BlackRock led the outflows as U.S.-listed Bitcoin and Ethereum exchange-traded funds shed a combined $646 million on October 7, with more than $200 million pulled from its iShares Bitcoin Trust in a single day.

The regime dashboard holds Stress at high, with breadth showing only one gainer out of 244 tracked assets. Funding rates are deeply negative, and liquidations top $138 million. Dispersion is scattered and volatility regime reads low despite the damage.

That cross-market stress suggests these outflows were not just about BlackRock or one ETF. Spot Bitcoin and Ethereum ETFs both posted major redemptions, with BlackRock taking the largest single drawdown while other major issuers were also hit. Bitcoin ETF selling was not isolated to BlackRock either, with notable October 7 outflows from Fidelity, Ark and Grayscale. Institutions were pulling exposure across the spot ETF complex during the selloff, treating the move as a broader risk-off exit rather than a problem tied to one fund.
