How many data centers are there?

How many data centers are in the United States?

Note: data-center counts come from commercial trackers and vary by methodology, so figures differ between sources.

• The United States had about 5,427 data centers as of May 2026, the most of any country.
• That is roughly 46% of the global total, a commanding lead.
• Counts vary by source, with another dataset listing the US closer to 4,184.
• The variation exists because no official registry counts every facility the same way.
• In Synergy’s Q3 2025 release, the US accounted for about 55% of global hyperscale capacity, measured by MW of critical IT load.

Whichever count you use, the conclusion holds. The United States hosts close to half the world’s listed data centers and, in Synergy’s latest country-share release, accounted for just over half of global hyperscale capacity. That dominance is now being deepened by the race to build AI infrastructure.

How many data centers are there worldwide?

Note: the worldwide figure is a tracker estimate, since definitions of a data center differ across sources.

• There were more than 11,700 operational data centers worldwide as of May 2026.
• They range from massive hyperscale campuses to small edge and colocation facilities.
• The footprint is highly concentrated, with the US alone holding about 46%.
• The top five countries together account for the majority of all facilities.
• The count keeps rising as AI and cloud demand drive new construction.

The raw count understates the real story, since it treats a small edge node and a billion-dollar hyperscale campus as one each. Capacity, measured in power and compute, is even more concentrated than the facility count suggests.

How many data centers do Google and Amazon have?

• Hyperscalers report regions and zones rather than a simple public count of buildings.
• AWS spans 39 regions and 123 availability zones, and says each Availability Zone consists of one or more discrete data centers.
• Google Cloud operates 43 regions and 130 zones worldwide.
• Google separately lists 30 active data center locations across 11 active countries.
• Exact building counts and the owned-versus-leased mix are not fully public, so regions, zones and published locations are the safest comparison points.

Exact building counts stay private, which is why regions, zones and published data-center locations are the safest way to size these giants. A single region can contain multiple zones, and each AWS Availability Zone consists of one or more discrete data centers.

Which countries have the most data centers?

• The United States leads by a huge margin with about 5,427 data centers.
• Germany ranks second with roughly 529, followed by the United Kingdom at 523.
• China holds about 449 and Canada around 337.
• The US lead is roughly ten times the size of the next-largest country.
• These rankings count facilities, not capacity, which is even more US-weighted.

The gap between first and second place is the headline. The United States hosts more data centers than the rest of the top ten combined, a concentration that shapes global latency, energy use and digital power.

How many hyperscale data centers are there?

Note: hyperscale counts come from Synergy Research, which filters out smaller points of presence and marketing claims.

• There were 1,360 hyperscale data centers worldwide at the end of 2025, up from 1,136 a year earlier.
• The count passed 1,000 for the first time in early 2024, up from 992 at the end of 2023.
• Operators added 130 to 140 a year historically, a pace that accelerated sharply in 2025 as AI buildout ramped up.
• Hyperscale sites made up about 48% of total capacity, forecast to reach 67% by 2031.
• A pipeline of nearly 800 future facilities is planned or under construction.

Hyperscale is where capacity is shifting fastest. These campuses are not just multiplying, they are getting larger, with AI workloads supercharging the average size of each new facility that comes online.

How big is the data center market?

Note: market-size figures vary by how each analyst defines the data center market, so treat these as estimates.

• Statista-linked market summaries place the global data center market near $527 billion in 2025.
• Statista’s public market forecast lists 2026 revenue at about $573 billion and projects revenue near $739 billion by 2030.
• That supports a compound annual growth rate of about 6.6% for the 2026 to 2030 forecast period.
• AI demand is driving hyperscale capacity to double in about three years.
• In Statista’s forecast, network infrastructure is the largest segment, projected near $270 billion in 2026.

The market is large and compounding, but the bigger signal is hyperscale capacity doubling in about three years. That pace, driven by AI, explains the construction boom reshaping power grids and local economies worldwide. For the cloud side, see our cloud market share research.
