10 Largest Data Center Markets in the World

Below is a closer look at the top 10 data center locations, based on installed power capacity.

These aren’t individual facilities – they’re large regional hubs where digital and robust data center infrastructure has grown rapidly to support cloud computing, AI training, and enterprise storage.

This data comes from the Energy and AI report published by the International Energy Agency (IEA).

1. Northern Virginia (USA): The Undisputed Data Center Capital

Northern Virginia leads every global ranking by a wide margin, thanks to its highly mature data center operations. This area (especially Loudoun and Prince William Counties) has become one of the top data center locations for digital infrastructure worldwide.

Locals often call it “Data Center Alley,” and with good reason – it now supports nearly 7 gigawatt (GW) of capacity, with more still in the pipeline.

Why it leads:

• It played a key role in early internet development, serving as one of the first connection points during the commercial rise of the web.
• Tax incentives helped it grow fast, especially after Virginia expanded exemptions on data center equipment. These policies will remain in place until at least 2035.
• There’s a deep talent pool in the region, with hundreds of universities and technical schools feeding into the workforce.

On top of that, energy companies have worked closely with local government to plan ahead. Long-term power agreements have supported solar growth, and the Coastal Virginia Offshore Wind project is partially driven by data center demand.

Still, growth on this scale brings tension. People living nearby have raised concerns about noise, the constant hum of cooling systems, and how these buildings affect property values.

2. Beijing (China): Strategic Capacity With Slower Growth

Beijing is the largest data center market in China, with over 2.3 GW of installed capacity. It powers national infrastructure, government systems, and enterprise cloud services, all of which depend on reliable data center management.

Core advantages:

• The digital infrastructure here is strong and well-established.
• It supports China’s push for data sovereignty, especially as the country strengthens its cloud services.

New development is limited, mainly due to strict energy rules in crowded urban areas. Authorities are careful about how much electricity these centers consume, and Beijing’s network is already under pressure.

3. Chicago (USA): Central Hub For Fibre & Cloud

Chicago remains one of the top data center markets in the US because it has a strong mix of available power, reliable fibre connections, access to skilled labor, and well-optimized data center operations.

Why it stands out:

• It sits in a great location for serving both coasts, which helps reduce latency and improve performance.
• The region already has the infrastructure in place, which makes building a data center easier and less expensive than in many coastal hubs.

Growth here is steady, though not dramatic. Chicago’s advantage lies in its balance – plenty of room to expand, without many of the bottlenecks seen in coastal hubs.

4. Singapore: Innovating Under Strict Limits

Singapore is one of the most advanced data center markets in Asia, especially when it comes to integrating the latest data center technology. It acts as a digital gateway for Southeast Asia, supporting tech ecosystems in Indonesia, Thailand, and Vietnam.

Growth constraints:

• The government paused new projects for a while, mainly due to energy and land shortages.
• Only highly efficient builds are now allowed, and each project must meet strict environmental targets.

Even with these limits, Singapore remains a critical market. Global cloud companies continue to invest here, knowing the country offers reliable infrastructure and strong regional connections.

5. Shanghai (China): Urban Density Meets Policy Friction

Shanghai is another major entry in the list of global data center locations, especially for enterprise clients. It supports a wide range of industries and financial services.

What helps it grow:

• There’s strong demand from large businesses, and the city’s fibre network is already robust – a necessary match for advanced data center servers.
• Its location makes it a natural tech hub for eastern China.

However, growth is slowing down; tight planning controls and energy use restrictions are now making it more challenging to expand.

6. Pearl River Delta (China): Mega-Region Powering Cross-Border Flow

This region combines the power of Guangzhou, Shenzhen, and Hong Kong, creating one of the most connected and diverse data center markets globally.

Why it matters:

• It links mainland China to global business hubs, supporting both domestic and international platforms.
• There is a wide range of industries, from finance to manufacturing, all of which require strong digital infrastructure.

The region benefits from high-speed links and a dense data center network across multiple cities. It’s ideal for companies needing regional backup and low-latency cross-border access.

7. Dallas (USA): Expanding Fast With Tax Support

Dallas has become one of the top choices for data center growth in the US, particularly for companies seeking to avoid congestion in areas like California or Virginia.

Why developers are choosing Dallas:

• Electricity is affordable and widely available.
• There’s plenty of land for large campuses.
• Texas offers helpful tax incentives and flexible planning rules, encouraging the adoption of modern data center technology.

Many hyperscale companies now see Dallas as a long-term base. It’s central, cost-effective, and easier to scale compared to older, busier markets.

8. Dublin (Ireland): Tech Hub Facing Infrastructure Strain

Dublin has attracted major US tech firms for years, thanks to Ireland’s corporate tax policies and EU access. It’s home to major cloud data centers operated by some of the largest data center providers, including Google, Meta, and Amazon.

Why it became a hotspot:

• English-speaking talent and business-friendly laws made it the perfect entry point for global tech.
• It also has direct connections to North America and Europe via subsea cables.

But growth is slowing down. The Irish government has paused new approvals in some areas due to grid concerns, so developers now need to show that their projects won’t overload local energy networks.

9. Omaha (USA): Stable, Quiet Growth in the Midwest

Omaha isn’t the flashiest name on the list, but it’s quietly building momentum through steady investments in data center infrastructure.

With lower land costs and fewer barriers to development, it’s become a good fit for companies that want a more predictable setup to host and maintain their data center servers.

Why it works:

• Electricity and land are more affordable than in bigger cities.
• There’s less local pushback, making planning and construction easier.
• Many companies like the low profile and quiet stability the region offers.

It’s not making headlines, but Omaha is earning trust among developers who value long-term planning and simple logistics.

10. London (UK): Legacy Market Adapting to Limits

London has played a major role in the global data center market for years. As a leading financial hub with strong demand for cloud services, it was one of the first places in Europe to attract large-scale builds.

Why it plays a key role:

• It supports essential sectors like banking, insurance, and legal services.
• Many of the world’s biggest cloud providers already operate facilities here, making London a core hub for major data center providers.
• The city is well connected through subsea fibre routes that link it to North America and mainland Europe.

Still, growth has started to slow. Rising electricity costs have made new projects more expensive, and stricter planning rules are making approvals harder to secure.

Land in and around the city is limited, and anyone building a data center often faces long timelines to get started.

The Next Wave: New Data Center Sites to Watch

Some new data center markets are starting to gain momentum in the US, even though most of the development is still going into the country’s biggest hubs.

Las Vegas, Nevada, and El Paso, Texas, are two names showing up more often in project announcements related to data center construction.

At the moment, both cities have less than 500 megawatts of installed capacity, but several large campuses have been announced, and developers are paying attention to the scale of upcoming data center construction.

These markets offer room to grow without the same pressure on grid infrastructure seen in places like Northern Virginia or Dublin.

Still, the majority of new capacity in the US – around 50% – is going to markets that already have over 1 gigawatt installed. So while places like Las Vegas and El Paso are on the rise, they’re adding to the landscape, not replacing the major hubs.

The Bottom Line

This guide doesn’t focus on a single facility as the largest data center in the world – instead, it highlights the top global markets based on total installed capacity. These hubs are powering the digital economy, shaping how we store, process, and move data at scale.

As new markets emerge and existing ones adapt, the global data center market will keep shifting, driven by energy, policy, and demand for cloud services.
