Global AI Stock Rout Hits South Korea, KOSPI Plunges 8%

Global stock markets plunged on Friday as AI investment sentiment collapsed, with South Korea's KOSPI falling over 8% at the open, triggering a circuit breaker, and US major indices dropping sharply the previous day. The selloff was driven by concerns over delayed AI data center construction following the US Democratic Party's midterm election victory, with Senator Bernie Sanders calling for a nationwide moratorium and investors dumping semiconductor stocks on fears of reduced memory demand. Microsoft and Meta signaled caution on new data center projects, while credit default swap premiums for CoreWeave and SpaceX hit record highs. Nvidia fell 9.26%, Micron dropped 17.46%, and the Magnificent Seven lost over $1 trillion in market value.
