Nvidia stock’s next test: Trump’s AI chip tariff meets China’s H200 roadblock
President Trump signed a proclamation imposing a 25% tariff on select advanced AI chips, including Nvidia’s H200 and AMD’s MI325X. China barred Nvidia’s H200 from entering the country, disrupting suppliers and prompting order cancellations. Nvidia shares fell 0.48% Friday, while AMD and Microsoft rose ahead of the holiday-shortened week. The White House said most data center chips are excluded from the new tariffs.
