Blackstone Shifts Outlook on Anthropic Credit Rating Ahead of IPO

The revised outlook places Anthropic in the double B range, the highest category within speculative credit grades. While Blackstone remains a key backer, having recently participated in a $63 billion financing deal for the company’s compute infrastructure, this cooling sentiment highlights growing concerns over the lab’s aggressive spending habits. The firm declined to comment on the shift, as did representatives for Anthropic.

A junk rating would complicate the company’s path to future capital, likely increasing the cost of borrowing as it continues to fund massive compute power acquisitions. Anthropic officially filed for its public offering this week, an event that has sharpened industry focus on the sustainability of the capital-intensive AI business model. As the IPO approaches, this downgrade in credit expectations serves as a reminder of the volatility inherent in the current race for artificial intelligence supremacy.
