Epoch AI scales data center research to cover 46% of global compute capacity

If you wanted to understand the sheer scale of AI infrastructure being built around the world, you used to be stuck stitching together press releases, earnings calls, and educated guesses. Epoch AI just made that job significantly easier. The independent research organization’s AI Data Centers database now tracks 86 large facilities globally, covering an estimated 46% of all deployed AI compute as of June 2026. That’s roughly double the coverage from early 2024, when the figure sat around 22%. The tracked sites carry a combined IT power capacity of approximately 13.3 gigawatts and house an estimated 13.9 million H100-equivalent GPUs. What’s inside the database Epoch’s database focuses on high-capacity, AI-optimized sites rather than traditional enterprise data centers. The methodology combines satellite imagery with public documents to build detailed timelines covering power consumption, computing capabilities, and construction progress for each facility. The biggest entries read like a leaderboard for the AI arms race. SpaceXAI’s Colossus 2 tops the list with roughly 1.112 million H100-equivalent GPUs. Microsoft’s Fairwater Atlanta facility follows at approximately 769,000 H100-eq...
