IVVAiShares Core S&P 500 ETF

VOOAVanguard S&P 500 ETF

In short

IVV The 2000-vintage iShares take on the S&P 500, now a $100B-plus cornerstone holding: roughly 500 large US companies, 0.03% a year, and tracking that stays tight to the index.

VOO Not a standalone ETF but a share class of Vanguard's flagship 500 Index Fund: the same roughly 500 large US companies, 0.03% a year, in a wrapper you can trade all day.

Stated mandate

IVV The fund seeks to track the investment results of an index made up of large-capitalization U.S. equities.

VOO The fund invests in stocks represented by the S&P 500 Index and seeks to closely track that index's return as a measure of overall U.S. stock performance.

Why people hold it

IVV Costs 0.03% a year, a fraction of the typical fee among S&P 500 trackers, and undercuts the category's founding fund (SPY, 0.09%) on the same index.
Tracking is the whole job, and it does it about as tightly as this peer group gets: roughly 500 large US companies, no manager discretion bolted on.
A $100B-plus fund that trades heavily all session, which is what keeps bid-ask spreads thin for retail-sized orders and institutional blocks alike.
Running since 2000 as a registered open-end fund, with quarterly distributions and one of the longest live records in the S&P 500 aisle.ishares.com

VOO 0.03% a year against a 0.15% median for S&P 500 trackers. On a fund this size, that fee gap is the whole product.
Holds the index outright, all roughly 500 names, and its tracking record sits among the tightest in the S&P 500 group.vanguard.com
One of the most actively traded ETFs in the market, which tends to keep the cost of getting in and out small.
It is the ETF share class of Vanguard's 500 Index Fund, and Vanguard is owned by its own funds, so no outside parent takes a cut.vanguard.com sec.gov

Worth knowing

IVV Pure US large cap. No mid caps, no small caps, nothing overseas, so it works as one slab of a portfolio rather than the whole thing.
It rides the index in both directions: when the S&P 500 has an ugly year, this has the same ugly year, minus the fee.
A near-identical rival shaves a basis point (SPYM at 0.02%). On $10,000 that gap is about a dollar a year, so structure and trading habits matter more.

VOO Large US companies only, weighted by size, so the biggest few names carry the most weight and drive much of the move.spglobal.com
Membership is not purely mechanical: an S&P index committee decides which companies come in and go out.spglobal.com
SPYM tracks the same index for 0.02%. A rounding error for most, but real if cost is your only tiebreaker.
