Moratorium on AI Data Centers: Ocasio-Cortez and Sanders Challenge U.S. Compute Expansion

Context

On June 25, 2026, Alexandria Ocasio-Cortez and Bernie Sanders introduced the AI Data Center Moratorium Act, aiming to freeze all new permits for AI-dedicated data center construction in the United States. This marks the first federal legislative initiative directly targeting the physical and energy footprint of artificial intelligence. Global data center consumption is expected to reach 945 TWh in 2026 according to the IEA (Electricity 2025)—with the United States accounting for nearly 40%, or ~380 TWh, a more than 100% increase since 2020.

Data

• U.S. data center electricity demand reached 176 TWh in 2023 (DOE, 2024).
• The seven largest hyperscalers (Microsoft, Google, Amazon, Meta, Apple, Oracle, xAI) have announced $600+ billion in cumulative data center CAPEX for 2025-2027.
• CoreWeave signed a $355 million storage deal with Backblaze (06/24); Argentum AI raised $4.1 billion for 27,000 GB300 GPUs.
• The share of nuclear in hyperscalers' PPAs has doubled in 18 months: 23% of new agreements (Wood Mackenzie, Q1 2026).

Analysis

The mechanism is a classic input/output bottleneck: AI compute demand is growing exponentially (+300% in 3 years for H100/B200 GPUs), but the electrical grid infrastructure is not keeping pace. PJM Interconnection (U.S. East Coast grid) has a backlog of 290 GW with delays of 7 to 12 years. A moratorium—even symbolic—injects regulatory risk premiums into CAPEX projections and compute players' valuations.

Probabilistic Scenarios

• Scenario A - Legislative Rejection (65%): Republican Congress blocks. Pressure from states (California, New York) intensifies within 18 months.
• Scenario B - Partial Adoption (25%): Energy criteria (renewable share ≥ 60%) imposed for federal permits. Advantage for operators committed to green PPAs (Google, Microsoft).
• Scenario C - EPA Precursor Effect (10%): EPA regulations on data center emissions → CAPEX shock for CoreWeave, Equinix, and Digital Realty.

Portfolio Implications

Data center REITs (Equinix EQIX, Digital Realty DLR) face short-term regulatory risk discounts. Nuclear providers (Constellation Energy CEG, Vistra VST) gain a structural competitive advantage. Pure-play GPU cloud providers with weak balance sheets (CoreWeave) remain most exposed to any permitting constraints.

Risks & Blind Spots

Backed by progressive senators in a dominant deregulatory context, the bill has little chance of passing in the short term. However, it sets a political precedent that could accelerate state-level measures within 12-18 months. Utilities (Constellation, NextEra), which view data centers as a welcome captive demand, will actively oppose it.

To Monitor

• DOE and FERC response within 30 days of filing.
• Three Mile Island Unit 1 nuclear permit (Microsoft PPA, operational since Q1 2026).
• PJM backlog reform (Q3 2026).
• Positions of senators from states with heavy data center presence (Virginia, Texas, Ohio).
