Read twice and referred to the Committee on Commerce, Science, and Transportation.

What it does
This bill would impose a moratorium on constructing or upgrading large artificial intelligence data centers (generally those over 20 megawatts or used for AI development at scale) until Congress enacts laws covering federal pre-approval of AI products, worker protections against job displacement, and specific conditions for future data centers such as no electricity bill increases, community veto power, no government subsidies, and union labor standards. It also directs the Commerce Department to restrict export of semiconductors and computing hardware to countries lacking comparable AI safety laws, and requires the Department of Energy to publish quarterly reports on data center operations, finances, and environmental impacts.
Who benefits
Communities near planned data centers concerned about electricity costs, water use, and noise; construction and utility workers who might gain from union labor requirements if the moratorium is later lifted; organized labor groups seeking prevailing-wage and apprenticeship mandates; environmental advocates concerned about energy and water consumption; workers whose jobs could otherwise be displaced by AI, according to proponents.
Who is hurt
Technology companies (including Amazon, Google, Microsoft, Meta, and smaller AI firms) that would be unable to build or expand data centers; construction firms, electricians, and contractors currently employed on data center projects; utilities and localities that rely on data center investment and tax revenue; U.S. semiconductor and hardware exporters facing new restrictions; researchers and startups dependent on cloud computing capacity, who may face reduced access as capacity growth halts.
Supporters argue
Supporters argue that AI development is advancing faster than regulatory and safety frameworks can keep pace, citing statements from AI industry leaders like Dario Amodei and Geoffrey Hinton warning of catastrophic risks including mass job displacement and loss of human control. They contend that pausing physical infrastructure buildout now — before further lock-in of environmental, labor, and economic harms — gives Congress leverage to enact enforceable safeguards on AI products, worker protections, and equitable distribution of AI-generated wealth before the technology becomes further entrenched.
Opponents argue
Opponents argue that a blanket moratorium on data center construction would freeze investment critical to national competitiveness in AI, cede ground to countries like China that face no such restriction, and cost thousands of construction and technology jobs immediately rather than hypothetically. They contend the bill's conditions for lifting the moratorium — including a ban on any subsidies and mandatory union labor agreements — are so restrictive that the pause could become effectively permanent, and that Congress imposing federal pre-approval of all AI products before release raises serious concerns about stifling innovation and free expression.
Constitutional context
Congress's power to regulate data center construction and hardware exports rests on the Commerce Clause (Art. I, §8, cl. 3), and the export control provisions implicate the President's foreign affairs and national security authority under Article II; the federal pre-approval requirement for AI "products" before release could raise First Amendment prior-restraint concerns depending on how "products" is defined, an issue not yet addressed by the Supreme Court in this context.
Checks and balances
Congress would set the moratorium's terms and its termination conditions in statute, while the Secretary of Energy and Secretary of Commerce would gain significant new enforcement and export-control authority, including subpoena power, with judicial review available to affected companies under the Administrative Procedure Act.
Historical precedent
There is no directly analogous federal moratorium on a specific category of commercial construction tied to future legislative conditions, though export controls on sensitive technology to certain countries have precedent in existing semiconductor export restrictions under the Export Control Reform Act.
