Kalshi traders speculate Nvidia's Ian Buck will replace Huang as CEO - CNBC

Kalshi traders are speculating on who could replace Jensen Huang as CEO of Nvidia after the co-founder of the dominant AI chipmaker abruptly resigned on Thursday, following reports of two affairs.  

Kalshi traders give Ian Buck, the vice president overseeing the company's hyperscale and high-performance computing business, a 35% chance of replacing Huang.

Traders give Colette Kress, the Nvidia chief financial officer and interim CEO, a 29% chance of taking over full time.

The Kalshi contract asks '"Who will be the next CEO of Nvidia?" and will be verified by news reports.

Huang first admitted to having an affair on Sunday with a woman that U.S. intelligence agencies claim is a spy for China's Ministry of State Security, according to the New York Times. Nvidia's board of directors opened an internal investigation into the relationship, which was quickly followed by a second Times report Wednesday that Huang had a second affair, with Kimberly Powell, a subordinate in charge of the company's healthcare. 

CNBC confirmed Nvidia's board met late Wednesday night to decide whether to oust Huang. 

In recent trading, Nvidia shares were down a little more than 7% after earlier falling as much as 14.4%.

Disclosure: CNBC and Kalshi have a commercial relationship that includes customer acquisition and a minority investment.

Correction: This story has been revised to reflect that Nvidia's interim CEO is Colette Kress. A previous version misspelled Kress' name.
