TL;DR

Anthropic filed to list on Nasdaq as “ANT,” but its share price, offering size and listing date have not been set. The Financial Times, as summarized by TechCrunch, reported that lender Blackstone expects Anthropic to receive a double-B speculative rating after the IPO; no Moody’s, S&P or Fitch rating has been announced.

Anthropic has filed to go public, but it has not yet received an investment-grade rating from two major credit agencies, according to its registration statement. Separately, the Financial Times reported that lender Blackstone expects a double-B rating after the IPO; that is an investor’s forecast, not a rating issued by Moody’s, S&P or Fitch.

Anthropic filed its registration statement on October 26 and plans to list on Nasdaq under the ticker ANT. The filing does not set a share price, price range, number of shares or trading date. It also says 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 rating forecast comes from a Financial Times report published October 30 and summarized by TechCrunch. According to TechCrunch’s account, Blackstone told investors in a $63 billion chip-financing deal that it now expects Anthropic to receive a high speculative-grade rating in the double-B range following its IPO. The outlet reported that Blackstone had previously expected investment grade before 2027. Anthropic and Blackstone declined to comment to TechCrunch.

The company’s filing reports $6.2 billion in debt as of June 30, all in convertible notes held by Amazon. A joint announcement says the $63 billion financing is structured through a special-purpose vehicle that will buy Broadcom accelerators and networking equipment and lease them to Anthropic. Blackstone is the sole provider of the committed portion of the second-lien financing, which ranks behind senior loans. Broadcom disclosed residual-value support of up to about $43 billion.

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.

Confirmed

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
Reported only

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
Not known

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 the Rating Could Affect Financing

A credit rating concerns the risk of lending to Anthropic, not the value or quality of its shares. The U.S. Securities and Exchange Commission describes ratings as opinions about the credit risk of debt securities. The commonly used boundary is between BBB-minus and BB-plus: BBB-minus and above is investment grade, while BB-plus and below is speculative grade, often called “junk” or “high yield.” Double-B is the highest tier below investment grade.

A speculative rating does not mean a borrower is bankrupt or about to default. It can, however, mean lenders view repayment as riskier and may demand higher returns or impose tighter terms. For a company financing expensive computing infrastructure, the difference can affect borrowing costs and the terms available for future projects. The filing’s asset-backed credit line makes the rating threshold relevant to Anthropic’s financing arrangements, though the precise consequences depend on the agreements and any eventual ratings.

The reported forecast also highlights a tension in Anthropic’s financial profile, rather than resolving it. The source says the filing reports $16.3 billion in first-half 2026 revenue and positive cash from operations. At the same time, it identifies substantial computing commitments, many payable regardless of actual usage. The source’s author estimates those named contracts total about $637 billion, but that is a calculation, not a figure stated as such in the filing. Revenue growth and cash generation do not by themselves settle how rating agencies will assess long-term obligations and debt repayment.

Filing and Financing Details

Anthropic’s registration statement is a filing for a proposed public offering, not proof that the IPO has been completed. It identifies the planned Nasdaq ticker as ANT, while the share count, price range and date remain unset. Those details are normally provided as the offering process advances; the material supplied here does not give a timetable for when that will happen.

The financing and ratings reports also refer to different things. The $63 billion chip deal is a financing arrangement involving equipment purchases and leases, not a statement that Anthropic has borrowed that entire amount as ordinary corporate debt. Blackstone’s role is described as providing the committed second-lien portion. The company’s reported $6.2 billion of debt at June 30, by contrast, consists of convertible notes held by Amazon, according to the filing.

For rating terminology, the SEC says agencies assess the credit risk of debt and that ratings are opinions that can change. A rating assigned by an agency is distinct from an investor’s view about what the agency may decide. The available source material identifies no public Moody’s, S&P or Fitch decision on Anthropic.

No Agency Rating Yet

No published rating from Moody’s, S&P or Fitch is identified in the available material, and the agencies’ eventual decisions and timing are unknown. Blackstone’s reported expectation is attributed to the Financial Times through TechCrunch; the Financial Times article was not available in full to the source writer. The expectation should not be presented as a confirmed rating or as a decision agreed by the agencies.

Anthropic and Blackstone declined to comment to TechCrunch, according to that outlet. The source also notes earlier reporting about ratings from smaller agencies on parts of Anthropic’s debt, but does not provide enough accessible detail to verify or explain those assessments. It remains unclear how any agency would weigh the company’s revenue, cash flow, debt, financing structure and future computing commitments, or whether its rating would change after the IPO.

The IPO itself is also incomplete: the filing does not specify the offering price, share count or date. The supplied figures on revenue, operating cash flow, debt and financing describe particular periods or arrangements; they do not establish future results or the terms of the eventual public offering.

IPO Terms and Rating Decisions

Investors will need to watch for an updated IPO prospectus with the offering’s share count and price range, as well as a confirmed listing date. Those details would clarify the proposed transaction but would not, on their own, settle the credit-rating question.

The next clear development on ratings would be a published decision or statement from Moody’s, S&P or Fitch. Until then, Blackstone’s reported double-B expectation remains a forecast. Anthropic’s credit-line terms, the financing structure for its computing equipment and any future agency assessments will determine how the company’s borrowing position is described as the IPO process proceeds.

Key Questions

Has Anthropic received a junk credit rating?

No agency rating is identified in the available material. The double-B rating is what Blackstone reportedly expects, not a rating issued by Moody’s, S&P or Fitch.

What has Anthropic confirmed about its IPO?

Anthropic filed a registration statement on October 26, 2026, and plans to list on Nasdaq as “ANT.” The filing does not set the share price, number of shares or listing date.

What does a double-B rating mean?

Double-B is a speculative-grade rating category below investment grade. It signals an agency’s view of debt risk; it does not mean the company has defaulted, and it is not a rating of its shares.

Who reported the expected rating?

The Financial Times reported Blackstone’s expectation on October 30, and TechCrunch summarized the report. TechCrunch said both Blackstone and Anthropic declined to comment.

Why does the rating matter if Anthropic is growing?

Ratings can affect the cost and terms of borrowing. Revenue growth and positive operating cash flow are relevant, but lenders and rating agencies also assess debt, repayment risk and long-term financial commitments.
