**Deck**: Record spending of around $750 billion on artificial intelligence infrastructure in 2026 has not prevented the first slowdown in US data center construction since 2020, as electricity emerges as the main structural barrier.

The expansion of the physical infrastructure behind artificial intelligence in the United States is starting to hit hard limits, even as investment reaches unprecedented levels.

According to a forwarded briefing, record investments in artificial intelligence infrastructure in 2026 — around $750 billion — have not translated into an uninterrupted building boom. Instead, the pace of data center construction in the US has declined for the first time since 2020.

The industry now faces constraints across multiple fronts, with electricity described as the most acute structural barrier. Data centers currently consume about a significant share of available power, and the next generation of AI-focused facilities will demand even more.

This puts the sector at odds with the capacity of local grids, transmission networks, and permitting systems to deliver enough electricity where and when it is needed. Without sufficient power, new data centers cannot operate at full load, regardless of how much capital has been committed to hardware and buildings.

For operators and their customers, the slowdown marks a shift from financial to physical limits: the ability to secure reliable, large-scale power connections is becoming as important as access to cutting-edge chips.

How quickly utilities, regulators, and developers can resolve these bottlenecks — through grid upgrades, new generation, or changes in where and how data centers are sited — will determine whether AI infrastructure growth in the US can resume its previous pace.
