U.S. lawmakers press to halt Nvidia exports to China
After uncovering a major smuggling operation, U.S. senators are calling for suspension of Nvidia AI chip export licenses to China and Southeast Asia — a fresh policy risk for advanced compute supply to the region. The move underscores rising political pressure to tighten export controls and track advanced chips more closely. (ft.com)
Senators Elizabeth Warren (D‑Mass.) and Jim Banks (R‑Ind.) sent a letter to Commerce on March 24, 2026 urging immediate action on Nvidia-related export licences. (banking.senate.gov)) A separate DOJ enforcement action dubbed “Operation Gatekeeper” said agents seized more than $50 million in Nvidia technologies and identified schemes that moved at least $160 million in H100 and H200 GPUs between October 2024 and May 2025. (justice.gov)) Federal prosecutors unsealed an indictment on March 19, 2026 charging three people connected to Super Micro with diverting roughly $2.5 billion of Nvidia‑powered servers to China, including about $510 million of shipments in a short mid‑2025 window. (bloomberg.com)) The senators asked the Commerce Department’s Bureau of Industry and Security (BIS) to pause and review all active export licences covering advanced Nvidia GPUs and server systems destined for China and specific Southeast Asian countries. (banking.senate.gov)) Their letter cites Nvidia CEO Jensen Huang’s prior public assurance that “there’s no evidence of any AI chip diversion,” and urges reconsideration of licence reliance on vendor assurances given the alleged diversions. (banking.senate.gov)) The Super Micro indictment alleges use of “dummy” servers, falsified paperwork and physical tampering — including removing and re‑affixing serial numbers with a hair dryer — to conceal real shipments bound for China. (bloomberg.com)) News of the charges drove immediate market moves: Super Micro shares plunged roughly 33% on publication of the indictment, wiping billions off the company’s market value.
