Global markets tumbled as investors pulled back from the artificial-intelligence trade that has powered stocks for much of the past year. Asian shares led the slide, with Tokyo falling nearly 5% — and by some accounts more than 5% — as slumping AI-linked stocks dragged world markets lower.
The selloff rippled across the region. China's AI shares tumbled as a Wall Street rout deepened, according to Investing.com, while Bloomberg reported that Japanese stocks dived on worries about how much longer the AI rally can run. Reuters noted how Korean stocks have shifted from a trusted market bellwether into a vehicle for AI enthusiasm.
At the center sat chip giant TSMC. Crypto Briefing reported that the company's record-breaking quarter nonetheless triggered a 7.3% plunge in its stock and set off a broader selloff in Asian chipmakers. Part of the unease traces to caution about the future: Morningstar senior equity analyst Phelix Lee told CNBC that TSMC's reluctance to give long-term revenue growth guidance reflects a wariness at Asia's most valuable company. Separately, Wccftech reported that TSMC's CEO stressed that choosing chipmaking technology "isn't like buying milk from 7-Eleven" and admitted he was jealous of rival Samsung's profits.
The deeper worry is valuation. The Financial Times framed the moment as the AI trade "going into reverse." Analysis cited by MSN said the AI chip rally is losing momentum as investors reassess sky-high valuations and rotate money toward hyperscalers, with those cloud giants' capital-expenditure growth projected to slow sharply after this year.
Why it matters: AI-linked chipmakers have become the engine of global stock gains, so a sudden reassessment of their worth can drag down retirement accounts and markets far beyond the technology sector.
