Nvidia became the first publicly traded company in the world to reach a $4 trillion market capitalization on Wednesday, with shares climbing to an all-time high of $164 amid surging demand for artificial intelligence technologies, as analysts highlight the company’s unmatched dominance in high-performance chips and infrastructure innovation—including a shift to liquid-cooled systems—that continues to drive investor confidence, while portfolio manager Brian Mulberry attributes the milestone to Nvidia’s consistent earnings outperformance, expanding product lineup, and leadership in compute power, all of which underscore Wall Street’s bullish outlook on AI despite earlier sector jitters from emerging competition, with Microsoft trailing as the second-most valuable U.S. company at $3.74 trillion.
