U.S. Spot Bitcoin ETFs Record $228M Net Outflow on March 6 After $1.1B Three-Day Inflow Streak

U.S. spot Bitcoin ETFs recorded a $228 million net outflow on March 6 as Bitcoin traded below $71,000, ending a three-day streak of around $1.1 billion in cumulative net inflows, ChainThink data show. iShares Bitcoin Trust saw the largest redemptions at about $890 million, followed by Fidelity Wise Origin Bitcoin Fund with roughly $480 million and Bitwise Bitcoin ETF with approximately $460 million, while overall U.S. spot Bitcoin ETFs have accumulated about $9.17 billion in net inflows this week and maintain assets under management above $90 billion. Analysts cited in the data say Bitcoin's recent move back above $73,000 is more likely a relief rally than the start of a new bull market, and some institutions earlier cautioned that Bitcoin could still retreat below $60,000 during the current crypto market correction. On the same day, Ethereum-related crypto ETFs saw around $91 million in net outflows, while XRP and Solana products posted smaller outflows of $6 million and $5 million respectively, though market data show Solana has attracted about $1.5 billion of inflows since its spot ETF debuted in July 2025.
