MYMFDState Street My2026 Municipal Bond ETF

In short

IBMP A single rung of a muni ladder in one ticker: investment-grade bonds that all mature in 2027, tax-exempt income paid monthly along the way, and a defined end date instead of a fund that rolls on forever.

MYMF A muni fund with an expiration date. MYMF holds bonds maturing in 2026, pays monthly, then hands back remaining principal on or about December 15, 2026. And a manager picks the bonds, not an index.

Stated mandate

IBMP The fund seeks to track an index of investment-grade municipal bonds maturing in 2027. It is designed to provide tax-exempt income, support bond-ladder construction, and manage interest-rate risk through a defined maturity.

MYMF The fund is an actively managed target-maturity municipal bond strategy focused primarily on bonds maturing in 2026. It is designed to distribute remaining principal and liquidate around December 15, 2026.

Why people hold it

IBMP Built to act like a bond, not a bond fund: the portfolio matures in 2027 and the whole design points at that date, which is what makes ladder-building possible with one trade.ishares.com
0.10% a year, right at the typical target-maturity bond fund, and it tracks an AMT-free index, so the tax-exempt income isn't pulled back in by the alternative minimum tax.
Roughly 1,800 municipal bonds, so no single issuer carries the fund. That spread is hard to replicate buying individual munis one CUSIP at a time.
Income lands monthly, and this 2027 rung has been running since 2019, so it isn't a fresh launch built for the moment.

MYMF Maturity is written into the product: the fund is designed to distribute any remaining principal and liquidate on or about December 15, 2026.ssga.com
Actively managed in a corner of the market built on index ladders: top-down risk positioning plus bottom-up research on sectors and issuers.ssga.com
Monthly payouts from a compact book of roughly 70 munis, with income the fund seeks to keep exempt from regular federal income taxes.ssga.com
One rung in State Street's MyIncome suite, a family of target-maturity funds meant to be stacked into a custom bond ladder.ssga.com

Worth knowing

IBMP The 0.10% fee is the category median, not a discount. Treasury and corporate rungs like IBTJ (0.07%) and VBCB (0.08%) cost less, though neither pays tax-exempt muni income.
The tax exemption is the entire pitch, and it does no work inside an IRA or 401(k), where the income is already sheltered.
Trading is moderate rather than heavy, so order size and timing matter more here than in the most heavily traded bond ETFs.

MYMF Costs 0.20% a year: above the 0.18% cohort median and double the 0.10% on iBonds muni rungs like IBMO, which also targets a 2026 maturity.
A small, thinly traded fund, the setup where bid/ask spreads tend to run wider than in the category's largest names.
Launched in 2024 and built to wind up in 2026, so both the track record and the remaining life are short by design.
