what's ark 21shares?
ARK 21Shares is a joint venture between ARK Invest and 21Shares focused on providing regulated access to Bitcoin through exchange-traded funds (ETFs). The flagship product, the ARK 21Shares Bitcoin ETF (ARKB), tracks the performance of Bitcoin using the CME CF Bitcoin Reference Rate - New York Variant, adjusted for expenses and liabilities. It enables investors to gain exposure to Bitcoin, the largest cryptocurrency by market cap, without the complexities of direct ownership, custody, or storage. The ETF holds actual Bitcoin and is traded on the Cboe BZX Exchange, offering simplicity, liquidity, and institutional-grade security. ARK 21Shares emphasizes low fees, with an initial waiver and a competitive 0.21% expense ratio thereafter, catering to both retail and institutional investors. This partnership combines ARK's innovation research with 21Shares' expertise in crypto ETPs to bridge traditional finance and digital assets.
