VOO vs IVV: Two Identical S&P 500 ETFs — Does the Provider Matter?
VOO and IVV are functionally identical: same S&P 500 index, same 0.03% TER, same physical full replication. The differences are minimal — AUM, slight liquidity differences, and provider preference. IVV launched in 2000 and has a longer track record; VOO launched in 2010 and has grown to comparable size. For practical purposes, they are interchangeable.
Key Differences
- Identical index (S&P 500), identical TER (0.03%), identical replication methodology
- IVV has the longer track record (2000 vs 2010 inception)
- Both are among the most liquid ETFs in the world with penny-wide spreads
- If your brokerage offers commission-free Vanguard ETFs, pick VOO; if iShares, pick IVV
- Tax-lot management is the only other consideration — don't switch between them unnecessarily
