Vanguard’s S&P 500 ETF Tops $1 Trillion After $1.7 Billion Inflow
SPY•Vanguard's S&P 500 ETF VOO surpassed $1 trillion in assets after a $1.7 billion inflow, becoming the first ETF to hit that level. Its 0.03% expense ratio undercuts SPDR S&P 500 ETF’s 0.09%, and VOO has attracted $69 billion so far in 2026.
1. Milestone Achievement
Vanguard’s S&P 500 ETF VOO crossed $1 trillion in assets after a $1.7 billion net inflow pushed it past the milestone. This marks VOO as the first exchange-traded fund ever to reach $1 trillion, placing it among the largest pooled investment vehicles.
2. Fee Comparison
VOO’s annual expense ratio of 0.03% is one-third that of the SPDR S&P 500 ETF’s 0.09%, giving Vanguard a clear cost advantage. BlackRock’s iShares Core S&P 500 ETF matches VOO’s fee but trails with $860 billion in assets, while SPDR’s ETF holds $785 billion.
3. Inflow Trends
VOO has drawn over $69 billion in net new money through 2026, building on more than $100 billion inflows in each of the past two years. The fund has maintained positive net flows every calendar year since its launch in 2010, reflecting strong investor preference for low-cost index exposure.
4. Industry Implications
This breakthrough underscores the maturation of the ETF industry and the shifting preference toward low-cost, broad-market wrappers. VOO’s rapid ascent challenges the long-held dominance of SPDR’s flagship ETF and signals Vanguard’s bid to become the world’s largest ETF issuer.
