Artificial Intelligence Data Center Moratorium Act

Introduced·3/25/26

Overview

The Artificial Intelligence Data Center Moratorium Act establishes a comprehensive federal prohibition on the construction and upgrading of artificial intelligence data centers until Congress enacts legislation that adequately safeguards the public from AI-related dangers. The bill reflects growing concerns among technology leaders and policymakers about the rapid expansion of AI infrastructure without corresponding safety frameworks. By halting new data center development, the legislation creates a mandatory pause period designed to allow lawmakers to develop and implement comprehensive AI safety regulations before further infrastructure expansion occurs. The moratorium represents a precautionary approach to AI governance, prioritizing public safety over technological advancement until appropriate safeguards are established.

Core Provisions

The bill's central mechanism is a moratorium imposed under Section 3(b) that prohibits the construction or upgrading of new or existing artificial intelligence data centers. This prohibition remains in effect until two conditions are satisfied: first, one or more laws must be enacted that ensure the safety and well-being of the public from AI dangers, and second, those enacted laws must contain an express provision terminating the moratorium. The legislation also establishes export controls under Section 4, directing the Secretary of Commerce to prohibit the export, reexport, or in-country transfer of computing infrastructure hardware to countries lacking comparable AI safety laws or for specified end-uses that pose safety concerns. The bill incorporates the regulatory framework of the Export Control Reform Act of 2018 as the statutory foundation for these export restrictions. Section 3(c) mandates quarterly reporting requirements for AI data centers, requiring detailed information about their operations, capacity, and compliance status.

Key Points

  • Moratorium on construction and upgrading of AI data centers until safety legislation is enacted [§3(b)]
  • Moratorium terminates only when new laws expressly provide for termination [§3(b)(2)]
  • Export controls on computing infrastructure hardware to countries without comparable laws [§4(b)(1)]
  • Quarterly reporting requirements for AI data center operations [§3(c)(1)]
  • Prohibition applies to both new construction and upgrades of existing facilities [§3(b)]

Implementation

Implementation authority is divided between the Secretary of Energy and the Secretary of Commerce, with the Energy Secretary overseeing the domestic moratorium and reporting requirements while the Commerce Secretary administers export controls on computing hardware. The Secretaries are granted extensive enforcement powers under Section 3(c)(3), including authority to issue subpoenas, conduct written interrogatories, perform inspections of data center facilities, and condition future permitting on compliance with reporting requirements. The quarterly reporting mechanism requires data centers to provide comprehensive information about their operations, though the specific contents of these reports are detailed in subsection 3(c)(2). The enforcement framework relies on both administrative oversight and the conditioning of future permits, creating a compliance incentive structure that extends beyond the moratorium period itself.

Key Points

  • Secretary of Energy administers domestic moratorium and reporting requirements
  • Secretary of Commerce controls export restrictions on computing hardware
  • Enforcement through subpoenas, interrogatories, and facility inspections [§3(c)(3)]
  • Future permitting conditioned on compliance with reporting requirements
  • Quarterly reporting cycle for all covered AI data centers [§3(c)(1)]

Impact

The moratorium directly affects the artificial intelligence industry by halting all new data center construction and upgrades, creating immediate operational constraints for technology companies planning infrastructure expansion. Computing infrastructure hardware manufacturers face export restrictions that limit their ability to sell products internationally, particularly to countries without comparable AI safety legislation. The bill imposes significant compliance burdens on existing AI data centers through quarterly reporting requirements and potential facility inspections. The economic impact includes delayed capital investments in AI infrastructure, potential job losses in data center construction, and reduced competitiveness for U.S. technology companies in global AI development. The legislation contains no sunset provision, meaning the moratorium continues indefinitely until Congress enacts qualifying safety legislation with an express termination clause. This creates substantial uncertainty for long-term business planning and infrastructure investment in the AI sector.

Key Points

  • Immediate halt to all new AI data center construction and facility upgrades
  • Export restrictions limiting international sales of computing hardware
  • Quarterly compliance burden on existing AI data center operators
  • Indefinite duration with no automatic sunset provision
  • Potential competitive disadvantage for U.S. technology companies globally

Legal Framework

The bill operates under Congress's constitutional authority to regulate interstate commerce and national security through export controls. The export control provisions explicitly incorporate the Export Control Reform Act of 2018 as their statutory foundation, providing established legal mechanisms for restricting technology transfers. The moratorium on data center construction represents an exercise of federal regulatory power over commercial activity with national implications. The legislation appears to preempt state and local authority over AI data center permitting during the moratorium period, as the federal prohibition supersedes any state or local approvals that might otherwise authorize construction. The bill does not explicitly address judicial review provisions, leaving challenges to the moratorium subject to general administrative law principles under the Administrative Procedure Act. The enforcement mechanisms, including subpoena power and inspection authority, must comply with Fourth Amendment protections against unreasonable searches and due process requirements under the Fifth Amendment.

  • U.S. Constitution, Fifth Amendment (due process requirements)

Critical Issues

The bill faces significant constitutional challenges regarding its indefinite prohibition on commercial activity without clear standards for termination. The requirement that future legislation must expressly terminate the moratorium creates a legislative entrenchment problem, as one Congress cannot effectively bind future Congresses. The lack of definition for what constitutes adequate safety legislation creates uncertainty and potential for indefinite extension of the moratorium. Implementation challenges include defining which facilities qualify as artificial intelligence data centers versus general-purpose computing facilities, determining the scope of prohibited upgrades to existing facilities, and establishing verification mechanisms for export control compliance. The bill's economic implications are substantial, potentially driving AI development offshore to countries without similar restrictions and disadvantaging U.S. companies in global competition. The absence of any emergency exception or national security waiver creates inflexibility that could prove problematic if urgent AI infrastructure needs arise. Opposition arguments center on the bill's potential to cede American leadership in AI technology, its vague termination conditions, and the practical impossibility of achieving consensus on comprehensive AI safety legislation that would satisfy the moratorium's requirements.

Key Points

  • Constitutional concerns about indefinite commercial prohibition without clear standards
  • Legislative entrenchment issue requiring express termination in future laws
  • Definitional ambiguity regarding what constitutes an AI data center
  • Risk of driving AI development to foreign jurisdictions without restrictions
  • Absence of emergency exceptions or national security waivers
  • Practical difficulty of achieving consensus on qualifying safety legislation
  • Potential violation of due process through vague termination standards
