A U.S. government agency is conducting a broad review of how Chinese AI companies have obtained access to Nvidia's most advanced chips despite years of export controls, with scrutiny focused on overseas data centers that let Chinese firms rent computing power remotely. Bloomberg reported the review follows recent Chinese AI advances that showed effective use of restricted Nvidia processors. The Commerce Department's Bureau of Industry and Security moved on May 31, 2026 to close one major loophole by making licensing depend on a company's headquarters rather than the location of a foreign subsidiary, extending the restriction to Nvidia's Blackwell and Rubin product lines. But stopping cloud-based access to servers that already contain those chips is harder, and any further U.S. action could raise compliance costs for cloud providers and data center operators while adding pressure to Nvidia's already reduced China-linked business.
