A significant security incident at Binance dominated this week's cryptocurrency headlines, alongside major developments in prediction markets and institutional tokenization services.
Binance's investigation linked unauthorized withdrawals to a compromised laptop belonging to a DevOps engineer, which allowed access to a service container for submitting unauthorized transactions. Estimated losses from the incident range from $2.77 billion to $6.5 billion, marking what analysts consider the largest crypto hack by dollar value to date.
Prediction Markets Surge
Prediction-market operator Kalshi secured $1 billion in new funding, bringing its valuation to $40 billion. This represents an 82% increase from the company's $22 billion valuation in May. The funding milestone places Kalshi at a valuation comparable to Coinbase, despite Coinbase's six-year head start in the American crypto industry.
Corporate Custody Risks Highlighted
A Nasdaq-listed company lost access to 817.6 bitcoin held in custody, resulting in a 50% stock decline. The incident underscores vulnerabilities in various custody arrangements, from centralized exchanges to digital asset trusts, as corporate cryptocurrency treasuries proliferate.
Coinbase Returns to Profitability
Coinbase reported $719 million in net profit for the third quarter of 2026, reversing two consecutive quarterly losses. However, approximately $715 million of this profit came from gains on cryptocurrency held as investments. Adjusted net income, excluding these gains, was $78 million, while operating income from exchange operations was $61.7 million, down from $480.5 million a year earlier.
DTCC Launches Tokenization Service
The Depository Trust & Clearing Corporation launched a blockchain tokenization service connecting traditional Wall Street infrastructure with digital markets. The service oversees a custody network managing more than $114 trillion in securities. Major banks have signed on to the initiative, though questions remain about retail investor access to the tokenization trend.
