BlackRock inflows push U.S. spot Bitcoin ETFs $1.69B in 5 days

U.S. spot Bitcoin ETF (exchange-traded funds) recorded a fifth consecutive day of net inflows on Wednesday, bringing combined gains to $1.69 billion over the five-day stretch, according to SoSoValue. The data show a net $46.3 million flowed into the funds on Wednesday. BlackRock’s IBIT attracted $134.6 million, offsetting net outflows from Fidelity’s FBTC and three other spot Bitcoin funds.

The five-day inflows of $1.69 billion follow four prior days of positive flows and put the group of spot Bitcoin ETFs on track to report a sixth consecutive week of net inflows; that would be the longest weekly streak since July 2025, SoSoValue data indicate.

The inflow streak coincided with a broader rise in cryptocurrency prices. Bitcoin traded near $62,000 in February and has traded around $81,000 to $82,000 in recent weeks, an increase of about 26% over the past three months.

Spot Ethereum ETFs posted a fourth straight day of net inflows. Those products drew $11.6 million on Wednesday and totaled $271.6 million over the four-day period, according to SoSoValue.

Spot ETFs buy and hold the underlying asset to back shares. Because those funds take physical delivery of bitcoin or ether, fund-level inflows generally translate into purchases of the underlying cryptocurrency.

Nick Ruck, director of LVRG Research, observed that the inflow streak reflects increased institutional interest in bitcoin as a long-term allocation.

The data cover daily and multi-day flows across the major U.S. spot crypto ETF products.
