TL;DR
The Financial Times reported that Blackstone now expects Anthropic to receive a double-B, below-investment-grade rating after its planned IPO. That is an investor forecast, not a rating-agency decision; Anthropic’s filing confirms it has not yet met the investment-grade condition in a credit agreement. The IPO terms and any eventual ratings remain undecided.
The Financial Times reported on October 30 that Blackstone expects Anthropic to receive a double-B, below-investment-grade credit rating after its planned stock-market debut. The forecast, relayed by TechCrunch, is Blackstone’s expectation—not a rating issued by Moody’s, S&P or Fitch—and Anthropic’s IPO has not yet been priced.
According to TechCrunch’s summary of the Financial Times report, Blackstone told investors in a $63 billion chip-financing deal that it now expects Anthropic to receive a rating in the “high” junk range, specifically the double-B category. The reported expectation differs from Blackstone’s earlier view that Anthropic would reach investment grade before 2027. The Financial Times report is behind a paywall, and the full article was not available to the source writer.
Anthropic and Blackstone declined to comment when approached by TechCrunch. The source material says it found no published rating or statement from Moody’s, S&P or Fitch confirming Blackstone’s forecast. The prediction should not be described as an agency decision or as evidence that a downgrade has occurred.
Anthropic’s October 26 registration statement confirms the company does not yet have investment-grade ratings from at least two of those three agencies, a threshold referenced in its credit agreement. The filing also reports $6.2 billion in debt as of June 30, all in convertible notes held by Amazon. Separately, a joint announcement describes the $63 billion financing structure: Blackstone is the sole provider of the committed portion of its second-lien financing, which ranks behind senior loans.
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
- AA · Astrong
- 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

Why a Double-B Forecast Matters
A double-B rating is below investment grade, but it is not a declaration that a borrower is insolvent or about to default. Credit ratings express an agency’s assessment of debt repayment risk. A lower rating can affect the terms and cost of borrowing because lenders may demand greater compensation for taking on more risk.
The distinction matters because Anthropic is reporting rapid growth while also taking on large financing commitments. The source material cites $16.3 billion in revenue in the first half of 2026 and positive operating cash flow during that period. It also calculates roughly $637 billion in compute contracts listed in the filing, many of which may require payment regardless of actual usage. That total is the source writer’s sum, not a figure presented as such by Anthropic.
For customers and businesses using Claude, the reported forecast does not establish that the service will be interrupted or that prices will change. Its nearer relevance is financial: credit costs and contractual obligations can affect a company’s flexibility and spending choices. The available information does not show that any specific change to service, pricing or customer terms is planned.

IPO Filing and Financing Terms
Anthropic filed a registration statement on October 26, 2026, proposing a Nasdaq listing under the ticker “ANT.” According to the source material, the filing does not set a share count, price range or IPO date. The proposed listing is therefore a filed offering, not a completed public-market debut.
The filing’s credit agreement ties a $15 billion credit line to the company obtaining investment-grade ratings from at least two of Moody’s, S&P and Fitch. The agreement says substantially all of Anthropic’s assets secure the line until that rating condition is met. This confirms the contractual threshold; it does not establish what rating the agencies will assign or when they will do so.
The financing deal also involves equipment leasing. A joint press release says a newly formed special-purpose vehicle will buy Broadcom accelerators and networking equipment and lease them to Anthropic. A Broadcom filing describes up to about $43 billion in residual-value support. These financing details help explain why lenders may weigh long-term commitments alongside growth, but they do not independently confirm Blackstone’s reported rating forecast.
“The $15 billion credit line remains secured by “substantially all” of the company’s assets until it obtains investment-grade ratings from at least two of Moody’s, S&P and Fitch.”

Agency Ratings and IPO Terms
No rating from Moody’s, S&P or Fitch confirming the reported double-B expectation is identified in the source material. It is also unclear whether any of the agencies has begun or completed a public assessment, what ratings each might assign, or when an assessment could be published. Blackstone’s earlier expectation and its reported revision have not been independently confirmed by an agency.
The IPO remains subject to unanswered questions. The filing does not specify the share count, offering price range or listing date, and the eventual terms could change. Anthropic and Blackstone have not publicly explained the reported shift in Blackstone’s outlook. The source material also notes earlier Financial Times coverage of ratings from smaller agencies on portions of Anthropic’s debt but leaves those details out because the reports could not be reviewed directly.
Rating and Offering Milestones
The next concrete milestones are the publication of any formal rating decisions and updates to Anthropic’s IPO filing. Until an agency releases a rating, Blackstone’s reported view remains an investor forecast. Investors and other readers can also look for an amended registration statement setting out the offering’s share count, price range and timing.
Further disclosure about the financing structure, debt obligations and compute commitments may clarify how the company’s growth and spending obligations are being assessed. At present, the confirmed record supports a narrower conclusion: Anthropic has filed for an IPO and has not met the investment-grade condition stated in its credit agreement. Whether it receives a double-B rating—or any other rating—remains unresolved.
Key Questions
Has Anthropic officially received a junk credit rating?
No rating-agency decision is confirmed in the source material. The double-B rating is Blackstone’s expectation as reported by the Financial Times and summarized by TechCrunch.
What does a double-B rating mean?
Double-B is a speculative-grade rating below investment grade. It signals a higher assessed risk of debt repayment than investment-grade ratings; it is not, by itself, a finding that the borrower has defaulted.
Is Anthropic’s IPO complete?
No. Anthropic filed a registration statement on October 26, 2026, but the source material says the share count, price range and listing date have not been set.
Does the report mean Claude service or pricing will change?
No such change is confirmed. The report concerns a lender’s expectation about Anthropic’s credit rating. The available information does not announce an interruption, price change or new customer terms.
