Cloud regions and AI campuses, October 2026
Summary
Two kinds of data center are growing at once, and they are built for different
reasons. Cloud regions are the established kind: Amazon, Microsoft and Google list
132 between them, in 76 metro areas across six areas of the world.
AI campuses are the new kind: single sites that draw hundreds of megawatts. Epoch AI
tracks 93, and the 72 that are already running draw 13.7 GW of IT
power, 86% of it in the United States.

Two kinds of data center
Cloud region
A group of data centers in one metro area, split into zones that fail
independently.
Rented by the hour. Customers pick a region for speed, or for the law: some data
must stay in its country.
Counted in regions and zones. The providers do not publish building counts.
AI campus
One site built around a single very large cluster of accelerator chips, to train
and run AI models.
Placed where a lot of power can be had quickly, not where the customers are.
Counted in megawatts of IT power. The figures are Epoch AI's estimates, from
permits, satellite images and company statements.
Cloud regions
Counts are as listed in each provider's documentation in October 2026. The three
lists overlap on purpose: the same metro areas, such as Northern Virginia, London,
Tokyo and Singapore, appear in all three. 35 of the 76 metro areas
have regions from more than one provider.

Azure lists the most regions, but 17 of its 57 have no
availability zones and 8 are open only by request, so it lists fewer
zones than Google, which has 41 regions and 124 zones. Asia Pacific
has the most regions of any area, 43, ahead of Europe with 38 and
North America with 31. Africa and South America have the fewest.
AI campuses
The largest running campus is Colossus 2, at 946 MW of IT power, ahead of Amazon New Carlisle
and Fairwater Atlanta. Most of the growth is still to come. If the plans hold, the 81
campuses on the map reach about 32 GW by 2029, more than twice what runs
today. Outside the United States, Johor in Malaysia is the biggest hub, with two
campuses and 895 MW, ahead of China with 731 MW. Planned power is Epoch
AI's estimate of the full build-out.

9 campuses show no running capacity yet. Most of them plan close to a
gigawatt or more by 2028: Meta's Hyperion in Louisiana, and the Stargate sites in
New Mexico, Texas, Michigan and Wisconsin and in Abu Dhabi.

What it means
Cloud regions follow people. They sit in metro areas with many customers, and the lists
now include recent regions in new countries: Mexico, Chile, Malaysia, New Zealand
and Thailand.
AI campuses follow power. They tend to sit in smaller places such as Abilene, New Albany
and Pryor, where land is cheaper and large grid connections are available. That
concentrates them: 86% of running power is in one country.
The map on the last page shows both. Cloud regions spread across the metro areas of the
world. AI campuses cluster, and most of them are in the United States.
Sources and method
Cloud regions: the AWS Regions table (docs.aws.amazon.com), the Azure regions list
(learn.microsoft.com) and the Google Cloud regions and zones table
(docs.cloud.google.com), read in October 2026. AWS's own tally is 39 regions and 124
availability zones, because it also counts regions that need a separate account,
such as GovCloud. We use the 34 in its account documentation.
AI campuses: Epoch AI, "AI data centers", epoch.ai/data/ai-data-centers, licensed
CC BY 4.0, retrieved in October 2026. Epoch tracks 93 campuses. 81 are on
the map: the 72 that run today and the 9 under construction. The
other 12 draw no power yet and are left off.
Epoch gives addresses, not coordinates. We placed each marker by hand, at town level
for campuses and metro level for cloud regions, so a marker can be off by a few
kilometers.
Prepared for internal use. Figures as of October 2026.
