  "account": "Last week saw a highly volatile period in the AI economy, particularly concerning western chipmakers. The situation began with Chinese memory chipmaker CXMT listing on the Shanghai stock market, with its value soaring by 466% to 3.3tn yuan (£365bn) on Monday. Simultaneously, China was reported to have developed its own tools for deep-ultraviolet lithography, a crucial technique in the computer chip supply chain previously dominated by Dutch company ASML.\n\nThe following day, shares of AI-linked companies, especially chipmakers, experienced significant drops worldwide, causing many indices to slide. South Korea's main share index, the Kospi, fell by 11.5% on Tuesday and an additional 6% on Wednesday. The NASDAQ, the main US tech index, plunged over 10% from its recent high on Thursday, only to recover somewhat the next day.\n\nNvidia, which had been overtaken by Apple as the world's largest listed company, saw a decline of more than 5% by Thursday evening. However, strong financial results from Amazon and Microsoft helped calm traders' nerves the following day. The Korean Kospi index recorded its worst month since the global financial crisis of October 2008, despite a nearly 20% jump on Thursday.\n\nThe advances in China's AI capabilities have left western investors jittery for several reasons. CXMT's debut is impressive, but it primarily produces dynamic random-access memory (DRAM) chips, which are essential for AI calculations. These chips are not graphics processing units (GPUs), which are the key components in AI systems.\n\nAnalyst Alvin Nguyen from Forrester suggested that the sell-off in SK Hynix and Micron shares was an overreaction since the global memory chip shortage is likely to persist until 2030. Furthermore, the ability of China to manufacture deep-ultraviolet lithography tools, which are used to etch ultra-fine lines on silicon wafers, could pose a more serious threat. However, this development is still years away, as creating semiconductor fabrication plants takes considerable time.\n\nDespite these advancements, many experts believe that the current correction in the market may be an overreaction. Mark Boost, CEO of the UK cloud company Civo, emphasized that investors are overreacting to the short-term threat posed by China's technological progress. He stated that manufacturing a few deep-ultraviolet machines is a symbolic victory, and not a commercial replacement for ASML's dominance overnight. ASML's global supremacy remains structurally safe outside mainland China, as fab operations depend on efficiency and yield, which the Chinese tools may not yet fully match.\n\nLong-term, the developments in China's AI capabilities are considered game-changing for the AI economy, though they should have been anticipated given US export controls. China has had no choice but to develop domestic capabilities in response to such restrictions. Experts predict that these Chinese chip companies may eventually undercut and outcompete the big chipmakers on price, leading to a shift in the global market.\n\nHowever, the concern remains that the AI economy is heavily dependent on a single company, Nvidia. Its shares have gradually recovered following the initial sell-off, but they remain below their previous levels. Analysts speculate that the \"central bank of AI\" could face challenges in the future, as its influence may eventually wane.",
  "summary": "Investors scramble to make sense of a shock Chinese challenge to the dominance of western chipmakers Even for the rollercoaster world of AI, last week was particularly volatile as investors scrambled to keep up with developments that threatened the dominance of the largest western chipmakers. It began with a double whammy. On Monday, the Chinese memory chipmaker CXMT floated on the Shanghai stock…",
