MarketsPublishedNov 2, 2026
US spot Bitcoin ETFs ended October with $515 million in net withdrawals, while Ether funds posted a record $1.61 billion in monthly outflows.
Investors pulled $643 million from US-listed spot Bitcoin exchange-traded funds (ETFs) on Friday, pushing October’s net flows into negative territory as crypto markets faced volatility following Binance’s $6.3 billion hack.
Friday’s withdrawals snapped four consecutive days of inflows, leaving the funds with $515 million in net outflows for October, their first negative month since June, according to SoSoValue. The funds still attracted approximately $361 million in net inflows for the year through October.
BlackRock’s iShares Bitcoin Trust (IBIT) led Friday’s outflows with $234 million, followed by Fidelity’s Wise Origin Bitcoin Fund (FBTC) with $201 million, according to Farside Investors data.
The withdrawals followed Bitcoin’s drop to $77,000 on Thursday. Binance, the world’s largest crypto exchange by trading volume, confirmed Friday that hackers had stolen about $6.3 billion in crypto assets.
Hardware wallet maker OneKey’s founder and CEO, Yishi, warned on X Friday that IBIT could face similar security threats because it relies heavily on Coinbase to hold its Bitcoin.
Investors also withdrew a net $156 million from US spot Ether (ETH) ETFs on Friday, bringing October’s net outflows to a record $1.61 billion. 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.
