How to read this list

Ranked by sites tracked, not by power capacity. A site counts once, under the name its source gives. Another ranking may use capacity or area and order the same names differently.
Operating is a site that is open. Planned is a site that is not open yet: announced, planned or under construction. The two are shown in separate columns and are never added together.
Counts are sites recorded, not a census of the data center market in the United States, and they grow as coverage grows. Power capacity is reported for only some sites, so a blank means not reported, not zero.

How this data is built

Real Assets reads company pages, filings, news and listings, and records figures with a link to the page that published them.

Counts are sites Real Assets has recorded, not a full census, and grow as coverage grows. Sites are listed with the operator as published (the owner for industrial parks). Data updated 20 October 2026.

Questions

How are United States data center operators ranked?

By sites tracked: the number of sites Real Assets has recorded under each operator's name, as the source gives it. It is not a ranking by power capacity, so a list ranked that way can put the same names in a different order. Operating is a site that is open. Planned is a site that is not open yet: announced, planned or under construction. They are shown in separate columns and never added together.

Is this a full list of data center operators in the United States?

No. It shows the 20 named operators with the most sites tracked, out of 152 named operators recorded. Counts are sites Real Assets has recorded, not a census of the data center market in the United States. A site whose source names no operator is not attributed to anyone.

What do operating and planned mean?

Operating is a site that is open. Planned is a site that is not open yet: announced, planned or under construction. They are shown in separate columns and never added together.
