U.S. spot Bitcoin ETFs post $450m outflow after Senate stalls CLARITY Act

U.S. spot BTC ETFs recorded roughly $450m of net outflows, the largest single-day redemption since late June, following the Senate's failure to advance the CLARITY Act. The combination of weaker regulatory momentum and accelerated ETF selling signals reduced near-term institutional risk appetite and can tighten liquidity at the margin, increasing volatility sensitivity across BTC and correlated crypto risk assets.
