Ethereum ETFs Log Ten Straight Days of Net Inflows as Bitcoin's Streak Ends
Key Takeaways
- •Ethereum ETFs recorded net inflows for ten consecutive trading days through August 27, totaling $1.42 billion.
- •BlackRock's ETHA product accounted for roughly 72% of the total inflows at $1.02 billion.
- •Bitcoin ETFs broke their nine-day inflow streak with an approximate $202 million net outflow on August 28.
- •Ethereum ETF cumulative net inflows exceed $12 billion, compared with more than $54 billion for Bitcoin ETFs.
- •ETH traded between $2,400 and $2,500 during the streak, supported by lower Treasury yields and risk-on sentiment.
Ethereum ETFs recorded net inflows for ten consecutive trading days, from August 17 through August 27, accumulating $1.42 billion in total. The run stands as one of the more sustained institutional endorsements Ethereum has received since spot ETFs launched in July 2024. Spot ETFs gave institutions a regulated wrapper for ETH exposure without self-custody, and flow data like this has become one of the most closely watched signals of where that demand is heading.
Bitcoin funds, by contrast, saw their own nine-day inflow streak come to an end with a net outflow of roughly $202 million on August 28.
BlackRock doing the heavy lifting
BlackRock's ETHA product accounted for $1.02 billion of the total inflows over the ten-day window—roughly 72% of everything that came in. The concentration underscores how a single large issuer continues to anchor flows across both Ethereum and Bitcoin ETF complexes, a pattern that has held since the products' early months.
The strongest single day of the streak was August 27, when Ethereum ETFs logged $225.8 million in net inflows, the highest figure recorded since October 28, 2025. On that same Thursday, Bitcoin ETFs took in $242.3 million. The divergence emerged the following day, when Bitcoin flipped to outflows while Ethereum's streak remained 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, leaving Ethereum's base roughly a quarter the size of Bitcoin's even after this streak.
ETH traded 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.
Competitive dynamics
BlackRock, Fidelity, Grayscale, and Bitwise all offer 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. Whether the divergence is a one-day blip or the start of a durable rotation between the two funds complexes will show up in the daily flow reports issuers publish each trading day.
