Top 10 largest AI Datacenters in 2026

Summary

The video ranks the ten largest AI data centers by installed megawatt as of early 2026, highlighting historic construction speed and massive power consumption. It covers XAI, OpenAI, AWS, Microsoft, Meta, and Google sites, with Google's Columbus, Ohio and Omaha, Nebraska campuses taking the top two spots. The speaker argues the AI data center buildout is still accelerating, with many sites expanding into the gigawatt range and 500 MW soon insufficient to lead the ranking.
