The World's 10 Largest Data Centers · Eight Are American

Colossus 2 leads at roughly 1.3 million H100-equivalents, with OpenAI's Stargate at Abilene, Texas second at about 1.05 million and the Anthropic-Amazon site at New Carlisle, Indiana third at about 730,000. Eight of the ten are in the United States; the exceptions are two DayOne sites in Johor, Malaysia. The tenth, Google Columbus, is about a quarter the size of the first.

Horizontal bar chart of the world's ten largest data centers in 2026 by estimated compute in H100-equivalents, from Colossus 2 at about 1,300,000 down to Google Columbus at about 310,000. OpenAI Stargate Abilene in Texas is highlighted in amber at about 1,050,000. Two Malaysian sites, DayOne Nusajaya and DayOne Kempas, are the only entries outside the United States. — The ten largest data centers by estimated compute, 2026, in H100-equivalents.

Why this matters for B2B

Before a site like this computes anything it is a construction project running for years: earthworks, steel, electrical, cooling, fencing, then the fit-out and the supply chain that keeps it running. That is the part a wholesaler sees. A build of this scale also pulls in contractors, temporary housing and a service economy around a town that did not have one. Texas already carries the second largest of these, and more are coming — read U.S. data centers under construction by state, a $1B pharma base eyeing Houston and the Texas market.
