Nvidia was the first semiconductor maker to become the world’s most valuable publicly traded company.
Nvidia reached the top of global market-cap rankings in 2024, driven by extraordinary demand for its graphics processors and networking systems for artificial intelligence. The achievement was historically notable because semiconductor companies had generally ranked below the largest consumer-technology and software businesses.
Nvidia began as a graphics-chip designer for computer games but expanded into parallel computing. Its GPUs proved especially useful for training neural networks, and the company built a large software ecosystem around them. That combination helped turn AI infrastructure into its central growth story.
The ranking should not be confused with being the largest semiconductor manufacturer by physical production. Nvidia primarily designs chips and relies on foundries such as Taiwan Semiconductor Manufacturing Company for fabrication.
