Nvidia passes Apple in market cap as second-most valuable public U.S. company

Actually, as of now, Nvidia is not the second-most valuable public U.S. company in terms of market capitalization. Top spots are generally occupied by companies like Apple, Microsoft, Amazon, and Alphabet (Google's parent company). The market capitalization rankings fluctuate based on the stock prices of these companies. As of my latest data update, Nvidia's market cap is impressive, but it hasn't surpassed Apple. However, the trends in the tech industry can change quickly, and it's always possible for rankings to shift. Always check the most recent and reliable financial sources for the latest information.
