South Korea’s KOSPI plunges 7.57% as AI doubts rattle investors

South Korea's KOSPI index fell 7.57% as investors grew skeptical about AI profitability, raising fears of a broader reevaluation of technology investments. The selloff is a macro risk-off signal that could spill into global equity and crypto markets, since digital assets have traded in sympathy with tech stocks during recent AI-driven rallies. Traders should watch whether this weakness deepens into a wider tech de-rating that pressures risk assets including BTC and ETH.
