Nvidia shares rose 4.4% to $235.74 after U.S. officials cleared about 10 Chinese firms, including Alibaba and Tencent, to buy its H200 AI chips, though no deliveries have occurred. CEO Jensen Huang is in Beijing as investors await Nvidia’s May 20 earnings report. Approved Chinese buyers can each purchase up to 75,000 chips under U.S. licensing terms. Lenovo confirmed its approval; Nvidia and other firms declined comment.
