Blackstone has predicted that Anthropic will receive a high junk rating following its initial public offering. The investment firm anticipates the rating will fall into the double B range, which is the highest tier of speculative grade. This forecast comes after Anthropic filed for its IPO the week of 30 October 2026.
The rating downgrade marks a shift from Blackstone’s previous outlook, which predicted an investment-grade rating before 2027. A high junk rating would make raising capital more difficult and expensive for the company. This concern is likely linked to the massive spending Anthropic has incurred on compute power deals over the last 12 months.
Investors have reportedly grown worried about the company’s heavy spending, which has fueled the speculation surrounding the IPO. The shift from an investment-grade to a junk rating would signal financial risk to potential backers. Developers and investors should monitor the company’s cost management as it enters the public market.
