Key Highlights

● Circle froze more than 800 million USDC linked to the record Binance hack.

● Circle shares slipped 2.11% in early trading, far less than other crypto-linked stocks.

● Binance estimated the total impact at about $6.3 billion, with roughly $3 billion frozen on-chain.

● Bitcoin fell to an overnight low of $76,400 before recovering to about $77,350.

Circle Internet Group (NYSE:CRCL), the issuer of the USDC stablecoin, has frozen more than 800 million USDC linked to the record hack at Binance, the world's largest crypto exchange. "In coordination with law enforcement, we have frozen more than 800M USDC associated with the incident," CEO Jeremy Allaire said, according to media reports.

Circle's shares nonetheless slipped in early trading. Market data showed the stock down 2.11%, and one report said Circle was declining in pre-market trading, as of a report published at 4:34 a.m. ET. The move is far smaller than the 5% to 6% declines in Coinbase (NASDAQ:COIN), Robinhood (NASDAQ:HOOD) and Strategy (NASDAQ:MSTR) reported by another source.

Tether, the largest Stablecoin issuer, also acted. Its chief executive said on X that it had frozen more than 1.567 billion USDT linked to a potential Binance hack, according to media reports.

The scale of the hack

Binance estimated the total impact at about $6.3 billion and said roughly $3 billion had been frozen on-chain, according to media reports. Another report said about $6.36 billion was taken across 10 blockchains in around 20 minutes, starting at 20:05 UTC Thursday, more than four times the $1.5 billion Bybit hack of February 2025.

Media reports said blockchain analytics firms attributed the attack to hackers linked to North Korea. Binance suspended deposits and withdrawals, said it would cover losses from its Secure Asset Fund and company funds, and stated that "User funds are safe."

The market fallout was swift. Bitcoin fell to an overnight low of $76,400, its lowest since Sept. 18, before recovering to about $77,350, and ether briefly touched $2,170, according to media reports. Crypto futures liquidations quadrupled to $1.57 billion. Lending protocol Aave froze markets across 16 networks after the attacker borrowed about $44.6 million of ether against stolen USDT, according to the same reports.

Why it cuts both ways for Circle

For Circle, the episode is a double-edged test. On one hand, the ability to freeze tokens quickly and work with law enforcement shows the compliance controls that regulated stablecoin issuers promote as a selling point, and it may help limit how much stolen value the attackers can move.

On the other hand, Circle's Business depends on the overall size and activity of the crypto market. Its Revenue is largely tied to the reserves backing USDC, so a broad loss of confidence that shrinks stablecoin balances or trading activity would be a headwind. Stocks tied to crypto are trading as a group this morning, and Circle is not immune.

Circle trades on the New York Stock Exchange and is part of the NYSE Composite. The wider Equity tape is weak, with Nasdaq-100 futures down about 2.6% and S&P 500 futures about 1.1% lower around 8 a.m. ET, according to market data, as Amazon (NASDAQ:AMZN) and Intel (NASDAQ:INTC) results rattled the AI trade.

There are reasons the damage may stay contained. One analyst called it "likely the largest crypto hack on record" but said it did not currently appear to be a Solvency problem for Binance, according to media reports. Spot bitcoin ETFs had seen four straight days of inflows before the theft, media reports noted.

Key risks include further breaches; media headlines said Binance had found additional ones. Regulatory fallout, or questions about how much of the frozen USDC can ultimately be returned, could also weigh. Watch for updates from Circle on the frozen funds, Binance's timeline for reopening withdrawals, and whether bitcoin holds the $76,000 area after U.S. markets open.
