TL;DR
The Financial Times reported that Blackstone expects Anthropic to receive a high speculative-grade, or “junk,” rating after its planned IPO. That is an investor forecast, not a rating agency decision; Anthropic’s registration filing confirms it has not yet obtained investment-grade ratings from two major agencies. The IPO is filed but not priced, and the timing and eventual rating remain unknown.
Blackstone reportedly expects Anthropic to receive a high speculative-grade, or “junk,” credit rating after its planned stock market debut, according to a Financial Times report published October 30. The forecast is not an agency rating: Moody’s, S&P and Fitch have not announced a rating, while Anthropic’s IPO remains unpriced and without a set listing date.
The Financial Times reported that Blackstone, a major lender to Anthropic, told investors in a $63 billion chip-financing deal that it now expects the AI company to receive a rating in the double-B range after its IPO. TechCrunch summarized the report the same day. The Financial Times article is paywalled, and the details here reflect the available summary rather than a review of the full report.
According to TechCrunch’s summary, Blackstone had previously expected Anthropic to reach investment grade before 2027. TechCrunch sought comment from Anthropic and Blackstone, and both declined to comment. The reported change is therefore an attributed forecast from one investor, not a public decision by a credit-rating agency.
Anthropic’s October 26 registration statement confirms that a new $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 reported $6.2 billion in debt as of June 30, all in convertible notes held by Amazon. These disclosures do not establish what rating the agencies will assign.
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 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 the Rating Could Affect Borrowing
A credit rating concerns the risk of lending to a company; it is not a judgment on its stock or a prediction that it will default. The U.S. Securities and Exchange Commission says ratings apply to debt securities, not common shares, and describe an agency’s assessment of credit risk. A double-B rating is below the investment-grade threshold, which generally begins at BBB-minus, and falls in the speculative-grade category.
If Anthropic receives a below-investment-grade rating, it could face higher borrowing costs or different financing terms than an investment-grade borrower. The implications would depend on the agency decisions, the terms of its debt and how lenders respond. A rating does not, by itself, show that Anthropic cannot meet its obligations, and it does not determine whether Claude services will remain available.
The question matters because Anthropic is seeking public investors while relying on substantial financing for computing capacity. Companies that buy its products may want to monitor prices, contract terms and reliance on the service, but the reported forecast alone is not evidence of an immediate operational change.

IPO Filing and Financing Commitments
Anthropic filed its registration statement on October 26 and plans to list on Nasdaq under the symbol “ANT.” The filing has not set the share count, price range or debut date. A filing is an important step toward an IPO, but it does not mean shares are already priced or trading.
The financing at the center of the report is structured through a special-purpose vehicle that will buy Broadcom accelerators and networking equipment and lease it to Anthropic, according to a joint announcement dated October 26. Blackstone is identified in that announcement as the sole provider of the committed portion of the second-lien financing, a loan position that ranks behind senior debt. Broadcom’s filing says it provides residual-value support of up to about $43 billion.
Anthropic’s filing also reports $16.3 billion in revenue in the first half of 2026 and positive operating cash flow over that period. At the same time, the company lists large computing commitments. The source article estimates those contracts total about $637 billion, adding figures from the filing; it says many payments are due regardless of actual usage. That sum is the author’s calculation, not a rating-agency estimate, and it should not be treated as equivalent to debt currently outstanding.
“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 Decisions Remain Pending
No public rating from Moody’s, S&P or Fitch was identified in the source material, and none has confirmed Blackstone’s reported expectation. The agencies’ eventual assessments, the timing of any decisions and whether they will differ from one another are unknown. Blackstone and Anthropic have not publicly commented on the forecast, according to TechCrunch.
The IPO’s price range, share count and listing date are also unsettled. Although the filing provides financial results and financing terms, it does not establish how public-market investors will value Anthropic or what borrowing costs the company will face after listing. The reported forecast should not be confused with a downgrade of an existing published rating.
Watch for Ratings and IPO Terms
The next public milestones are updates to Anthropic’s IPO registration, including any eventual price range and share count, and any rating announcements from Moody’s, S&P or Fitch. Those developments would clarify the company’s planned market debut and whether it meets the rating condition attached to the credit line.
Until then, Blackstone’s reported view remains a forecast. Investors and business customers can distinguish that claim from information in Anthropic’s filings: reported revenue, debt, financing arrangements and stated computing commitments. Any assessment of the company’s ability to borrow or its effect on customers will depend on disclosures and decisions that have not yet been made public.
Key Questions
Has Anthropic officially received a junk credit rating?
No rating from Moody’s, S&P or Fitch is identified in the source material. The double-B expectation is attributed to Blackstone in a Financial Times report summarized by TechCrunch.
What does a double-B rating mean?
Double-B is below investment grade and is generally classed as speculative grade. It indicates an agency sees greater credit risk than for investment-grade debt; it is not a declaration of default.
No. Credit ratings concern debt, not common stock, according to the SEC. The rating would address lending risk, not directly assess the value or performance of Anthropic shares.
When will Anthropic’s IPO take place?
No date or price range has been set in the information provided. Anthropic filed its registration statement on October 26, 2026, and plans to list on Nasdaq under the symbol “ANT.”
