BlackRock Crypto ETFs Drew $343M in Five-Day Inflow Streak

BlackRock crypto ETF inflows approached $350 million during five trading sessions as demand returned for regulated Bitcoin and Ethereum products. The asset manager's three major crypto funds attracted a combined $343.4 million from July 13 through July 17.

The total included $204.1 million for the iShares Bitcoin Trust, known as IBIT. BlackRock's Ethereum funds, ETHA and ETHB, received another $139.3 million. The activity followed several weeks of unstable flows across the wider digital asset ETF market.

IBIT started the week with a $185.5 million withdrawal on July 13. That loss placed the fund under pressure as all U.S. spot Bitcoin ETFs recorded a combined $424.7 million daily outflow.

Demand shifted during the following session. IBIT gained $138.9 million on July 14, followed by $80.8 million on July 15. It then collected $33.4 million on July 16 and $136.5 million on July 17.

Those four sessions produced $389.6 million in gross inflows. They erased the opening redemption and left IBIT with $204.1 million in net weekly additions. Farside Investors' data also shows IBIT supplied the largest Bitcoin ETF inflow on the final trading day.

The figures describe capital entering the ETF rather than a direct BlackRock Bitcoin purchase. Authorized participants create new fund shares as demand rises, while the trust adjusts its Bitcoin holdings to support those shares.

Bitcoin ETF inflows also recovered across the wider market. U.S. funds posted positive totals during each session from July 14 through July 17 after the sharp Monday withdrawal.

Ethereum ETF demand added another source of growth for BlackRock. ETHA received $58.3 million on July 14 before adding $45.3 million the next day.

ETHB attracted $4 million on July 15. ETHA later recorded $31.7 million on July 17, bringing its five-day total to $135.3 million. The two funds therefore collected a combined $139.3 million.

BlackRock crypto ETF inflows were especially concentrated in ETHA during the final session. The fund supplied $31.7 million of the $36.7 million entering all U.S. Ethereum ETFs that day. Historical inflows into ETHA have reached about $11.3 billion.

ETHB gives brokerage investors exposure to Ethereum and staking rewards, while ETHA offers spot Ethereum exposure without direct wallet management.

The ETF activity arrived as BlackRock reported record assets under management of $15.3 trillion. The company collected $192 billion in net inflows during the second quarter and $321 billion during the first half of 2026. ETFs, private markets, and fixed-income products supported those results.

BlackRock's iShares business collected $178 billion during the quarter. Total companywide net inflows reached $868 billion over the previous 12 months, showing that crypto products represent a small but expanding part of its broader ETF operation.
