The abrupt resignation of longtime CEO Jensen Huang amid a personal scandal has triggered an open search process that slightly favors external candidates at 51.5% implied probability over internal at 44.5%. NVIDIA's flat structure left no obvious successor despite its AI leadership, with internal options like hyperscale executive Ian Buck—key to CUDA development—and interim CFO Colette Kress offering continuity in chip architecture and operations. External contenders such as Arm CEO Rene Haas bring broader semiconductor and industry experience amid regulatory and geopolitical pressures on data centers and AI. The close split reflects uncertainty over whether technical depth or fresh leadership better sustains growth, with the board still selecting a search firm and no timeline set.
