China Overtakes US as World Number One in Supercomputing, Trump Responds

The technological battle between the United States (US) and China continues, with the world’s two largest economies racing to deliver the latest and most sophisticated innovations to dominate the world. However, the US appears to have conceded defeat to China in the supercomputer sector. According to Reuters on Wednesday (24/6/2026), China has just knocked the US out of the top spot for the world’s fastest supercomputer. Experts say this result does not necessarily mean China holds a superior position in the race to dominate artificial intelligence (AI) technology. The supercomputing lead merely demonstrates China’s significant ambition to achieve self-sufficiency in computing systems, without relying on foreign technology. The LineShine system at the National Supercomputing Centre in Shenzhen, China, uses domestically designed chips and won the top spot in the ‘TOP500’, a global supercomputer ranking published every two years. The ranking was announced as the US and China intensify competition in the advanced computing sector. Earlier this week, US President Donald Trump signed an executive order to secure America’s position ahead of China in the emerging field of quantum computing. In the June 2026 edition of the TOP500 list, LineShine defeated El Capitan, a US supercomputer located at the Lawrence Livermore National Laboratory, which the US government uses to develop and maintain its nuclear weapons stockpile. However, technology and policy experts interviewed by Reuters said China’s victory over the US in supercomputing does not mean China possesses the most advanced computers for AI work. This is because the industry has changed in recent years and the methods used to compile the list are dynamic. LineShine also ranked fourth in a benchmark test designed to simulate computing jobs more akin to AI. For decades, supercomputers combined many separate machines to tackle complex scientific problems, such as simulating how atoms interact with one another, and were largely the domain of national laboratories and universities. To make the TOP500 list, operators must run a series of benchmark tests aimed at replicating that work. In recent years, however, cloud computing companies like Microsoft, Amazon, and Alphabet’s Google have built their own massive supercomputers but directed them towards AI workloads. Most of these firms choose not to compete for a spot on the TOP500 list. A study last year by AI policy researchers Konstantin Pilz, James Sanders, Robi Rahman, and Lennart Heim found that SpaceX’s Colossus system is likely already more advanced than the US government’s El Capitan. ‘If the large-scale cloud service providers submitted their systems, this ’world’s fastest system’ wouldn’t make the top five,’ said Jimmy Goodrich, a senior researcher at the University of California’s Institute on Global Conflict and Cooperation.
