IVV vs SPLG: Which Is the Better Pick in 2026?

Overview

IVV and SPLG are both passive S&P 500 tracking ETFs designed to deliver broad large-cap U.S. equity exposure with minimal fees. Both track the identical index and hold nearly identical stock weights, but they differ meaningfully in scale, age, expense ratio, and distribution yield—making them functionally interchangeable core holdings with minor operational distinctions.

How they differ

IVV is roughly 8.5 times larger by assets under management ($833B vs. $97.3B) and has been tracking the S&P 500 five years longer, reaching inception in May 2000 versus SPLG's November 2005 start. The expense ratio difference is negligible in absolute terms—IVV charges 0.03% while SPLG charges 0.02%—but SPLG's slight edge reflects its positioning as a lower-cost alternative within State Street's lineup. The most visible difference for income investors is SPLG's distribution rate of 1.18% compared to IVV's 1.07%, a 11-basis-point spread that may reflect minor timing variations in dividend capture or reinvestment methodology rather than a structural advantage. Both funds maintain a 1.0 beta and quarter distributions, confirming their tracking alignment.

Who each is best for

IVV: Fits investors seeking the deepest liquidity and longest operational history in an S&P 500 core holding, with particular appeal to those managing very large positions or requiring minimal bid-ask spreads.

SPLG: Designed for cost-conscious core equity investors who prioritize the lowest available expense ratio and can accept a smaller asset base without sacrificing liquidity or tracking integrity.

Key risks to know

• Concentration in megacap tech. Both funds carry identical index concentration risk: the S&P 500 is heavily weighted to a handful of information-technology and consumer-discretionary mega-cap stocks, meaning performance is partially driven by a narrow set of holdings rather than true diversification across 500 names.

• Equity market downside. These funds move with the broad market (beta of 1.0); in a significant U.S. equity decline, both will decline proportionally. No hedging or downside mitigation is embedded in either structure.

• Dividend reinvestment timing. The 11-basis-point spread in distribution rates may partly reflect the timing at which each fund's trustees process dividend capture and reinvestment; this can affect NAV and total return slightly quarter to quarter, though the effect is typically immaterial over multi-year horizons.

Bottom line

If you prioritize minimum expenses and highest yield, SPLG's 2-basis-point fee advantage and 1.18% distribution rate stand out; if you value maximum trading liquidity and the deepest historical track record, IVV's $833B in assets and May 2000 inception make it the established default. For most core equity allocations, the differences are negligible enough that fund selection can rest on account-level fee structures or existing fund family relationships. Past performance does not guarantee future results.
