• $VOO crossed $1 trillion in AUM on June 2, 2026, becoming the first ETF in history to reach this milestone.
  
• A 0.03% expense ratio and daily trading volume of 9 million shares helped $VOO outpace both $IVV and $SPY.
  
• Global ETF AUM hit $21.9 trillion in April 2026, more than tripling from $6.4 trillion recorded at the start of 2020.

On June 2, 2026, $VOO became the first ETF ever to hit $1 trillion in ETFs AUM, according to Vanguard that they made the milestone. 

Despite being first to $1 trillion AUM, $IVV and $SPY ($859.5B and $784.63B) are still far behind at approximately 14% less than $VOO’s value. 

This historic moment is indicative of evolving perceptions about low-cost index based market exposure amongst investors.

What Pushed $VOO Past the $1 Trillion Mark

$VOO‘s cost structure has been a major driver behind its record asset growth. The fund charges an expense ratio of just 0.03%, significantly lower than $SPY’s 0.09% fee. 

That pricing difference has consistently drawn investors seeking affordable access to U.S. equity markets.

Trading activity has also worked in $VOO’s favor. The average daily volume for this fund is around 9 million shares, whereas $IVV has an average of about 8 million shares traded daily. 

The higher the average daily volume, the smaller the bid/ask spread, and therefore the lower the cost‌ of doing business over time.

The fact that $VOO has a lower price per share than $IVV compounded the difference in the number of investors that can invest in each fund. 

As of June 3, 2026, $VOO was trading at $693.36 compared to $IVV at $757.25, which made it much easier for smaller retail investors without much capital to invest in a fund like $VOO.

According to the Kobeissi Letter, $VOO received over $69 billion in capital inflows in the year 2026, with total capital inflows received by $VOO totaling $118 billion and $138 billion in 2024 and 2025, respectively, indicating that at least for the past three years, $VOO has had extremely stable momentum.

$VOO’s Milestone Reflects a Broader ETF Market Surge

The $1 trillion crossing is not just a $VOO story, it reflects a wider shift in how money moves through financial markets. 

Global ETF AUM reached $21.9 trillion at the end of April 2026, more than three times the $6.4 trillion recorded at the start of 2020.

Since the 2022 bear market, $VOO’s AUM has more than tripled. The broader ETF industry has also recorded 83 consecutive months of net inflows, a figure that points to deeply rooted investor demand.

Both the $IVV and $SPY ETFs are well positioned to reach a total AUM of $1 trillion in the near future, as both have benefited from an elevated performance of the S&P 500, which grew by approximately 10.4% in 2026. 

The above-mentioned growth in performance has contributed to the overall growth of asset bases among the three mentioned funds.

Goldman Sachs revised its S&P 500 price target for year-end 2026 to 8,000, indicating approximately a 6% return at current levels. 

Additionally, their estimate for 2026 and 2027’s EPS is $340 and $385, respectively; hence, these estimates will be a factor in keeping S&P 500 ETF funds such as $VOO in high demand for the remainder of the calendar year.
