Ether ETFs post worst week since January as outflow streak hits nine sessions
U.S. spot ether ETFs bled $542.1 million in net outflows during the week ending October 10, 2026, their worst weekly performance since January and the clearest signal yet that institutional appetite for the second-largest cryptocurrency has cooled. The redemptions extended a losing streak to nine consecutive trading days, with cumulative outflows of $697.2 million since the run began on September 29, according to SoSoValue data analysed by The Block.
The scale of the withdrawal is difficult to dismiss. Nine straight sessions of net redemptions is not a one-day rebalancing or a single large investor trimming a position. It is a sustained pattern, and the weekly figure, the heaviest in months, suggests that whatever prompted the first redemptions in late September has not abated. Ether products that had attracted steady demand through much of the year are now seeing holders head for the exits in size.
The timing matters for the broader market. Ether ETFs have been one of the principal conduits through which traditional finance has gained exposure to crypto since their approval. When flows reverse this sharply, the effect is felt well beyond the ETF wrappers themselves, in spot liquidity, in options positioning, and in the confidence of allocators who watch these products as a proxy for institutional sentiment.
Solana funds end record 14-week inflow run with worst week since launch
The more striking reversal of the week, however, belonged to Solana. Spot SOL ETFs recorded $24.8 million in weekly outflows, their largest since the products launched in late October 2025. The funds saw withdrawals in all five trading sessions, producing the longest daily outflow streak on record for the category.
The reversal ended a record 14-week inflow run, which had been the longest streak since the products’ inception and had surpassed a previous 13-week run that began at launch and ended in late January. For nearly a full quarter, Solana funds had been a rare pocket of persistent institutional demand, absorbing capital week after week while other categories wobbled. That narrative is now on hold.
Bitwise’s BSOL, the largest Solana fund, accounted for $20.9 million of the weekly withdrawals, roughly 84% of the category’s total, despite holding approximately $1.20 billion in net assets. The concentration is notable. This was not a broad-based retreat across every Solana product in equal measure; it was driven overwhelmingly by redemptions from the single largest fund in the category.
Against a $1.20 billion asset base, a $20.9 million weekly outflow is not an existential event. It represents a small fraction of the fund’s assets. But the direction of travel is what concerns market watchers. The largest fund in a young category setting a record for weekly outflows, on the same week the category’s longest inflow streak dies, is the kind of inflection that traders watch closely.
Bitcoin funds lose momentum as caution spreads across crypto ETF categories
Bitcoin funds were not spared. The week ended a three-week inflow streak for the category, according to the report, although the available data does not specify the weekly outflow total. The direction, if not the magnitude, is clear: the short-term inflow trend that had supported the market’s largest crypto asset has broken.
Taken together, the three categories tell a consistent story. Ether suffered its heaviest weekly redemptions in months. Solana’s previously relentless institutional demand abruptly reversed. Bitcoin’s brief inflow run stalled. These are not isolated data points pointing in different directions. They are simultaneous deteriorations across the major crypto ETF categories, and that simultaneity is the story.
When outflows are confined to one asset, analysts can usually find an idiosyncratic explanation: a network upgrade, a regulatory headline, a single large redemption. When ether, Solana and bitcoin products all weaken in the same week, the more plausible read is a macro one. Investors appear to be shifting toward caution or profit-taking across crypto investment products as a class, rather than continuing the broad-based buying that characterised much of the year.
The numbers themselves are drawn from SoSoValue data and analysed by The Block, and they cover the week ending October 10, 2026. For readers tracking the wider picture of institutional flows, our Bitcoin coverage follows the ETF flow data as it develops.
What the flow reversal means for the market
The first implication is about sentiment. ETF flows have become the market’s most-watched barometer of institutional conviction since the spot products launched. Nine consecutive days of ether outflows, a record weekly outflow for Solana funds, and a broken bitcoin inflow streak together suggest that conviction is thinning. Whether the driver is profit-taking after a strong run, macro risk aversion, or positioning ahead of perceived uncertainty, the effect is the same: the marginal institutional buyer has stepped back.
The second implication concerns the mechanics of the products themselves. ETF creations and redemptions translate directly into purchases and sales of the underlying assets. A $697.2 million cumulative outflow from ether products over nine sessions represents real selling pressure on ETH, and while $24.8 million is a modest figure for Solana, it carries outsized symbolic weight for a category whose entire investment case has rested on uninterrupted institutional adoption since launch.
The third implication is about what comes next. Streaks of this kind rarely resolve neatly. If the ether outflow run extends into a second week, the comparison to January’s lows will sharpen, and attention will turn to whether the January trough marked a floor that still holds. For Solana, the question is whether the 14-week inflow era was the anomaly or the new baseline; the first week of outflows cannot answer that, but the second and third weeks will. For bitcoin, whose weekly outflow total is not yet specified in the available data, the test is whether the three-week inflow streak was merely paused or genuinely ended.
Closing analysis
The week ending October 10 was defined by breadth of weakness rather than depth in any single category. Ether’s $542.1 million weekly outflow was the headline number, but the simultaneous reversal in Solana funds and the stall in bitcoin’s inflow trend point to something more systemic than an ether-specific problem. The 84% concentration of Solana outflows in Bitwise’s BSOL adds a wrinkle: this may partly reflect a single large holder’s decision rather than a category-wide verdict, though the fact that all five trading sessions were negative suggests broader participation.
For now, the burden of proof sits with the bulls. The crypto ETF complex has spent much of the past year demonstrating that institutional demand is durable through volatility. The week’s data does not refute that thesis, but it does test it. If flows recover quickly, this will read as profit-taking within an intact uptrend. If the streaks extend, the market will have to reckon with the possibility that the marginal institutional buyer, the force that has anchored crypto’s institutional era, has moved to the sidelines. The next set of weekly figures will be the tell.
