Bitcoin ETFs record $450 million daily outflow, Fidelity leads with $214.8 million

U.S. spot Bitcoin ETFs saw a net outflow of $450.4 million on September 16, the largest single-day withdrawal since June 24. Fidelity (FBTC) led the outflows with $214.8 million, followed by BlackRock (IBIT) at $161.7 million. The market decline, which saw Bitcoin fall below $76,000, coincided with the stalling of the CLARITY Act in the U.S. Senate. While the legislative setback contributed to negative sentiment, analysts note that institutional flows remain highly sensitive to broader macroeconomic pressures and market volatility.
