  • Rep. Mast accuses Nvidia, Jensen Huang of selling AI chips to Chinese military-linked firms
    January 18, 2026, 2:28 AM EST. U.S. Rep. Brian Mast (R-Fla.) on Saturday accused Nvidia Corp. and CEO Jensen Huang of helping the Chinese military by selling advanced AI chips to firms linked to Beijing, including Alibaba and Tencent. In posts on X, Mast said he is trying to stop that from happening and challenged Huang to a debate, while criticizing Nvidia's policies on transgender facilities and financial support for Rep. Ilhan Omar. He urged followers to state their positions on the issue. Nvidia's China business has faced headwinds such as a global memory-chip shortage and export-control considerations on H200 AI processors. Beijing has reportedly restricted purchase volumes. Despite regulatory pressure, analysts still view Nvidia as a leading growth stock in semiconductors, driven by AI monetization.
