Nvidia’s meteoric rise has pushed its weighting in the MSCI All-Country World Index to a record 4.96%, overtaking the entire Japanese equity market’s 4.63% share and eclipsing the combined weights of France and Germany. The milestone underscores how a single U.S. technology company has come to dominate a benchmark that tracks thousands of stocks worldwide. The chip designer’s market capitalization now stands near $4.2 trillion, equal to roughly 3.6% of global gross domestic product and about 13% of U.S. output, according to market data cited by investors. Nvidia shares have gained about 20% in the past three months, with intraday swings that at times erase or add the equivalent of another major semiconductor firm’s entire valuation. Investor enthusiasm has been fueled by Chief Executive Officer Jensen Huang’s vision for growth beyond artificial intelligence. Addressing the 2025 annual shareholder meeting, Huang called robotics a “multitrillion-dollar opportunity,” predicting billions of robots, hundreds of millions of autonomous vehicles and hundreds of thousands of robotic factories that could run on Nvidia hardware. The company is simultaneously ramping production of its next generation of AI servers, reinforcing perceptions that its dominance in advanced computing is widening.
