TL;DR
The Financial Times reported that Blackstone expects Anthropic to receive a double-B, non-investment-grade rating after its planned IPO. That is one lender’s forecast, not a rating-agency decision: Anthropic’s IPO is filed but not priced, and its registration statement describes a credit line that remains in place until the company earns investment-grade ratings from at least two major agencies.
Blackstone reportedly expects Anthropic to receive a double-B credit rating—a speculative-grade rating often called “junk”—after the AI company’s planned stock market debut, according to a Financial Times report summarized by TechCrunch on October 30. No major credit-rating agency has published such a rating, and the forecast is not a finding that Anthropic cannot repay its debts.
The report marks a change in Blackstone’s stated outlook. TechCrunch’s summary of the Financial Times article says Blackstone, described as the anchor investor in a $63 billion chip-financing deal, previously expected Anthropic to reach investment grade before 2027. Blackstone now reportedly anticipates a rating in the double-B range, the highest tier below investment grade. The Financial Times article is paywalled, and Blackstone and Anthropic declined to comment to TechCrunch.
The public filings provide relevant financial context but do not confirm Blackstone’s prediction. Anthropic’s October 26 registration statement says a $15 billion credit line is secured by substantially all of its assets until it obtains investment-grade ratings from at least two of Moody’s, S&P and Fitch. It reported $6.2 billion in debt as of June 30, consisting of convertible notes held by Amazon. The filing also reports first-half 2026 revenue of $16.3 billion and positive cash from operations.
The financing structure is documented separately. A joint announcement says a special-purpose vehicle will buy Broadcom accelerators and networking equipment and lease them to Anthropic. Blackstone is the sole provider of the committed portion of the deal’s second-lien financing, which ranks behind senior loans. Broadcom’s filing describes up to about $43 billion in residual-value support. The registration statement also lists large compute commitments; the source article calculates their total at about $637 billion, while noting that many payments are due regardless of actual usage.
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 Double-B Rating Could Mean
A double-B rating would describe the perceived risk of lending to Anthropic, not the quality or future price of its shares. The U.S. Securities and Exchange Commission explains that credit ratings apply to debt, not common stock. Ratings are opinions about repayment risk, not guarantees or predictions of immediate default. A speculative-grade rating can mean lenders demand higher borrowing costs or impose different terms, although the actual effect would depend on the rating, agreements and market conditions.
For companies and customers that rely on Claude, a rating on its own does not establish that service will be interrupted or prices will rise. The practical issue is whether financing costs and large, long-term computing commitments affect Anthropic’s capacity to invest, negotiate infrastructure contracts or sustain its services. Those consequences are possibilities, not outcomes confirmed by the report. The contrast between rapid revenue growth and a reported junk-rating forecast shows that lenders also weigh debt, fixed obligations and the durability of future cash flows.

IPO Filing and Credit Agreements
Anthropic filed its registration statement on October 26, 2026, and plans to list on Nasdaq under the symbol “ANT.” The filing is not a completed offering: the share count, price range and listing date had not been set in the source material. The company’s own filing describes the conditions attached to its $15 billion credit line, but does not announce a rating from Moody’s, S&P or Fitch.
In the standard framework described by the SEC, ratings of BBB-minus or higher are investment grade; ratings below that threshold, including double-B, are speculative grade. “Junk” is an informal market term for non-investment-grade debt. The category signals greater perceived credit risk, not that a company is insolvent. Credit ratings can change, and an agency’s assessment is distinct from an investor’s forecast. The Blackstone view reported by the Financial Times should therefore not be treated as an agency decision.
““substantially all” of its assets”
— Anthropic’s registration statement
Rating Decision Still Pending
No decision from Moody’s, S&P or Fitch appears in the supplied material, and the timing of any agency review is not stated. Blackstone and Anthropic declined to comment when TechCrunch asked about the report. The underlying Financial Times article is paywalled, so the details available here rely on TechCrunch’s account of it.
It is also unclear whether the reported expectation applies to a specific debt instrument or to Anthropic’s credit profile more broadly, and what assumptions Blackstone used. The IPO’s price range, share count and date remain unset in the source material. The reported forecast does not establish that Anthropic will receive a double-B rating, nor does it establish what borrowing costs or operating effects would follow.
Agency Ratings and IPO Terms
The next concrete developments to watch are any published assessments from Moody’s, S&P or Fitch, changes to Anthropic’s credit arrangements, and amendments or updates to its IPO registration statement. The company will also need to set offering terms before its planned Nasdaq listing can proceed. Until agencies issue ratings or Anthropic provides further detail, Blackstone’s reported view remains a forecast rather than a confirmed outcome.
Key Questions
Has Anthropic been given a junk credit rating?
No rating from Moody’s, S&P or Fitch is identified in the source material. The Financial Times report, as summarized by TechCrunch, says Blackstone expects a double-B rating after the IPO; that is an investor forecast, not an agency decision.
What does a double-B rating mean?
Double-B is a speculative-grade credit category, below the investment-grade threshold of BBB-minus. It indicates a rating agency sees greater repayment risk than for investment-grade debt; it does not mean default is certain or imminent.
No. Credit ratings assess debt and repayment risk, not the value or quality of common stock. Investors may consider many other factors when assessing an IPO.
Has Anthropic completed its IPO?
No. Anthropic filed a registration statement on October 26, 2026, but the source material says the share count, price range and listing date had not been set.
Could a junk rating affect Claude users?
There is no confirmed user impact in the report. A lower credit rating could affect borrowing terms, but whether that would change Claude’s price, availability or service is unknown.
