BlackRock pulled in a combined $896.5 million across its spot Bitcoin and Ethereum ETFs during the week ending August 7, a haul that underscores just how much of the current wave of institutional crypto demand is concentrating in a single issuer’s products, according to Finbold. IBIT, the firm’s Bitcoin fund, brought in $693.5 million of that total, while ETHA, its Ethereum vehicle, added $203 million.
The daily breakdown shows the buying was not evenly spread. IBIT’s strongest day was August 5, with $196.8 million in inflows, while ETHA actually posted a $9 million outflow on August 3 before swinging to inflows every day that followed, peaking at $81.1 million on August 6.
One Firm, Most of the Market
The scale of BlackRock’s haul relative to the rest of the field is striking: IBIT alone captured roughly 80% of all new capital flowing into Bitcoin ETFs that week, while ETHA accounted for more than 83% of Ethereum ETF inflows. Rivals picked up the remainder — Fidelity’s FBTC added $116.5 million and its Ethereum counterpart FETH brought in $24.2 million — but neither came close to matching BlackRock’s share.
Industry-wide, spot Bitcoin ETFs took in $865.4 million for the week, meaning BlackRock’s product alone accounted for the large majority of that total, while the broader Ethereum ETF category added $243.7 million.

Five Straight Weeks of Ether Demand
The Ethereum side of the ledger has been particularly consistent. Spot Ethereum ETFs have now logged five consecutive weeks of net inflows, pushing cumulative inflows since launch past $11.2 billion, with ETHA alone responsible for more than $5.4 billion of that figure. Some of that momentum is being reshaped by the arrival of staking-enabled products like BlackRock’s ETHB, which has grown from roughly $107 million in seed capital to more than $250 million within its first week — though a portion of that growth reflects capital rotating out of the non-staking ETHA rather than genuinely new money entering the market.
Bitcoin climbed from around $63,000 to nearly $65,000 over the week, while Ethereum advanced from about $1,850 to above $1,900, price moves that roughly tracked the pace of the combined ETF buying rather than running dramatically ahead of it.
