Ark 21Shares Bitcoin ETF

Ark 21Shares Bitcoin ETF is a Delaware statutory trust that issues exchange-traded shares under the ticker ARKB and seeks to track the price performance of bitcoin, net of expenses and liabilities. The fund does not operate a traditional operating business; instead, it holds bitcoin and allows investors to gain spot bitcoin exposure through a regulated exchange-listed vehicle. Its structure relies on authorized participants, a sponsor, a trustee, custodians, and a prime broker to create and redeem shares in large baskets. The product sits within the broader 21Shares platform, which has experience launching and operating digital-asset exchange-traded products across multiple jurisdictions. The ETF’s value proposition is simple: provide market access to bitcoin without requiring investors to directly custody the asset themselves.
