Binance $6.3 Billion Breach Sends Bitcoin to a Six-Week Low
Binance, the world's largest crypto exchange, is facing what analysts are calling the biggest hack in history. With estimates still evolving and billions frozen across networks, markets sold off as traders waited for clarity.
Highlights
- Binance reported a potential security issue on Thursday 29 October 2026, with an estimated impact of $6.3 billion
- Chainalysis confirmed at least $5.912 billion stolen as of 8:30 p.m. ET, with funds moving across multiple blockchains
- Tether, Circle and Ripple froze billions in stablecoins as Binance suspended deposits, withdrawals and Binance Alpha trading
- Bitcoin hit a six-week low, falling 3% to $76,469.82 in one Reuters snapshot, while ether and crypto stocks also fell
- The figures are evolving and differ by source and time, and Binance has said user funds were safe
What Binance reported
Binance, the world’s largest crypto exchange with over 335 million registered users, reported a potential security issue on Thursday 29 October 2026, and prices fell further in early Asian trading on Friday 30 October Reuters.
Binance put the estimated impact at $6.3 billion and gave no update on the remaining $3.3 billion after roughly $3 billion was frozen or located Reuters. That figure is an estimate, not a Binance-confirmed single loss figure. Other trackers gave different figures, including $5.7bn in outflows and around $5.8bn in attacker wallets, explicitly not confirmed.
Binance co-founder Changpeng Zhao wrote on X that it “looked like a hack”, while Binance said on X that user funds were safe Reuters. Co-founder Yi He made the clearest commitment to customers:
“Binance will cover all hacking losses,” — Yi He, Binance co-founder Reuters
How much was taken — and why the numbers differ
Chainalysis head of research Eric Jardine gave the most detailed confirmed figure:
“The investigation is ongoing, and we cannot yet confirm the cause of the hack. As of 8:30 p.m. ET (0030 GMT), we have confirmed that at least $5.912 billion was stolen, with funds moving across multiple blockchains, including Bitcoin, Ethereum, Tron, Ripple and several Layer 2 networks.” — Eric Jardine, Chainalysis Reuters
The words “at least” and the specific time matter. Different trackers count at different cut-off times, include different networks, and treat frozen funds differently. That is why estimates from $5.7 billion to $6.3 billion can appear on the same day. The accurate reading on 30 October is an evolving total anchored by the Reuters figures, not a final audited loss.
The freeze effort
Tether froze nearly $1.57 billion and Circle over $800 million on Thursday — over $2.38 billion of stablecoins in total Reuters. Ripple froze roughly $200 million, according to Binance co-founder Yi He on X, via Reuters Reuters. The initial frozen total was $2.54 billion, according to Binance via Reuters, later updated to around $3 billion Reuters.
Freezing can limit how easily stolen funds are moved, but frozen is not the same as returned. Binance also temporarily suspended deposits and withdrawals and halted trading on Binance Alpha, while Binance.US said it was not affected Reuters.
Markets sell off
Bitcoin hit a six-week low, and one Reuters snapshot on 30 October had it down 3% at $76,469.82, with ether down over 3% at $2,185.83 Reuters. BNB fell over 8% to $694 in an earlier report, Coinbase slid 4.8% and Strategy fell nearly 6% Reuters.
The selling came when risk assets were already under pressure — in a related move, gold and silver sold off ahead of the Fed meeting — which helped the shock spread quickly. Aravind Srinivasan of GSR explained the trading conditions:
“It’s the biggest hack in history… spreads are wider and liquidity is thin in Binance too on spot.” — Aravind Srinivasan, GSR Reuters
Wider spreads mean traders pay more to get in or out, and thin liquidity on the world’s largest exchange matters because other venues look to it for price discovery.
How analysts reacted
“We don’t have a large position on Binance. It accounts for less than 20% of our overall holdings. But for the positions we do have there, we’ve sold everything for now.” — Amanda He, ChainUp Investment CIO Reuters
That illustrates the trust problem: a position can be under 20% of holdings and still be sold first when operational risk rises, especially while the cause remains unconfirmed.
The scale also dwarfs earlier incidents. The previous record crypto hack was Bybit’s around $1.5 billion loss in February 2025, while TRM Labs counted $2.9 billion stolen across nearly 150 attacks in 2025 Reuters. The confirmed Chainalysis figure alone is larger than that full-year total for 2025.
What this means
Three things will decide how this ends. First, recovery: how much of the frozen roughly $3 billion is returned, and what happens to the remaining $3.3 billion. Second, explanation: until the cause is confirmed, confidence will stay fragile. Third, the cover promise: Yi He’s statement that “Binance will cover all hacking losses,” will be tested by how completely affected users are made whole.
For now, the most accurate summary is a careful one: a potential security issue reported on 29 October, an estimated $6.3 billion impact, at least $5.912 billion confirmed stolen by Chainalysis at a specific time, billions frozen by Tether, Circle and Ripple, and an investigation still ongoing. Any firmer number would go beyond what the sources have confirmed.
