The Complete 2026 List of Data Centers in the USA by State
The United States runs more data centers than any other country on Earth, somewhere between 4,000 and 4,800 depending on how you count them.
That single fact explains why a clean list of data centers in the USA is so hard to find: the number keeps moving, and different databases draw the line in different places.
This guide gives you that list in a usable form.
You will see how many data centers the USA has in 2026, which states hold the most, the biggest markets by power capacity, the largest operators by facility count, and the single biggest campuses in the country.
Statista counted 4,423 US data centers as of April 2026, the most of any nation, ahead of the United Kingdom and Germany, but DataCenterMap has the total count at 4,703 and below is a list of data centers in the USA by State map-o-graphic format.
The rest of this article breaks that number down so you can see where the machines actually live.
How many data centers are in the USA?
A data center is a purpose-built facility that houses servers, storage, networking gear, and the power and cooling systems that keep them running around the clock.
The USA holds the largest concentration of these facilities anywhere in the world.
Counting them exactly is the hard part, because estimates run from about 3,700 operational sites to more than 5,400 once you include smaller enterprise server rooms.
Statista reported 4,423 US data centers in April 2026, while other trackers land near 4,000 depending on their cutoff date and definitions.
Roughly 40% of the world’s data centers sit inside US borders, according to figures compiled by Programs.com.
More than 1,500 new US sites are planned or under construction, based on Data Center Map figures analyzed by the Pew Research Center.
The count you land on depends on whether you mean operating facilities, total facilities including planned ones, or only commercial and hyperscale sites.
For a list, the useful move is to stop chasing one perfect number and look at where the facilities cluster instead.
List of Data Centers in the USA by State: data center markets in the USA
Data center markets are metro regions where facilities cluster because of cheap power, fiber connectivity, and available land.
Northern Virginia is the largest by a wide margin.
CBRE reported that Northern Virginia reached 4,039.6 megawatts of total inventory at the end of 2025, up 37% in a single year, with a vacancy rate of just 0.5%.
CBRE data shows that region alone holds nearly three and a half times more capacity than every secondary US market combined.
Atlanta ranked second at 1,459.2 megawatts, the fastest-growing major market, with 2,076 megawatts under construction, per CBRE.
Dallas-Fort Worth ranked third at 1,067.3 megawatts, the third US market to pass one gigawatt of supply, according to CBRE.
Chicago ranked fourth and now carries the nation’s highest data center rental rates.
Phoenix held 807.3 megawatts and Silicon Valley 489.2 megawatts, rounding out the established primary markets, CBRE reported.
Across all primary US markets, CBRE measured a record-low 1.4% vacancy rate in 2025 and an average asking rate of $195.94 per kilowatt per month.
| US data center market | Total inventory (MW), end of 2025 |
|---|---|
| Northern Virginia | 4,039.6 |
| Atlanta | 1,459.2 |
| Dallas-Fort Worth | 1,067.3 |
| Chicago | Top 4, highest US rents |
| Phoenix | 807.3 |
| Silicon Valley | 489.2 |
The largest data center operators in the USA
Data center operators fall into two camps: hyperscalers that run facilities for their own cloud, and colocation providers that rent space to other companies.
Digital Realty runs the most US facilities of any single operator, at 227 sites.
Lumen follows with 217 US facilities, and Amazon’s AWS operates 177, according to a tally compiled by C&C Technology Group.
Microsoft runs 103 US data centers and Equinix 101, placing the two giants nearly side by side.
Verizon operates 100 US facilities and Google 99, per the same C&C Technology Group count.
Equinix is the world’s largest colocation provider, running more than 260 data centers across 33 countries and 75 metros.
Digital Realty operates over 300 facilities worldwide through its PlatformDIGITAL business.
Synergy Research Group tracks the hyperscale layer, where AWS, Microsoft, and Google lead US capacity additions ahead of every colocation rival.
Altogether, C&C Technology Group counts 1,343 different operators and developers running US data centers.
| Operator | US facilities | Type |
|---|---|---|
| Digital Realty | 227 | Colocation |
| Lumen | 217 | Telecom, colocation |
| Amazon (AWS) | 177 | Hyperscaler |
| Microsoft | 103 | Hyperscaler |
| Equinix | 101 | Colocation |
| Verizon | 100 | Telecom |
| 99 | Hyperscaler |
The biggest individual data centers and campuses in the USA
A data center campus is a cluster of buildings on one site that operate as a single facility, and the US has the largest of them anywhere.
Switch’s Citadel Campus near Reno, Nevada is the largest data center campus in the country.
The Citadel sits on 2,000 acres and is planned to reach 7.2 million square feet with up to 650 megawatts of power, all of it renewable.
Its first building, Tahoe Reno 1, already covers about 1.3 million square feet and supports up to 130 megawatts on its own.
Meta’s Prineville, Oregon campus spans roughly 4.6 million square feet, making it one of the largest cloud campuses in the US.
Microsoft’s Stargate project in Abilene, Texas is built to reach 1.2 gigawatts of power when its first phase finishes, dwarfing older sites by capacity.
xAI’s Colossus 2 near Memphis, Tennessee is the largest operating AI data center in the country, drawing close to a gigawatt of power for GPU training.
Meta’s planned Hyperion campus in Louisiana aims for 5 gigawatts, which would make it the biggest AI campus ever built in the US.
| Campus or facility | Location | Scale |
|---|---|---|
| Switch Citadel Campus | Reno, Nevada | 7.2M sq ft planned, 650 MW |
| Meta Prineville | Prineville, Oregon | ~4.6M sq ft |
| Microsoft Stargate | Abilene, Texas | 1.2 GW (phase 1) |
| xAI Colossus 2 | Memphis, Tennessee | ~1 GW (operating) |
| Meta Hyperion (planned) | Louisiana | 5 GW planned |
Data centers in the USA by state
Five states hold most of the country’s data centers, and the ranking shifts depending on whether you count operating or total facilities.
Virginia and Texas sit at the top on almost every list.
The Pew Research Center, using Data Center Map figures, counted 398 operating data centers in Virginia and 296 in Texas as of early 2026.
California followed with 277, Ohio with 166, and New York with 148, per the same Pew analysis.
Broader counts that include smaller enterprise sites push the totals higher, with C&C Technology Group putting Texas at 566 facilities and Virginia at 502.
The South now leads new construction, with 754 planned data centers on top of 1,209 existing ones, the Pew Research Center found.
That shift is pulling activity into rural counties across the South and Midwest that had almost none five years ago.
| State | Operating data centers (early 2026) |
|---|---|
| Virginia | 398 |
| Texas | 296 |
| California | 277 |
| Ohio | 166 |
| New York | 148 |
Where the data center jobs are
The map of US data centers is also the map of US data center jobs, because every facility needs technicians, engineers, and operations staff on site.
Northern Virginia’s Loudoun County, nicknamed Data Center Alley, packs the densest hiring market in the country.
Texas, Georgia, Arizona, and Ohio are the fastest-rising job markets as construction moves toward cheaper power and land.
If you are choosing where to build a data center career, following the capacity is the simplest strategy, since the metros adding the most megawatts are the metros adding the most roles.
You can compare the top hiring metros in our guide to the best US cities for data center jobs, or start with the entry path in how to become a data center technician.

The USA holds somewhere between 4,000 and 5,400 data centers in 2026, more than any other country, and the number climbs every quarter.
Northern Virginia dominates by power capacity, Texas and Virginia lead by facility count, and Switch’s Citadel Campus stands as the single largest site.
Digital Realty, Lumen, Amazon, Microsoft, and Equinix operate the most facilities, while hyperscalers are building the biggest new campuses for AI.
