▣About ARK 21Shares

ARK 21Shares is the joint ETF partnership between ARK Invest (led by Cathie Wood) and 21Shares (now a FalconX subsidiary). The partnership is best known for the ARK 21Shares Bitcoin ETF (ARKB), a physically-backed spot Bitcoin ETF launched January 2024 that tracks the CME CF Bitcoin Reference Rate. ARKB is one of the largest spot Bitcoin ETFs in the US with over $5 billion in assets. 21Shares was acquired by FalconX in November 2025, though the ARK 21Shares product partnership continues under the existing co-advisory structure with ARK Investment Management as sub-adviser.
