Stock market turmoil sheds stark light on the opaque AI economy

The global AI stock market experienced a turbulent week as investors reacted to breakthroughs in China's semiconductor industry. On Monday, Chinese memory chipmaker CXMT surged 466% on its Shanghai debut, reaching a valuation of 3.3 trillion yuan, while reports emerged that China had developed its own deep-ultraviolet lithography tools. These developments sent shockwaves through Western markets, with AI-linked chipmakers tumbling worldwide.
South Korea's Kospi index fell 11.5% on Tuesday and another 6% on Wednesday, dragged down by SK Hynix and Samsung Electronics. On Thursday, the Nasdaq briefly slipped into correction territory, dropping over 10% from its recent high before recovering. Nvidia lost more than 5% that day, ceding its position as the world's most valuable listed company to Apple. However, strong earnings from Amazon and Microsoft triggered a rebound on Friday, with the Kospi jumping nearly 20%, though the week still marked its worst month since 2008.
The market panic may be overblown, according to analysts. CXMT produces DRAM memory chips, which complement rather than compete with Nvidia's GPUs. The global DRAM shortage persists, and other memory makers like SK Hynix and Micron cannot meet demand. Forrester analyst Alvin Nguyen called the sell-off an 'overreaction,' noting the shortage could last until 2030.
A more serious concern is China's reported capability to manufacture lithography tools, a domain previously monopolized by ASML. If accurate, this could eventually allow China to produce GPUs rivaling Nvidia's. Yet experts caution that building competitive fabs takes years. 'Fabs still take years to develop,' Nguyen said.
Mark Boost, CEO of UK cloud firm Civo, echoed that sentiment, stating that 'investors are overreacting to the short-term threat.' He argued that manufacturing a few deep-ultraviolet machines is a symbolic victory, not a commercial replacement for ASML overnight. ASML's dominance remains structurally safe outside mainland China until Chinese tools match Western reliability.
Long term, these advances are gamechanging for the AI economy. Given US export controls, China's push for self-sufficiency was predictable. As IG's Chris Beauchamp noted, 'These Chinese developments are a wake-up call for Western investors.' While immediate disruption is limited, the trajectory points to a more competitive and fragmented global chip market.
