- Voters in 10 US states decided local questions about data centres on November 3.
- One early count shows 33 limits approved and one measure allowing data centres.
- A candidate who promised a moratorium won in Texas, but that is still only a promise.
- The numbers are unofficial, and some votes only show what voters think.
- Data centre
- A large building full of computers, used to train and run AI and other services.
- Moratorium
- A temporary halt, here on building new data centres or giving them permits.
- Advisory vote
- A vote that shows what people want but does not bind local officials.
A data centre is a large building full of computers, and AI has set off a building boom. Local fights over these projects often turn on power bills, water and secret deals, Route Fifty reports. On November 3, many of those fights went directly to voters.
What was on the ballot
Ballotpedia, which tracks US elections, counted 41 local measures in 10 states before the vote. Ohio had 21, Illinois had seven, Maine had four and Kansas had three.
A “yes” on 28 of them would limit data centres. Seventeen of those were bans, and three were six-month moratoriums, or temporary halts. A “yes” on the other 13 would help building, for example through zoning. Nine measures were non-binding, so they only show what voters think.
Other counts differ. Route Fifty counted 40 votes, and Tom’s Hardware cites trackers with 45 and 46 measures. The reports don’t explain the gaps.
Early, unofficial numbers. Each line names who reported it.
The early results
By 8 a.m. Eastern Time on November 4, voters had approved 33 measures restricting data centres and one allowing them, according to Redbud Consulting, Business Insider reports.
Tom’s Hardware, citing the Data Centers on the Ballot tracker, reported 33 restrictions won, six more leading and one lost. Five had no posted results. A second tracker showed 11 of 13 measures that favour data centres on course to fail.
The restriction that lost was in Harwood, North Dakota. There, 75% of the 430 voters rejected a charter change, the secretary of state’s office said, Route Fifty reports. It would have required an independent review and a public hearing for large projects.
All these numbers are early and unofficial, so they can still change.
Where voters said no
Almost 20 towns, cities and counties in Ohio held votes, and data centre opponents appear to have won every race, Route Fifty reports.
In Ashville, Ohio, 82% of 1,800 voters rejected a resolution to go ahead with data centres and a gas plant, Business Insider reports. In Trenton, a ban passed 80% to 20%. In Wilmington, about 80% rejected rezoning in four separate votes, Fortune reports.
In Emporia, Kansas, just over 60% backed a ban on centres that need more than 10 megawatts of power or 100,000 gallons of water a day, Route Fifty reports. In Alhambra, California, a ban was on track with 82%, with many votes still to be counted.
Texas, and the AI question
In an NBC News exit poll, 76% of voters said they would oppose a new data centre in their community. And 56% called AI and data centres a crucial or major factor in their vote for Congress, Business Insider reports.
In Texas, Democrat Gina Hinojosa beat Governor Greg Abbott, with a 7-point lead when 96% of votes were counted, the Associated Press reported. “We need an immediate moratorium on data centers to last until the legislature can meet,” the campaign’s website says.
That is still a promise. Democrats are on track to control the Texas House, but the state Senate appears set to stay Republican, Yahoo Finance reports. Texas accounts for more than 25% of planned US capacity by 2030, it adds.
The measures name data centres, not AI, and Emporia’s wording could also cover cryptocurrency mining, Route Fifty notes. “A lot of this comes down to the public’s fear of AI, and this is the tool they have to fight,” Republican strategist Rob Stutzman told Politico.
What comes next
Goldman Sachs economists expect “short-term data center moratoria, potentially affecting about 45% of planned US data center capacity expansion,” Business Insider reports.
It is unclear how far the votes will touch projects already under way, Tom’s Hardware notes. Harwood’s measure, for example, would not have covered the Applied Digital campus already approved there.
More votes are coming. Voters in Clarksville, Arkansas, will decide on December 1 whether to approve bonds linked to data centres, Smart Cities Dive reports. Backers of an Ohio constitutional ban on large data centres hope to reach the ballot next year.

Voters approved 33 local restrictions against one measure allowing data centres, and moratoriums could touch about 45% of planned US capacity growth. How we rate the mood
The mood shows how the news frames the event for the tech and AI world: as an opportunity (6 and above) or as a loss (below 5). It is not our verdict on who is right.
