Vanguard's S&P 500 ETF Tops $700 Billion in Assets, Continues to Dominate ETF Market

Vanguard's S&P 500 ETF (VOO) has surpassed $700 billion in assets under management, becoming the first ETF to do so. The milestone reflects client preference for low-cost, passive strategies and underscores Vanguard's dominance in the ETF market. Despite macroeconomic uncertainty, clients continue to invest in large-cap US equities, with VOO up 10% in 2025 and taking in nearly $79 billion in flows.

Vanguard's S&P 500 ETF (VOO) has achieved a significant milestone by surpassing $700 billion in assets under management, becoming the first ETF to do so. This remarkable feat underscores the growing preference among investors for low-cost, passive investment strategies and highlights Vanguard's dominance in the ETF market.

The ETF's success is driven by several factors. Firstly, VOO's ultra-low expense ratio and investor-friendly reputation have attracted a large number of cost-conscious retail investors and advisors. Secondly, the fund's tax efficiency, due to its open-end structure and in-kind creation/redemption mechanisms, has further enhanced its appeal. Additionally, VOO's ability to lend out shares to earn extra and reinvest dividends in the index until paid out quarterly has boosted its returns.

Despite macroeconomic uncertainty and concerns about overvaluation, clients have continued to invest in large-cap US equities. So far in 2025, VOO has experienced a 10% increase, with nearly $79 billion in flows. This strong performance is partly attributable to the exceptional performance of tech giants like NVIDIA and Microsoft, which account for approximately 7% each of the fund's basket. The S&P 500's solid surge, driven by optimism over AI trade, a robust earnings season, and expectations of a Federal Reserve rate cut in September, has also contributed to VOO's success.

The ETF's lead over its competitors has widened steadily throughout 2025, fueled by heavy inflows. If the current pace holds, VOO is set for another $100 billion-plus inflow year, following a record $117 billion in 2024. This growth is a testament to the enduring appeal of passive investment strategies and the trust investors place in Vanguard's offerings.
