Blackstone expects AI company Anthropic to receive a "high-junk" credit rating after its IPO, the Financial Times reported. Blackstone, a major investor in Anthropic's recent $63 billion chip financing deal, told investors it expects Anthropic's rating to fall into the highest tier of speculative-grade "junk" ratings (the double-B range). Blackstone had previously expected Anthropic to achieve an investment-grade rating by 2027. Anthropic officially filed for an IPO earlier this week, and a high-junk rating would make its financing more difficult and costly.
