IVV vs SPY vs VOO: Which Is the Better Pick in 2026?

Overview

All three track the S&P 500 Index and hold identical underlying stocks. The only meaningful differences among them are expense ratio (SPY runs 0.10%, while IVV and VOO both charge 0.03%), AUM scale, and distribution yield (IVV at 1.07%, VOO at 1.15%, SPY at 1.02%). Performance will be nearly identical before fees; over decades, the fee gap compounds.

How they differ

SPY costs three times as much to own (0.10% expense ratio versus 0.03% for IVV and VOO), which will drag returns by roughly 7 basis points annually. VOO has the largest AUM at $1,033B and the highest distribution rate at 1.15%; IVV is a close second at $833B with 1.07% yield. SPY is the oldest (inception January 1993) and was the dominant S&P 500 vehicle for decades, while VOO launched in 2010 but has since grown to be the largest. The price per share differs only because they've compounded differently since inception—economically meaningless, but relevant if you're reinvesting dividends or using fractional shares. All three carry a beta of 1.0 and rebalance quarterly.

Who each is best for

IVV: Fits investors who want S&P 500 exposure with a low fee and don't have a strong preference among the three dominant players; appeals to those building core allocations in non-Vanguard brokerage accounts where VOO may not be the default offering.

SPY: Designed for investors who prioritize liquidity and tight bid-ask spreads—SPY has the tightest intraday trading activity among the three—or who are comfortable paying a higher fee for brand recognition and decades of market history.

VOO: Matches investors seeking the largest asset base and fractionally higher dividend yield, particularly those in Vanguard-centric accounts or who value the issuer's investor-owned structure and ecosystem of low-cost funds.

Key risks to know

• Fee drag over long horizons. SPY's 0.10% expense ratio compounds to roughly 7 basis points of annual underperformance versus IVV or VOO over 20+ years, which is material for buy-and-hold investors but immaterial for frequent traders.

• Concentration in a single index. All three replicate the S&P 500, which means they carry the index's inherent concentration in mega-cap technology and financial stocks; a sharp drawdown in those sectors will hit all three equally.

• Dividend reinvestment timing. Quarterly distributions at different prices create reinvestment variance; investors using automatic reinvestment will see slightly different share accumulation depending on which fund they own and when dividends are paid.

• Liquidity and trading cost asymmetry. While all three are highly liquid, SPY's tightest spreads favor active traders, whereas IVV and VOO's marginally wider spreads are negligible for buy-and-hold investors making infrequent trades.

Bottom line

All three deliver the same S&P 500 exposure. If you're building a long-term core position and minimizing lifetime fees, IVV and VOO are economically equivalent—the choice between them hinges on account custodian defaults or Vanguard loyalty. SPY's higher expense ratio is the clearest cost drag, though its superior intraday liquidity benefits frequent traders. Past performance doesn't predict future results; performance differences going forward will track fee differentials almost exactly.
