    Nvidia Surpasses Apple as Largest Holding in S&P 500 Index Funds

    Question

    Nvidia Surpasses Apple as Largest Holding in S&P 500 Index Funds

    Direct answer

    Nvidia has officially overtaken Apple as the dominant constituent in major S&P 500 index funds. This shift reflects the massive market cap expansion driven by AI demand over the last two years. For index investors, this creates a high level of idiosyncratic risk tied to a single company's earnings and the broader AI infrastructure cycle.
