Nvidia shares fell in overnight trading after the company's board said Sunday it had opened an independent investigation into reports that founder and chief executive Jensen Huang was the target of a foreign intelligence effort^1,5,7.

Bloomberg said the stock was down about 4.2% on Robinhood late Sunday night New York time⁷. Moneycontrol, carrying Bloomberg earlier, put the same session's drop at about 3.7% on that platform⁶. Figures can differ by venue and timestamp^6,7.

Huang emailed employees on Nov. 8 that the board had begun the inquiry and that he would cooperate². A company spokesperson told CNBC Huang is committed to continuing as CEO without interruption^1,3.

The board said a committee of independent directors, assisted by outside independent counsel, will oversee the work^2,5. It said it has no reason to believe U.S. national security or Nvidia secrets were compromised, and that the inquiry will examine all available information^1,5.

The reports center on Alice Huang, an executive affiliated with Megaspeed, a cloud company that is an Nvidia customer^1,3. Accusations that she passed information to Beijing, and that Megaspeed helped restricted Chinese companies obtain Nvidia AI chips, rest on earlier accounts cited by CNBC, not on documents published with Sunday's statements^1,3.

The United States restricts Nvidia's most advanced AI chips for China while allowing some older, slower models¹. Nvidia had previously said meetings with customer executives are ordinary, that regional cloud customers do not receive trade secrets or national-security information, and that it had checked Megaspeed for illegal chip diversion, Business Insider and CNBC reported^3,4.

Business Insider noted that characterization came days before Huang's Sunday memo, in which he said he had been unfaithful to his wife⁴. The board statement did not mention a personal relationship^2,5.

Moneycontrol said the stock was about 22% below its October high and that Nvidia is scheduled to report quarterly results in the following days⁶. Bloomberg said shares of Nvidia's Asian suppliers largely shrugged off the news⁷.

That Moneycontrol account also said President Donald Trump called Huang a fine person and said he should stay as leader of the chipmaker; the White House comment was not independently confirmed in the other outlets reviewed⁶.

Reuters reported South Korea's deputy science minister said Monday that contracted GPU deliveries were expected to proceed without disruption⁸. The same report said Madison Huang cancelled some planned Seoul appearances, while Nvidia AI Day Seoul was described as going ahead⁸.

Three House Republican committee chairs had already asked Huang to a closed-door briefing on Nov. 18, the day after Nvidia's scheduled third-quarter earnings, CNBC reported³. Whether he will appear was not confirmed in the accounts reviewed³.

What the independent inquiry will conclude, whether any classified or trade-secret information changed hands, how regular-session trading will compare with overnight prints, and whether Huang's role changes remain unknown^1,5,7.
