For over three decades, Jensen Huang has been the face of Nvidia. In his signature black leather jacket, the company’s co-founder and CEO has become one of Silicon Valley’s most recognizable figures, leading the chipmaker from a graphics processor business into the engine powering the AI boom.

Now, his tenure has ended abruptly. Nvidia said Thursday (Nov. 12) that Huang had resigned as president, CEO, and board member, effective immediately. The company said its chief financial officer, Colette Kress, will serve as interim CEO while the board searches for a permanent successor and considers internal and external candidates.
