U.S. spot Bitcoin exchange-traded funds recorded $282.6 million in net outflows on Thursday, their largest single-day withdrawal in nearly two months, according to SoSoValue. The reversal interrupted a powerful three-week period in which the products attracted $3.8 billion in net inflows and showed how quickly ETF demand can cool after a sustained run of buying.
Thursday marked the largest daily outflow since July 13, when $424.7 million exited the group, SoSoValue data shows. Total net assets held by U.S. spot Bitcoin ETFs stood at $97.5 billion following the session, while cumulative net inflows since the products launched reached $55.17 billion.
The scale of the latest withdrawal does not erase the substantial capital that has entered the funds over their lifetime. It does, though, place the recent $3.8 billion buying streak in a different light: a single day’s redemptions removed almost 7.5% of those three weeks of net additions.
ARK 21shares fund led Thursday’s withdrawals
ARK 21Shares’ Bitcoin ETF accounted for the largest share of Thursday’s outflows, losing $164 million, according to SoSoValue. That represented roughly 58% of the day’s total net withdrawal from the U.S. spot Bitcoin ETF category.
Grayscale’s Bitcoin Trust ETF followed with $36 million in net outflows, while Fidelity’s Wise Origin Bitcoin Fund, which trades under the ticker FBTC, posted $33.6 million in withdrawals. Together, the three funds accounted for $233.6 million of the $282.6 million total.
The concentration of flows among a small number of major products can amplify headline numbers on any given day. Yet the three-day pattern points to selling pressure extending beyond one isolated fund. Net outflows for the week had reached $449 million by Thursday, based on SoSoValue figures.
That means approximately $166.4 million had already left the group during the preceding two trading days. Thursday therefore made up the majority of the week’s withdrawal activity, rather than simply extending a steady daily decline.
Ether and Solana funds also turned negative
The selling was not limited to Bitcoin-linked products. U.S. spot Ether ETFs reported $29.8 million in net outflows on Thursday, according to SoSoValue, nearly offsetting the $34.8 million in net inflows the funds received on Wednesday.
The quick reversal in Ether ETF flows underlines how fragile short-term demand can be when buying is driven by near-term positioning rather than a long-running allocation decision. Wednesday’s inflow was modest relative to the scale of Bitcoin ETF activity, and Thursday’s withdrawal removed most of it within one session.
Spot Solana ETFs also registered net outflows, though on a far smaller scale. The products lost $483,000 on Thursday after gaining $11.7 million the previous day, SoSoValue data shows.
Solana’s figures remain small beside the Bitcoin and Ether markets, but the direction across all three asset categories was the same: funds tied to the largest digital assets saw net redemptions after receiving capital in the previous sessions or weeks.
Flow data offers a demand signal, not a complete market verdict
ETF flows are closely watched because they reveal whether money is entering or leaving regulated, exchange-traded vehicles that hold the underlying asset or seek to track its price. Net inflows generally require fund issuers and their authorized participants to create additional shares, while net outflows can lead to share redemptions and changes in the funds’ underlying asset exposure.
Daily flow figures should not be treated as a direct measure of every trader’s view of Bitcoin, Ether, or Solana. Activity in ETF shares can reflect portfolio rebalancing, profit-taking, institutional cash-management decisions, or temporary changes in risk appetite. A large outflow day can also occur after an extended period of gains without signaling a lasting break in demand.
The $55.17 billion in cumulative net inflows into U.S. spot Bitcoin ETFs provides important context. These products have absorbed substantial capital since their launch, and their $97.5 billion in combined net assets shows that Thursday’s withdrawals came from a large and established market rather than a lightly traded niche.
Even so, the latest numbers shift attention from the recent inflow streak to whether redemptions continue into the next trading sessions. A one-day withdrawal of $282.6 million would be a meaningful pullback but could remain consistent with normal volatility in a category holding nearly $100 billion in assets. Multiple large outflow days would present a clearer sign that the recent buying momentum has weakened.
Recent gains may be facing portfolio rebalancing
The timing of the withdrawals, following the spot Bitcoin ETFs’ strongest three-week inflow run of 2026, is consistent with some holders locking in gains or reducing exposure after a period of sustained demand. The available fund-flow data does not identify the traders behind those decisions or establish why they sold.
It also does not establish that money leaving Bitcoin, Ether, and Solana ETFs has shifted into XRP, Chainlink, Polkadot, cash, or any other specific destination. Asset-by-asset fund flows can move in different directions for reasons ranging from product availability to individual portfolio mandates.
For the Bitcoin ETF market, the immediate test is whether the Thursday withdrawal remains an isolated reaction after a strong three-week run or develops into a broader period of redemptions. With $449 million already withdrawn this week, the next daily flow reports will show whether the recent ETF buying cycle is pausing or merely taking a short break.
