Ether ETFs post worst week since January
U.S. spot ether exchange-traded funds recorded $542.1 million in net outflows during the week ending Oct. 10, 2026, their worst weekly performance since January and the clearest signal yet that investor appetite for regulated ETH exposure is fading. The withdrawals extended the funds’ losing streak to nine consecutive trading days, with cumulative outflows reaching $697.2 million since Sept. 29.
The scale of the deterioration is difficult to overstate. Ether ETF flows were negative in every session after Sept. 28, when the products attracted a modest $17.1 million. That single positive day now looks like the end of an era rather than a pause. The nine-day run matches the June 17–30 episode as the third-longest outflow streak in the funds’ history, a distinction that points to a sustained shift in positioning rather than a one-off bout of profit-taking.
BlackRock’s iShares Ethereum Trust, ETHA, bore the brunt of the selling. The fund accounted for $506.1 million of the $697.2 million in cumulative outflows over the nine-day stretch. When a single product drives the overwhelming majority of redemptions across an entire category, the pattern typically reflects decisions by larger, more price-sensitive institutional allocators rather than diffuse retail selling. These are the holders most likely to rebalance quickly when their outlook on an asset changes.
The timing is also notable. The ether selling began one day before U.S. bitcoin ETFs ended their own nine-day, $3.1 billion inflow streak. That sequencing suggests the weakness in ETH demand preceded, and possibly foreshadowed, a broader cooling across crypto investment products.

Solana ETFs end record 14-week inflow streak
The reversal was not confined to ether. Spot Solana ETFs, which had been one of the strongest demand stories in the crypto ETF complex all year, also broke decisively lower. The funds posted outflows in all five trading sessions of the week, ending a record 14-week inflow streak and marking their longest daily outflow run since launch.
Weekly withdrawals totalled $24.8 million, roughly three times the previous record of $8.9 million set in the week ending Feb. 6. The Solana funds had not recorded a negative week since June 26, when they lost $1.8 million. Their 14-week inflow streak had surpassed a 13-week run that began at launch and ended in late January, meaning the products had essentially been in continuous accumulation mode for more than three months.
The abruptness of the turn deserves emphasis. Only two weeks earlier, the Solana products attracted a record $188.2 million in weekly inflows. To move from an all-time high in demand to an all-time high in outflows within a fortnight illustrates how quickly sentiment can change in crypto investment products, where positioning is concentrated, momentum-driven and prone to sharp reversals when the marginal buyer steps back.
What the flows say about investor demand
Flow data from ETFs is among the most transparent windows into institutional crypto sentiment available to the market. Because creations and redemptions are published daily, analysts can track in near real time whether money is moving into or out of regulated crypto exposure. On that measure, the latest readings point to broadening caution.
Ether’s prolonged withdrawals suggest weakening appetite for the second-largest cryptocurrency. A nine-day streak of the kind just recorded is not statistical noise. It indicates that a meaningful cohort of ETF holders, led by those in ETHA, has been reducing exposure consistently across nearly two full trading weeks. When outflows of this size persist, they create sustained sell pressure on the underlying asset, since authorised participants must offload ETH to meet redemptions.
Solana’s reversal carries a different but equally important message. Even one of the strongest recent areas of ETF demand is vulnerable to profit-taking, changing market expectations, or a wider reduction in risk appetite. The Solana funds’ streak was the longest in their history, and streaks of that length tend to end not with a whimper but with a decisive break. The $24.8 million weekly outflow, nearly triple the prior record, suggests the break was decisive indeed.
There is also a relative-value dimension worth watching. Ether’s outflows began before bitcoin’s inflow streak ended, which raises the question of whether investors were rotating out of ETH specifically, or whether ether was simply the first mover in a broader de-risking cycle that subsequently reached bitcoin and then Solana. The fact that all three categories have now printed negative or stalled flow data within a short window leans toward the latter interpretation: this looks like a generalised pullback in crypto exposure rather than an idiosyncratic ether story.
Market and regulatory implications
For the ETF issuers, the numbers are a commercial setback as much as a market signal. Ether products spent much of their early life struggling to match the inflow intensity of their bitcoin counterparts, and the January comparison is instructive: the week ending Oct. 10 was the worst since then, meaning the funds had enjoyed a strong intervening period that has now been interrupted. Sustained outflows pressure fee revenue, complicate the marketing narrative around ETH as institutional-grade exposure, and hand ammunition to sceptics who argue ether’s investment case is more fragile than bitcoin’s.
The Solana figures matter for a different reason. The SOL ETFs were the newest test of whether altcoin-linked funds could sustain durable institutional demand beyond the two largest cryptocurrencies. A 14-week inflow streak was powerful evidence that they could. An abrupt reversal, at record magnitude, does not invalidate that thesis, but it does show the demand base remains thinner and more momentum-dependent than the flows into the more established products. Regulators watching from the sidelines will note that altcoin ETF demand can reverse at pace, a relevant data point as the universe of approved crypto-linked funds continues to expand.
For traders, the practical implications are straightforward. Persistent ETF outflows remove a structural bid from the market. Ether has now lost that bid for nine straight sessions, and Solana for five. If the streaks extend into a second week, the pressure on spot prices is likely to build, since the marginal buyer in these assets has shifted from accumulating institutions to whatever discretionary demand remains. Conversely, a return to inflows would be read as evidence the pullback was a positioning event rather than a change in the underlying thesis.
The bottom line
The week ending Oct. 10 delivered the most negative flow picture for ether ETFs since January and the first negative week for Solana ETFs in more than three months. Ether’s $697.2 million nine-day bleed, dominated by ETHA, and Solana’s record $24.8 million weekly outflow together mark a turning point in what had been a year of expanding institutional crypto adoption through the ETF wrapper. The key question for the coming weeks is whether this is a routine cooling after an extended run of accumulation, or the start of a deeper reduction in risk appetite across crypto investment products. The sequencing, with ether leading, bitcoin following and Solana breaking last, suggests investors should watch the next several sessions of flow data closely before assuming either outcome. For now, the burden of proof has shifted to the bulls.
