South Korea's AI rally craters on tech doubts
The world's hottest stock market just hit its worst day of the year. South Korea's Kospi dropped 5.3 percent as Samsung and SK Hynix each fell more than 7 percent, unwinding months of AI-driven gains that had made Korea the global leader in 2026. The trigger was Nvidia CEO Jensen Huang walking back claims of a $100 billion OpenAI investment and Broadcom's weaker AI outlook spoiling the party. Korea's concentration in just two chip giants made it the canary in the coal mine for global AI sentiment. The won hit its weakest level since 2009, and margin loans are near 20-year highs, suggesting this rout has further to run.
