Nvidia surpassed Microsoft in market capitalization, becoming the world's most valuable publicly traded company. Nvidia's shares rose, pushing its market cap to approximately $3.45 trillion, slightly ahead of Microsoft's $3.44 trillion. This surge is primarily driven by the immense demand for Nvidia's AI chips, which are central to the current artificial intelligence boom. This isn't the first time Nvidia has held the top spot, as it has been trading places with Microsoft and Apple at the top of the market capitalization rankings since June 2024.
