Nvidia shares plunge 10% after CEO Jensen Huang resigns

Nvidia shares plunged 10% to $148.80, their lowest since mid-2025, after Jensen Huang resigned as CEO, dragging the S&P 500 and Nasdaq lower on Thursday. The leadership crisis follows days of turmoil over Huang's admitted affair and a reported relationship with an Nvidia executive. The S&P 500 fell 0.36% to 7,591.77, while the Nasdaq 100 dropped 0.77% to 28,155.86. Other chip stocks declined, including Dell, Micron, Marvell, and Intel, each down 4-5%. Investors cited "key man" risk, as Huang is considered the face of the AI boom since late 2022. Analysts are split on the impact, with some advising continued buying ahead of earnings, while others warn of longer-term harm to the AI ecosystem. Huang's departure raises questions about AI regulation leadership and Nvidia's future direction.
