Key Highlights

  • Chairs of three House committees wrote to Nvidia (NASDAQ:NVDA) chief executive Jensen Huang on November 9, 2026, asking him to attend a joint, closed-door briefing on November 18.
  • The letter seeks information on the company's "security protocols against foreign adversary espionage" and Huang's interactions with a former Megaspeed executive reported to be a Chinese intelligence asset.
  • Democratic Senator Elizabeth Warren separately said Huang and the board "owe Congress answers" and urged passage of legislation to stop advanced American technology from reaching China.
  • Nvidia shares fell 4.27% to USD 178.67 on November 9, and it remains unclear whether Huang will attend on the proposed date.

What Lawmakers Are Asking

The request came from the chairs of the House Select Committee on the Chinese Communist Party, the House Foreign Affairs Committee and the House Intelligence Committee. They wrote that "it is vital that Congress determines the extent to which U.S. national security has been placed at risk." The letter allows Huang to propose an alternative date while the current Congress is in session, so November 18 is a requested date rather than a subpoena. The focus is on Nvidia's internal safeguards and on whether information about chips, customers or China sales could have been exposed. Reports also say a senior administration official warned colleagues about the relationship months ago, and a short seller has said it flagged Nvidia's exposure to Megaspeed earlier this year, though neither claim has been confirmed by the company. The committees have become central voices on technology competition with China, and their requests tend to shape later legislation on export controls.

The Megaspeed Connection

Megaspeed International, based in Singapore, became one of Nvidia's largest buyers, with roughly USD 4.8 billion of equipment purchases. US authorities have examined the company since 2024 over suspicions that it helped route advanced processors into China in breach of export controls, with alleged diversions of about USD 2 billion of AI chips. Nvidia's most advanced Blackwell processors are banned from export to China, while sales of the older H200 were permitted from December 2025. One report says Nvidia previously intervened to halt a US probe into Megaspeed, a claim that, if substantiated, would sharpen congressional focus. Nvidia's board has said it has no reason to believe national security or company secrets were compromised, and no charges have been brought against anyone involved. The former executive has not publicly responded to the reports, and her whereabouts are unknown.

Why It Matters for Shareholders

Congressional scrutiny raises policy risk more than legal risk. Lawmakers could push for stricter licensing of overseas distributors, tighter end-use checks or new limits on chip sales to Chinese-owned firms operating outside China. Any of those would add compliance cost and could reduce sales in Asia. A closed-door format limits the risk of damaging public testimony, but leaks are common, and repeated hearings would keep the story in the headlines into Nvidia's Earnings report on November 17 and beyond. President Trump has publicly backed Huang, which reduces the risk of executive action, but Congress can legislate independently. Investors will watch whether Huang attends, what the board's independent review finds and whether bipartisan export legislation gains momentum.

Where Things Stand

House committee chairs have asked Jensen Huang to brief lawmakers behind closed doors on November 18, 2026 about Nvidia's security protocols and his contacts with a former Megaspeed executive. The request adds political pressure while the board's own review continues. Nvidia reports earnings on November 17, one day earlier, so the two events will shape sentiment toward the stock in the same week. Any decision by Huang on attendance will itself be read as a signal.
