Nvidia shares drop as board launches probe into CEO’s alleged espionage target

Nvidia has seen a significant reduction in its market capitalisation following the announcement of an independent investigation into the personal conduct of its chief executive. The US chipmaker reported that its shares fell by approximately four per cent by the close of trade on Monday, resulting in an estimated loss of 250 billion dollars, or 190 billion pounds, in company value. This financial downturn occurred after Jensen Huang admitted to an extramarital affair with a woman whom US intelligence officials believe was a spy for China. The board of directors stated that the probe would be conducted in light of recent reporting suggesting that Huang had been the target of a foreign intelligence effort.

The investigation was initiated after reports emerged that the US government believed Huang had been targeted in an espionage campaign by Beijing. According to a report by the New York Times, US intelligence officials identified Alice Huang, also known as Huang Le, as a spy for the Chinese government. The report further stated that Secretary of State Marco Rubio had sent a memo to senior officials in Washington last spring, warning that the Nvidia boss was in a close relationship with this individual. Alice Huang is described as the managing director of Megaspeed, a Singaporean company that has had commercial dealings with Nvidia. In response to these allegations, the Chinese foreign ministry rejected the claims, describing them as entirely groundless, speculative, and intended to smear and malign China.

Nvidia issued a statement asserting that it had no reason to believe the company’s secrets or national security were compromised. However, the board confirmed that it would begin an investigation to address the concerns raised by the recent media coverage. Jensen Huang acknowledged that he was unfaithful to his wife and apologised for the hurt caused to her and their children. He expressed his commitment to protecting Nvidia and supporting America’s national security, and stated that he would fully cooperate with the ongoing investigation. The Nvidia co-founder has also been requested to appear for a joint closed-door briefing for several Congressional committees next week to discuss his interactions with Alice Huang and the company’s security protocols.

Members of the US House Foreign Affairs Committee, including congressmen Brian Mast, John Moolenaar, and Rick Crawford, wrote a letter expressing significant national security concerns regarding China’s access to sensitive US technology and information. They emphasised the importance of Congress determining the extent to which US national security has been placed at risk. Following the announcement of the investigation, several prominent figures in the technology sector, including Elon Musk, voiced their support for Huang continuing to lead the firm. US President Donald Trump also commented on the situation, describing the Nvidia boss as an honourable guy.

Despite the negative impact on share prices, the broader US stock market opened the week on a positive note, with rival chipmakers benefiting from the shift in investor sentiment. Analysts have suggested that the hit to Nvidia’s value may be short-lived. Victoria Fernandez, chief market strategist at Crossmark Global Investments, noted that investors are unlikely to abandon the company given its central role in the artificial intelligence industry. She explained that Nvidia is the core of the AI trade, and without it, other components of the sector would struggle due to a lack of financing. Fernandez added that she does not believe the board will remove Huang as chief executive unless there is glaring evidence of wrongdoing related to national security or intellectual property, but predicted that the company may begin identifying a successor to serve as his number two.

A key concern for investors is the potential leadership vacuum should Huang be removed from the company. Fernandez noted that there is no natural successor to the chief executive. Unlike many other tech founders, such as Mark Zuckerberg of Meta or Elon Musk of Tesla and SpaceX, who hold significant percentages of multiple types of stock, Huang owns only around 3.5 per cent of Nvidia. The company operates on a single class voting structure, meaning his stake is not sufficient to act as a veto power over any board decision. This makes him vulnerable to any move by the board of directors to oust him. However, the modest fall in shares suggests that investors believe it is unlikely he will step down or be removed, although the outcome of the investigation will be closely monitored.

Nvidia, which was co-founded by Huang and two other engineers in 1993, has become the world’s second most valuable company by shifting its focus from gaming hardware to AI development. The company’s chips have been a major focus of the AI race between the US and China. The White House has previously imposed controls on where Nvidia’s advanced products can be sold, with the H200 semiconductor being restricted over concerns that it would give China’s technology industry an edge. Huang has argued against restricting the sale of these chips to China, contending that it would be better for the global rollout of AI to be powered by US technology. In January, the Trump administration announced that it would allow the company to sell its H200 chips to Chinese customers under certain conditions.
