ARKB
ARK 21shares Bitcoin ETF (ARKB), an exchange traded product, is not registered under the Investment Company Act of 1940, as amended (“40 Act”), and therefore is not subject to the same regulations and protections as 40 Act registered ETFs and mutual funds. ARKB is subject to significant risk and heightened volatility. ARKB assets are not suitable for an investor who cannot afford the loss of the entire investment. An investment in ARKB is not a direct investment in bitcoin.
Bitcoin is the world's largest crypto asset by market capitalization, held by millions of individual investors, institutional funds, and sovereign governments across every major market.
ARKB is the ARK 21shares Bitcoin ETF, a spot bitcoin ETF you can buy and sell through the same brokerage account you already use for stocks.
ARKB objective:
The Fund seeks to track the performance of bitcoin, as measured by the performance of the FTSE Bitcoin Index (the “Pricing Benchmark”), adjusted for the Trust’s expenses and other liabilities. The Trust holds bitcoin and values its Shares daily based on the Index.
Professional custody, no self-custody required
ARKB's bitcoin is held in cold storage by three qualified custodians built specifically for digital asset safekeeping: Anchorage Digital Bank N.A., BitGo Bank & Trust, N.A., and Coinbase Custody International, Ltd. No wallet, private key, or crypto exchange account is required.
Trade through your existing brokerage account
Buy and sell ARKB the same way you would any stock or ETF. ARKB is listed on the Cboe BZX Exchange, is eligible for tax-advantaged accounts where permitted, and requires no specialist platform or exchange. The fund carries a 0.21% annual management fee with no additional charges.
Backed by 21shares, operated since day one
21shares is one of the world's largest issuers of crypto exchange-traded products, with a track record operating physically-backed ETPs across European and Swiss markets since before the US spot market existed. 21shares has served as ARKB's Sponsor and operator since the fund's launch, managing all operational, custodial, and regulatory functions.
Performance
The performance data quoted represents past performance and is no guarantee of future results. Investment return and principal value of an investment will fluctuate so that an investor’s shares, when redeemed, may be worth more or less than their original cost. Current performance may be lower or higher than the performance data quoted. Returns greater than 1 year are annualized.
Investing involves risk, including the possible loss of principal. Shares of any ETF are bought and sold at market price (not NAV) and may trade at a discount or premium to NAV. Shares are not individually redeemable from the ETF and may only be acquired or redeemed from the ETF in creation units. Brokerage commissions will reduce returns.
Effective August 27, 2026, the Trust calculates its NAV using the FTSE Bitcoin Index (the "Pricing Benchmark"). Prior to that date, the Trust used the CME CF Bitcoin Reference Rate – New York Variant. Performance, NAV and premium/discount data prior to August 27, 2026 reflect the previous benchmark and have not been restated.
Premium/Discount
The amount that the Fund’s market price is above the reported NAV is called the premium. The amount that the Fund’s market price is below the NAV is called the discount. The Premium/Discount chart shows the difference between the daily market price of the Fund’s shares and the Fund’s net asset value (“NAV”). The daily market price is calculated using the mid-point between the highest bid and the lowest offer on the listing exchange, as of the time that the Fund’s NAV is calculated (usually 4:00 pm Eastern time). The vertical axis of the chart shows the premium or discount of the Mid-Point price as a percentage of the NAV. The horizontal axis shows the number of trading days covered by the chart, and each bar in the chart demonstrates how many days the Fund traded within the given premium/discount range. The data presented in the chart and table above represent past performance and cannot be used to predict future results.
