U.S. AI chip export clarification may hit Nvidia, AMD

The Commerce Department’s Bureau of Industry and Security issued guidance over the weekend extending export license requirements to advanced AI processors sold to buyers whose ultimate parent companies are based in China. The clarification closes a loophole that allowed some high-end chips to be routed through foreign subsidiaries and distributors.

The guidance covers top-tier accelerators, including Nvidia’s Rubin and Blackwell families and AMD’s MI350x. Licenses will now be required for sales to any buyer whose ultimate parent is located in China, regardless of the buyer’s operating country.

The administration rescinded broader Biden-era global export restrictions last May, creating an enforcement gap that industry sources say allowed hundreds of thousands of advanced chips to reach firms linked to China through overseas subsidiaries. Singapore and Malaysia were identified as suspected routing hubs in those diversion patterns.

Market effects may be limited initially. Existing licensed sales of lower-tier products remain under prior terms and products already shipped remain with customers. Earlier drafts of similar export curbs reduced Nvidia shares about 1.8% and AMD shares about 2.2% in trading sessions.

Nvidia reported zero Data Center Hopper shipments to China in fiscal first quarter 2027, down from $4.6 billion a year earlier. Nvidia’s overall Data Center revenue reached $75.2 billion, driven by demand for the Blackwell 300 family.

Exporters must now verify the ultimate parent of each buyer instead of relying only on the destination country. Distributors, cloud resellers and other intermediaries face tougher know-your-customer checks, and companies that missed diversion channels during the enforcement gap may face government scrutiny.

Federal prosecutors previously charged operators of a GPU smuggling ring valued at about $2.5 billion that used similar diversion schemes. Since 2024, the government has layered entity-specific restrictions and region-focused curbs on top of the China framework; the new guidance keeps those entity-level controls in force.

Exporters will be required to seek licenses and to demonstrate that end users are not ultimately controlled by Chinese parent companies. The full commercial impact will become clearer when semiconductor companies report next-quarter results and provide updated regional shipment disclosures.
