Asian AI stocks rise as CoreWeave's strong results lift regional tech shares

Asian AI-related stocks rose Wednesday after AI cloud provider CoreWeave reported better-than-expected quarterly results, boosting confidence in infrastructure demand and lifting semiconductor shares in South Korea, Japan, and Taiwan, though Chinese and Hong Kong tech stocks lagged on US inflation concerns. CoreWeave shares jumped nearly 13% in after-hours trading after the company beat third-quarter revenue expectations and raised its full-year outlook, reporting revenue of $3.66 billion, up 168% year-over-year and above analyst estimates of about $3.55 billion. The company lifted its 2026 revenue forecast to $13 billion-$13.3 billion from a prior range of $12 billion-$13 billion. South Korea's KOSPI rose 1.8% with SK Hynix gaining 3.6%, while Japan's Nikkei 225 climbed 1.2% and Taiwan Semiconductor Manufacturing added 2.6%. The gains were uneven, however, as China's CSI 300 fell 0.2% and Hong Kong's Hang Seng dropped 0.9%, pressured by higher US inflation data that raised expectations of further Federal Reserve tightening.
