- Sen. Bernie Sanders and Rep. Alexandria Ocasio-Cortez introduced the AI Data Center Moratorium Act on March 25, 2026, proposing a federal halt to new large-scale AI data center construction.
- The moratorium could only be lifted after Congress passes laws addressing AI product safety, equitable wealth distribution from AI gains, and environmental protections.
- The bill would also ban exports of advanced computing hardware to countries lacking equivalent AI regulations.
- Lawmakers in at least 11 states have separately proposed data center construction pauses, reflecting growing local opposition.
What Happened
Sen. Bernie Sanders (I-VT) and Rep. Alexandria Ocasio-Cortez (D-NY) introduced the AI Data Center Moratorium Act on March 25, 2026, legislation that would impose an immediate federal ban on new large-scale AI data center construction and upgrades. The moratorium would remain in effect until Congress enacts federal legislation meeting three specific regulatory requirements.
Sanders framed the bill as a necessary pause for democratic governance. “A moratorium will give us time — time to understand the risks, time to protect working families, time to defend our democracy and time to ensure that this technology works for all of us, not just the few,” Sanders stated in the announcement.
Why It Matters
The bill arrives amid escalating tensions between AI infrastructure expansion and community opposition. Lawmakers in at least 11 states have proposed their own data center construction pauses, according to the National Conference of State Legislatures, and multiple data center projects have been abandoned due to local resistance.
An NBC News poll found that 57% of registered voters believe the risks of AI outweigh its benefits, with 33% trusting neither party to handle AI policy effectively. Ocasio-Cortez cited this public anxiety directly: “Congress has a moral obligation to stand with the American people and stop the expansion of these data centers until we have a framework to adequately address the existential harm AI poses to our society. We must choose humanity over profit.”
Technical Details
The legislation sets three categories of conditions that must be met before the moratorium can be lifted. The first requires federal review of AI products before release to ensure they “do not threaten the health and well-being of working families, privacy and civil rights, and the future of humanity.”
The second category mandates legislation ensuring that “the economic gains of artificial intelligence and robotics will benefit workers, not just the wealthy owners of Big Tech companies,” including policies to prevent AI-related job displacement and require wealth-sharing with the public.
The third addresses environmental protections, requiring that data centers not increase utility costs for surrounding communities, that they prevent climate harm, that communities retain authority to reject proposed facilities, that public subsidies be prohibited, and that construction jobs be union positions.
A separate provision would direct the Commerce Department to prohibit exporting advanced computing infrastructure hardware to countries that lack equivalent regulatory frameworks.
Who’s Affected
Major technology companies planning data center expansions in the United States would face the most direct impact, including Microsoft, Google, Amazon, and Meta, all of which have announced multi-billion-dollar AI infrastructure buildouts. Communities near proposed data center sites, particularly those concerned about energy costs, water usage, and noise, are the intended beneficiaries.
The bill contrasts sharply with the Trump administration’s AI framework, which has pushed for streamlined permitting and preemption of state regulations on data center construction. President Trump has encouraged AI companies to voluntarily pledge to “pay their way” for data centers’ substantial energy requirements, an approach Sanders and Ocasio-Cortez view as insufficient.
Workers in data center construction and adjacent industries would also be affected. The bill’s requirement for union jobs on data center construction projects aims to ensure that any future building, once the moratorium is lifted, includes labor protections.
What’s Next
The legislation is unlikely to advance under the current Republican-controlled Congress, but Sanders and Ocasio-Cortez appear to be positioning it as a midterm election platform issue. Democrats see public skepticism toward AI and data center expansion as a potential campaign advantage.
The bill’s practical significance lies less in its legislative prospects than in its role as a marker of growing political opposition to unchecked AI infrastructure growth. With 11 states already pursuing their own construction pauses, federal legislation may eventually follow if local momentum continues to build. For now, the moratorium remains a statement of intent rather than an imminent policy change.
