Bitcoin ETFs See $643M Outflows Day After Record Binance Theft

US spot Bitcoin ETFs lost $643.33 million on October 30, based on SoSoValue data. The withdrawal came a day after roughly $6.3 billion was drained from Binance, the largest crypto exchange in the world.

These vehicles allow brokerage customers to own Bitcoin (BTC) in the same way they would own a stock. The products hold $98.14 billion in assets, and Friday's redemptions halted a four-day inflow sequence.

Where Did the Biggest ETF Losses Land?

About $234 million was pulled from BlackRock's iShares Bitcoin Trust (IBIT), the biggest product in the group. Fidelity- and Ark Invest-run funds recorded the largest outflows after that.

In a redemption, big trading firms hand back fund units for Bitcoin or cash. In either case, the vehicles hand over tokens that may subsequently be sold on the open market.

That same day, Ethereum (ETH) funds saw an extra $156 million leave, making it five outflow sessions in a row.

What Was the Scale of the Binance Attack?

According to analytics firm TRM, an attacker moved roughly $6.36 billion out of Binance's exchange wallets on October 29, touching 10 blockchains. The majority left in about 20 minutes.

TRM connected the heist to TraderTraitor, a hacking group tied to North Korea. The amount is roughly four times the $1.5 billion stolen from Bybit in February 2025, which had been the largest such breach.

Binance paused deposits and withdrawals, saying customer funds are protected. According to TRM, token issuers and network operators have frozen about $2.7 billion of what was taken.

Is a Single Day of Redemptions a Warning Sign?

Friday's redemptions amount to roughly 0.7% of the assets in these products.

A similar pullback took place on October 22, with $635 million withdrawn over a single session. After that, inflows resumed for four days in a row from October 26.

The prior record hack, however, was followed by even steeper selling. ETF.com reported that one week after the Bybit theft, $1 billion exited in a day — a record at the time. Weekly outflows came close to $3 billion.

Will Bitcoin Post a Second Straight Losing October?

Also maturing on October 30 was about $11 billion in Bitcoin options, instruments used to speculate on future price levels. Bitcoin now trades at $77,189, down 1.7% over 24 hours, according to BeInCrypto.

Trader Crypto Rover shared monthly return data placing Bitcoin 7.3% lower for October to date. In October 2025, the coin dropped 3.95% as well.

Only once before, in 2011 and 2012, have back-to-back Octobers ended in the red. Bitcoin's average October gain, per the same data, stands at 26%.

For those holding the funds, upcoming sessions will reveal whether Friday's outflow is closer to October 22 or February 2025.
