South Korea stocks plunge as US midterm results spark AI selloff

Semiconductor shares led the sell-off as investors worried a Democratic-led Congress could slow data-center growth and weaken demand for AI chips.

  • On Friday, the South Korean benchmark KOSPI plunged more than 8% in early trading, triggering a 20-minute circuit breaker as it fell below the 5,000 mark for the first time in months.
  • Investors dumped chipmakers following a sharp overnight sell-off on Wall Street, where concerns grew that Democrats' midterm election victories could lead to stricter regulations on data-center development, potentially curbing demand for AI chips.
  • Shares of major chipmakers suffered sharply, with SK hynix tumbling about 11.7% and Samsung Electronics falling about 10% in early trading, as selling pressure spread to other large stocks including Hyundai Motor, down 6.8%.
  • Finance Minister Lee Hyoung-il pledged Friday that financial authorities will formulate measures to stabilize market volatility, with speculation about potential interventions including a short-selling ban or stock market stabilization fund.
  • Despite the turmoil, President Lee Jae Myung committed in his budget speech on Nov. 2 to doubling spending on AI and semiconductors to a record $16 billion in 2027, underscoring South Korea's heavy economic reliance on the sector.
