BONDBLOXX USD HIGH YIELD BOND TELECOM, MEDIA & TECHNOLOGY SECTOR ETF (XHYT) Exchange: NYSE ARCA

TheFund is newly organized, non-diversified and seeks to track the investment results of the ICE Diversified US Cash Pay High Yield Telecom,Media & Technology Index (the “Index”), which is a rules-based index consisting of U.S. dollar-denominated belowinvestment grade bonds (as determined by ICE Data Indices, LLC or its affiliates (collectively “Index Provider” or “IDI”))that contains issuers from the telecom, media and technology sector, including the telecommunications, technology & electronics,and media sub-sectors. Below investment grade bonds are commonly referred to as “junk bonds.” The Index is a modified marketvalue-weighted index with a cap on each issuer of 25% of the market capitalization of the Index. This means that Index constituents arecapitalization weighted, based on their current amount outstanding, and then adjusted in accordance with the index methodology detailedbelow. There is no limitto the number of issues in the Index, but as of September 30, 2021, the Index included approximately 333 constituents. The bondsincluded in the Index are publicly issued in the United States domestic market. Because the Index is reconstituted and rebalanced monthly,the components of the Index are likely to change over time. TheIndex is composed of a subset of bonds in the ICE BofA US Cash Pay High Yield Constrained Index (the “Underlying Index”).The Index components are classified into “large cap” and “small cap” categories. Their weightings are then adjustedbased on a capitalization-weighting adjustment formula. See “More Information About the Funds—Index Construction” formore information about the adjustment formula. Asof the date of this prospectus (the “Prospectus”), the bonds eligible for inclusion in the Index include U.S. dollar-denominatedhigh yield corporate bonds, currently in a coupon paying period, that are publicly issued in the U.S. domestic market, and that: (i) areissued by companies having “risk exposure” to countries (i.e., issuers that are subject to the risks of one or moreof these countries as a result of the principal country of domicile of the issuers (as determined by the Index Provider)) that are membersof the FX-G10, which include Australia, Austria, Belgium, Canada, Cyprus, Estonia, Finland, France, Germany, Greece, Ireland, Italy,Japan, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, New Zealand, Norway, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland,the U.K. and the U.S. and their respective territories; (ii) have an average rating of below investment grade (ratings from FitchRatings, Inc.

There is no upper limit onthe maturity of bonds eligible for inclusion in the Index. For more information regarding the Underlying Index, see “More InformationAbout the Funds—Underlying Index” below. BIMuses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies,the Fund does not try to “outperform” the index it tracks and does not seek temporary defensive positions when markets declineor appear overvalued. Indexingmay eliminate the chance that the Fund will substantially outperform the Index but also may reduce some of the risks of active management,such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by aiming to keep portfolio turnoverlow in comparison to actively managed investment companies. BIMuses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy thatinvolves investing in a representative sample of bonds that collectively has an investment profile similar to that of an applicable underlyingindex. The bonds selected are expected to have, in the aggregate, investment characteristics (based on factors such as market value andsector weightings), fundamental characteristics (such as return variability, duration, maturity, credit ratings and yield) and liquiditymeasures similar to those of an applicable underlying index. The Fund may or may not hold all of the bonds in the Index. Undernormal circumstances, the Fund will invest at least 80% of its net assets (plus the amount of any borrowings for investment purposes)in high-yield, below-investment grade bonds denominated in U.S. dollars of issuers in the telecom, media and technology sector, eitherdirectly or indirectly (e.g., through derivatives). Because the Index does not have a minimum percentage in the telecommunications sub-sector,technology & electronics sub-sector, or media sub-sector, the Fund also does not have a sub-sector investment minimum; however,the Fund intends to invest at least 15% of its net assets in each of the telecommunications, media and technology sub-sectors subjectto the Fund's investment objective to track the investment results of its index and the Fund's fundamental investment policy. The Fundmay also invest up to 20% of its net assets in certain futures, options and swap contracts, U.S. Treasury obligations, U.S. Governmentobligations, U.S. agency securities, securities of other registered investment companies, cash and cash equivalents, as well as in securitiesnot included in its Index, but which BIM believes will help the Fund track its Index. Anissuer is considered to be in the telecom, media and technology sector if it derives at least 50% of its revenues or profits from theownership, operation, development, construction, management, financing, leasing or sale of telecom, media and technology assets. TheFund seeks to track the investment results of the Index before fees and expenses of the Fund. TheIndex is sponsored by the Index Provider, which is independent of the Fund and BIM. The Index Provider determines the compositionand relative weightings of the bonds in the Index and publishes information regarding the market value of the Index. IndustryConcentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particularindustry or group of industries to approximately the same extent that the Index is concentrated. For purposes of this limitation, securitiesof the U.S. government (including its agencies and instrumentalities), repurchase agreements collateralized by U.S. government securities,and tax exempt securities of state or municipal governments  andtheir political subdivisions are not considered to be issued by members of any industry. As of the date of this prospectus, the Indexcurrently holds 25% or more of its assets in the media and telecommunications sub-sectors.
