Updated 21:32 UTC

New Developments on Binance Security Concerns

Tether has frozen approximately $971 million in USDT linked to suspected outflows from Binance’s hot wallets on October 29, 2026.

Circle has also reportedly frozen around $823 million in USDC, totaling over $1.7 billion in stablecoins frozen between the two companies.

Binance's founder, Changpeng Zhao (CZ), indicated that the situation appears to suggest a hack, while the exchange's security team is investigating the potential security issue.

Market observers noted that approximately $450 million in long positions were liquidated amid the turmoil following the withdrawals.

The freeze by Tether and Circle allows them to blacklist specific addresses, preventing tokens in those wallets from being moved.

As of now, the full extent of the outflows remains unclear, and it is still uncertain whether a hack definitively occurred.

Latest Developments on Binance Security Incident

On October 29, 2026, a suspected hack drained between $2.5 to $3.5 billion from Binance's hot wallets. Binance founder Changpeng Zhao reassured users that their funds are safe and that the exchange will cover any losses in full.

During a 40-minute window from 20:24 to 21:04 UTC, large amounts of ETH, USDT, and USDC were transferred from Binance's hot wallets. Analysts noted that the receiving addresses were new and funds were quickly moved again, raising suspicions of a hack.

Tether and Circle froze approximately $1.8 billion linked to the outflows, with $971 million in USDT and $823 million in USDC initially reported. Tether later adjusted its frozen total to around $1.5 billion.

Liquidations reached $627.7 million, primarily from long positions, and Bitcoin and ETH prices dropped by 2% to 4% shortly after the news broke. BNB, Binance's token, saw a decline of up to 6%.

Binance has launched an investigation into the incident, and the outcomes will be closely monitored, including how the attacker accessed the hot wallets and whether any user funds were ultimately affected.

New Developments

Tether has frozen over $1.567 billion in USDT linked to a suspected exploit of Binance, following approximately $3.3 billion in outflows from two Binance hot wallets on Ethereum on October 29, 2026.

The outflows occurred rapidly within a 40-minute window, prompting Tether to blacklist the receiving wallets. An initial freeze of around $971 million was later increased to more than $1.567 billion USDT.

Circle also froze approximately $823 million in USDC related to the same incident, resulting in a total immobilization of between $1.8 billion and $2.4 billion in stablecoins.

While Tether and Circle acted swiftly, around $700 million in USDT and ETH moved before the blacklisting could take effect, highlighting the challenges of issuer-level freezes.

Binance has not confirmed a hack but is investigating the incident, with former CEO Changpeng Zhao suggesting it resembled a hack while assuring that user funds are secure.

A wallet suspected of belonging to a Binance hacker is currently holding $47.3 million in UNI, making it the largest altcoin position linked to the address.

Here’s the breakdown of the disclosed holdings in the suspected wallet:

• UNI: $47.3 million
• ENA: $41.4 million
• PEPE: $38.5 million

Latest Developments

As of October 29, 2026, Bybit has confirmed that its platform is not affected by recent security incidents impacting other exchanges, including Binance and Polymarket. Trading and withdrawals on Bybit are operating normally, and user funds remain secure.

In response to the concerns surrounding Binance, Bybit has emphasized the importance of relying on official communication channels rather than social media rumors.

In a notable incident in February 2025, Bybit experienced a significant security breach where hackers stole between $1.46 and $1.5 billion in Ethereum. Following this, Bybit successfully processed over 580,000 withdrawal requests and covered the stolen amount within approximately 12 hours.

Bybit has since implemented upgraded security measures, including AI-assisted monitoring tools, which reportedly blocked over $700 million in potential losses from suspicious withdrawals earlier in 2026.

The recent actions by Tether and Circle to freeze transactions related to the Polymarket incident highlight the significant influence centralized stablecoin issuers have during crises.
