TL;DR
The Financial Times reported that Blackstone expects Anthropic to receive a high-yield, double-B credit rating after its planned public listing, a shift from its earlier expectation of investment grade before 2027. That is one investor’s forecast, not a rating-agency decision: Anthropic has filed to go public, but its share price and listing date are not set, and no Moody’s, S&P or Fitch rating has been announced.
The Financial Times reported on October 30 that Blackstone expects Anthropic to receive a high-yield, double-B credit rating after the Claude maker’s planned stock market debut, rather than the investment-grade rating Blackstone had previously expected before 2027. The forecast is not an official rating: Anthropic has filed for an IPO, but its offering terms are unset, and Moody’s, S&P and Fitch have not announced a rating.
According to TechCrunch’s summary of the Financial Times report, Blackstone shared its revised expectation with investors in a $63 billion chip-financing deal for Anthropic. Blackstone is described in the deal materials as the sole provider of the committed portion of the second-lien financing, a layer that ranks behind senior loans. The Financial Times report is behind a paywall, and Blackstone and Anthropic declined to comment when TechCrunch asked about it.
The company’s October 26 registration statement confirms a separate, important point: an approximately $15 billion 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. The filing does not say that those agencies have rated Anthropic. It reports $6.2 billion in debt as of June 30, all in convertible notes held by Amazon.
Anthropic reported $16.3 billion in revenue for the first half of 2026 and positive operating cash flow for the period. At the same time, contracts for computing capacity disclosed in the filing total about $637 billion, according to the source article’s calculation; many payments are due regardless of actual usage. That amount is a sum of commitments, not a measure of current debt or an annual bill. The filing was submitted on October 26, and Anthropic plans to list on Nasdaq under the symbol ANT, but it has not set a share price, the number of shares offered or the listing date.
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 Credit Costs Could Rise
A credit rating concerns the risk of lending to a company, not whether its shares are a good investment or whether its product works. The U.S. Securities and Exchange Commission says ratings apply to debt securities, not common stock, and reflect an agency’s assessment rather than a guarantee of repayment. A double-B rating sits below the investment-grade threshold and is commonly described as speculative grade or high yield.
If a rating agency eventually assigns Anthropic a speculative-grade rating, lenders could demand higher interest or other protections to compensate for perceived credit risk. The actual effect would depend on the rating, financing terms and market conditions; Blackstone’s reported forecast alone does not establish that borrowing costs have changed. A rating could also affect how investors assess the company’s ability to fund its computing commitments alongside its growth.
For customers and business partners, the immediate point is not that the company is insolvent or that Claude service is about to stop. A rating is about debt repayment, and the filing records substantial revenue as well as large obligations. The practical issues to monitor are pricing, service terms and reliance on a single provider as the company raises capital and finances computing capacity.

IPO Filing and Financing Structure
The reported forecast comes amid Anthropic’s preparations for a public offering. Its October 26 S-1 registration statement describes the company’s finances, risks and proposed Nasdaq listing, but filing is not the same as completing an IPO. The share count, price range and date have not been announced in the supplied material.
The $63 billion chip financing is structured through a newly formed special-purpose vehicle that buys Broadcom accelerators and networking equipment and leases them to Anthropic, according to the parties’ October 26 announcement. Blackstone provides the committed second-lien portion. A Broadcom filing says the company provides residual-value support of up to about $43 billion for the transaction. Those details describe the financing arrangement; they do not confirm Blackstone’s reported rating forecast.
The terms “investment grade” and “junk” refer to positions on a debt-rating scale. The SEC describes the dividing line as between BBB and BB categories: BBB-minus or higher is generally investment grade, while ratings below it are non-investment grade, speculative or high yield. Double-B is below that threshold, but it is not itself a declaration of default. Ratings are agency opinions and can change as circumstances and assessments change.
“Credit ratings apply to debt securities.”
— The U.S. Securities and Exchange Commission, in its investor bulletin on credit ratings
No Agency Rating Yet
The key unresolved issue is whether Moody’s, S&P or Fitch will rate Anthropic after its IPO, and what rating each agency would assign. No rating from those agencies is identified in the supplied material. Blackstone’s expectation, as reported by the Financial Times and summarized by TechCrunch, should not be treated as a decision by any agency.
The Financial Times article was not available in full to the source writer, and the details of Blackstone’s investor communication have not been independently established here. Both Blackstone and Anthropic declined to comment to TechCrunch. The reasons for Blackstone’s reported change in outlook, and whether it reflects new financial analysis or other considerations, remain unclear.
The IPO itself also remains in an early stage. The registration statement has been filed, but price, share count and timing are not set in the available information. The total value of disclosed computing contracts is a calculated sum, not a confirmed debt balance; the precise timing and cash-flow effect of the commitments are also not detailed here.
Watch the IPO and Rating Process
Investors and customers can watch for an amended registration statement, which may provide more information about the offering, and for Anthropic to announce its share price, share count and listing date. Until those terms are published, the IPO’s valuation and scale cannot be assessed from the filing alone.
A separate milestone is any rating announcement from Moody’s, S&P or Fitch. The credit-line condition described in Anthropic’s filing depends on investment-grade ratings from at least two of the three agencies. Whether and when that condition is met, and whether the rating process changes financing terms, are not yet known.
For now, the confirmed picture combines rapid revenue growth, positive operating cash flow in the first half of 2026, reported debt and significant computing commitments. Blackstone’s forecast adds a signal about how one lender may view the company’s credit risk, but it does not settle the rating question. The next meaningful evidence will come from the IPO documents, agency decisions and disclosed financing terms.
Key Questions
Has Anthropic received a junk credit rating?
Not according to the supplied information. The Financial Times report describes Blackstone’s expectation; no rating from Moody’s, S&P or Fitch has been announced.
What does a double-B rating mean?
Double-B is below the usual investment-grade threshold and is generally classed as speculative grade or high yield. It signals an agency’s assessment of debt risk, not a prediction that default is certain.
Does the reported rating concern Anthropic stock?
No. Credit ratings assess debt securities and repayment risk, not common shares. The report concerns expected borrowing credit quality after the planned IPO.
When will Anthropic go public, and at what price?
Anthropic filed a registration statement and plans to list on Nasdaq as ANT, but the supplied information gives no share price, offering size or listing date.
Why might lenders view Anthropic as risky despite its growth?
The company reported strong revenue and positive operating cash flow, but its filing also describes substantial computing commitments, many payable regardless of usage. How lenders weigh those obligations against growth and cash generation is not established by the reported forecast.
