Global AI stocks sink as Nvidia CEO's exit deepens sector concerns

Global AI-linked stocks experienced a significant drop on Thursday following Nvidia CEO Jensen Huang's resignation amid a scandal involving his affairs. The chipmaker's leadership change and the scandal pose fresh risks to a sector already grappling with funding and regulatory concerns. Colette Kress will serve as interim CEO as Nvidia seeks a permanent successor.

As a key player in the AI ecosystem, Nvidia's chip infrastructure financing has drawn scrutiny over circular funding, potentially impacting the sector. Nvidia's shares plummeted 8.2%, reaching a 16-month low, and its market value edged below $4 trillion for the first time since July 2025. Industry experts question whether the leadership vacuum could hinder funding for smaller AI companies.

Neocloud firms like CoreWeave and IREN suffered sharp declines, while other companies such as Marvell Technology, Oracle, Micron Technology, and Dell Technologies also experienced losses. Competitors like AMD and Broadcom, however, saw gains. The turmoil at Nvidia has stirred concerns about potential regulatory hurdles and the broader impact on tech markets worldwide, with Japan, South Korea, and Europe also witnessing declines.

Nvidia's market value has plummeted by over $550 billion since the investigation into Huang's relationship with a Chinese businesswoman was announced, and shares trade at a 12-month forward earnings estimate of 12 times, the lowest since November 2012.
