Global stock markets dropped sharply today as a U.S. tech sell-off triggered concerns that AI-driven valuations may be overextended. Asia led the declines with South Korea’s Kospi down about 6.2% and Japan’s Nikkei falling 4.3%. AI-hardware names such as Samsung Electronics and SK Hynix lost over 6%. Investors cited warnings from Wall Street that equity markets may be closer to a correction than a rally. While Bitcoin rose slightly, safe-haven flows pushed yields lower and the U.S. dollar weakened.
