Substantial Outflows Hit US Bitcoin ETFs, Driven by Fidelity

US Bitcoin exchange-traded funds (ETFs) experienced a major outflow of nearly 3,700 bitcoins on October 31, 2025, with Fidelity Investments leading the withdrawal. Fidelity’s ETF alone saw an outflow of over 1,480 bitcoins, contributing significantly to the overall decrease in assets under management. BlackRock and ARK Invest also reported significant outflows, impacting Bitcoin’s trading values, which plummeted to $5.17 billion and its net asset value to $143.94 billion. Analysts believe these withdrawals are linked to recent market volatility in the crypto space, potentially influencing investor sentiment towards Bitcoin investments.
