Ethereum ETFs pulled in $1.42 billion over ten straight trading days through August 27, even as Bitcoin funds snapped a nine-day streak with an outflow the next day. Whale wallets and BlackRock's ETHA fund added further buying on top of the ETF haul, while exchange supply keeps shrinking.
Ethereum exchange-traded funds pulled in $1.42 billion in net inflows across ten straight trading days between August 17 and August 27. Bitcoin funds were on their own run at the same time, but that ended when Bitcoin ETFs logged a $202 million outflow on August 28, closing out a nine-day inflow streak.
BlackRock leads the Ethereum haul
BlackRock's ETHA fund accounted for $1.02 billion of the ten-day total, roughly 72% of everything that came in. The strongest single day was August 27, when Ethereum ETFs took in $225.8 million — the highest figure since October 28, 2025. Bitcoin ETFs still pulled in $242.3 million that same Thursday before flipping to outflows the next day.
Ethereum ETFs have now taken in more than $12 billion cumulatively since their July 2024 launch, against more than $54 billion for Bitcoin funds since inception. ETH traded in the $2,400 to $2,500 range through the streak, and lower Treasury yields added to the risk-on mood that helped the inflows along.
Whales and BlackRock add to the demand
The ETF buying isn't happening alone. A whale wallet spent $13.55 million to buy 5,425 ETH around $2,498. A separate address received 40,000 ETH worth $100.09 million from Binance. Over the same eight trading days, BlackRock's ETHA fund saw $889.8 million in net purchases, with buying recorded on every single day. Together, that's close to $1 billion in visible ETH demand.
Meanwhile, ETH reserves across exchanges have fallen to 14.93 million ETH, continuing a decline that has run for most of the year. As buyers step in while the available supply shrinks, the market tends to grow more sensitive to further demand.
Spot buying leads, leverage stays contained
The Coinbase Premium Index has turned positive near 0.029, pointing to stronger buying from US-based exchanges after months in negative territory. Open interest sits near $14.5 billion, well below its earlier 2026 highs, suggesting the current buying is spot-led rather than driven by leverage. Whether that balance holds may depend on whether open interest starts rising faster than price.
