Nvidia shares dropped 4.8 percent to $177.755 by mid-morning in New York, paring an earlier 9 percent slide after the company confirmed its board is investigating whether Chief Executive Jensen Huang was targeted by a foreign intelligence operation. The stock had closed the previous session at $186.64, giving the chipmaker a market capitalisation of roughly $4.28 trillion. The move coincided with Huang's Sunday admission of an intimate relationship with Alice Huang, a senior executive at Megaspeed, one of Nvidia's largest customers in Southeast Asia, whom US intelligence agencies have reportedly identified as a Chinese spy.
The board acts
Nvidia's directors said they have "no reason to believe" that national security or confidential company information was compromised, but opened a formal inquiry into all available information. Huang will remain chief executive during the review and has agreed to cooperate. In a message to staff, the 63-year-old founder apologised for being unfaithful to his wife and said he had fallen short of the responsibility that comes with leading the company. China's Foreign Ministry dismissed the espionage allegations on Monday as a smear campaign against Beijing.
The customer at the centre
Alice Huang, a Chinese citizen and former television reporter in China, joined Singapore-based data centre operator Megaspeed as a senior executive. According to a report last month by The Times, US intelligence agencies concluded she was passing information directly to China. Megaspeed is described as one of Nvidia's biggest customers in the region, placing the relationship at the intersection of the company's commercial interests and the geopolitical friction over advanced semiconductors.
Bernstein sees more noise than signal
Wall Street brokerage Bernstein kept its Outperform rating and $400 price target on Nvidia, arguing that several of the espionage-related claims carry "more form than substance" at this stage. The firm noted that Jensen Huang has lobbied for greater access to the Chinese market for years with limited success, making the idea that Alice Huang influenced that effort unnecessary. Bernstein also pointed out that the chips currently permitted for sale in China, the H20 and limited quantities of the H200, are lower-end products several generations behind the frontier, and that China has largely resisted buying them in favour of domestic alternatives.
What to watch
The investigation's scope and timeline remain unspecified, leaving the market to weigh a governance distraction against Nvidia's dominant position in AI infrastructure. Regulatory scrutiny could intensify if the review uncovers any mishandling of export-controlled information, even if the board's initial assessment sees no compromise. For now, the shares are trading in a $170.24 to $178.73 range, reflecting a market that has priced in the headline risk but not yet the outcome.
