BlackRock just pulled in 115% of all Bitcoin ETF inflows in a single day as rival funds bleed cash

BlackRock’s iShares Bitcoin Trust (IBIT) pulled in more money than the entire US Bitcoin exchange-traded fund (ETF) market gained on Aug. 27.

IBIT attracted $277.6 million during the trading session, while US spot Bitcoin ETFs collectively recorded $242.3 million in net inflows, according to Farside Investors data. That means BlackRock’s fund accounted for roughly 115% of the market’s net result.

The notable gap came from redemptions elsewhere. Fidelity’s FBTC lost $83.6 million, and Grayscale’s GBTC shed $27.2 million, producing $110.8 million of combined outflows.

Meanwhile, smaller products offset part of that pressure. Bitwise’s BITB, ARK 21Shares’ ARKB, VanEck’s HODL, MSBT and Grayscale’s lower-fee BTC fund attracted a combined $75.5 million.

Even after those inflows, every fund outside IBIT collectively finished the session with a $35.3 million net outflow.

BlackRock’s dominance extends beyond a single session

The $242 million overall inflow extended the broader Bitcoin ETF market’s positive streak to nine consecutive trading sessions while underlining how the run has depended heavily on BlackRock.

That dependence extends beyond a single session. Of the roughly $3.05 billion that US Bitcoin ETFs have attracted during their nine-day inflow streak since Aug. 17, BlackRock’s IBIT has supplied about $2.3 billion, or 75.6% of the total.
