Nvidia has overtaken Microsoft and Apple to become the world's most valuable publicly listed company, boasting a market cap of $3.34 trillion. The AI chip giant's shares are trading at around $135 following a 10-for-1 stock split in June. The move was aimed at securing Nvidia's place on the Dow Jones Industrial Average. Nvidia, originally a gaming company, has shifted its focus to AI technology. The firm's graphics processors are popular among industry leaders like Google and Amazon for developing AI systems. Nvidia's Q1 results showed $26 billion in revenues, prompting the CEO to announce annual releases of new AI chipsets.
