Global chip stocks extended losses across Asia, following a sharp selloff in the U.S. The downturn is fueled by concerns over AI spending and China's technological progress. South Korea's Kospi index plunged 10%, triggering two trading halts, while Japan's Nikkei index fell 4%. U.S. chip stocks, including Micron, Super Micro, Intel, and Nvidia, also remained under pressure in premarket trading.
