Blackstone, the anchor investor in a recent $63 billion deal to finance Anthropic's chips, now expects the AI lab to receive a high junk credit rating after its initial public offering. The claim comes from a Financial Times report that TechCrunch summarized on 31 October 2026.
What did Blackstone expect before, and what changed?
According to the Financial Times, as cited by TechCrunch, Blackstone had earlier told investors that Anthropic would receive an investment-grade rating before 2027. An investment-grade rating signals low risk to lenders. Blackstone now expects a double B range rating, which is the top tier of speculative junk grade.
The source does not say which credit rating agencies Blackstone spoke with, when they would decide, or what process would lead to a final rating.
Why a junk rating would matter to Anthropic
TechCrunch notes that Blackstone's forecast is only a prediction. Still, a high junk rating would make it harder and more expensive for Anthropic to raise the money it needs to keep funding its spending. The source describes that spending as the backbone of the company's business.
The concern is tied to the company's buying pattern. TechCrunch reports that Anthropic has been on a spending spree, signing large compute power deals over the past 12 months, and that this has worried investors.
As general finance background, credit ratings influence the interest rates lenders charge on bonds and loans. Lower-rated borrowers usually pay more to borrow. This is standard context rather than a statement from the source about Anthropic's actual loan or bond terms.
What the reporting leaves out
- The source does not name the rating agencies involved, and no agency has been quoted on the matter.
- It does not give the IPO date, the offering size, or a valuation.
- Anthropic and Blackstone both declined to comment when TechCrunch reached out, so the company's own view is not available.
- The reporting is secondhand. TechCrunch summarized the Financial Times report and did not publish the original text.
TechCrunch says Anthropic formally filed to go public earlier in the same week. The filing has started wider speculation about how a large AI IPO could affect the rest of the industry, but the source does not go into that question.
How to follow what happens next
The useful signal will be an official rating from a recognised agency, not a forecast relayed by an investor. If a rating is issued, it will be published by the agency and will likely appear in the company's IPO disclosures.
For readers who depend on Anthropic's products or pricing, the source contains no information about changes to the Claude service, API prices, or terms. Those questions remain open. Readers who follow the financing side can watch for the company's disclosures about debt, its compute commitments, and any new financing deals, since those will show whether lenders' expectations shift.
Who should pay attention and where the evidence stops
Investors, enterprise buyers of Claude, and developers who build on Anthropic's services have the most to gain from tracking this story. Investors can compare any official rating with Blackstone's earlier and current forecasts. Enterprise buyers can watch for any sign that the company's financial position affects its service planning.
The evidence is thin. It rests on one reported forecast from one investor, with no comment from either party and no named agency. Treat the report as a signal worth watching, not as a settled outcome.
Bottom line: Treat the expected junk rating as a reported forecast from one investor, not a rating decision. If you depend on Anthropic's financing or services, wait for an official rating and the company's own filings before drawing conclusions.
