- Lead. Senator Elizabeth Warren has demanded that Nvidia answer detailed compliance questions by June 18, after CEO Jensen Huang declined an invitation to testify before the Senate Banking Committee on AI chip sales to China.
- Fact. Department of Justice enforcement actions allege that schemes routed $510 million in Nvidia servers and $160 million in H100 and H200 chips through third countries — including Malaysia and Thailand — in violation of US export controls, directly contradicting Huang’s public claims of zero diversion and zero China market share.
- Stake. The probe comes after the Commerce Department clarified on June 1 that export licence requirements apply to Chinese companies’ overseas units, tightening the controls at the same moment Nvidia’s compliance practices face the most sustained congressional scrutiny in the company’s history.
The sequence started in early June. Warren invited Jensen Huang to testify at a Senate Banking Committee hearing on AI and the American economy, asking him to confirm his attendance by June 8. On June 8, Huang declined. Warren then shifted to a written compliance demand, addressing the letter not to Huang but to Nvidia’s General Counsel Tim Teter and Audit Committee Chair Brooke Seawell — a choice that signals a specific interest in board-level oversight of export compliance rather than CEO-level strategy.
The June 18 deadline asks Nvidia to respond to a set of detailed questions about its compliance programme and the accuracy of its public statements. Warren cited multiple recent DOJ enforcement actions that allege coordinated schemes to divert Nvidia products: millions of dollars in GPUs routed through Malaysia and Thailand, an estimated $160 million in H100 and H200 chips, and a total of $510 million in diverted servers. Those figures sit awkwardly against Huang’s repeated assertions that Nvidia maintains zero exposure to the Chinese market through diversion.
The export control tightening
The timing of the probe intersects with a broader tightening of the US chip export framework. On June 1, the Commerce Department issued guidance clarifying that export licence requirements apply to all businesses with Chinese headquarters or a Chinese parent company, regardless of where the chips are shipped. The clarification was aimed at closing the gap between formal restrictions and the de facto channel through which Chinese entities had been accessing advanced AI hardware — overseas subsidiaries in Southeast Asia and the Middle East.
For Nvidia, the implications are layered. Earlier this year, H200 chip sales to third-country buyers were cleared by Washington while Beijing continued to restrict use of those chips within China. The new June 1 guidance changes the compliance picture for those transactions when the ultimate end-user has Chinese ownership. Huang accompanied Trump to Beijing earlier this year in an effort to broker a commercial resolution to the H200 stalemate, a mission that now looks more complicated as Warren’s investigation sharpens the question of whether Nvidia’s compliance mechanisms are adequate for the rules already on the books.
What happens next
If Nvidia meets the June 18 deadline, its written response will set the factual record for the committee’s next steps, which could include a subpoena for documents or a compelled hearing. If it misses the deadline or provides an incomplete response, Warren has the procedural tools to escalate within the Banking Committee. Separately, the DOJ cases underlying Warren’s letter are active and the criminal exposure sits independently of whatever Nvidia says to Congress. The company’s share price and its position at the centre of the global AI infrastructure build-out give the investigation a market dimension that goes well beyond a standard export control audit.
