Key Takeaways
- The U.S. has 171 supercomputers, four times more than the next country, Japan, which has 43.
- China is tied for third alongside Germany, both with 40 supercomputers.
Supercomputers are used for everything from weather forecasting and high-powered simulations to artificial intelligence and defense.
The number of supercomputers a country has gives an indication of their technological and economic positioning, and how they prioritize frontier research.
This graphic ranks the countries with the most supercomputers, and the data comes from TOP500’s November 2025 list.
Which Countries Have the Most Supercomputers?
The U.S., the birthplace of supercomputers, dominates the list at 171. The figure is four times higher the number of supercomputers Japan has, which comes in second place at 43.
The data table below shows the number of supercomputers per country as of November 2025:
| Country | Supercomputers |

China and Germany trail closely, tied in third and fourth place at 40 supercomputers.
The ranking is significantly top-heavy, as the top three countries have more supercomputers than all the other 43 countries combined. In total, 26 countries have five or fewer supercomputers each, while 11 have just one supercomputer.
It is not necessarily smaller countries that have fewer supercomputers. Singapore, for example, has the same number as Russia and India at five. The Singaporean government recently launched a supercomputing hub as it looks to become Southeast Asia’s AI leader.
Increasing AI-Driven Supercomputer Demand
Demand for supercomputers is increasing alongside AI, which requires massive computational power to be trained and run, which far surpass what regular computers are capable of.
There are different types of supercomputers but generally they can crunch vast and complex datasets at speed, far surpassing humanity’s capabilities. By outputting useful information, supercomputers are used to make decisions across health, climate, and material science, which is why they are tipped to hold the key to some of society’s greatest challenges.
Nordic countries actually share access to their supercomputers in efforts to “enable excellence” and contribute towards the UN’s sustainable Development Goals.
The Finland-based LUMI supercomputer, the ninth most powerful in the world, was set up specifically with this in mind; it is hosted by a consortium of 10 countries, including the Nordics and their neighbor Estonia, to share resources and increase researcher access to some of the world’s most powerful computers.
The EU-funded RAISE center was set to develop novel AI technologies that can run effectively on supercomputers, while the U.S. is ramping up partnerships with AI companies to stack its national labs with powerful compute clusters.
