What is the largest AI data center in the world?

Based on published capacity data, Wonder Valley Off-Grid AI Data Center Park is currently the largest tracked AI data center at 7.5 GW. However, not all facilities disclose their power capacity, so the true largest may differ.

How many gigawatt-scale AI data centers exist?

The index currently tracks 27 facilities at or above 1,000 MW (1 GW). This includes operational sites, facilities under construction, and announced projects. The number is growing rapidly as hyperscalers scale up their AI infrastructure.

Which countries have the largest AI data centers?

The countries with the most large-scale AI data centers include United States, Germany, South Korea, Japan, United Kingdom. The United States leads in both number of facilities and total capacity, driven by hyperscaler investment.

How is AI data center capacity measured?

The ranking uses the selected public MW value for each record. Where available, ADCI prefers IT load, measured system power, or directly attributable compute-system draw; when those are unavailable, the selected value may be facility power, grid connection, program capacity, or another scoped public disclosure.
