Company Description

ARK 21Shares Bitcoin ETF (ARKB) is an exchange-traded fund that offers investors exposure to bitcoin through a trust structure. According to its SEC filings, the fund issues common shares of beneficial interest that trade under the symbol ARKB on the Cboe BZX Exchange, Inc. The ETF structure is designed so that shares represent an interest in the bitcoin holdings of the ARK 21Shares Bitcoin ETF trust (the “Trust”).

The Trust is sponsored by 21Shares US LLC (the “Sponsor”). The Sponsor is responsible for overseeing key operational relationships, including custodial arrangements for the Trust’s bitcoin and agreements with authorized participants who create and redeem shares of the ETF. ARK 21Shares Bitcoin ETF is classified in regulatory filings under the sector "Commodity Contracts Brokers & Dealers," reflecting its focus on bitcoin as a digital commodity held on behalf of shareholders.

Custody of bitcoin holdings

The Trust’s SEC disclosures describe a multi-custodian approach to safeguarding its bitcoin. The Trust has entered into a custodial services agreement with BitGo Trust Company, Inc., a South Dakota trust company, under which BitGo establishes and maintains segregated custody accounts for the receipt, safekeeping, and maintenance of the Trust’s bitcoin holdings. This arrangement is intended to keep the Trust’s bitcoin in accounts controlled and secured by BitGo, subject to the terms of the custodial agreement.

In addition to BitGo Trust Company, Inc., the Trust’s existing custody arrangements with Coinbase Custody Trust Company, LLC, Anchorage Digital Bank N.A., and BitGo New York Trust Company, LLC remain in place. Each of these entities is identified in SEC filings as a “Custodian,” and together they are referred to as the “Custodians.” The Sponsor anticipates utilizing the custodial services of each of the Custodians for the Trust’s bitcoin, giving the Sponsor flexibility to allocate holdings across multiple regulated institutions.

Allocation among multiple custodians

The Sponsor allocates the Trust’s bitcoin among the Custodians based on several factors described in the filings. These include the concentration of the Trust’s bitcoin at each Custodian, the Sponsor’s assessment of the safety and security policies and procedures of each Custodian, the insurance policies of each Custodian, the fees and expenses associated with storage, and the fees and expenses associated with transfers to or from accounts at each Custodian. The Sponsor may also consider any other factor it deems relevant when making allocation decisions.

The Sponsor does not intend to disclose the amount or percentage of the Trust’s bitcoin held at any specific Custodian. It may change the allocation between Custodians at any time, in its sole discretion and without notice to shareholders of the Trust. According to the filings, the fees and expenses associated with the transfer of bitcoin between accounts at each Custodian are borne by the Sponsor, not by the Trust or its shareholders.

Bitcoin transfers and network considerations

Transfers of bitcoin between the accounts at each Custodian generally occur “on-chain” over the Bitcoin network. The Trust’s filings note that on-chain transactions are subject to all of the risks of the Bitcoin network, including the risk that transactions will be made erroneously and are generally irreversible. This highlights that the Trust’s operations depend on the functioning and security of the underlying Bitcoin network when moving assets between custodial accounts.

Authorized participants and share creation/redemption

ARK 21Shares Bitcoin ETF uses authorized participants to create and redeem large blocks of shares, referred to as “Baskets.” An SEC filing describes an authorized participant agreement between the Trust and Macquarie Capital (USA) Inc. (“Macquarie”), under which Macquarie acts as an authorized participant of the Trust. Under this agreement, Macquarie may place orders to create or redeem Baskets of 5,000 shares, and the agreement sets out the procedures for delivering the bitcoin required for such creation and redemption.

The agreement with Macquarie differs from the Trust’s agreements with other authorized participants in that it allows for in-kind creation and redemption orders. In connection with each order by Macquarie to create or redeem one or more Baskets, the Sponsor may charge a transaction fee, unless waived by the Sponsor. The agreement can be amended as mutually agreed by the parties, without the consent of any shareholder, and certain procedures governing the order entry system may be amended by the Trust without the consent of Macquarie or any shareholder.

Indemnification and risk allocation

The Trust’s custodial and authorized participant agreements include indemnification provisions that allocate certain risks among the parties. Under the custodial services agreement, the Trust is required to indemnify BitGo and certain of its affiliates and service providers in specified situations, including for certain losses arising from the Trust’s use of the services, breach of the agreement, or violation of applicable law. Similarly, under the authorized participant agreement, the Trust must indemnify Macquarie and certain of its affiliates in certain circumstances, including against losses related to untrue or alleged untrue statements of material fact under the Registration Statement and Prospectus, breach of the agreement, or violation of applicable law.

The custodial services agreement requires BitGo to maintain reasonable insurance policies and coverage, as described in the filing. The agreement commenced on a specified date and continues for an initial one-year term, renewing automatically for successive one-year periods unless either party provides notice of non-renewal within the timeframe set out in the agreement. The authorized participant agreement with Macquarie continues indefinitely unless terminated in accordance with its terms.

Trading venue and regulatory status

According to the Trust’s 8-K, the common shares of beneficial interest of ARK 21Shares Bitcoin ETF are registered under Section 12(b) of the Securities Exchange Act of 1934 and trade under the symbol ARKB on Cboe BZX Exchange, Inc. The Trust identifies itself as an emerging growth company under applicable SEC rules. This status can affect certain reporting and disclosure requirements, as outlined in federal securities regulations.

Through its structure as a bitcoin ETF, ARK 21Shares Bitcoin ETF provides a way for market participants to gain exposure to bitcoin through a security listed on a national securities exchange, with the operational details and risk factors described in its SEC filings. Investors and analysts can refer to these filings for more detailed information on the Trust’s agreements, risk disclosures, and operational framework.
