TL;DR
The Financial Times reported that Blackstone expects Anthropic to receive a high-yield, double-B credit rating after its planned IPO, reversing an earlier expectation of investment grade before 2027. This is one investor’s forecast, not a published rating: Anthropic’s IPO filing confirms it does not yet have investment-grade ratings from two major agencies, and the eventual rating remains unknown.
Blackstone reportedly expects Anthropic to receive a double-B, speculative-grade credit rating after its planned stock market debut, according to a Financial Times report published October 30. The forecast, summarized by TechCrunch, is not a rating-agency decision: Anthropic’s IPO filing confirms it does not yet have investment-grade ratings from two major agencies, while the eventual rating and timing remain unknown.
The Financial Times reported that Blackstone, a lender to Anthropic, told investors in a $63 billion chip-financing deal that it now expects the Claude maker to receive a “high” junk rating, in the double-B range, after its IPO. TechCrunch summarized the report. The article’s author said they could not read the FT report in full, and the account available here does not include a direct statement from Blackstone.
According to TechCrunch’s summary, Blackstone had previously expected Anthropic to reach investment grade before 2027. TechCrunch said it asked Anthropic and Blackstone for comment, and both declined. No published rating from Moody’s, S&P or Fitch is identified in the supplied material. The reported change is therefore an investor forecast, not confirmation of what any agency will decide.
Anthropic’s registration statement, filed October 26, says a $15 billion credit line is 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. The filing also reports $6.2 billion in debt as of June 30, all in convertible notes held by Amazon. The IPO is filed but not priced: the share count, price range and listing date have not been set. Anthropic plans to list on Nasdaq under the symbol “ANT.”
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

Why Lenders May See More Risk
A credit rating can affect the cost and availability of borrowing, even for a company with substantial cash and rapidly growing revenue. The source material reports $131.7 billion in cash and short-term investments, revenue of $16.3 billion in the first half of 2026, and positive operating cash flow in that period. Those figures do not settle how rating agencies will view the company’s longer-term ability to meet obligations.
The filing lists large commitments to computing infrastructure. The source’s author calculates that named compute contracts total about $637 billion, while noting that many payments are due regardless of actual usage. That total is the author’s sum, not a figure presented by the filing as a single liability. Large contractual commitments can matter to lenders because they may create fixed costs even if demand, revenue or technology needs change.
A double-B rating would be below the investment-grade threshold, but it would not mean Anthropic is bankrupt or that its shares have received a negative grade. Credit ratings assess debt repayment risk, not stock performance. For customers and businesses using Claude, the reported forecast does not itself signal an immediate service change; the more direct issues to watch are whether financing costs affect company decisions, prices or service terms.

The IPO and Financing Structure
Anthropic filed its registration statement on October 26, 2026, starting the public-listing process but not setting a share price or date. The same day, a joint announcement described a financing structure involving a newly formed special-purpose vehicle. It is to buy Broadcom accelerators and networking equipment and lease them to Anthropic.
The joint announcement identifies Blackstone as the sole provider of the committed portion of the deal’s second-lien financing, a layer that ranks behind senior loans. A Broadcom filing says the company provides residual-value support of up to about $43 billion. These disclosures describe the financing arrangement; they do not establish that Blackstone has received or issued a credit rating for Anthropic.
In general, investment grade begins at BBB-minus or equivalent, while ratings in the BB category fall below that line. The SEC describes credit ratings as assessments of debt securities and notes they do not apply to common stock. “Junk” is a market term for speculative-grade debt, not a synonym for default.
“The credit line is secured by “substantially all” of Anthropic’s assets until it obtains investment-grade ratings from at least two of Moody’s, S&P and Fitch.”

Agency Ratings Are Still Pending
No major-agency rating is reported in the source material, and the available information does not establish whether or when Moody’s, S&P or Fitch will rate Anthropic. The agencies could reach different conclusions, and a rating can change as circumstances and assessments develop. Blackstone’s forecast should not be treated as their decision.
The details behind the FT report cannot be independently established from the material provided: the article was paywalled, and TechCrunch’s summary is the account available here. Anthropic and Blackstone declined to comment, according to TechCrunch. The filing also does not specify the IPO’s price range, share count or listing date. The eventual effect of a rating on Anthropic’s borrowing costs, financing arrangements or customer pricing is not yet known.
Watch for Ratings and IPO Terms
The next confirmed milestones are the publication of IPO terms and any rating decisions or statements from Moody’s, S&P and Fitch. Anthropic’s registration statement has been filed, but investors do not yet have a price range, final share count or listing date in the supplied information.
Until an agency publishes a rating, the reported double-B expectation remains an attributed forecast. Any later rating should be read alongside the company’s debt, cash flows and infrastructure commitments; none alone determines the company’s stock value or guarantees its ability to meet future obligations.
Key Questions
Has Anthropic been given a junk credit rating?
No rating is confirmed. The Financial Times reported that Blackstone expects a double-B rating after Anthropic’s planned IPO. The source material identifies no published rating from Moody’s, S&P or Fitch.
What does a double-B rating mean?
A double-B rating is below investment grade and is commonly classed as speculative grade or high yield. It reflects an agency’s assessment of debt risk; it is not a statement that the borrower has defaulted.
Does the reported forecast grade Anthropic’s stock?
No. Credit ratings address debt repayment risk, not common-stock performance. The report concerns a possible rating for Anthropic’s borrowing, not a rating for its IPO shares.
When will Anthropic’s IPO take place?
The company filed its registration statement on October 26, 2026 and plans to list on Nasdaq as “ANT.” The available information does not set a listing date, share count or price range.
Could a lower rating affect Claude users?
The reported forecast does not establish any immediate change to Claude. Possible effects on financing costs or company decisions remain uncertain; users can monitor service terms, pricing and product announcements for confirmed changes.
