US spot Bitcoin ETFs post $515M October outflow, first negative month since June
In brief
- US spot Bitcoin ETFs posted $515 million in October net outflows, their first negative month since June.
- Friday's $643 million in withdrawals ended four straight days of inflows.
- IBIT led Friday's outflows with $234 million, followed by FBTC at $201 million.
- Spot Ether ETFs logged a record $1.61 billion in October net outflows.
Friday flipped the month
Friday's exit snapped four consecutive days of inflows into the spot Bitcoin funds. BlackRock's iShares Bitcoin Trust (IBIT) led the withdrawals with $234 million, and Fidelity's Wise Origin Bitcoin Fund (FBTC) had the next-largest outflow at $201 million, according to Farside Investors data cited by Cointelegraph.
The withdrawals came a day after Bitcoin fell to $77,000 on Thursday.
It's not a write-off for the year, though. The spot Bitcoin funds still had about $361 million in net inflows for the year through October, per SoSoValue.
Outflows landed amid Binance volatility
Crypto markets turned volatile after Binance confirmed on Friday that hackers had stolen about $6.3 billion in crypto assets, according to Cointelegraph (which describes Binance as the world's largest crypto exchange by trading volume). LeoDex News couldn't independently verify that figure. The ETF withdrawals happened during that same stretch of volatility; this report doesn't attribute them to the hack.
OneKey founder and CEO Yishi went further in a post on X. In his view, IBIT could face similar security threats because it relies heavily on Coinbase to hold its Bitcoin. That's Yishi's opinion, not an established finding.
Ether ETFs log a record month
Spot Ether ETFs had it worse. Investors withdrew a net $156 million from the funds on Friday, bringing October's net outflows to a record $1.61 billion, according to SoSoValue. The previous monthly high was $1.42 billion in November 2025.
October's withdrawals also erased the Ether funds' net inflows for 2026, leaving them with roughly $45 million in net outflows for the year.
