NVDA Stock Slips After Hours As Warren Reportedly Calls Huang To Testify On China Chip Sales

• In the letter, Warren wrote that testifying would give Huang “an opportunity to testify about NVIDIA’s views on U.S. export control laws and regulations and NVIDIA’s business in China.”
• Huang has till Monday to confirm his appearance. 
• Nvidia has held that its market share in China has fallen sharply.

Shares of Nvidia (NVDA) fell 1% in after-hours trading on Thursday following a report that Sen. Elizabeth Warren invited CEO Jensen Huang to testify before the Senate Banking Committee on the company’s China business and compliance with U.S. export controls on advanced AI chips.

CNBC was first to report that Warren, D-Mass., sent a letter inviting Huang to appear at a June 11 hearing.

In the letter, Warren wrote that testifying would give Huang “an opportunity to testify about NVIDIA’s views on U.S. export control laws and regulations and NVIDIA’s business in China.” She asked the CEO to confirm his attendance by Monday.

The invitation comes weeks after Huang joined President Donald Trump on a summit trip to Beijing, where he met Chinese President Xi Jinping. It also coincides with separate Republican-led efforts in the House Energy and Commerce Committee to investigate alleged Chinese efforts to impede U.S. AI and data-center development.

Nvidia’s China Business

Before sweeping export controls began in 2023, China accounted for 13-20% of Nvidia’s revenue in some periods, mostly from data-center chips. Successive administrations have restricted sales of high-end GPUs such as the H100, H200, and Blackwell series, citing national-security risks.

Nvidia has responded by developing compliant lower-performance chips, notably the H20. Even those sales have been volatile: the company took a $4.5 billion charge in fiscal 2026 related to H20 inventory after new licensing rules. Under the current Trump administration, the Commerce Department has allowed resumed H20 shipments, sometimes with conditions requiring a portion of revenue to flow back to the U.S. government.

Lawmakers from both parties have expressed concern about the possible diversion of chips to China through third countries. Nvidia has maintained that it has seen “no evidence” of widespread diversion and that its market share in China has fallen sharply.
