Summary
US spot Bitcoin and Ether ETFs recorded combined net outflows of $549 million in the week ending around 18 October 2026, according to SoSoValue data reported by Altcoin Buzz. Ether funds accounted for $320 million of the total and Bitcoin funds $229 million. The outflows were smaller than the prior week's $1.22 billion combined outflow, but marked a second consecutive down week for Bitcoin funds and a third for Ether funds.
Bitcoin ETF flows were choppy during the week. Per Farside Investors' daily tables, Bitcoin funds recorded -$65.4 million on Monday 12 October, +$175.7 million on Tuesday, -$261.4 million on Wednesday, +$5.1 million on Thursday and -$82.4 million on Friday, a net outflow of about $228 million. BlackRock's iShares Bitcoin Trust accounted for about $165 million of the category's outflow. Bitcoin ETF redemptions across the two weeks total roughly $910 million, following about $681 million the prior week.
Ether funds lost $320 million in the week, per Farside's Ether table, with daily totals of -$85.4 million, +$24.8 million, -$129.5 million, -$60.3 million and -$69.7 million across 12-16 October. For October to date, US spot Ether ETFs are down roughly $955 million, the largest monthly outflow of 2026, according to the report.
Smaller fund groups followed a similar pattern. Solana ETFs lost about $26 million, Zcash $19 million, Hyperliquid $18 million, XRP $1.8 million and BNB $285,000 in the week, per SoSoValue data.
CoinShares attributed the selling to US economic 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 around 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, below the average US spot ETF holder's estimated cost basis near $82,300. Per CoinGlass, $948.22 million of leveraged positions were liquidated over 24 hours across 177,440 traders. Polymarket priced about a 75% probability of no rate change at the October Fed meeting as of 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 launching in January 2024, US spot Bitcoin ETFs have accumulated $57.3 billion in cumulative net inflows. Bitcoin funds opened October with roughly $293 million of inflows before turning negative by about $615 million for the month. The next signals to watch are whether Ether funds post a second positive day in October and whether Bitcoin funds extend redemptions into a third week.
