Ethereum ETFs see 10 straight days of net inflows as Bitcoin streak snaps

For ten straight trading days, investors kept hitting the buy button on Ethereum ETFs. The streak, which ran from August 17 through August 27, pulled in a cumulative $1.42 billion in net inflows, marking one of the more sustained institutional endorsements Ethereum has received since spot ETFs launched in July 2024.

Bitcoin, meanwhile, had its own good run going. Then it didn’t. A net outflow of roughly $202 million on August 28 ended a nine-day inflow streak for Bitcoin funds.

BlackRock doing the heavy lifting

If you’re looking for a single explanation for Ethereum’s streak, start with BlackRock. The firm’s ETHA product accounted for $1.02 billion of the total inflows during the ten-day window, roughly 72% of everything that came in.

The streak’s strongest single day was August 27, when Ethereum ETFs logged $225.8 million in net inflows. That figure was the highest recorded since October 28, 2025. On that same Thursday, Bitcoin ETFs pulled in $242.3 million. The divergence came the next day, when Bitcoin flipped to outflows while Ethereum’s streak was still technically intact.

Where Ethereum stands in the bigger picture

Cumulative net inflows into Ethereum ETFs have now exceeded $12 billion since their July 2024 launch. Bitcoin ETFs have accumulated more than $54 billion in cumulative net inflows since inception.

ETH was trading in the $2,400 to $2,500 range during the inflow streak. Lower Treasury yields in the broader macro environment also contributed to the risk-on sentiment that benefited Ethereum inflows.

What the streak says about competitive dynamics

BlackRock, Fidelity, Grayscale, and Bitwise all have Ethereum products, and each has an interest in the asset class’s continued growth. Bitcoin’s nine-day streak ending in outflows of $202 million against a $54 billion cumulative base represents a limited impact on its overall position, but the timing—Ethereum extending a streak on the same day Bitcoin’s ended—is notable for allocators tracking relative momentum.
