Bitcoin ETF Outflows Hit $390 Million Amid Weakening Market Momentum

Bitcoin ETF outflows have reached their largest weekly total since June, with spot Bitcoin exchange-traded funds (ETFs) experiencing $389.7 million in net withdrawals during the week of August 10.

Fidelity's FBTC led redemptions at $153.2 million, followed by GBTC and IBIT at $88.3 million and $78.9 million respectively. Only two funds recorded inflows: Grayscale Mini BTC with $76.0 million and MSBT with $7.1 million.

The outflows are a reversal of the strong start to August, when spot Bitcoin ETFs experienced their strongest weekly inflow since April amid concerns over digital asset security.

Tudor Investment increased its stake in BlackRock Bitcoin ETF (IBIT) by 18.9% during Q2 2026, but analysts warn that these actions do not necessarily indicate a shift in market conviction.
