The ARK 21Shares Bitcoin ETF (ticker: ARKB) is a passively managed ETF that holds bitcoin and tracks its price, giving retail and institutional investors direct bitcoin exposure through a regulated, exchange-listed vehicle without requiring them to buy, store, or secure bitcoin themselves. Shares trade on the Cboe BZX Exchange and are priced against the CME CF Bitcoin Reference Rate - New York Variant. The Trust is sponsored by 21Shares US, a subsidiary of 21co Holdings, and is co-branded with ARK Investment Management, which serves as sub-adviser and provides marketing support. The Trust launched in January 2024 as one of the first spot bitcoin ETFs approved in the U.S. The Trust's only revenue source is a unitary Sponsor Fee of 0.21% per year on bitcoin holdings, which accrues daily and is paid in bitcoin weekly. The Sponsor covers all ordinary operating expenses out of this fee. The Trust's revenue is driven entirely by AUM, which moves with the price of bitcoin and net investor inflows or outflows. Ordinary investors access the Trust through secondary market trading; the Trust only transacts directly with Authorized Participants, who create or redeem blocks of 5,000 shares at a time. The Trust does not lend or stake its bitcoin and uses no leverage. Beyond ARKB, 21Shares operates spot ETFs for Ethereum, Solana, XRP, Dogecoin, and Sui, and has filed for additional altcoin ETFs, positioning itself as a broad-based digital asset ETF issuer.
