Blackstone tells investors Anthropic may miss investment-grade rating post-IPO

The signal here is less about Anthropic's IPO mechanics than about how a major private-markets allocator is now framing AI-lab credit risk to its own investors. A sub-investment-grade profile would matter most to debt-focused and rating-constrained portfolios, and the shift from earlier guidance suggests the underwriting conversation has turned more cautious. Whether that reassessment stays confined to Anthropic or colors how other large AI issuers are priced at the public-market threshold is the open question.
