Summary
US spot Bitcoin and Ether exchange-traded funds recorded $549 million in combined net outflows in the week ending around 18 October, according to SoSoValue data. Ether funds accounted for $320 million of the withdrawals and Bitcoin funds for $229 million. The outflow was smaller than the prior week's $1.22 billion combined redemption, but the direction held: Bitcoin funds posted a second consecutive weekly outflow and Ether funds a third.
Bitcoin ETF flows were volatile within the week. Farside Investors' daily data showed outflows of $65.4 million on Monday 12 October, an inflow of $175.7 million on Tuesday, outflows of $261.4 million on Wednesday, an inflow of $5.1 million on Thursday and outflows of $82.4 million on Friday. BlackRock's iShares Bitcoin Trust accounted for about $165 million of the category's outflow. Combined with the prior week's roughly $681 million outflow, two-week Bitcoin ETF redemptions total near $910 million.
Ether funds lost $320 million in the week, per Farside's daily tables, with net outflows on four of five sessions. For October to date, US spot Ether ETFs are down roughly $955 million, the largest monthly outflow of any month this year. Smaller products also saw redemptions: Solana ETFs lost about $26 million, Zcash $19 million, Hyperliquid $18 million, XRP $1.8 million and BNB $285,000, according to SoSoValue.
CoinShares attributed the selling to US macroeconomic data rather than crypto-specific factors. September CPI rose 0.6% month on month and 3.7% year on year, above a 3.6% consensus, with gasoline prices up 9.1% over the month accounting for roughly half the headline increase. Core inflation rose 0.3% on the month to 2.6% year on year. Bitcoin fell below $80,000 on 15 October for the first time in over a month, and $948.22 million of leveraged positions were liquidated over 24 hours across 177,440 traders, 90.6% of them long, per CoinGlass. The move took Bitcoin below the average US spot ETF holder's estimated cost basis near $82,300. Polymarket put the probability of no Federal Reserve change at the October meeting at about 75% on 15 October.
Despite the October reversal, both categories remain in net inflows for 2026, at about $259 million for Bitcoin ETFs and $610 million for Ether ETFs. Since launch in January 2024, US spot Bitcoin ETFs have drawn $57.3 billion in cumulative net inflows. October is negative by about $615 million for Bitcoin funds after opening with roughly $293 million of inflows. The key near-term indicators are whether Ether funds post a second positive day this month and whether Bitcoin funds extend their two-week redemption run into a third.
