How many data centres are there in the world?

There are approximately 11,000+ commercial colocation and hyperscale data centres globally as of 2026, with the total growing at 15% per year. The United States dominates with roughly 40% of global capacity, followed by Europe (25%), Asia-Pacific (25%), and the rest of the world (10%). The top five markets by power capacity are Northern Virginia (4,000+ MW), Dallas-Fort Worth, Phoenix, Chicago, and London. Including enterprise-owned facilities, the total number exceeds 50,000 worldwide. However, the trend is toward consolidation — fewer, larger facilities replacing many small server rooms. Over the past decade, the number of enterprise-owned data centres has declined 30% while total capacity has tripled.
