Nvidia Corp. shares plunged as much as 8.8% on Monday, wiping out nearly $400 billion in market capitalization in a single trading session. Wall Street dumped the semiconductor heavyweight after Chief Executive Officer Jensen Huang disclosed an extramarital relationship with a former customer executive suspected by US intelligence of ties to a Chinese spy agency. The selloff was swift. Traders liquidated positions across New York exchanges as the 63-year-old executive circulated an internal staff confession, forcing the board to initiate an independent investigation into whether corporate assets or state secrets were compromised.
"I was unfaithful to my wife," Huang wrote in the employee memo. "My actions hurt her and our children. There is no excuse for what I did. I am deeply sorry." Huang had previously described his dealings with the woman—identified as former Megaspeed International executive Alice Huang, also known as Huang Le—as normal. The Singapore-based customer confirmed she is no longer employed there, while Chinese Foreign Ministry spokesperson Guo Jiakun dismissed allegations that she acted as a state operative, describing the claims as an unsubstantiated smear against China.
Nvidia's board convened a committee of independent directors to direct the probe alongside external legal counsel. In a regulatory filing, directors stated they retain confidence in Huang and have "no reason to believe that either national security or Nvidia secrets were compromised." Yet the inquiry will scrutinize all communications, data logs, and commercial engagements tied to the Singapore account. The disclosure delivered an immediate shock to global equity desks, where Huang has stood as the face of the enterprise artificial intelligence expansion.
"It brings the stewardship of one of America's most important companies, and the architect of the US AI trajectory, under debate, as well as calling judgment into account," Bernstein analyst Stacy Rasgon stated in a research note.
The market reaction reflects deep structural exposure. Nvidia supplies accelerator silicon to frontier research labs such as OpenAI and cloud infrastructure providers including CoreWeave Inc., while coordinating a $500 billion data-centre financing effort with institutional banks. A leadership vacuum leaves institutional investors exposed. "Jensen is a very unique CEO," said Daniel Newman, chief executive of the Futurum Group. "There is no known succession plan. There are no leaders in his company that would be the clear next to step up."
Congressional pressure is mounting in Washington. Key House Republicans demanded a formal briefing with Huang to determine whether export-restricted technology roadmaps were exposed during the relationship. US President Donald Trump defended the chief executive on Sunday, calling Huang a "fine person" who should stay in his post, though he conceded to reporters that "you never know what is going on." Independent legal counsel will present preliminary findings to the board as committee briefings proceed on Capitol Hill.
