Investment giant Blackstone, which holds $9 billion in exposure to AI firm Anthropic, now expects the creator of Claude to receive a junk credit rating following its upcoming Nasdaq debut. The warning reverses Blackstone's previous projection of an investment-grade rating by year-end, raising questions over borrowing costs for Anthropic's ambitious $800 billion spending plan.
Key Takeaways
- Blackstone expects Anthropic to land in the BB-range speculative credit bracket after its Nasdaq debut.
- Anthropic's $63 billion Project North Star chip financing relies on $42 billion in Broadcom guarantees and $18 billion backed solely by Anthropic.
- Blackstone funds acquired $9 billion of the unbacked debt slice at yields exceeding 10%.
- Anthropic holds over $112 billion in cash reserves and aims to raise roughly $100 billion in its late-November IPO.
Credit Rating Expectations Reversal
According to a report from the Financial Times on Thursday, Blackstone informed investors that Anthropic will likely receive a BB-range rating from major agencies. Credit ratings below BBB- are categorized as junk, restricting access to investment capital from institutional funds and insurers with strict mandate caps. In June, Kroll Bond Rating Agency (KBRA) assigned Anthropic a BB+ rating, placing the company one notch below investment grade.
Major credit rating agencies Fitch, Moody's, and S&P have not yet issued their ratings ahead of the company's expected late-November listing. While Wall Street underwriters Goldman Sachs and Morgan Stanley pushed for investment-grade status in September, rating agencies remain hesitant. In contrast, SpaceX secured investment-grade ratings from all three major agencies days after its June IPO.
Project North Star and Debt Distribution
The credit rating decision directly impacts Anthropic’s $63 billion chip financing arrangement, designated as Project North Star. Within this capital structure, $42 billion in debt carries a guarantee from Broadcom, an investment-grade chip manufacturer. However, the remaining $18 billion rests entirely on Anthropic’s own credit profile. Blackstone funds absorbed $9 billion of that direct exposure at yields above 10%.
As institutional investors track the AI developer's debt standing, financial management platforms continue expanding Anthropic integrations while crypto exchanges launch Anthropic derivative products. Anthropic’s IPO prospectus characterizes its compute expansion plan as "bold but sane." The company currently holds more than $112 billion in cash and anticipates raising approximately $100 billion in additional capital through its public filing.
Why It Matters
A sub-investment grade rating for Anthropic highlights growing institutional skepticism regarding aggressive AI capital expenditure strategies relative to near-term profitability. Higher borrowing costs could make long-term debt financing substantially more expensive, putting pressure on tech firms to rely on equity dilution for multi-billion-dollar compute centers. Investors should monitor the post-IPO rating announcements from Moody's, S&P, and Fitch following the late-November debut, as their decisions will establish borrowing benchmarks for the broader artificial intelligence sector.
