Data Center Backlash: 183 U.S. Towns Enact Moratoriums as Industry Looks to Ocean and Space
Summary
- • 183 U.S. towns have enacted data center moratoriums or bans; 142 protests held across 42 states on July 18.
- • 70% of Americans oppose AI data centers in their local areas, per a March 2026 Gallup poll.
- • Startup Panthalassa raised $225M at ~$2B valuation for ocean-based, wave-powered floating data centers.
- • YC startup Starcloud launched the first space-based LLM training facility in November 2025; second satellite launches October 2026 with 100x capacity.

183 U.S. town moratoriums
According to the U.S. Data Center Moratorium Tracker, 183 American towns have enacted data center moratoriums or outright bans as of mid-2026.
142 protests across 42 states on July 18
On July 18, 2026, 142 coordinated protests were held across 42 U.S. states against data center construction — signaling organized national opposition, not isolated local complaints.
70% public opposition (Gallup)
A March 2026 Gallup poll found 70% of surveyed Americans oppose AI data center construction in their local areas, citing electricity and water demands, noise, and unfulfilled job creation promises.
Panthalassa ocean-based data centers
Portland-based Panthalassa is developing Ocean-3, an orb-shaped data center floating hundreds of miles into the Pacific, generating power via pressurized seawater turbines and using natural ocean cooling to eliminate water consumption entirely.
Panthalassa: $225M raised, ~$2B valuation
Panthalassa has attracted $225 million in funding and a nearly $2 billion valuation before its Ocean-3 system has launched commercially.
Shanghai Lingang undersea center operational
China's Shanghai Lingang undersea data center, six miles off Shanghai's coast, uses 95% green electricity, reduces power consumption by 22.8%, and achieves 100% water savings via natural ocean cooling. Received $226M in investment as of October 2025.
Starcloud: first space-based LLM training
YC startup Starcloud launched Starcloud-1 in November 2025 — the first facility to train an LLM in space — using solar energy and vacuum cooling to achieve 10x lower energy costs despite launch expenses.
Starcloud-2 launches October 2026 with 100x capacity
Starcloud's second satellite, set to launch October 2026, will have 100 times the power-generation capacity of its predecessor, marking a rapid scale-up in space-based compute infrastructure.
Industry seeking unusual real estate
Domestic and international AI companies are exploring offshore, undersea, and orbital locations as local moratoriums and organized opposition make traditional land-based data center siting increasingly difficult in the U.S.

What This Means
The wave of U.S. data center moratoriums has crossed from local nuisance to structural industry constraint. With 183 towns blocking development, 70% public opposition, and organized national protests, AI infrastructure planners can no longer treat community resistance as a solvable permitting problem. The emergence of ocean-based and space-based alternatives — while not yet at commercial scale — demonstrates that the industry is beginning to treat geography itself as a design variable rather than a given. This community pushback may prove as consequential to AI's near-term infrastructure trajectory as chip supply constraints or regulatory pressure, forcing a fundamental rethink of where and how AI compute is built.
