Frequently Asked Questions

What is the largest data center in the world?

Among the facilities Data Center List tracks, the largest is Hyperion in United States at 5.00 GW of IT power capacity (publicly disclosed). This reflects our tracked coverage, not a claim of global completeness — many large facilities never publish capacity figures.

What is the largest data center with a publicly disclosed capacity?

The largest facility with a publicly disclosed (non-estimated) power figure in our dataset is Hyperion in United States at 5.00 GW. This is a measured/reported figure, not a model estimate.

How does Data Center List rank data centers by size?

We rank by IT power capacity in megawatts (MW), the standard industry measure of a facility's compute capacity — not building square footage. Rankings are split into two lists: facilities with a publicly disclosed capacity figure, and a broader list that also includes AI-estimated capacity (flagged with an 'AI est.' badge) for facilities that don't publish numbers.

Are AI-estimated data center capacities accurate?

AI estimates are modeled from published research (industry power-density studies, operator disclosures for comparable facilities) calibrated to each facility's known attributes, and are always flagged with an 'AI est.' badge. They're directional, not measured — treat the 'Largest disclosed capacity' list as the more reliable ranking, and estimates as an illustrative, broader view.
