Nvidia's board has launched an independent investigation into national security allegations involving Chief Executive Jensen Huang. On Nov. 9, U.S. authorities were examining how Huang's personal relationship with a Megaspeed executive suspected of links to Chinese intelligence affected Nvidia's lobbying for chip sales to China, The Verge reported.

Megaspeed is a Singapore-based cloud company and a major Nvidia customer. U.S. authorities believe one of the company's executives could be a foreign intelligence asset who passed information to the Chinese government. They also suspect Megaspeed and its Malaysian affiliate secured large quantities of Nvidia chips through links to Chinese corporate networks, with some possibly brought into China. The Malaysian affiliate was reported to have spent more than $4.8 billion on Nvidia chips and technology from June 2024 to February 2026.

The controversy grew alongside questions about Huang's lobbying role. He has sought looser U.S. semiconductor export restrictions to China from the Trump administration and Congress. Nvidia said meetings with customers are part of a CEO's job, but U.S. authorities believe security concerns rose after the two developed a private relationship.

The timing also overlaps. The Trump administration imposed new restrictions on the China-bound H20 chip in April 2025. Huang was later reported to have met U.S. President Donald Trump at the White House in July that year and asked for eased export restrictions. Days later, Nvidia said sales of the H20 to China were allowed. Huang has argued that U.S. technology can become the standard only if U.S.-made chips are supplied to China.

In October 2025, he also asked for permission to sell higher-performance chips to China ahead of talks between Trump and Chinese President Xi Jinping, but Trump did not pursue it. In December 2025, however, sales of the H20 were allowed only to approved customers in China, and 25 percent of the revenue was to go to the U.S. government.

Inside the Trump administration, a classified memo on the matter circulated this spring. Trump later said in a briefing that the issue did not have a major effect on him, and over the weekend he described Huang as an honourable person.

Huang admitted an extramarital affair in an internal memo and apologised to family members and employees. Nvidia said he would continue to lead the company during the investigation. It also said there was no reason so far to believe national security or company secrets had been compromised.
