U.S. spot Bitcoin and Ethereum ETFs recorded $924M and $824M in net inflows respectively during the week of August 24–28, driven primarily by BlackRock's IBIT and ETHA funds.

During the week ending August 28, U.S. spot Bitcoin ETFs absorbed $924 million in net inflows, with BlackRock's IBIT accounting for $938 million of that total. Spot Ethereum ETFs drew $824 million in the same period, though BlackRock's ETHA captured only $567 million of the inflow volume. The figures span the August 24–28 interval.
The data suggests concentration of capital among major issuers, particularly BlackRock's Bitcoin product, which exceeded the aggregate inflow figure for its asset class. The gap between ETHA's contribution and total Ethereum ETF inflows indicates participation from other providers in the space.
What remains unclear is whether the inflows reflect sustained institutional demand, tactical rebalancing, or responses to price movements during the period, and how these figures compare to historical weekly patterns in spot ETF flows.
