According to @CathieDWood, ARKB is not a direct investment in bitcoin, so holders gain price exposure without on-chain ownership and will forgo certain rights available to direct BTC holders. Source: @CathieDWood via X on Dec 8, 2025. She also states that ARKB is not registered under the Investment Company Act of 1940, highlighting a different regulatory framework versus 1940 Act mutual funds and ETFs, which is material for traders evaluating risk, protections, and operations. Source: @CathieDWood via X on Dec 8, 2025. Trading takeaway: use ARKB for brokerage-based BTC exposure while recognizing that direct BTC is required for on-chain rights and functionality, and align position sizing and risk controls with the product’s structure and regulatory status.
