Investors withdrew $643.33 million from US spot Bitcoin ETFs on October 30, according to SoSoValue data. The outflow occurred one day after hackers drained approximately $6.3 billion from Binance, the world’s largest cryptocurrency exchange.
These exchange-traded funds allow brokerage customers to own Bitcoin similarly to holding a stock. The funds currently hold $98.14 billion in assets. Friday’s withdrawal interrupted a four-day streak of net inflows.
BlackRock and Fidelity Lead Exits
BlackRock’s iShares Bitcoin Trust (IBIT), the largest of the funds, lost about $234 million on October 30. Funds managed by Fidelity and Ark Invest recorded the next-largest exits. When investors redeem shares, large trading firms return fund shares in exchange for Bitcoin or cash. This process results in the funds releasing coins that can subsequently be sold on the open market.
Ethereum (ETH) funds lost an additional $156 million on the same day. This marked the fifth consecutive day of outflows for Ethereum-based investment products.
Scale of the Binance Theft
On October 29, an attacker moved roughly $6.36 billion out of Binance’s exchange wallets across 10 blockchains, according to analytics firm TRM. Most of the stolen funds were transferred within about 20 minutes. TRM linked the theft to TraderTraitor, a North Korean hacking unit.
The amount stolen is approximately four times the $1.5 billion Bybit hack that occurred in February 2025, which was the previous record for a single exchange theft. Binance suspended deposits and withdrawals following the incident and stated that user funds remain safe. Token issuers and network operators have frozen about $2.7 billion of the stolen assets, TRM reported.
Market Context and Historical Precedent
Friday’s exit represents about 0.7% of the total money held in the Bitcoin ETFs. A similar withdrawal occurred on October 22, when investors pulled $635 million in a single session. Inflows then returned for four straight days starting October 26.
However, the previous record hack was followed by heavier selling. A week after the Bybit theft, investors pulled a then-record $1 billion in one day. Outflows that week neared $3 billion. About $11 billion in Bitcoin options, contracts that bet on future prices, also expired on October 30.
The Bitcoin price sits at $77,189, down 1.7% in 24 hours. Monthly return data indicates Bitcoin is down 7.3% for October 2026 so far. The coin also fell 3.95% in October 2025. Back-to-back losing Octobers have occurred only once before in Bitcoin’s history, in 2011 and 2012. Historical data puts Bitcoin’s average October gain at 26%.
