iShares Core U.S. Aggregate Bond ETF
iSharesUS aggregate bondsBond fundHoldings as of May 31, 2026Source: SEC Form N-PORT

These holdings come from the fund's SEC Form N-PORT filing for May 31, 2026. Funds make a quarter-end portfolio public up to 60 days after the quarter, so this is the newest one available; weights have moved since.

Weights are percent of net assets and add up to 101.9%. That happens when a fund holds cash or collateral positions (such as a money-market sweep) alongside its securities.

This is a bond fund. Its rows are individual bonds and cash-like holdings, not company shares, so they are not linked to stock pages and there is no sector mix. The top holdings and concentration below are grouped by issuer, because one issuer is often hundreds of separate bonds.
