TL;DR
The Financial Times reported that Blackstone expects Anthropic to receive a double-B, below-investment-grade rating after its planned IPO, revising an earlier expectation. That is a forecast attributed to one lender, not a published rating: Anthropic has filed to go public, but its share price, offering size and credit-agency decisions remain unknown.
Blackstone reportedly expects Anthropic, the maker of Claude, to receive a double-B credit rating—below investment grade—after its planned stock-market debut, according to a Financial Times report published October 30. The prediction is not a rating decision: no public rating from Moody’s, S&P or Fitch is identified in the available information, and Anthropic has not yet priced its proposed IPO.
The Financial Times report, summarized by TechCrunch, says Blackstone told investors in a $63 billion chip-financing deal that it now expects Anthropic to receive a high speculative-grade rating in the double-B range after an IPO. The report also says Blackstone previously expected the company to reach investment grade before 2027. Blackstone and Anthropic declined to comment when approached by TechCrunch, according to that outlet. The Financial Times article is behind a paywall, and the underlying investor communication is not included in the available source material.
Anthropic’s October 26 registration statement confirms that the company has filed for a Nasdaq listing under the proposed symbol ANT. It does not set a share count, price range or listing date. The filing also describes a $15 billion credit line whose terms tie certain conditions to the company obtaining investment-grade ratings from at least two of Moody’s, S&P and Fitch. The filing therefore documents a ratings threshold relevant to financing, but does not confirm Blackstone’s reported forecast.
The filing reports $6.2 billion in debt as of June 30, consisting of convertible notes held by Amazon, and revenue of $16.3 billion in the first half of 2026. The source material also reports positive operating cash flow in that period. Separately, it calculates that listed compute commitments total about $637 billion, with many payments due regardless of actual usage. That figure is the source author’s sum of commitments, not a company-reported total presented as such.
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
- Earlier, Blackstone expected investment grade before 2027
- Anthropic and Blackstone declined to comment
Still open
- What Moody’s, S&P and Fitch will decide, and when
- The IPO price, size and date
- The total in the S-1’s commitments table, still blank
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

What a Lower Rating Could Affect
A below-investment-grade rating would describe lenders’ assessment of Anthropic’s debt risk, not the quality of Claude or the value of the company’s shares. The U.S. Securities and Exchange Commission says credit ratings apply to debt securities rather than common stock. Ratings are opinions about credit risk, not guarantees that a borrower will default or repay.
If a major agency eventually assigns a speculative-grade rating, lenders and investors could treat borrowing as riskier and seek higher interest or other protections. The effect would depend on the rating, the terms of specific facilities and market conditions; the report alone does not establish that Anthropic’s financing costs have changed. The credit-line language in the filing makes the rating milestone relevant to the company’s financing, but the available material does not spell out every consequence of reaching or missing it.
For business customers and users, a rating forecast is not evidence of an imminent interruption to Claude. The more direct questions are whether financing conditions affect the company’s capacity to fund computing infrastructure, and whether costs or customer terms change. No service disruption or customer-price change is reported in the source material.

The IPO and Chip-Financing Structure
Anthropic filed its registration statement on October 26, 2026, beginning the public disclosure process for a potential Nasdaq listing. Filing does not mean the offering is complete: the company has not set the price, number of shares or date in the information provided here. A credit rating after a listing would be a separate judgment about its ability to meet debt obligations.
The same day, a joint announcement described the $63 billion financing arrangement as involving a newly formed special-purpose vehicle that buys Broadcom accelerators and networking equipment and leases them to Anthropic. Blackstone is identified in the announcement as the sole provider of the committed portion of the second-lien financing, which ranks behind senior debt. Broadcom’s October 26 filing says it will provide residual-value support of up to about $43 billion. These terms show the scale and structure of the infrastructure financing; they do not establish that the arrangement will produce a particular credit rating.
In standard U.S. rating terminology, BBB-minus or higher is generally investment grade, while BB-level ratings fall below that threshold. “Junk” is a colloquial term for speculative-grade or high-yield debt. A double-B rating is below investment grade, but it is not the same as a default declaration. The SEC cautions that ratings are agency opinions and can change.
“Credit ratings apply to debt securities.”

No Agency Rating Has Been Published
The main unresolved point is whether Moody’s, S&P or Fitch will rate Anthropic after its IPO, what rating any agency would assign, and when it would do so. The source material identifies no public decision from those agencies. It also does not provide Blackstone’s underlying investor communication, and TechCrunch’s account is a summary of a Financial Times article that the source author says they could not read in full.
The reported double-B outlook should therefore remain attributed to Blackstone, as reported by the Financial Times. The available information does not establish why the lender changed its expectation, whether all relevant lenders share that view, or how rating agencies would weigh Anthropic’s revenue growth, cash flow, debt and long-term computing commitments. Nor does it establish the final terms or timing of the IPO.
Watch the Filing and Rating Decisions
The next public milestones are the development of Anthropic’s IPO filing, including any eventual share-price range, share count and listing schedule, and any rating announcements from Moody’s, S&P or Fitch. Those decisions could clarify how agencies assess the company’s growth, debt and infrastructure commitments. Until an agency issues a rating, the double-B expectation remains a reported forecast rather than a confirmed credit grade.
Investors and customers can also watch for changes to financing disclosures, borrowing terms and customer plans. The material available so far does not report a change in Claude pricing or service availability, so any such effects remain possible outcomes to monitor, not established developments.
Key Questions
Has Anthropic been given a junk credit rating?
No published rating from Moody’s, S&P or Fitch is identified in the available information. The double-B outlook is attributed to Blackstone in a Financial Times report summarized by TechCrunch.
What does a double-B rating mean?
A double-B rating is below investment grade in standard U.S. rating categories. It indicates an agency views debt as more speculative than investment-grade debt; it does not mean the borrower has defaulted.
Does the reported rating concern Anthropic shares?
No. A credit rating assesses debt and repayment risk, not the value or quality of common shares. The proposed IPO remains a separate process, and its price and share count have not been set in the information provided.
When is Anthropic’s IPO expected?
Anthropic filed a registration statement on October 26, 2026, proposing a Nasdaq listing under the symbol ANT. No listing date or price range is specified in the source material.
Does this report mean Claude service will be interrupted?
No service interruption is reported. A lender’s reported rating expectation does not by itself establish a change to Claude’s availability, pricing or customer terms.
