• Binance reports $6.3 billion theft, largest crypto hack on record, triggering broad selloff.
  • Coinbase and Strategy (MSTR) shares fall sharply, but for different reasons: Coinbase says it was unaffected, while Strategy is exposed via bitcoin holdings.
  • Binance freezes about $3 billion of affected assets and pledges to cover all losses; withdrawals targeted for restoration within 45–48 hours.

Market Rout Hits Crypto Equities

Crypto-related stocks tumbled Thursday after Binance disclosed a $6.3 billion theft, the largest in crypto history, rattling an already fragile market. Coinbase Global (COIN) $COIN dropped 12.4% and Strategy $MSTR fell 11.9%, according to a social-media post, though separate reporting documented earlier after-hours declines of 4.8% and nearly 6%, respectively. The exact intraday percentages could not be independently verified.

The selloff underscores a key distinction: Binance suffered the breach, Coinbase says it was unaffected, and Strategy’s exposure stems primarily from its massive bitcoin holdings. “The market is treating this as a sector-wide confidence shock, but the fundamentals differ sharply,” said a person familiar with the matter.

Frozen Assets and Reimbursement Plans

Binance has frozen roughly $3 billion of affected assets through coordination with token issuers and partners, including Tether, Circle (CRCL), and Ripple, which froze $1.57 billion, over $800 million, and about $200 million, respectively. However, freezing does not equal recovery—returning assets requires legal and operational steps. Roughly $3.3 billion remained unfrozen in the reporting reviewed.

The exchange pledged to cover all hacking losses and has set aside $6.34 billion, including $5 billion already held in affected asset types, and is purchasing the remainder in markets and over the counter. These are company statements, not independently verified. Withdrawals remain disrupted, with Binance targeting restoration within 45–48 hours. Initial reports described suspension of both deposits and withdrawals; later reports say deposits are unaffected.

Investigation Points to Compromised Laptop

The preliminary investigation points to a compromised engineer’s laptop and additional breach points. Binance says it has found no evidence of leaked wallet private keys, and the precise attack mechanism is not yet established publicly. TRM Labs and Chainalysis attribute the attack to North Korea with high confidence, though Binance says its investigation has not attributed responsibility. North Korea routinely denies such allegations.

The incident comes shortly after the U.S. Office of the Comptroller of the Currency finalized its GENIUS Act stablecoin rule on October 21, effective January 18, 2027. The rule covers reserve backing, redemption, and risk management, but does not guarantee against exchange hacks.

Company Exposures Diverge

Coinbase reported Q3 net income of $719 million, adjusted net income of $78 million, and adjusted EBITDA of $333 million, up 60% quarter over quarter. A $715 million investment-crypto gain boosted GAAP earnings, so headline profit overstates operational improvement. Subscriptions and services represented 49% of Q3 net revenue, and average USDC held in its products reached $22 billion.

Strategy reported 848,517 bitcoin as of October 25, with a $64.02 billion cost basis and $68.90 billion market value. Its Q3 release showed revenue of $125.4 million, down 3% year over year, and $19.12 billion in net income attributable to common shareholders, including a $20.91 billion digital-asset gain. Following shareholder approval on October 28, Strategy changed four preferred-stock series to daily dividend accrual and has raised $21 billion of equity capital year to date.

Broader Market and Regulatory Fallout

The shock struck an already vulnerable market. Higher U.S. interest rates and softer demand from bitcoin ETF buyers had been weighing on crypto before the breach. Bitcoin subsequently reached $76,368, a six-week low, while ether touched $2,178 before stabilizing.

Moody’s (MCO) analyst Cristiano Ventricelli emphasized that broader credit consequences depend on final losses, affected counterparties, recovery, and whether disruption spreads across the digital-asset ecosystem. “The key is not the headline size but the ultimate loss and confidence effects,” he said. CertiK CEO Ronghui Gu added that sustained confidence will depend on effective resolution, customer protection, and transparent disclosure.

HashKey (3887.HK) researcher Tim Sun warned that investors may reassess the safety of assets on centralized exchanges, potentially weakening risk appetite. The freezes demonstrate the influence of intermediaries able to block transfers, but freezing alone does not establish that users have been repaid.

The closest precedent is Bybit’s $1.5 billion theft in February 2025, which the FBI attributed to North Korea. Binance’s reported loss is more than four times that amount. Other comparisons include Mt. Gox’s collapse after a $500 million theft and Bitget’s approximately $350 million theft in September 2026.

Coinbase and Strategy also released earnings on October 29, so their stock movements occurred amid both the Binance shock and company-specific disclosures. Attributing every percentage point to the hack would overstate what the evidence establishes.

Binance did not respond to a request for comment. Coinbase declined to comment. Strategy could not be reached for comment.
