Spy scandal topples Nvidia CEO, sinks Chinese AI stocks

The latest:

Chinese AI stocks sold off Friday after the departure of Nvidia chief executive Jensen Huang over a reported relationship with a Chinese businesswoman US authorities suspect of spying for Beijing. House Speaker Mike Johnson said a consensus is forming in Congress to tighten chip export limits. AI model developer Z.AI fell 12% and MiniMax Group lost 8.4%, Reuters reported.

Details:

• The scandal: Huang stepped down after reports of a romantic relationship with Alice Huang, an executive at Megaspeed, an Nvidia partner that US authorities suspect of helping China obtain advanced AI chips restricted under export controls, Reuters reported. Beijing has denied she is a spy.
• The market hit: Investors dumped Chinese AI developers and hardware suppliers exposed to US demand. Z.AI dropped 12% and MiniMax Group 8.4%, while data center suppliers Zhongji Innolight and Eoptolink Technology, both heavily reliant on US markets, each slid more than 8%.
• The speaker’s position: Johnson, a Louisiana Republican, told reporters at the Capitol that export controls on chips to China have been a major issue and that he favors limiting Chinese access to the technology. “I think there’s a developing consensus in Congress that is an important position to take,” he said.
• The legislation: Lawmakers are pushing at least four chip export bills since Monday, according to statements cited by Reuters. The AI Overwatch Act would expand congressional power over exports, while the Chip Security Act would require companies to track the physical location of advanced AI processors to block smuggling.
• Closing the loopholes: The Match Act would press US allies to restrict sales and servicing of advanced chipmaking equipment bound for China. The Remote Access Security Act would give the Commerce Department tools to stop Chinese firms renting overseas data centers to reach Nvidia chips remotely.
• The defense bill: Congressional Republicans want to attach new curbs on advanced AI chip exports to the annual defense authorization bill, a must-pass measure funding the military that usually draws bipartisan support, a Senate aide told Reuters on condition of anonymity.
• Pressure on Lutnick: Senior White House officials discussed whether Commerce Secretary Howard Lutnick should be pushed out, two people familiar with the situation told Reuters. Lawmakers have criticized the refusal to add dozens of Chinese companies to a trade blacklist and questioned oversight of Nvidia’s China exports.
• The workaround: Chinese AI companies are seeking to rent Nvidia-powered computing capacity outside China, worried the allegations against Huang could push Washington to tighten rules on remote access to the chips, Reuters reported.
• Scrutiny continues: Sunny Cheung of the Jamestown Foundation assessed that Huang’s exit will not end congressional scrutiny and could leave him more exposed, noting Congress can still subpoena him and that Nvidia should independently investigate whether the problems extend beyond him.

Background:

Washington has restricted Chinese access to Nvidia’s advanced AI chips for years to keep them from benefiting the Chinese military. Huang had lobbied to preserve access to the Chinese market and maintained close ties with President Donald Trump.

Between the lines:

Cheung assessed that Huang’s departure weakens Nvidia’s lobbying weight in Washington and adds momentum to the export bills now moving, and that new leadership may rethink the company’s China strategy to rebuild trust with policymakers. The Friday selloff in Z.AI, MiniMax and the two data center suppliers suggests investors are pricing the espionage case as a regulatory event rather than a corporate one.

What’s next

Huang is expected to testify before Congress ahead of Thanksgiving on November 26. House Foreign Affairs Chairman Brian Mast said staff spoke with Nvidia on Wednesday night about a date and location. Watch the defense authorization bill for attached chip curbs.
