Nvidia CEO Jensen Huang revealed he “had no idea how” to start a business when he co-founded the chip company from a Denny’s booth in 1993. Despite that, Nvidia has now become the world’s first $5 trillion company, after its stock rose 3% on Wednesday following Huang’s plan to build supercomputers for the U.S. government. Nvidia’s stock has jumped 50% in 2025, driven by the AI boom. Founded by Huang and two friends, the company survived early struggles in the 1990s and grew from a small video game chip maker into a global tech giant.
