The 10 biggest U.S.-listed ETFs have amassed an eye-popping $3.7 trillion in assets.   
  
At the top of the heap sits the [**Vanguard S&amp;P 500 ETF (VOO)**](/voo) with $731 billion, while at the “small” end is the still-massive [**Vanguard Total Bond Market ETF (BND)**](/bnd) at $135 billion. Together, the top 10 represent about 30% of the entire $12.3 trillion U.S. ETF market.  
  
Size isn’t the only thing they have in common. They’re cheap—really cheap. Expense ratios run as low as three basis points and top out at 20 basis points for the [**Invesco QQQ Trust (QQQ)**](/qqq). For most investors, these funds are the ultimate set-it-and-forget-it building blocks, covering huge swaths of the global financial markets.  
  
The list skews heavily toward U.S. stocks, and especially the S&amp;P 500. Between VOO, the [**iShares Core S&amp;P 500 ETF (IVV)**](/ivv), and the [**SPDR S&amp;P 500 ETF Trust (SPY)**](/spy), the three biggest ETFs track the same venerable index that captures about 85% of the U.S. market.   
For investors who prefer even broader exposure, the fourth-largest ETF, the [**Vanguard Total Stock Market ETF (VTI)**](/vti), goes further by folding in small- and mid-caps.  
  
But the top 10 aren’t entirely U.S. equity funds. At Nos. 7 and 8 are a pair of international stock funds, the [**Vanguard FTSE Developed Markets ETF (VEA)**](/vea) and the [**iShares Core MSCI EAFE ETF (IEFA)**](/iefa). BND rounds out the list at No. 10, the lone bond fund among the giants.

## Beyond Beta

While most of the ETFs in the top 10 deliver broad market exposure, three stand out for doing something different. The [**Vanguard Value ETF (VTV)**](/vtv) and the [**Vanguard Growth ETF (VUG)**](/vug) tilt the large-cap universe along factor lines. VTV toward companies trading at cheaper valuations, VUG toward those with faster earnings and sales growth.  
  
Then there’s QQQ, arguably the biggest outlier of the bunch. Tracking the Nasdaq-100, it’s the narrowest of the top 10, with roughly 60% of its weight in technology. That tilt has worked in its favor, turning QQQ into the market’s go-to tech proxy and one of the most successful ETFs of all time.
