US spot Bitcoin ETFs lost $679 million in the week to October 9, the largest weekly total since late June. Wintermute sets two conditions for a recovery.
BTC$81,090.00-2.88%Updated 14 October 2026: Wintermute's own market update confirms the $679 million Bitcoin ETF outflow week and sets two conditions before it turns constructive, as Farside shows a further $65.4 million leaving Bitcoin funds.
US spot Bitcoin ETFs lost $679 million in the week ended October 9, the largest weekly total since late June, with $542 million leaving spot Ethereum products over the same five sessions. Wintermute carries both figures in its own market update, and Farside Investors' daily table totals $678.9 million for Bitcoin, so the two trackers agree to a rounding step. SoSoValue's count for the same week is $681.1 million.
The selling ran past the reporting week. Farside shows a net $65.4 million outflow on October 12, all of it out of BlackRock's IBIT, with every other listed US Bitcoin fund printing zero. Its running total for cumulative net inflows since launch is $57.1 billion, and its row for October 13 was still blank.
The week broke three runs at once: Bitcoin funds their first negative week since the week ended September 11, Solana funds their first since June, and Ethereum products their largest weekly withdrawal since January 2026.
Wintermute's reading is that this was plumbing rather than narrative. When ETF flows turned, it says, there was nothing underneath the market to catch the price.
"Crypto has no earnings to do that, so at these yields it rises only while new money keeps arriving"
Bitcoin opened the week of October 5 near $86,000 to $87,000, failed there for a third time on Tuesday, washed out to roughly $83,000 on Wednesday's FOMC minutes and the yield spike, bottomed near $80,400 on Thursday and recovered to the mid-$83,000s by October 12. CoinGlass put liquidations in the 24 hours around Thursday's low at $1.19 billion, about $1.06 billion of it long positions.
Redemptions clustered on two days. Investors pulled $487.07 million on Wednesday and $244.13 million on Thursday, before a $21.13 million inflow on Friday. The week ended a three-week run of inflows, and it followed $241.09 million of inflows the week before, a $922.19 million swing in demand.
October 7 carried the most weight. The 12 listed US Bitcoin ETFs lost $484.9 million that day, their largest single-day outflow since June 25, led by BlackRock's iShares Bitcoin Trust at $207.7 million, Fidelity's FBTC at $105.1 million and ARK 21Shares' ARKB at $101.7 million.
Over the full week, FBTC shed roughly $380.3 million and ARKB $207.2 million, while IBIT recorded a small net inflow of about $1.1 million. IBIT had also taken in $536.2 million across the five sessions through October 6, while the competing Bitcoin ETFs collectively lost $363.3 million.
October 12 reversed that split. The day's entire $65.4 million outflow came from IBIT, and no other fund moved. Net assets ended the reporting week at $105.84 billion.
Demand faded as the quarter turned. Daily Bitcoin ETF inflows averaged $341.7 million during the mid-September rally from $76,000 to $87,000, then fell to about $35 million per day over the five trading sessions through October 6, a drop of nearly 90%.
Bitcoin's price, not redemptions, did most of the damage to assets. Between October 5 and October 9 the category's net assets fell from $110.8 billion to $105.8 billion, and only about $591 million of that $4.9 billion decline came from withdrawals.
Ethereum ETFs lost $542.07 million, nearly four times the previous week's $138.02 million, with withdrawals recorded in all five sessions. Tuesday's $201.89 million and Wednesday's $160.77 million alone accounted for about 67% of the weekly total.
The streak reached nine consecutive sessions by October 12, with redemptions since September 29 totalling $697.2 million. The last positive inflow came on September 28, when $17.1 million entered.
The redemptions concentrated in one fund. BlackRock's iShares Ethereum Trust accounted for about $477 million, or 88%, of the week's ether ETF outflows. On October 7, ETHA alone shed $116.1 million and Grayscale's ETHE lost $25.8 million.
Cumulative net inflows since launch fell to $13.26 billion from $13.80 billion. Net assets dropped to $15.71 billion from $17.46 billion, a larger decline than the withdrawals alone, since the total also reflects ETH's price.
Ether fell 7.0% over the week, the worst of the majors. Wintermute attributed that to a second shock on top of the rates move: a researcher associated with the Ethereum Foundation urging users to migrate to new addresses.
Estimates of the category's size differ. An October 13 count puts ether ETF holdings at $15.9 billion against $13.2 billion invested, a 20% cushion over what buyers paid. A third figure of $14.48 billion would make the week's outflow about 3.7% of the category, against about 0.7% of Bitcoin funds' $100.6 billion.
US spot Solana ETFs lost $24.81 million, their largest weekly outflow since the funds launched in October 2025, and all five sessions were negative. It was their first outflow week in 14, ending a long run of weekly inflows, and money left the funds in seven of the eight October sessions.
The size stands out against the recent record. Two weeks earlier the funds drew $188.2 million, their second-biggest week to date, before inflows slowed to $2.4 million in the week ending October 2. The previous weekly outflow record was $8.9 million in the week ending February 6, so last week's exit was almost three times that.
Net assets fell 8.9% over the week, from $1.90 billion to $1.73 billion. The $24.81 million outflow explains only about $25 million of that $170 million decline; SOL's price covers the rest. SOL fell 10.25% during the trading week before posting modest gains over the weekend. Cumulative inflows slipped to $1.58 billion.
One fund drove the selling. Withdrawals from Bitwise's BSOL accounted for $20.9 million, or 84%, of all Solana ETF outflows.
XRP ETFs took in $11.31 million, extending their inflow streak to 13 weeks. Their last negative week ended July 10. Cumulative net inflows reached a record $1.80 billion, while net assets fell to $1.57 billion from $1.66 billion as XRP dropped 8.2% over the week.
That is the weakest position of the four large crypto ETF groups. On an October 13 count, XRP ETF investors have put in $1.80 billion and hold $1.55 billion, about 14% below what they paid, the only one of the four worth less than the money invested. The same count has Bitcoin ETFs at $57 billion in and $106 billion held, an 86% gain.
XRP funds also recorded zero net flow in four of eight recent October sessions, a sign of hesitation rather than exit.
The $11.31 million offset less than 1% of the $1.248 billion that left the Bitcoin, Ethereum and Solana groups.
Smaller products moved less. Zcash ETFs lost $30.7 million and Hyperliquid ETFs $9.4 million in the same week. Dogecoin ETFs recorded zero flows for seven consecutive days from October 1 to October 9, after a $551,000 exit on September 30.
Breadth was thin outside the majors. Of 66 large-cap altcoins with market values above $1 billion, only 11 finished the week higher, and the median decline was 3.7%. Uniswap fell 15.8% after gains the prior month, the most notable faller.
Capital that left liquid decentralized-finance tokens and large caps went to AI-related names, with Near Protocol the standout. Wintermute listed post-quantum signature support and a short squeeze as the cited causes and said it could not confirm either.
Bitcoin held up better than the rest of the market. Its dominance rose toward 59.5%, which Wintermute called the clearest internal signal of the week.
Rates did the damage, and the minutes did not soften it. The September 15-16 meeting raised the federal funds target range by a quarter point to 3.75% to 4%, by a 12-0 vote. The minutes, released the following Wednesday, record that most participants assessed another increase in the target range would likely be appropriate by year end, and rate cuts are not mentioned anywhere in the document.
Markets read it that way. A December hike was fully priced in after the release, and about 20% odds were priced on a hike at the end of October. The 30-year Treasury yield printed 5.64% on September 30, and the 10-year sat near 5.19% on October 13. The dollar was near an 18-month high.
Equities took the same backdrop better. The S&P 500 set a record and finished the week up 1.2%, while Bitcoin fell 3.2% and Ethereum 7.0% over the same stretch. Wintermute's explanation is that equities have earnings to grow into higher yields and crypto does not.
The next FOMC meeting is October 27-28. The minutes add that participants approached each meeting with an open mind and that decisions would depend on incoming information and the balance of risks.
Wintermute now needs two things before it turns constructive: a settling long end of the yield curve, and spot ETF flows back to net inflows. Until both arrive, its update says, Bitcoin stays "the high-beta, negative-skew expression of the equity market", and it would not chase lower-quality altcoins on anything that resembles a rally.
The desk also named the levels that would make it more cautious. A 30-year Treasury yield above 5.64%, the level it printed on September 30, would do it. So would Bitcoin continuing to bounce off $82,500 without breaking it.
Both are observable, and Bitcoin has already tested the second one. It failed at $86,000 to $87,000 three times before the washout to $80,400.
Three published counts of 2026 Bitcoin ETF net flows do not agree, and none of them reconciles the gap. Our October 3 report had it at $985 million. A page published October 8 put it at $1.2 billion. An October 12 count had Bitcoin ETFs at $494.1 million, with Solana funds at $816.8 million and XRP funds at $635.5 million.
What the pages do agree on is direction and frequency. Bitcoin ETFs have drawn a net $57.1 billion since launching in January 2024 and remain net positive for 2026 despite the latest redemptions. The funds logged outflows on 93 of 190 trading days this year, about 48%, and still ended in the black.
October has not followed that pattern. The month-to-date net outflow from US spot Bitcoin ETFs stands near $450 million by two separate counts of the daily totals.
Bitfinex places the flow-weighted average ETF cost basis at $84,318. Bitcoin's October 7 close under $83,000, its lowest in 20 days, put the average ETF position slightly underwater. A close back above $84,318 would restore that average position to profit; holding below it leaves the average buyer waiting to break even.
The selling continued past the reporting week. On October 12 the three main spot ETF groups all saw net outflows: Bitcoin $65.4 million, Ethereum $85.4 million and Solana $699,830. Bitcoin fell 2.8% over 24 hours to $81,382 around that date, and liquidations in the 24 hours through October 12 totalled $771 million, of which $685.6 million, nearly 89%, were long positions.
By October 13, at 14:00 UTC, Bitcoin traded at $83,173.84 and global crypto market capitalisation stood at $2.9 trillion, a 0.3% decline over the previous 24 hours.
The next scheduled input is the September consumer price index report on October 14 at 8:30 a.m. Eastern Time, with annual inflation expected to rise to 3.7% from 3.4% in August. Wintermute says the print will show whether energy inflation is spreading into core, which matters for the rate narrative. A cooler number would take pressure off the long end it wants to see settle; a hotter one leaves the same test in place.
Binance will close its bitcoin mining pool at 07:00 UTC on Nov. 10, along with Pool Savings and Cloud Mining. Its remaining 8.7 EH/s has to go somewhere else.
