AI Regulation Fears Trigger Chip Market Sell-Off in South Korea
What happened
On November 5, 2026, South Korea's Kospi index plunged more than 8%, triggering a trading circuit breaker. The market drop followed sharp declines in U.S. stocks, including the S&P 500, as investors reassessed the potential impact of Democratic midterm election victories on AI regulation and data center construction. Samsung Electronics and SK Hynix, major memory chip makers, experienced sharp stock declines.
