Approximately $430 billion in market value has reportedly disappeared across the two sessions as investors confront allegations involving CEO Jensen Huang’s personal relationship with a businesswoman suspected of connections to Chinese intelligence. Independent directors have retained Wachtell Lipton, including former prosecutor Joon Kim, to investigate whether the relationship involved foreign intelligence activity or compromised company information. The allegations remain under investigation, and Nvidia says it has no reason to believe secrets or national security were compromised. Nevertheless, Nvidia’s extraordinary valuation depends partly on confidence in Huang’s leadership, making executive continuity and China-related export exposure unusually consequential.

And so, what we’re doing with China is bumpy right now.” Introduction: Nvidia, down $430bn, hires major US law firm to investigate alleged Chinese spy affairGood morning, and welcome to our rolling coverage of business, the financial markets, and the world economy.The crisis gripping Nvidia is gathering pace, with around $430bn wiped off the value of the world’s most valuable company since it was hit by a spying scandal.Overnight, Nvidia announced it has hired a former top federal prosecutor to help probe chief executive Jensen Huang’s relationship with a suspected Chinese spy.The company’s board have retained Joon H.
