A day after the midterm elections in the United States, the fight over the expansion of AI data centers gained a new chapter in Congress. On Wednesday, November 4, Senator Bernie Sanders, an independent from Vermont who caucuses with the Democrats, posted a direct appeal on X: a national moratorium on data centers — “National data center moratorium now.” The statement cited the local ballot measures of November 3, in which voters approved restrictions on data center projects in 40 of 41 measures, according to Ballotpedia.
It is important to be clear about what this is — and what it is not: so far, this is a political statement, not a law. No national moratorium is in effect. But the call adds to a movement that gained momentum after the Democratic victory on November 3, which gave the party control of the House and the Senate in the new Congress, which convenes on January 3, 2027.
What the moratorium bill proposes
The formal proposal already exists: the Artificial Intelligence Data Center Moratorium Act, introduced in the Senate as S. 4214 by Sanders on March 25, 2026, and in the House as H.R. 9442 by Representative Alexandria Ocasio-Cortez in June. The bill would halt the construction and expansion of covered AI data centers until Congress enacts safeguards on AI safety, labor, privacy, and civil rights.
The bill has not advanced beyond committee: it received no vote in either chamber, and only 22 members of Congress have signed on — Sanders has no co-sponsors in the Senate, and Ocasio-Cortez has 20 co-sponsors in the House. Because the bills were introduced in the 119th Congress, which ends in January, they would need to be reintroduced in the new Congress. Even with a Democratic majority, passage in the Senate would in practice require 60 votes to overcome a filibuster — Democrats held 54 confirmed seats as of November 6 — and President Donald Trump retains veto power.
Who supports the pause
Beyond Sanders, Representative-elect Yassamin Ansari of Arizona said pausing AI development should be a priority for the new Democratic House majority on day one, and Representative Greg Casar of Texas, chair of the Congressional Progressive Caucus, publicly backed the idea. In Texas, Governor-elect Gina Hinojosa pledged to halt approvals of new data centers until the state legislature passes protections for residents. The state holds about 27% of planned data center capacity in the United States, according to Wells Fargo.
At the state level, New York Governor Kathy Hochul had already created on July 14 the first statewide pause on environmental permits for new hyperscale data centers, for up to one year. Texas has also halted some permits while it carries out grid and water audits.
Market reaction and the industry’s response
The issue weighed on markets: the Nasdaq fell 5.5% on November 5 and entered a correction, and stocks tied to data centers and mining, such as IREN and Cipher Mining, dropped 14% to 16% the same day. Geekiki already covered the Nasdaq correction in an article on Nvidia’s drop and the Nasdaq correction.
The White House backs a different path: legislation to protect energy consumers — the House passed the Ratepayer Protection Act (H.R. 9340) by 417 votes to 3 on September 16. OpenAI, meanwhile, published a voluntary national compact on November 5 pledging to pay the full energy bill of its future campuses, as Geekiki reported on November 5. The compact, however, applies only to campuses the company owns and operates — and it is not a law.
What is fact and what is a statement: the national moratorium is, for now, a proposal and a political appeal, not a measure in force. No national pause has been approved, and the bill would need to be reintroduced, pass both houses of Congress, and survive a presidential veto. The statements by Sanders, Ansari, Casar, and Hinojosa are public positions, not official decisions.
