## IVV, SPY, SPYM and VOO: money in and out, side by side

Three months to Oct 8, 2026: of 3 S&P 500 ETFs counted throughout, SPYM took in the most, $15.1bn to Oct 7.

Two bases on one page. IVV, SPY and SPYM have daily figures: IVV from iShares; SPY and SPYM from State Street. VOO has monthly figures only, from SEC Form N-PORT, which reports all of a fund’s share classes together, so VOO’s month includes the mutual fund classes of the same portfolio. VOO’s bars are months and sit beside the others’ days; its cells below print the latest month filed and no figure, and are not blank; the total column adds the daily funds only.
