Moody’s warns data center boom is becoming a credit risk for state governments

The data center building boom has a hangover, and state and local governments are the ones nursing it. Moody’s Ratings released a report in June 2026 warning that the rapid expansion of data centers across the US is driving up credit risks for public entities struggling to absorb the infrastructure demands that come with it.

The core problem is simple: data centers need enormous amounts of electricity and water, and the public systems built to provide those resources were not designed with hyperscale AI workloads in mind.

What Moody’s actually said

The June 2026 report draws a direct line between the surge in data center construction and elevated fiscal pressure on state and local governments. The growth is being fueled by advances in artificial intelligence, cloud computing, and data storage, with pre-leased capacity going predominantly to hyperscalers, the handful of giant tech companies building at a scale that would have seemed implausible a decade ago.

Moody’s had already flagged the water side of this equation back in April 2026, noting that data centers’ water demands were increasing management risks and capital needs for local governments, particularly in markets already dealing with resource constraints. The June report expanded that concern to electricity infrastructure and the broader credit picture.

Key drivers for where data centers get built, according to Moody’s, include power access and cost, fiber connectivity, and natural disaster exposure. That means the jurisdictions most attractive to developers are often the ones already operating closer to their infrastructure limits.

Fourteen states and the moratorium question

At least 14 states are considering statewide moratoriums in 2026 to pause and assess the impact of data center expansion before committing to long-term policy.

Not every state is hitting pause. Michigan and West Virginia have moved in the opposite direction, enacting incentives to pull data center investment toward their regions.

What this means for investors

For anyone holding municipal bonds or watching credit spreads in infrastructure-heavy regions, Moody’s is waving a flag worth taking seriously. The moratorium movement in 14 states introduces a layer of regulatory risk that could affect project timelines and the tax revenue projections that local governments have already baked into their budgets. A data center that gets delayed or cancelled does not generate the property tax revenue a city was counting on to justify the grid upgrades it already approved.
