Which Total U.S. Stock Market ETF Is Better: Vanguard or iShares?

Key Points

• iShares Core S&P Total U.S. Stock Market ETF and Vanguard Total Stock Market ETF provide nearly identical low-cost access to the broad American equity market

• Vanguard Total Stock Market ETF manages a significantly larger asset base with over $2.3 trillion in assets under management

• Both funds have delivered nearly identical total returns over the trailing five years while maintaining matching risk profiles

The Vanguard Total Stock Market ETF (NYSEMKT:VTI) and the iShares Core S&P Total U.S. Stock Market ETF (NYSEMKT:ITOT) are nearly indistinguishable in cost and performance, though the Vanguard fund manages a vastly larger asset base.

Investors looking for a single fund to capture the entire American equity market often find themselves choosing between these two industry giants. These exchange-traded funds (ETFs) allow investors to own a piece of nearly every publicly traded company in the United States, providing a diversified foundation for any long-term portfolio without the need to pick individual stocks or manage complex rebalancing strategies manually while maintaining high liquidity for easy trading.

Snapshot (cost & size)

Beta measures price volatility relative to the S&P 500; beta is calculated from five-year monthly returns. The 1-yr return represents total return over the trailing 12 months. Dividend yield is the trailing-12-month distribution yield.

Cost is a neutral factor in this matchup as both funds carry an exceptionally low 0.03% expense ratio. This ranks among the most affordable options in the industry. Dividend payouts are also closely matched, with both funds offering a 1% yield to shareholders as of June 17, 2026.

Which fund is the better buy?

For two funds seeking to represent the same thing — the totality of the U.S. stock market — the Vanguard Total Stock Market ETF and the iShares Core S&P Total U.S. Stock Market ETF do have notable differences.

The first difference is that the Vanguard fund, VTI, has nearly 1,000 more stocks in its portfolio than the iShares offering, ITOT, yet both have essentially identical performance, no matter what time frame you consider. That speaks more to the power of market-cap weighting, which significantly reduces the influence of the smallest companies, than to the funds themselves.

The second difference is the actual price, since VTI trades at a higher price than ITOT. But that probably only matters to those with limited investment capital who can’t buy fractional shares. Most people don’t face those constraints.

On a valuation basis, the Vanguard fund is currently slightly cheaper, with a forward P/E of 26.35 compared to ITOT’s 26.41. The latter’s higher ratio is likely a function of its holding fewer, higher-market-cap stocks that tend to trade at higher P/E multiples than the smallest ~1,000 stocks in VTI.

The Vanguard fund is better of the two because it is closer to fulfilling its intended task — to reflect the totality of the U.S. stock market. But as a practical matter, both funds have shown they deliver nearly identical performance and yields at the same cost. Your choice should probably be guided by whether you have easier access to one of the funds in a company-sponsored plan, like a 401(k).
