by Time, OpenAI plans a policy push that includes calling data centers "AI compute campuses." Elon Musk, the cycle's largest donor at about $446 million according to Time, posted after the results that "data centres in space" look appealing. (Euronews reported his total as $474 million.)

What's still unknown

• Final results. Kansas, Arizona and some local Ohio measures had not been called as of Wednesday morning.
• What a moratorium would actually look like in Texas. A governor's promise still needs legislation or agency action, and projects already under construction may not be affected.
• Federal action. Democrats won control of Congress. As Time notes, they would still need Republican support to override a presidential veto. A Carnegie fellow told Time that if Congress stays gridlocked, California may end up setting AI rules for the country.

What this means for you

If you live near a proposed data center, this election showed that local votes, zoning hearings and recalls can stop or reshape projects. Watch your city or township agenda for rezoning requests and tax-incentive deals. That's usually where these projects are decided.

If you use AI tools, nothing changes today. Existing data centers keep running, and the big providers have capacity under construction. The longer-term risk is slower growth in new capacity, which could keep AI compute expensive. Smaller providers that need new sites are more exposed than the largest companies.

If you hold AI stocks, expect more volatility around state policy news. This is not investment advice.

AI data centers midterms FAQ

Were data centers a big issue in the 2026 midterms?

Yes. The NBC News exit poll found 56% of voters called AI and data centers a crucial or major factor in their congressional vote, though AI ranked last of five issues asked about. Ballotpedia counted 41 data center measures on ballots in 10 states, and Democrats spent more than $100 million on ads tying opponents to Big Tech and data centers, according to Time.

Which Ohio cities voted to ban data centers?

Fortune reports that at least 14 Ohio municipalities passed bans or restrictions on November 3. Sunbury, Trenton and Pataskala approved bans on large data centers, Perry required financial guarantees from developers seeking tax breaks, and Wilmington rejected four rezonings. All five central Ohio communities with measures voted against data centers. Some results were still being counted on Wednesday.

Will Texas stop building data centers?

Not right away. Governor-elect Gina Hinojosa (a projected winner) has called for an immediate, temporary moratorium on new data centers until the legislature sets protections. Gov. Greg Abbott already paused new permits in September pending a grid audit. Projects already under construction may continue, and the details of any moratorium are not yet known.

How many data center ballot measures were there in 2026?

Ballotpedia counted 41 data center-related measures on the November 3, 2026 ballot across 10 states: 21 in Ohio, 7 in Illinois, 4 in Maine, 3 in Kansas and one each in six other states. 28 would limit development, including 17 bans, and 13 would make it easier, mostly through rezoning.

Why do people oppose AI data centers?

The most common reasons are higher electricity bills, water use, noise, the loss of farmland, tax breaks for large tech companies and deals negotiated in secret. In Ohio's ICAPP/SurveyUSA poll, environmental concerns came first, followed by quality of life and the economy. Opposition crosses party lines, researchers told Fortune.

Why did AI stocks fall after the election?

Investors worried that new limits would slow data center construction, especially in Texas, which holds about 27% of planned US data center gigawatts according to Wells Fargo. CNBC reported CoreWeave and SpaceX down 7%, Iren down 6% and Oracle down 4.3%. Large hyperscalers such as Alphabet, Meta and Microsoft were mostly higher.

What is Leading the Future?

Leading the Future is a pro-AI super PAC formed in August 2025 with more than $100 million to back candidates friendly to the AI industry. Time reports that its donations drew backlash, some promised donors backed away, and it mostly held back as the election approached. A linked group, Build American AI, ran at least $2.54 million in Ohio TV ads.

Will the election affect ChatGPT and other AI tools?

Not in the short term. Existing data centers keep running, and new rules mostly target future projects. Over time, slower approval of new campuses could limit how fast AI capacity grows, which could keep compute costs high. Analysts like Stratechery expect the biggest companies with permitted sites to cope best.
