TL;DR
The Financial Times reported that Blackstone expects Anthropic to receive a double-B, non-investment-grade rating after its planned IPO, reversing an earlier expectation of investment grade before 2027. That is a forecast attributed to one lender, not a rating decision: Anthropic has filed to go public, but Moody’s, S&P and Fitch have not announced ratings.
The Financial Times reported on October 30 that Blackstone expects Anthropic to receive a double-B, non-investment-grade credit rating after its planned stock market debut, a shift from an earlier expectation that the AI company would reach investment grade before 2027. The forecast is not a rating-agency decision: Moody’s, S&P and Fitch have not announced ratings, and Anthropic’s IPO filing does not set a share price or listing date.
The FT report, summarized by TechCrunch, says Blackstone shared its revised expectation with investors in a $63 billion chip-financing deal involving Anthropic. Blackstone is the sole provider of the committed portion of the deal’s second-lien financing, according to a joint announcement. Second-lien financing ranks behind senior loans in repayment priority, making it a riskier part of the funding structure. Blackstone and Anthropic declined to comment when contacted by TechCrunch.
The reported double-B range sits below the investment-grade threshold, which is generally BBB-minus or higher. It is a measure of perceived risk in repaying debt, not a grade for Anthropic’s shares and not a declaration that the company is close to default. Credit ratings are opinions about credit risk and can change; the Securities and Exchange Commission says ratings apply to debt securities, not common stock.
Anthropic’s October 26 registration statement confirms that the company has not yet met a borrowing agreement’s condition requiring investment-grade ratings from at least two of the three major agencies. The filing says its $15 billion credit line is secured by substantially all of its assets until that condition is met. It also reports $6.2 billion in debt as of June 30, all in convertible notes held by Amazon. These disclosed terms establish the rating condition and existing debt, but do not confirm Blackstone’s forecast.
WHAT IS CONFIRMED, WHAT IS REPORTED
A junk rating for Anthropic? A forecast, not a rating
One investor's expectation, reported by one newspaper, against what Anthropic's own filing shows.
In the documents
- No investment grade from two of Moody’s, S&P and Fitch yet: the $15B credit line stays secured until then (S-1, p. 164)
- IPO filed 26 Oct, Nasdaq symbol “ANT”; shares, price range and date not set
- $63B chip deal: Blackstone is the sole committed second-lien lender; Broadcom backs up to about $43B
From the FT, via TechCrunch
- Blackstone told investors it now expects a “high” junk rating, in the double-B range, after the IPO

The rating ladder, in plain words
Typical scale. Ratings grade debt, not stock, and are predictions that can change.
- AAAhighest grade

- BBBlowest investment grade, down to BBB-minus
- Investment grade ends here
- BBtop of speculative grade: Blackstone’s reported expectation for Anthropic
- B · CCCspeculative, higher risk
- Ddefault
What the SEC says
- Many agencies draw the line between “BBB” and “BB”: BBB-minus or higher is investment grade
- Below it is non-investment grade, also called “speculative” or “high yield”. “Junk” is the nickname
- Credit ratings “do not apply to equity securities like common stock”
- Ratings are “simply a prediction” and can change “at any time”
- The big agencies are often paid by the companies they rate, a conflict they must disclose

How a Rating Could Affect Anthropic’s Borrowing
A rating below investment grade could affect the price and availability of future borrowing, since lenders may demand higher returns for taking on greater perceived risk. The distinction matters for a company financing large-scale computing infrastructure: its ability to secure capital on workable terms can influence how quickly it expands capacity and what financial commitments it takes on. Those are potential consequences, not outcomes established by the FT report.
The public documents describe a tension between growth and obligations rather than a simple picture of financial distress. Anthropic reported $16.3 billion in revenue during the first half of 2026 and said cash from operations turned positive. At the same time, its filing lists extensive compute-related commitments, many of which it says are payable regardless of actual usage. Those commitments could shape how lenders assess future cash needs, but the reported rating forecast does not identify the reasoning Blackstone gave for its view.
For customers and users, a possible speculative-grade rating does not mean Claude service is about to stop. Any indirect effect would depend on how financing costs, infrastructure plans and customer agreements develop. The report alone does not establish changes to service availability, pricing or product plans.

IPO Filing and Financing Structure
Anthropic filed its registration statement with U.S. regulators on October 26, 2026, and said it plans to list on Nasdaq under the symbol ANT. The filing is a step toward a public offering, not a completed IPO: the share count, price range and listing date had not been set in the source material. A public debut could bring added scrutiny and information about the company, but it would not itself determine a credit rating.
The $63 billion financing arrangement is structured through a newly formed special-purpose vehicle that buys Broadcom accelerators and networking equipment and leases them to Anthropic, according to the parties’ October 26 announcement. Broadcom’s filing says it provides residual-value support of up to about $43 billion. These elements describe the financing arrangement; they do not amount to a published assessment of Anthropic’s credit quality.
The source material also calculates that named compute contracts total about $637 billion. That figure is the article author’s sum of commitments in the filing, not a single total presented by Anthropic as a company liability. The filing says some payments are due regardless of actual usage. That distinction is relevant when considering fixed commitments, but the total should not be confused with current debt or cash owed immediately.
“Both declined to comment.”
— Anthropic and Blackstone, through their responses to TechCrunch
No Agency Rating Has Been Announced
The key uncertainty is whether Moody’s, S&P or Fitch will issue a rating, what that rating would be, and when any decision might come. The source material reports no public rating from those agencies. It also does not provide a direct statement from Blackstone explaining the reported change in its outlook; the FT article is behind a paywall, and the available account comes through TechCrunch’s summary.
Accordingly, the claim that Blackstone now expects a double-B rating—and the claim that it previously expected investment grade before 2027—remain reported expectations, not independently confirmed decisions. The IPO could also change timing or financing conditions, but the supplied material does not establish how or whether it would affect agency assessments. No conclusion about Anthropic’s future rating should be treated as settled.
Agency Decisions and IPO Terms
The next observable milestones are the publication of any credit assessments by Moody’s, S&P or Fitch and further progress on Anthropic’s proposed Nasdaq listing. The company’s filing does not yet specify the share price range, number of shares or listing date, so those terms remain outstanding. Investors and customers will also be able to assess later disclosures against the debt and compute commitments already described in the filing.
Until an agency publishes a rating or Anthropic and Blackstone provide more detail, the reported double-B expectation should be treated as one lender’s forecast. A rating, if issued, would address debt repayment risk; it would not by itself determine the value of Anthropic’s shares or establish that its services will change.
Key Questions
Has Anthropic received a junk credit rating?
No rating from Moody’s, S&P or Fitch is identified in the source material. The double-B assessment is described as Blackstone’s expectation in a Financial Times report summarized by TechCrunch.
What does a double-B rating mean?
Double-B is below the usual investment-grade threshold of BBB-minus. It is commonly called speculative grade or junk and indicates higher perceived debt risk; it is not the same as a default declaration.
Does a possible junk rating apply to Anthropic’s stock?
No. Credit ratings assess debt-related risk, not common stock. A possible rating would concern borrowing, not serve as a direct rating of shares in the planned IPO.
Why is Blackstone’s forecast news if it is not an official rating?
Blackstone is a major lender in the reported $63 billion chip-financing deal. Its reported change in expectations may inform how investors view Anthropic’s borrowing risks, but it remains a forecast rather than an agency decision.
Could this mean Claude service will be interrupted?
The report does not establish any coming interruption or change to Claude. A rating could affect financing conditions, but the source material provides no evidence of an imminent service disruption.
