Overview
- Vanguard’s S&P 500 ETF, ticker VOO, has passed $1 trillion in assets, making it the first exchange-traded fund to reach that level.
- VOO’s lower fee — about 0.03% versus roughly 0.09% for the long-time leader SPY — is widely cited as the main driver of its large inflows.
- Reports disagree on exact inflow totals for 2025, with published estimates ranging from roughly $100 billion to $250 billion and some outlets citing average daily inflows near $1.25 billion.
- Because S&P 500 funds allocate new money by market value, big inflows to VOO tend to direct more capital to the largest companies and can amplify mega-cap concentration in passive portfolios.
- The milestone underscores the shift from active mutual funds to low-cost ETFs and comes as Vanguard has broadened platform access to selected cryptocurrency funds while keeping VOO’s plain S&P 500 objective unchanged.
