Nvidia shares sink as board launches probe into Jensen Huang's affair

• Very little of consequence happens in AI without Nvidia's involvement, and that usually means the imprint of Jensen Huang himself.

By the numbers: Nvidia shares were off 4.4% in premarket trading as of 5:15 a.m. ET Monday, on a day that tech stocks were otherwise broadly higher.

• That would represent a loss of about $199 billion in regular trading.
• It's a relatively small move for the world's second-largest company by market capitalization — but a blow nonetheless to investors.
• Through Friday, the stock had already lost 13% of its value since the initial reports that the U.S. government was concerned about Jensen Huang's relationship with Asian tech executive Alice Huang.

Stunning stat: Monday's move would be the equivalent of a $7.1 billion hit to Huang personally.

What to watch: Given how central Nvidia is to the AI ecosystem, its weakness could reverberate in coming days.

• "This is a black eye moment for Jensen and will spark multiple congressional inquiries at a minimum and will create an overhang," noted AI bull and Wall Street tech analyst Dan Ives posted to X.
