# VOO and IVV own the same S&P 500 stocks at the same fee

The two funds were both up 14.33% this year through Oct. 21, and the 10-year gap is not a reason to choose one or to switch.

By ETF.net Research. Published Oct 23, 2026.

Vanguard S&P 500 ETF VOO and iShares Core S&P 500 ETF IVV charge the same **0.03%**, and through Oct. 21 both were up **14.33%** this year on net asset value, the value of the fund's holdings per share.

Buy either with new cash. Do not sell the one you already own to get the other.

## Same index, same stocks

Both funds track the S&P 500, the index of large U.S. companies. [S&P Dow Jones Indices](https://www.spglobal.com/spdji/en/documents/methodologies/methodology-sp-us-indices.pdf), in its July 2026 methodology, weights that index by market value and rebalances it each quarter. Both funds track it under those rules.

[Vanguard's prospectus dated April 28](https://advisors.vanguard.com/assets/corp/fund_communications/pdf_publish/us-products/prospectuses/p968.pdf) lists the 0.03% fee. [BlackRock's prospectus dated July 31](https://www.blackrock.com/us/individual/literature/prospectus/p-ishares-trust-us-sp-cap-non-sector-3-31.pdf) lists the same 0.03% for IVV. On $100,000, the bill is $30 a year either way.

## The gap depends on the price you use

Market price is what the shares last traded for. You buy and sell at that price.

The table is the longer record [Vanguard](https://workplace.vanguard.com/investments/product-details/fund/0968) and [iShares](https://www.ishares.com/us/products/239726/ivv-ishares-core-sp-500-etf) publish on net asset value, year to date through Oct. 21 and the other lines through Sept. 30.

Table: , Vanguard S&P 500 ETF VOO, iShares Core S&P 500 ETF IVV

Each return in the table is a tie or a gap of 0.01 percentage point. The 10-year rates are 15.30% for IVV and 15.29% for VOO.

Compound those annualized rates for 10 years and $100,000 in IVV finishes $360 ahead of the same sum in VOO. On market price, both issuers print 15.30% for the same 10 years, and that lead is gone.

The S&P 500 is one index, and each issuer prints its own total return for it next to the fund. Over those 10 years [Vanguard](https://workplace.vanguard.com/investments/product-details/fund/0968) prints 15.33% and [iShares](https://www.ishares.com/us/products/239726/ivv-ishares-core-sp-500-etf) prints 15.32%.

The two readings differ by 0.01 percentage point, the same gap that separates the funds on that 10-year line.

## What is actually different

VOO is an exchange-traded share class of Vanguard 500 Index Fund, so the ETF shares and the mutual-fund classes own one portfolio, as [Vanguard's prospectus dated April 28](https://advisors.vanguard.com/assets/corp/fund_communications/pdf_publish/us-products/prospectuses/p968.pdf) sets out. On Sept. 30 the ETF shares were $1,032.3 billion of the fund's $1,732.0 billion.

IVV is a separate fund of iShares Trust, under BlackRock's iShares brand. [iShares](https://www.ishares.com/us/products/239726/ivv-ishares-core-sp-500-etf) reported $890.4 billion on Oct. 21, three weeks later, and that figure is the whole fund rather than one share class. The ETF shares alone are already larger than all of IVV, and the full Vanguard fund is larger still.

For a buyer, the cost that matters is the spread. Over the 20 sessions through Oct. 22, VOO traded $4.27 billion a day, against $3.98 billion for IVV. Vanguard's 30-day median bid-ask spread was 0.004% as of Oct. 20, and iShares reported 0.01% for IVV as of Oct. 21.

The spread is the gap between the buying price and the selling price. On a $100,000 quote, that gap is $4 for VOO and $10 for IVV. Buying at the higher price and later selling at the lower one can cost the full gap, and it is a cost of the trade, not of the years you hold.

## Buy either, and do not switch

On these numbers, neither fund is the better S&P 500 holding. What changes the practical choice is the account, not the stocks.

If you hold neither, buy either. If your broker charges a commission on only one of them, take the free trade.

If you already hold one, keep it. Selling to switch can mean a tax bill, and that 10-year lead is 0.01 percentage point on net asset value, gone on market price. That is not enough to pay a tax to capture.
