The ARK 21Shares Bitcoin ETF (ARKB) has gained significant assets under management in its first two years, reaching $3.3 billion. This spot Bitcoin ETF provides investors exposure to the cryptocurrency, though it does not allow direct ownership of Bitcoin. The ETF charges a 0.21% annual expense ratio and tracks the CME CF Bitcoin Reference Rate. ARK CEO Cathie Wood is a long-time Bitcoin bull, and the firm forecasts a $28 trillion crypto market cap by 2030 with Bitcoin representing 70% of that figure.

Why it matters

The growing popularity of the ARK 21Shares Bitcoin ETF highlights the increasing mainstream adoption of cryptocurrencies, as investors seek regulated and accessible ways to gain exposure. However, the ETF structure differs from direct cryptocurrency ownership, with limitations around trading hours and ongoing management fees that experienced crypto investors may find less appealing.
