The Largest AI Data Centres in the World
The frontier AI build-out is measured in megawatts. These are the largest disclosedAI data-centre campuses on Earth — 40 that are online and ranked by current power, plus 10 more that are announced or under construction. The tracked set totals around 9,427 MW of capacity. Figures are estimates from Epoch AI.
Ranked by current power
Announced & under construction
Tracked campuses whose power is not yet online — they carry no capacity figure until they come up.
About this ranking
This ranks the largest disclosed AIdata-centre campuses — the hyperscale sites driving the AI electricity-load surge — not every data centre on Earth. It comes from Epoch AI’s curated Frontier Data Centers tracker (CC BY): 60 campuses in all, of which 40 are online with a disclosed megawatt figure, 10 are announced or under construction, and 9lack a precise public address. Power, compute and cost are Epoch estimates, and the set is currently US-heavy — a real fact about where frontier compute is being built. Snapshot taken 2026-06-24.
