[COVER STORY] Black Friday: KOSPI sinks 6%, extending slide on US AI regulation fears
South Korea's KOSPI stock index dropped roughly 6% in a single session, continuing a broader slide attributed to investor concern over potential U.S. regulations targeting artificial intelligence. The selloff reflects how policy signals from Washington can ripple quickly through technology-heavy markets abroad.
Why this matters: U.S. AI policy decisions do not stay inside U.S. borders. When markets in South Korea drop 6% in a day over regulatory fears, it shows how much global capital is now tied to assumptions about how America will govern AI. Companies and investors everywhere are pricing in uncertainty they cannot control. That is worth watching, because the rules that eventually emerge will shape which AI systems get built, by whom, and under what constraints.
