The Vanguard S&P 500 ETF slipped below $1 trillion in assets after crossing the threshold in early June, and now sits about $21 billion short. Motley Fool analyst Daniel Sparks argues the fund's steady inflows and the index's own moves make a return above the mark likely before year-end.
The Vanguard S&P 500 ETF (VOO) became the first exchange-traded fund in history to cross $1 trillion in assets in early June. The market then pulled back, and as of Friday's close the fund held about $979 billion, with shares at $686.65.
A $21 billion gap and two forces closing it
Even after a two-day rally to close out July, the fund sits roughly $21 billion short of the $1 trillion line, a gap of about 2%. Two forces have pushed toward closing it all year.
The first is new money. Investors poured about $69 billion into the fund in the first five months of 2026, nearly $14 billion a month. At that pace, inflows alone could close the gap in under two months, even if the S&P 500 goes nowhere.
Market moves are the second force. Every 1% move in the S&P 500 shifts the fund's assets by close to $10 billion, so a 2% rally could cover the whole distance in one stroke. For the prediction to fail, the index would need to fall meaningfully and stay down for the remaining five months of the year, deep enough to overwhelm nearly $14 billion a month of new inflows.
Low cost keeps the money coming
Yield isn't the draw here — the fund pays about 1.1%, unremarkable for a dividend payer. The pull is cost: it charges an expense ratio of 0.03%, so an investor with $100,000 in it pays about $30 a year. Scale and Vanguard's brand have made it the default choice for a large share of money moving into index funds.
Since its September 2010 launch, the fund has compounded at about 15% annually, a stretch capped by the AI boom that shouldn't be extrapolated forward. At $1 trillion in assets, the 0.03% fee would produce only about $300 million a year in fee revenue for Vanguard.
More than a third of the fund's assets sit in its 10 largest holdings, and Nvidia alone accounts for 7.5%. A slump concentrated in the market's biggest growth stocks would drag the fund down disproportionately and push the $1 trillion date out with it.
