Asian stock markets experienced a significant downturn, led by technology shares, on Tuesday. The decline was driven by concerns over increased competition from China's semiconductor sector and the substantial financial commitments required for the artificial intelligence boom. South Korea's KOSPI index plunged over 8%, triggering a circuit breaker, while Japan's Nikkei slid 4.5%. This followed an overnight sell-off on Wall Street, with Nvidia shares dropping 5% due to reports of financing talks for an OpenAI data centre project.
Adding to the competitive fears, China has begun manufacturing its own immersion deep ultraviolet lithography machines, a technology previously dominated by Dutch supplier ASML, which saw its shares fall 8.5%. The surge in Chinese semiconductor firm CXMT Corp's shares on its Shanghai debut also highlighted growing investor confidence in China's AI ecosystem.
