On June 2, 2026, Vanguard's S&P 500 ETF, VOO, achieved a historic milestone by becoming the first ETF ever to surpass $1 trillion in assets under management (AUM). This achievement was driven by its low expense ratio of 0.03%, which is considerably lower than competitors like SPY (0.09%), and its high average daily trading volume of approximately 9 million shares. The fund also saw significant capital inflows, receiving over $69 billion in 2026, following $118 billion in 2024 and $138 billion in 2025. This milestone reflects a broader trend in the financial markets, with global ETF AUM tripling to $21.9 trillion by April 2026 from $6.4 trillion at the start of 2020. Competitors IVV and SPY also hold substantial assets, with $859.5 billion and $784.63 billion, respectively. Goldman Sachs has set a year-end 2026 price target of 8,000 for the S&P 500, with EPS estimates of $340 for 2026 and $385 for 2027, suggesting continued demand for S&P 500 ETFs.
