Chinese AI shares tumble after Nvidia’s Jensen Huang resigns

Chinese AI and technology shares fell on Friday as investors worried that Jensen Huang’s departure as Nvidia chief executive could lead to tighter US restrictions on China’s access to advanced chips. The prospect matters because Chinese AI developers rely on computing capacity, while some hardware suppliers depend heavily on sales to US customers.

AI model firms Z.AI and MiniMax, and data centre suppliers Zhongji Innolight and Eoptolink, were among those hit. Chinese chipmakers gained: Cambricon rose 1.2 per cent and was set for a 22 per cent weekly rise, while Hygon was poised to gain 7 per cent. US lawmakers have voiced support for tighter chip export limits, and Washington is considering barring imports of new Chinese optical transceivers.
