Nvidia becomes most valuable public company, topping Microsoft and Apple

On Tuesday, Nvidia leapfrogged two of tech’s most storied names to become the world’s most valuable public company, according to data from S&P Global. Its ascent has been powered by the boom in generative artificial intelligence and surging demand for the company’s chips — known as graphics processing units, or GPUs — which have made it possible to create AI systems.
