Prediction: Vanguard's S&P 500 ETF Will Be Back Above $1 Trillion in Assets Before the Year Is Out. Here's the Math.

Vanguard's S&P 500 ETF (VOO) briefly became the first ETF to reach $1 trillion in assets in June 2026 but has since fallen to $979 billion. The article predicts it will return above $1 trillion by year-end, requiring only a 2% gain. This prediction is supported by strong monthly inflows of approximately $14 billion and modest market gains, though concentration risk in mega-cap growth stocks poses a potential headwind.
