[Blackstone Downgrades Anthropic Rating Forecast; Supplier Credit Guarantees Become More Important] According to a report by Jinse Finance on October 31st, citing sources familiar with the matter, Blackstone Group told investors that Anthropic may not immediately receive an investment-grade credit rating after its IPO, and is more likely to receive a double-B or higher rating, a shift from its previous expectation of obtaining an investment-grade rating by the end of the year. Due to investment restrictions imposed on some insurance companies and pension funds, making it difficult for them to hold large amounts of junk debt, Anthropic's future financing channels may be limited, and it may continue to rely on high-credit-rating suppliers to support its debt financing.
