BlackRock's Bitcoin ETF captures 115% of daily US inflows as rivals lose cash

BlackRock's iShares Bitcoin Trust, known as IBIT, attracted $277.6 million on Aug. 27. US spot Bitcoin ETFs recorded $242.3 million in combined net inflows during the session, according to Farside Investors data. IBIT therefore accounted for roughly 115% of the market's net result. Fidelity's FBTC recorded $83.6 million in outflows. Grayscale's GBTC recorded $27.2 million in outflows. Smaller products attracted a combined $75.5 million. Bitwise's BITB, ARK 21Shares' ARKB, VanEck's HODL, MSBT and Grayscale's lower-fee BTC fund were included in that total. Funds outside IBIT recorded a combined $35.3 million net outflow. The overall market extended its positive streak to nine consecutive trading sessions. The streak began on Aug. 17. US Bitcoin ETFs attracted roughly $3.05 billion during the streak. IBIT supplied about $2.3 billion of that amount. IBIT has recorded an inflow in every session during the streak. IBIT has accumulated about $63 billion in net inflows. IBIT manages roughly $62 billion in assets. The broader US spot Bitcoin ETF market has generated about $54.8 billion in cumulative net inflows. The broader market holds approximately $100.9 billion in assets. IBIT's cumulative inflows exceed the category total because historical redemptions from funds such as GBTC offset subscriptions into IBIT and other products. IBIT reached $50 billion in assets in roughly 11 months, making it the fastest ETF on record to reach that level. IBIT later crossed $70 billion after 341 trading days. Options on IBIT launched in November 2024. Those options have become one of the largest venues for Bitcoin options exposure. Financial advisers, registered investment advisers, hedge funds, family offices and other institutional investors typically consider liquidity, trading volume and issuer infrastructure when selecting an ETF. BlackRock oversees more than $10 trillion globally. BlackRock also maintains relationships across wealth-management and institutional platforms. Roughly three-quarters of the money entering Bitcoin ETFs over the past nine sessions went to IBIT.
