The Financial Times reports that Blackstone has given investors in the big chip financing deal a revised expectation: after its public offering, Anthropic will land a high junk rating rather than an investment-grade one. That means the double-B range, the top tier of speculative grade.
Blackstone is the anchor investor in the $63 billion vehicle financing Anthropic’s Broadcom chips. According to the FT, the same firm previously told those investors that Anthropic would get an investment-grade rating before 2027. Anthropic and Blackstone both declined to comment to TechCrunch.
Why two letters cost money
A rating is not a verdict on the product. It is a price for debt. Investment grade means pension funds and insurers are allowed to buy, and at low rates. Double B means a much smaller pool of buyers, wider spreads and tighter covenants. For a company buying compute in ten-billion-dollar increments, that is not a line item. It is the difference between two investment plans.
Which is precisely what investors are nervous about. Anthropic has signed a string of very large compute contracts over the past year, all of them leaning on debt. More expensive debt makes the next round of those contracts harder.
A forecast, not a rating
What exists here is Blackstone’s expectation, not an agency’s rating. Moody’s, S&P and Fitch have published nothing, and the company is not public yet. So the news matters for the reversal, not the number: the anchor investor flipped its own assessment within months, and flipped it in front of people who invested on the strength of the old one.
The S-1’s risk list gets its first outside confirmation
Anthropic wrote these risk factors into its own S-1 four days ago, and Elizabeth Warren pointed at exactly those passages in her letter to Dario Amodei. Blackstone’s revised expectation is the first voice arguing neither as press nor as politics but as a lender — and it comes from the lender most exposed. It says nothing about where the stock will trade. It says a great deal about what the next data center will cost.
