Nvidia Drops About 5% Premarket as Aletheia Downgrade Adds to Huang Inquiry Pressure

CNBC said the shares had fallen about 5% early in the session before trimming the loss to 4.4% by around 4 a.m. New York time. The two pressures are different in kind. The board inquiry is about governance and possible security exposure at the top of the company. Aletheia's downgrade is about Nvidia's balance sheet, and how far it is tied to smaller cloud operators that rely on it to keep buying chips.

The board's investigation concerns Huang's relationship with Alice Huang, an executive at cloud company Megaspeed. The New York Times and the Financial Times reported that US intelligence agencies believe she has passed information to Beijing. Nvidia said Huang had been the target of a "foreign intelligence effort" and that he "fully supports the review and has committed to cooperating with it." In an email to staff, Huang said he had "fallen short" of his responsibilities and admitted being unfaithful to his wife. China's foreign ministry spokesperson, Guo Jiakun, said the "so-called Chinese spy narrative" was unsubstantiated.

Aletheia moved Nvidia to Hold from Buy and withdrew its $340 price target, according to Investing.com. Analyst Stefan Chang said Nvidia's AI Computing Partner programme had raised its financial commitments more than tenfold, to $165 billion in the company's fiscal second quarter of 2027. He said a financial guarantee for an Ohio data centre project accounts for $105 billion of that exposure. In his view, the programme has turned Nvidia from a hardware supplier into a financial backer of the neocloud operators that rent out its chips.

Chang estimated that CoreWeave, Nebius and IREN need $124 billion over the next 12 to 15 months to sustain 3.5 to 4 gigawatts of capital spending. He also put the cost of bringing a further 11 to 12 gigawatts online by 2030 at $450 billion to $500 billion. He wrote that the capital window for these builders "remains opaque, representing an implicit structural risk." Aletheia's concern is how that build-out is financed, not demand for Nvidia's chips.

The two threads meet in a point made by Joachim Klement of Panmure Liberum, who told CNBC that the damage was so far limited to Nvidia. If Huang's position came under threat, he said, Nvidia might scale back its support for other companies, and the selling could spread to other semiconductor stocks. Intel, Marvell, Qualcomm and Arm were each down more than 1% in premarket trading.

Dan Ives of Yorkville Ives & Co. called the episode a "black eye moment" for Huang. He said there was a clear risk Huang could be removed as chief executive depending on what the board finds, and that scrutiny of Nvidia's chip sales to China would increase. On Sunday, President Donald Trump called Huang "an honorable guy" but said he had not spoken to him about the investigation.

The sell-off follows a sharp fall in technology stocks last week, after Democrats won control of Congress and investors began to rethink the pace of data centre construction.

Nvidia reports third-quarter results on November 17, its first chance to address both the board inquiry and its customer financing commitments with investors. It also holds a major conference in Washington, D.C., at the end of the month.
