iShares Core S&P 500 ETF (IVV) review

IVV is the iShares answer to VOO and comes close to a tie. Its fund page lists an expense ratio of 0.03% as stated in the prospectus, the S&P 500 Index as its benchmark, 505 holdings and net assets of $879,087,882,058 as of November 12, 2026. iShares describes it as a low-cost core building block for large-cap US exposure. For investors who trade, the 30-day median bid/ask spread of 0.01% is the detail to note, since it keeps the cost of buying and selling small. Distributions are paid quarterly and the fund has traded on NYSE Arca since its May 15, 2000 inception. It ranks below VOO because the two are the same price and track the same index, and Vanguard's fund is larger. As with any S&P 500 fund, you get only the largest US companies, so pair it with a small-cap or international fund if you want more breadth.
