Anthropic faces potential junk credit rating after IPO, Blackstone warns
Blackstone has warned investors that Anthropic is likely to receive a below-investment-grade credit rating in the double-B range following its IPO, according to the Financial Times.

Anthropic is expected to receive a below-investment-grade "high junk" credit rating in the double-B tier after going public, Blackstone told investors, according to a report from the Financial Times. The warning reverses Blackstone's earlier guidance that had anticipated an investment-grade rating for the artificial intelligence company by year-end.[1][2][3][4]
A junk rating could increase Anthropic's borrowing costs and restrict access to institutional capital, including pension funds and insurers bound by mandates against holding junk-rated debt. Major rating agencies Moody's, S&P, and Fitch have not yet formally issued credit ratings for the company.[1][2]
The prospect of a lower rating comes as Anthropic prepares for extensive capital outlays. The company's IPO prospectus outlined plans to spend more than $800 billion on computing infrastructure through 2045, even as it reportedly holds over $112 billion in cash and could raise another $100 billion through its public listing.[1][2]
Blackstone is currently participating in Anthropic's $63 billion Project North Star financing package to lease 1.5 gigawatts of Google AI chips. In that transaction, more than $42 billion of senior loans are guaranteed by Broadcom, while $18 billion in junior debt is backed by Anthropic's lease payments. Blackstone funds invested $9 billion into the junior debt at yields above 10%. Without an investment-grade rating of its own, Anthropic may have to keep relying on stronger corporate partners to anchor future debt financing.[1][2]
