Nvidia CEO Jensen Huang stepped down on Thursday after reports of an extramarital affair, one of which allegedly involved a suspected Chinese spy. The company's board had met late Wednesday to decide whether to oust him, and the reports fuelled a market sell-off and raised questions about the leadership of the world's dominant AI chip supplier. France 24 reported that Nvidia announced the departure because the alleged affair raised security concerns, and Deutsche Welle reported that Huang resigned as the head of the AI chipmaker. Both outlets describe the same departure. On Thursday China accused the United States of fabricating spy narratives to justify a technology blockade, pushing back against reports that the woman was a Chinese intelligence asset. The sources do not say who will succeed him.
