IBDTAiShares iBonds Dec 2028 Term Corporate ETF

IBDXBiShares iBonds Dec 2032 Term Corporate ETF

In short

IBDT Acts more like a bond than a bond fund: roughly 700 investment-grade corporate bonds that all mature in 2028, wrapped in one ticker with a defined end date. Built for ladder rungs, monthly distributions and a known finish line.

IBDX A bond fund with an expiration date. IBDX holds investment-grade corporate bonds maturing in 2032, then winds up around December 15, 2032 and pays out what's left. Bond-ladder plumbing in one ticker.

Stated mandate

IBDT The fund seeks to track an index of investment-grade corporate bonds maturing in 2028 and is designed to support income generation, bond-ladder construction, and interest-rate-risk management through a defined maturity.

IBDX The Fund seeks to track an index of U.S. dollar-denominated, investment-grade corporate bonds maturing in 2032. It is a term fund scheduled to liquidate around December 15, 2032.

Why people hold it

IBDT The defined 2028 maturity does the work: one ticker behaves like a ladder rung, no hunting down individual bonds or tracking each one's maturity.ishares.com
About 700 investment-grade corporate bonds inside, so no single issuer carries the outcome the way it would in a handful of hand-picked bonds.
Costs 0.10% a year, right at the typical fee for target-maturity bond funds, and it is one of the more actively traded names in that group.
Launched in 2018 and now a multi-billion-dollar fund, it ranks among the strongest implementations in the target-maturity bond group.

IBDX Bonds mature; most bond funds never do. This one is scheduled to liquidate around December 15, 2032 and distribute remaining assets, so the end date is written into the prospectus.ishares.com
Costs 0.10% a year, level with the target-maturity median and with BulletShares rivals BSCT and BSCU.
About 400 investment-grade corporate bonds, so no single issuer carries the fund, and cash goes out monthly instead of twice a year.
Follows the Bloomberg December 2032 Maturity Corporate Index closely and ranks in the top quartile of a crowded target-maturity field.

Worth knowing

IBDT Vanguard's VBCB targets the same 2028 corporate maturity for 0.08%, two basis points cheaper.
This is corporate credit, not Treasuries. The bonds are investment grade, but downgrades and defaults are still part of the picture.
It has a finish line. When the 2028 term ends the strategy is over, so the what-next decision lands back with you.ishares.com

IBDX Corporate credit, not government paper. Issuers can be downgraded or miss payments; the Treasury-only sibling IBTJ takes that risk off the table at 0.07%.
The maturity date is not a promised par payment. The final distribution reflects what the underlying bonds return, and monthly income moves with the portfolio.
As 2032 approaches the portfolio shortens toward cash, so rate sensitivity and income both wind down late in the term.ishares.com
