Binance released Security Incident Update Announcement #2 at 3:33 AM today, disclosing its 24-hour investigation and asset compensation progress. The announcement noted that at 04:05 UTC+8 on October 30, 2026, Binance’s hot wallet was hacked, resulting in losses of approximately $6.3 billion in token assets. Binance emphasized that it will fully cover all losses via its SAFU Fund and corporate capital, with no losses passed on to users. To date, Binance has secured over $6.34 billion in corporate funds: more than $5 billion equivalent in assets including USDC, USDT, BTC, ETH and BNB are already in place, around 80% of the stolen funds have been replenished, while the remaining portion is being acquired via market and over-the-counter (OTC) channels. Earlier, Binance froze roughly $3 billion in assets on-chain. Regarding the attack’s cause, Binance said initial probes pointed to a compromised laptop as a possible factor, but subsequent investigations uncovered additional intrusion vectors. No evidence of wallet private key leakage has been found so far, with further technical investigation results expected in approximately 48 hours. For next steps, Binance is targeting to restore withdrawal services in phases within around 34 hours, subject to security check progress; it plans to conduct its first Proof of Reserves snapshot within 12 hours, with results to be published by November 2. Additionally, Binance will continue collaborating with law enforcement agencies, blockchain intelligence firms and asset issuers to track and recover stolen funds, and will release a full technical review report.

Beating AI News Flash: According to the Financial Times, citing sources familiar with the matter, Blackstone has informed investors in Anthropic’s latest $63 billion chip financing deal that the AI firm may not immediately obtain an investment-grade credit rating after its IPO, and is expected to receive a high-grade non-investment-grade (junk) rating. This contradicts Blackstone’s earlier guidance that Anthropic would secure an investment-grade rating by the end of the year. The development could limit Anthropic’s financing options, as many insurance and pension funds are barred from making large investments in junk-rated borrowers. Anthropic may need to continue relying on high-credit-rating providers to support its financing. Its prospectus shows the company plans to invest over $800 billion in building computing infrastructure by 2045. Securing an investment-grade credit rating is critical to meeting these targets, as it would enable Anthropic to borrow at lower interest rates to fund its AI infrastructure projects. The group holds more than $112 billion in cash and equivalents, and investors expect it to raise an additional roughly $100 billion in its IPO. In the "Project North Star" financing, over $42 billion in senior loans are guaranteed by Broadcom. The $18 billion subordinated debt has received a BB+ rating from KBRA with a positive outlook, and a BB rating from Morningstar DBRS. A Blackstone fund has invested $9 billion in this tranche, with a yield exceeding 10%. The three major rating agencies—Fitch, Moody’s, and S&P—have not yet formally assigned a credit rating to Anthropic.
