What this directory covers

What is in it

Large AI data center campuses in the United States tracked by Epoch AI: the biggest sites run by Google, Meta, Microsoft, Amazon, OpenAI and its partners, xAI, CoreWeave, Anthropic and others. Each has an owner, location, power, cost estimate and a dated timeline.

What is not in it

It is not every data center. The US has thousands of smaller colocation, enterprise and government facilities, and trackers count them differently. Pew Research counts Virginia (287), Texas (170), Georgia (141), Illinois (123) and Arizona (86) as having the most planned data centers, and that count includes sites that are only land-banked.

It also has no early-stage plans that have not started construction, apart from the seven we added by hand from news reports, so "planned" is still a sample, not a full list. Planned sites are the ones most likely to change or be dropped.
