Data center opponents have blocked or delayed projects worth nearly $130 billion in 2026, study finds

The first quarter of 2026 produced the most blocked and delayed data center projects on record, according to a new study shared with NBC News.

The study — conducted by Data Center Watch, a project of the AI intelligence firm 10a Labs that tracks local data center activity — found that data center opponents blocked or delayed at least 75 projects nationwide worth about $130 billion from January through March, the most in a three-month period since the group began tracking in 2023.

“The quarter reflected a structural shift rather than a cyclical spike: communities have internalized an opposition playbook, legislative sessions introduced formal regulatory uncertainty, and the number of active opposition groups more than doubled to 833 across 49 states,” the authors wrote, noting that the total number and value of data centers blocked or delayed during the first three months of 2026 roughly matched the total for all of 2025.

Data center construction has become a major political issue, with groups of residents opposed to the effects the large developments have on energy consumption and the environment, among other concerns. Leaders in both parties, who largely welcomed the investments in their states, are recalibrating their approaches.

Data center proponents, meanwhile, have said the concerns are overblown or based on faulty data and have promoted the economic benefits generated by the developments, which are needed to power the AI boom.

The report found that legislative pushes for moratoriums on constructing data centers ballooned during the first quarter of 2026, sponsored by lawmakers on both sides of the aisle. The report found such proposals introduced in 14 states from January through March, with Sen. Bernie Sanders, I-Vt., and Rep. Alexandria Ocasio-Cortez, D-N.Y., introducing a federal version.

Though none of the proposals has been signed into law, one did reach the desk of Democratic Gov. Janet Mills in Maine. She vetoed it in April.

More than 300 bills were introduced in statehouses across the country just in the first six weeks of 2026, the authors found, saying it marked “a clear shift from incentive-focused policies toward regulatory oversight as the scale of energy demands became clearer.”

What’s more, the study found that the number of active grassroots opposition groups across the country more than doubled from 396 at the end of 2025 to 833 by March. The authors found that the states with the most opposition groups through that month were Maryland, Ohio and Texas.

“In some cases,” they wrote, “opposition mobilized before any project was officially filed, the mere rumor of a data center was enough to trigger organized resistance.”
