How Many Data Centers Does China Have? The 2026 Numbers
Key Numbers
Key Takeaways
- 1China has 376 data centers on Data Center Map but nearly 11 million server racks in service. The US lists 4,767 data centers, about 13 times more, yet China added about 7.8 million racks since 2019 against 8.8 million in the US.
- 2Dividing China's racks by its listed sites gives roughly 29,000 racks per site, which no real building holds. Counts of buildings understate China's capacity, and the government's own figure is 633 hyperscale and large data centres.
- 3China's AI data centers face two limits: restricted access to Nvidia chips, and underuse, with reports of up to 80% of new capacity idle and some western sites at 20% to 30% utilization.
China has 376 data centers on the largest public directory, but nearly 11 million server racks in service. Both are correct. They count different things, which is why every answer to "how many data centers does China have" seems to contradict the last one.
The same directory lists 4,767 data centers in the United States, about 13 times China's count (Data Center Map, August 2026). Yet China's rack count tripled from 3.15 million in 2019 to nearly 11 million in 2025, almost matching the 8.8 million racks the US added over the same period (Oxford Institute for Energy Studies, February 2026). So the building count says little about how much computing a country actually has.
By the end you will know why the count swings between 376 and 633, how China stacks up against the US, who runs the facilities, and why so many of China's new AI halls are short on chips or short on customers.

How Many Data Centers Does China Have?
It depends on what you count. Data Center Map lists 376 data centers in China from 85 operators (August 2026). Chinese policy reporting uses a different yardstick: 633 hyperscale and large data centres had been built and put into operation under the East Data, West Computing program by 2024, according to ASPI's The Strategist (May 2026). Neither is a census of every building.
| Source | What it counts | Figure | Date |
|---|---|---|---|
| Data Center Map | Listed colocation and cloud facilities | 376 data centers, 85 operators | August 2026 |
| ASPI, The Strategist | Hyperscale and large data centres under East Data, West Computing | 633 operational | By 2024 |
| China Ministry of Industry and Information Technology (MIIT) | Standard server racks in use | 10.43 million | Q1 2025 |
| Oxford Institute for Energy Studies (OIES) | Standard server racks, citing official statistics | Nearly 11 million | 2025 |
Racks are the better measure of capacity. MIIT reported 10.43 million standard racks in use in the first quarter of 2025, an 18.5% rise from 2024 (People's Posts and Telecommunications News, August 2025). The Oxford Institute for Energy Studies puts the 2025 total at nearly 11 million, up from 3.15 million in 2019.
So why do directories and government figures differ so much? A directory only counts sites that operators choose to list. OIES notes that data centres in China are "virtually all owned and operated by Chinese companies", from state firms like China Unicom to private giants like Alibaba and Tencent, and a good share of enterprise and carrier sites never make it into a global directory. If you need one number to quote, we would use racks, because they come from government statistics, and say "nearly 11 million racks" rather than offering a building count.
China vs the US: How Many Data Centers Are in the US?
The US has far more listed data centers than China. The gap shrinks fast once you measure racks, power, or hyperscale capacity instead. Data Center Map lists 4,767 US data centers (August 2026), roughly 13 times China's 376. Another dataset, Cloudscene, counts 5,427 US facilities, about 46% of all data centers worldwide. So the number of data centers in the US sits somewhere between 4,700 and 5,400, depending on whose database you trust.
| Measure | China | United States | Source |
|---|---|---|---|
| Listed data centers | 376 | 4,767 | Data Center Map, Aug 2026 |
| Racks added since 2019 | About 7.8 million (3.15M to nearly 11M) | 8.8 million | OIES, Feb 2026 |
| Hyperscale capacity share | About a third of the non-US balance | 54% of worldwide capacity | Synergy Research, end 2024 |
| Data center electricity growth to 2030 | +175 TWh (+170%) | +240 TWh (+130%) | IEA, 2025 |
Synergy Research Group counted 1,136 hyperscale data centers worldwide at the end of 2024. The US held 54% of total capacity, with Europe and China each accounting for about a third of the rest. If that tier is new to you, our explainer on hyperscale data centers covers the definition.
The International Energy Agency expects data center electricity use to double from about 415 TWh in 2024 to around 945 TWh by 2030, and says China and the US together will account for nearly 80% of that growth.

Where China's Data Centers Are: East Data, West Computing
Most of China's data center capacity still sits near Shanghai and Guangzhou, even after five years of government effort to move it west. The East Data, West Computing project, launched in 2021, steers new capacity toward eight national hub nodes: Beijing-Tianjin-Hebei, the Yangtze River Delta, the Guangdong-Hong Kong-Macao Greater Bay Area, Chengdu-Chongqing, Guizhou, Inner Mongolia, Gansu, and Ningxia (OIES, 2026).
Western provinces have cheap land and spare electricity, and eastern cities have the users, so the plan is to store data in the west and do the computing in the east.
In practice the program has done less than advertised. A 2025 evaluation cited by OIES found it cut energy use by only 4% to 12%, mostly through lower cooling loads in colder climates. That saving is real, but small. Latency-sensitive work cannot travel far from users, and 75% of China's digital industry income still comes from East China. Coastal provinces now restrict new data center approvals, while grid connections in Ningxia and Gansu can be quick.
Western sites have a second problem. The Strategist reports that some of them run at only 20% to 30% utilization, which we cover below.
Who Builds and Runs China's Data Centers
Three groups run almost all of China's data centers: state telecom carriers, internet giants, and independent colocation firms. Foreign operators barely feature, partly because, as OIES explains, Chinese leaders see data center capacity as a national security issue as well as an economic one.
| Operator type | Examples | Role |
|---|---|---|
| State telecom carriers | China Mobile, China Telecom, China Unicom | Large facility fleets and the national network |
| Internet and cloud giants | Alibaba Cloud, Tencent, Huawei Cloud, ByteDance, Baidu | Own AI and cloud capacity |
| Independent colocation | GDS, VNET, Chindata | Lease space to cloud and enterprise tenants |
Alibaba gives the clearest spending signal. It pledged 380 billion yuan, about $53 billion, over three years for cloud and AI infrastructure in February 2025.
"We are vigorously advancing a three-year, 380 billion [yuan] AI infrastructure initiative." (Eddie Wu, Alibaba CEO, September 2025)
Wu said Alibaba would keep raising that investment. By 2026 the South China Morning Post reported the company was roughly halfway through the plan.
China Data Center Power, Efficiency, and Cost
China's data centers use between 1.7% and 2.7% of the country's electricity, depending on who is counting and what they include. ASPI puts the share at 1.68%, with a rise to 3% by 2030. OIES cites 200 TWh in 2023, which it estimates at 2.7% of Chinese electricity demand. The IEA projects China's data center electricity use will grow by about 175 TWh, or 170%, by 2030.
| Item | Figure | Source |
|---|---|---|
| Average PUE across the sector, 2023 | About 1.5 | OIES |
| PUE target for new large data centres (2024) | 1.25 | OIES |
| Renewable share required for new data centres (2025) | 80% | OIES |
| Electricity subsidy for sites using domestic chips (from Nov 2025) | Up to 50% | ASPI |
| Chinese spot power price, 2023-2024 | RMB 300-400/MWh ($43-58) | OIES |
| US regional spot power price, 2024 | $40-50/MWh | OIES, citing EIA |
The Number Most Guides Don't Show
Divide China's nearly 11 million racks by the 376 data centers on Data Center Map and you get roughly 29,000 racks per listed site. No real building holds that many, so the directory has to be showing only a slice of the country. That is also why the 633 hyperscale and large data centres in the government-side count is a better guide to how many big facilities exist.
The power table also tests a popular claim. As OIES reports, Nvidia CEO Jensen Huang predicted in November 2025 that China would beat the US on AI, partly on cheap electricity. OIES found that Chinese industrial power prices are comparable to US prices and below Europe's. China has plenty of power, but it does not have free power.
China AI Chips and the Idle Data Center Problem
China's AI data centers are held back less by buildings or electricity than by two other things: access to the best chips, and a lot of new capacity that nobody is using.
Start with chips, where Nvidia's own filing is blunt. Its fiscal 2026 annual report gives the timeline:
- April 2025: the US begins requiring an export license for the H20 chip
- August 2025: licenses granted for certain H20 sales to certain China-based customers
- February 2026: a license for small H200 shipments, with no H200 revenue so far
"NVIDIA was effectively foreclosed from competing in China's data center computing/compute market." (NVIDIA Form 10-K, fiscal 2026)
Beijing is pushing in the same direction. Nvidia says Chinese authorities encouraged customers to buy from its China-based competitors, and from November 2025 China offers electricity subsidies of up to 50% for data centers that use domestically made chips (ASPI, May 2026). Our read: Beijing would rather see slower domestic chips running than halls sitting dark.
Then there is the empty space. More than 500 new data center projects were announced in 2023 and 2024, and at least 150 were finished and running by the end of 2024, according to MIT Technology Review (March 2025). Local outlets reported that up to 80% of newly built computing resources were unused, though that is an estimate from press reports, not a government figure. Rental prices for an eight-GPU Nvidia H100 server fell from about 180,000 yuan a month to 75,000 yuan, a drop of about 58% by our math.
"DeepSeek is a moment of reckoning for the Chinese AI industry." (Hancheng Cao, Emory University, quoted by MIT Technology Review, March 2025)
Reasoning models moved demand from training toward inference, which hurts sites built far from users for pretraining. Beijing now requires data centers to reach at least 60% utilization and bars new large data centers in cities where existing ones run below 50%. President Xi Jinping questioned the rush himself: "Do all provinces in the country have to develop industries in these directions?" (as reported by ASPI, May 2026).
What China's Data Centers Mean for AI
The racks are not China's problem. When you ask a chatbot a question, the request lands on one of them somewhere, and China has plenty. What it lacks for now is enough top-end accelerators, plus enough demand to fill the western halls, and inference will decide how fast that second gap closes.
Three things worth watching over the next two years:
- Whether H200 licenses turn into real shipments, or Beijing keeps steering buyers to domestic chips
- Whether utilization in western hubs climbs toward the 60% floor Beijing set
- Whether Alibaba, Tencent, and ByteDance keep raising AI capex while rental prices stay low
The count matters less than the use. Whether China has 376 data centers or 633, it is only ahead if the racks inside them are doing useful work, and that is the open question.
For the US side of the comparison, our breakdown of what AI data centers are and how they differ from standard facilities is the place to start. AI training vs inference explained shows why the shift to inference matters, and how much energy AI uses covers the electricity side.
Frequently Asked Questions
How many data centers does China have?
China has 376 data centers on Data Center Map as of August 2026, from 85 operators. Official policy reporting counts 633 hyperscale and large data centres built under East Data, West Computing by 2024. By rack count, China had 10.43 million standard racks in use in Q1 2025 (MIIT) and nearly 11 million in 2025 (OIES). No single official facility census exists, so the answer depends on the unit.
How many data centers are in the United States compared with China?
Data Center Map lists 4,767 US data centers and 376 in China (August 2026), a ratio of about 13 to 1. Cloudscene counts 5,427 US facilities. On racks the gap closes: China added about 7.8 million racks from 2019 to 2025, against 8.8 million in the US (OIES, 2026).
Which country has the most data centers?
The United States has the most, with 4,767 listed on Data Center Map (August 2026) and about 46% of all data centers worldwide in the Cloudscene dataset. The US also holds 54% of total hyperscale capacity (Synergy Research, end 2024).
Can China get enough AI chips for its data centers?
Not the best ones. The US required licenses for Nvidia H20 exports in April 2025 and licensed only small H200 shipments in February 2026, and Nvidia says it was effectively foreclosed from China's data center market (Form 10-K, fiscal 2026). China is pushing domestic chips with electricity subsidies of up to 50% for sites that use them (ASPI, May 2026).
Are China's AI data centers sitting empty?
Many are underused. MIT Technology Review reported in March 2025 that local outlets estimated up to 80% of newly built computing resources were unused, and ASPI says some western data centres run at 20% to 30% utilization (May 2026). Beijing now requires at least 60% utilization and bars new large sites in cities where existing ones run below 50%.
How much electricity do China's data centers use?
Estimates range from 1.68% of China's electricity (ASPI) to 2.7%, or 200 TWh in 2023 (OIES). The IEA projects China's data center electricity use will rise by about 175 TWh, or 170%, by 2030. Globally, the IEA expects data center demand to grow from 415 TWh in 2024 to 945 TWh in 2030.
