About ARK 21Shares Bitcoin ETF
ARK 21Shares Bitcoin ETF trades as ARKB and holds bitcoin to pursue a price tracking objective. Its issuer materials identify the CME CF Bitcoin Reference Rate, New York Variant, as the reference for that objective, with expenses and other liabilities affecting the result. The fund's shares provide interests in the trust's assets through a listed security. They do not give each shareholder control of a bitcoin wallet. The product belongs to the United States exchange traded offering from 21Shares, which also issues other products with different assets, structures and ticker symbols. [issuer] [annual]
21Shares US LLC is the sponsor. The trust's annual report describes its administrator, transfer agent, cash custodian and bitcoin custodians, and explains how the sponsor controls the trust's operations. Historical materials also identify ARK Investment Management in the product's sub adviser and marketing arrangements. The names attached to those roles should be read in the document for the relevant period. A bitcoin trust needs custody, accounting and share administration even when its investment approach is passive. Those operating responsibilities are separate from making an active selection of stocks or trying to outperform bitcoin. [annual] [prospectus]
ARKB completed a three for one share split in June 2025. The sponsor's filing explains that shareholders retained the same proportional interest and that the split did not change the trust's total net asset value, objective or underlying holdings. This matters when comparing raw share counts across the split date. A larger number of shares after the event does not by itself indicate a larger economic investment. The issuer's tax reporting and exchange materials identify CUSIP 040919102; some product materials display an inconsistent number, so this page records the verified identifier and its sources.

The SEC records on this page follow the trust's verified CIK and retain each filing's original accession number. Report dates identify the accounting period; filing dates identify when the SEC received the submission. The trust is not registered under the Investment Company Act of 1940. Its financial reports and prospectus describe the trust's bitcoin exposure, operating arrangements and risks. The filing list is useful for research into those dated disclosures, and should not be treated as a statement that an institution still holds a position reported in an earlier quarter.
