Item 8.01 Other Events.

On June 2, 2025, ARK 21Shares Bitcoin ETF (the “Trust”) announced that 21Shares US LLC, the sponsor of the Trust, has approved a three (3)-for-one (1) share split (the “Share Split”) of all of the Trust’s outstanding common units of beneficial interest (the “Beneficial Interests”).

In connection with the Share Split, every one Beneficial Interest that is held by the Trust’s beneficial owners (the “Record Holders”) at the close of business on June 12, 2025 will automatically split into three Beneficial Interests after market close on June 13, 2025. The Share Split is expected to be effective at market open on June 16, 2025. Following the Share Split, the Beneficial Interests will continue to trade under the ticker symbol “ARKB” under the same CUSIP, and the total net asset value of the Trust will not change as a result of the Share Split. In addition, each Record Holder will continue to hold the same percentage of the Trust’s outstanding Beneficial Interests as held immediately prior to the Share Split, and the Share Split will not modify the rights or preferences of the Beneficial Interests. The investment objective, strategy, and underlying holdings of the Trust will remain unchanged.

A copy of the press release is furnished as Exhibit 99.1 to this Current Report on Form 8-K.
