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 an investor forecast, not a rating decision: Anthropic has not announced an IPO price or date, and no rating from Moody’s, S&P or Fitch was identified in the source material.
Blackstone reportedly expects Anthropic to receive a high-yield, double-B credit rating after its planned stock-market debut, according to a Financial Times report summarized by TechCrunch. The forecast matters because it points to a possible gap between the AI company’s rapid growth and how lenders assess its ability to meet large, long-term financial commitments; no major rating agency has announced a rating.
According to TechCrunch’s account of the Financial Times report, Blackstone told investors in a $63 billion chip-financing deal that Anthropic could receive a rating in the double-B range after its IPO. That is the highest tier below investment grade. Blackstone had previously expected Anthropic to reach investment grade before 2027, the reports said. The Financial Times article was published October 30; the source material says it is behind a paywall and that TechCrunch summarized it the same evening.
Anthropic and Blackstone declined to comment when approached by TechCrunch. The source material identifies no public rating from Moody’s, S&P or Fitch and no confirmation from those agencies. The reported forecast therefore describes Blackstone’s expectation, not a decision by a credit-rating agency. TechCrunch characterized the forecast as a prediction.
Anthropic’s October 26 registration statement confirms the company had $6.2 billion in debt as of June 30, all in convertible notes held by Amazon. It also describes a $15 billion credit line secured by substantially all of Anthropic’s assets until the company receives investment-grade ratings from at least two of Moody’s, S&P and Fitch. The IPO filing names Nasdaq and the proposed ticker ANT, but the share count, price range and listing date had not been set in the source material.
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

How a Rating Could Affect Anthropic
A credit rating measures the perceived risk of a borrower’s debt; it is not an assessment of the company’s shares or a prediction that it will fail. The SEC explains that ratings below BBB-minus are generally classified as non-investment grade, also called speculative or high yield. Double-B sits just below investment grade, so a rating in that range would signal greater perceived lending risk, not a default.
For a company raising money to support large computing needs, the distinction can affect financing terms. Lower-rated borrowers may face higher borrowing costs or a narrower pool of lenders, although the actual effect would depend on the rating, market conditions and the terms of any borrowing. Anthropic’s credit agreement ties the release of collateral to investment-grade ratings from two agencies, making its rating path relevant to its financing arrangements as well as its reputation with investors.
For customers and employees, the reported expectation is not evidence of an immediate change to Claude or a service interruption. The practical concern is indirect: the cost and availability of capital could shape how Anthropic funds computing capacity and other commitments. The filing documents substantial obligations, but the available information does not establish that the company cannot meet them or that customers will see changes.

IPO Filing and Financing Commitments
Anthropic filed its registration statement on October 26, 2026, with plans to list on Nasdaq under the symbol ANT. A filing is a step toward a public offering, not a completed IPO: the source material says no share count, price range or listing date had been announced. It also does not establish that the offering would itself trigger a rating decision.
The same day, a joint press release described a $63 billion financing arrangement involving a newly formed special-purpose vehicle. The vehicle is set to buy Broadcom accelerators and networking equipment and lease them to Anthropic. The release identified Blackstone as the sole provider of the committed portion of the second-lien financing, which ranks behind senior loans. A Broadcom filing said the company would provide residual-value support of up to about $43 billion.
Anthropic’s filing reports $16.3 billion in revenue in the first half of 2026 and positive cash from operations for that period. At the same time, the source article calculated that named computing contracts total about $637 billion and said many are payable regardless of actual usage. That sum is the article author’s calculation from the filing, not a company-reported total. The figures show why strong recent growth does not, by itself, settle how lenders view longer-term obligations.
“Credit ratings “apply to debt securities” and “do not apply to equity securities like common stock.””
— U.S. Securities and Exchange Commission, investor bulletin on credit ratings
Rating Decision and IPO Terms Remain Open
No rating agency decision is confirmed in the available source material. It is not clear whether Moody’s, S&P or Fitch will rate Anthropic after the IPO, what rating any agency might assign, or when it would do so. Blackstone’s forecast was reported secondhand through the Financial Times and TechCrunch; both Blackstone and Anthropic declined to comment.
The IPO’s share count, offering price and date were also not set in the source material. Nor does the reported forecast show what borrowing costs Anthropic would face, whether its credit terms would change, or whether the forecast reflects a complete view of the company’s finances. Ratings can change as agencies assess a borrower’s finances and risks.
Watch for Agency Ratings and IPO Details
The next clear milestones are further filings or announcements that establish the IPO timetable and offering terms, along with any public rating actions by Moody’s, S&P or Fitch. Those decisions would clarify whether Blackstone’s reported expectation is shared by rating agencies and whether Anthropic meets the investment-grade condition described in its credit agreement.
Until then, the reported double-B outlook should be treated as one lender’s forecast, not a final judgment on Anthropic’s creditworthiness or a signal that its services are about to change. Investors and customers can distinguish the confirmed filing and financing terms from the still-unknown rating outcome.
Key Questions
Has Anthropic received a junk credit rating?
No rating is confirmed in the source material. The report says Blackstone expects a double-B rating after Anthropic’s planned IPO; it does not report a published decision from Moody’s, S&P or Fitch.
What does a double-B rating mean?
Double-B is generally a non-investment-grade, high-yield category, below the investment-grade threshold of BBB-minus. It indicates greater perceived lending risk, not that a borrower has defaulted.
No. The SEC says credit ratings apply to debt securities, not common stock. A credit rating would concern the perceived risk of lending to Anthropic, not the value or prospects of its shares.
When will Anthropic go public?
Anthropic filed a registration statement on October 26, 2026, and named Nasdaq and the proposed ticker ANT. The source material says the offering price range, share count and listing date had not been set.
Does the reported forecast mean Claude services will change?
There is no confirmed service change tied to Blackstone’s reported forecast. Any effects would depend on financing and business decisions that have not been announced in the source material.
