What we know
At around 490 MW, Colossus 2 is among the most power-hungry computing sites ever built, with an estimated 555,836 H100-equivalent accelerators of compute and a build cost estimated near $18.6 billion. These are estimates from Epoch AI’s Frontier Data Centers tracker (CC BY) — a curated set of the largest disclosed AI campuses, not a census, and currently US-heavy. This campus is located to a precise, published location (35.00, -90.03). Power, compute and cost figures are Epoch estimates that change as sites are built and disclosed. Snapshot taken 2026-06-24.
