Common questions

What is the biggest AI data center?

By announced capacity, the largest campus DEPLOY tracks is Fermi America HyperGrid (Project Matador) at about 11 GW announced, of which roughly 0 GW is energized today. Announced size and running size are different facts, and both are shown.

Why rank by announced instead of energized?

Because most of the largest sites are still being built, so their energized capacity is near zero. Announced gigawatts is the honest way to rank ambition, but energized is shown in the same row so a plan is never presented as an operating facility.

Are these campuses or buildings?

Campuses. Only the flagship campus tier carries a gigawatt ledger. The wider colocation and hyperscale facilities are counted in the US total and the operator and state rankings, but they are ranked by count and IT capacity, not gigawatts.

How is each figure verified?

Every capacity figure carries an evidence tier (verified, reported, or claimed), an as-of date, and a primary source. The current-best figure resolves to the highest tier then the latest date, excluding superseded claims. The methodology page has the full rule.
