Asian shares mixed as Nvidia probe hits AI stocks despite Wall Street rally

Asian shares were mostly lower Thursday as concerns over Nvidia CEO Jensen Huang's personal conduct weighed on AI-related stocks, despite a Wall Street rally the previous day. Nvidia shares fell 8.6% in after-hours trading following reports of a board meeting about his affair with a Chinese woman. Japan's Nikkei edged 0.1% lower, while Taiwan's Taiex lost 1.2% and Hong Kong's Hang Seng declined 0.9%. The declines came as Nvidia investigates Huang's relationship with a businesswoman allegedly linked to intelligence and chip transfers to China. On Wednesday, the S&P 500 rose 1.3% and the Nasdaq gained 1.6%. Broader investor concerns persist about AI industry profitability and whether massive investments will pay off. CoreWeave, an AI chip cloud provider, jumped 24.7% after reporting better-than-expected losses. U.S. crude fell to $85.48 a barrel, while the dollar slipped to 159.74 yen.
