Understanding This Ranking
Capacity means published IT load, not total site power
Megawatt figures reflect the best publicly available data for each facility. Some operators report total site power, others report IT load only. Treat the numbers as approximate and directionally useful, not perfectly comparable.
Not all facilities disclose capacity
9 tracked facilities do not have published capacity data and are excluded from this ranking. The actual largest facilities globally may include sites that have not yet disclosed their power draw.
Planned and announced capacity is included
This ranking includes facilities that are operational, under construction, planned, and announced. Check the status column to distinguish live capacity from pipeline projects.

Frequently asked questions
- 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 46 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, India, France. The United States leads in both number of facilities and total capacity, driven by hyperscaler investment.
- How is AI data center capacity measured?
- Capacity is measured in megawatts (MW) of IT load — the power available to computing equipment. Some operators report total site power including cooling overhead, while others report IT load only. Figures in this ranking reflect the best publicly available data and should be treated as approximate.
