Rankings
Biggest data center projects, largest operators, top states
The compute buildout, ranked by tracked capacity.
Three views over the same 727-facility dataset: the single largest projects by disclosed planned capacity, the operators with the most capacity across all their sites, and the states hosting the most capacity overall. Each ranking is ordered by tracked megawatts — not by press coverage or announcement size — and reflects only what a cited source discloses.
Every entry below links through to its full facility, operator, or state record and cited sources.
