Ether ETF inflows rebound to nearly $690 million as six-day buying streak builds

U.S. spot Ether exchange-traded funds posted a strong weekly rebound, drawing roughly $690 million in net inflows after recording outflows the previous week. The shift gives ETH/USD traders a fresh institutional-flow signal at a time when crypto markets are balancing stronger demand from regulated products against a still-volatile macro backdrop.

The Block reported that spot Ether ETFs attracted $689.9 million during the week ending September 25, reversing about $140 million of net outflows in the prior week. The funds finished each trading session with positive flows, with Monday producing the largest daily total of the week. Crypto.news reported a similar weekly figure of about $689.8 million and said the products remained in positive territory across all five sessions.

Friday’s flow data reinforced the trend. KuCoin, citing SoSoValue data, reported about $86.95 million in net inflows on September 25, marking a sixth consecutive positive session. BlackRock’s ETHA led Friday’s inflows, while BlackRock’s staking-focused ETHB also attracted capital. The combined sequence suggests that demand was not confined to a single day or product.

The weekly rebound is important because ETF flows provide one of the clearest windows into how traditional-market investors are allocating to Ether. Spot products allow investors to gain regulated ETH exposure through brokerage accounts without directly managing tokens or wallets. Sustained inflows can therefore signal broader institutional participation, although they do not guarantee a directional move in ETH/USD and can reverse quickly if market conditions weaken.

The Block also reported that the Ether funds ended the week with about $17.8 billion in net assets and roughly $13.9 billion in cumulative inflows since launch. The latest weekly total was the strongest since late August, reinforcing the idea that institutional demand has recovered after the prior week’s pullback.

For ETH/USD, the immediate question is whether the positive flow streak extends into the next trading week. Continued inflows would show that investors are still increasing regulated Ether exposure, while a sharp reversal would suggest the latest rebound was more tactical than durable. Traders will also watch how ETH responds relative to Bitcoin as both assets attract renewed ETF demand.

The next set of daily ETF figures will therefore be closely watched alongside broader crypto risk sentiment, U.S. yields and regulatory developments. For now, the latest data point to a clear improvement in institutional flow momentum for Ether after a weak prior week.
