Institutional Bitcoin ETF Inflows Surge to $600 Million Over Two Days

U.S. spot Bitcoin ETFs now hold 721,000 BTC, valued at approximately $56.7 billion. The accumulation happened through two consecutive days of strong accumulation. U.S. spot Bitcoin ETFs pulled in $358.1 million in net inflows on April 9, led by BlackRock’s iShares Bitcoin Trust (IBIT), which captured $269.3 million. Fidelity’s Wise Origin Bitcoin Bitcoin Fund (FBTC) added $53.3 million, while Morgan Stanley’s newly launched ETF attracted $14.9 million. Other contributors included Bitwise’s BITB ($11.7 million) and ARK 21Shares’ ARKB ($4.8 million). On April 10, ETFs recorded another $240 million in net inflows, with BlackRock's IBIT leading with $137.6 million and Fidelity's FBTC adding $78 million. This surge follows a brief retreat where nearly $250 million in outflows occurred over two sessions. The rapid return of capital underscores how quickly institutions can actually rotate into crypto exposure when risk conditions improve.
