House Foreign Affairs Chair Threatens to Subpoena Nvidia CEO Jensen Huang Unless He Responds by November 11

• Dispatched: Nov 10, 2026 · 19:38 ET (Nov 11, 00:38 UTC)

One-sentence summary: House Foreign Affairs Committee Chairman Brian Mast told ABC News on November 10 that he is prepared to subpoena Nvidia CEO Jensen Huang if Huang does not respond by Wednesday, November 11, to a request for a closed-door briefing from three Republican committee chairs — the first threat of compelled testimony in the probe into Huang's reported dealings with a suspected Chinese intelligence operative, one week before the briefing is scheduled for November 18.

Verification status: ✓ The subpoena threat is cross-confirmed by ABC News, Bloomberg and Decrypt and is an on-the-record statement by the committee chair; no subpoena had been issued at the time of reporting. The underlying allegations about Huang's dealings with a suspected Chinese intelligence operative are not yet confirmed.

Core Facts & Consensus Delta:

Mast told ABC News on November 10, 2026, at 16:37 ET / 21:37 UTC that he would "absolutely" consider a subpoena if Huang did not respond. Bloomberg reported the remarks earlier the same day at 14:45 ET / 19:45 UTC; Decrypt followed at 15:45 ET / 20:45 UTC.

The briefing request dates to a November 4 letter from three Republican chairs — Mast (Foreign Affairs), Rick Crawford (Intelligence) and John Moolenaar (Select Committee on China) — asking Huang to attend a joint closed-door briefing on November 18 to explain his interactions with Alice Huang, a Megaspeed executive U.S. intelligence agencies have identified as a suspected Chinese intelligence asset, and Nvidia's safeguards against foreign espionage. As of the reports, Huang had not responded, and no criminal charges have been filed against him.

Quantitative context: Nvidia's board announced an independent investigation on November 8, led by former federal prosecutor Joon H. Kim and Wachtell, Lipton, Rosen & Katz. Nvidia shares closed November 10 down 5.47% at $168.89, a two-day fall of about 9.5% that took the stock below its end-2025 close of $186.50, erasing its 2026 gains.

Supply-Chain & Market Read-Through: The escalation turns a corporate-governance inquiry into congressional compulsion risk days before Nvidia's November 17 earnings. If Huang responds and attends the November 18 briefing, lawmakers are expected to press on export-control compliance and distributor oversight, which could yield new security-review demands; if he misses the November 11 deadline and a subpoena follows, the prospect of compelled testimony raises disclosure pressure even though such a subpoena would likely expire when Democrats take control of Congress in January.

For the memory chain, the transmission runs through risk pricing rather than orders: Nvidia is the anchor demand driver for HBM and for the memory makers — SK Hynix (KRX: 000660), Samsung Electronics (KRX: 005930), Micron (MU) and SanDisk (SNDK) — and the largest source of CoWoS advanced-packaging demand. This item alone does not change HBM supply or demand fundamentals, but prolonged leadership uncertainty at Nvidia adds to the AI-spending risk premium already weighing on memory names, which fell on November 10 alongside the hotter-than-expected October CPI. It should be read separately from The Information's November 10 report of roughly 240,000 chips worth at least $7.5 billion allegedly reaching China, which is single-source and ⚠ Single-source / Unconfirmed.

Next Catalysts & Watchpoints:

• November 11, 2026 (Wednesday): Huang's deadline to respond to the three committee chairs — watch whether he accepts the November 18 briefing or proposes an alternative date.
• November 17, 2026: Nvidia's fiscal Q3 2027 results (release around 16:20 ET, call at 17:00 ET) — management's first earnings-call comments on the investigation and its China business.
• November 18, 2026: scheduled date of the joint closed-door House briefing — watch whether it proceeds and whether a subpoena is issued.
