Bitcoin ETFs Hit $643M Outflow After Binance’s $6.3B Hack

• Record $643 million pulled from US spot Bitcoin ETFs, led by BlackRock and Fidelity, following Binance security breach
• Investor fears sparked negative monthly flows for Bitcoin and Ether ETFs; Ether sees historic $1.61 billion October withdrawal

On November 2, 2026, CoinDesk reported that US spot Bitcoin ETFs suffered $643 million in outflows on Friday—marking the biggest single-day pullback since June after Binance’s $6.3 billion hack rattled crypto markets. BlackRock’s iShares Bitcoin Trust (IBIT) posted the largest daily outflow at $234 million, with Fidelity’s Wise Origin Bitcoin Fund (FBTC) seeing $201 million withdrawn.

Investor anxiety over exchange security intensified after the Binance hack and subsequent user withdrawals. CNBC confirmed that $3.64 billion left Binance after it reopened, further fueling crypto sector selling. Bitcoin dropped to $77,000 on Friday, and ETF withdrawals spread beyond Bitcoin as Ether ETFs lost $156 million in a single day and saw a record $1.61 billion net withdrawal in October, erasing 2026 gains and resulting in $45 million in cumulative outflows for the year.

The scale of ETF redemptions underscores how both institutional and retail investors remain highly sensitive to exchange breaches, even though ETF asset custody is separate from centralized trading platforms. Negative sentiment drove net outflows for both Bitcoin and Ether ETFs, highlighting ongoing concerns about crypto market infrastructure. These events echoed prior incidents like the Bybit hack in February 2025, reinforcing volatility in crypto ETF investments.

As of November 2, 2026, 11:09 UTC, Bitcoin (BTC) trades at $77,808.98, down 0.10% in 24-hour volume. Ethereum (ETH) trades at $2,282.53, up 0.70%, according to CoinMarketCap.
