TL;DR
The Financial Times reported that lender Blackstone now expects Anthropic to receive a high-yield, double-B credit rating after a stock market debut, rather than the investment-grade rating it previously expected before 2027. That is an investor forecast, not a rating-agency decision: Anthropic’s IPO filing confirms the company does not yet have investment-grade ratings from two major agencies, while its share price and listing date are still unknown.
Blackstone reportedly expects Anthropic to receive a high-yield, double-B credit rating after the Claude maker goes public, according to a Financial Times report published October 30 and summarized by TechCrunch. The forecast contrasts with Blackstone’s earlier expectation that Anthropic would reach investment grade before 2027, but no rating agency has announced a rating, and the company’s IPO is not yet priced or dated.
The report concerns Blackstone’s expectation, not a formal decision by Moody’s, S&P or Fitch. TechCrunch said Blackstone shared the forecast with investors in a $63 billion chip-financing deal, in which it is the sole provider of the committed portion of the second-lien financing. That financing ranks behind senior loans. The Financial Times report is behind a paywall, and the detailed forecast is available here through TechCrunch’s account of it.
Anthropic’s October 26 registration statement confirms it does not yet have investment-grade ratings from at least two of the three major agencies. The filing says a $15 billion credit line is secured by substantially all of the company’s assets until it obtains that threshold. It also reports $6.2 billion in debt as of June 30, all in convertible notes held by Amazon.
The IPO filing is a step toward a public listing, not a completed offering. Anthropic plans to list on Nasdaq under the symbol ANT, but has not set the number of shares, price range or listing date. Separately, the companies’ October 26 announcement describes a special-purpose vehicle that will buy Broadcom accelerators and networking equipment and lease them to Anthropic. Broadcom’s regulatory filing says it will provide up to about $43 billion in residual-value support for the arrangement.
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 the Rating Could Raise Costs
A below-investment-grade rating would concern the risk of lending to Anthropic, not the quality or future price of its shares. The SEC says credit ratings apply to debt securities, not common stock, and reflect an agency’s assessment of repayment risk. A double-B rating sits in the top tier below investment grade; it is not itself a declaration that a borrower is in default.
For borrowers, a lower rating can affect the terms and availability of financing. Lenders may seek higher interest to compensate for perceived risk, while existing credit arrangements can make ratings relevant to conditions or restrictions. In Anthropic’s case, the filing links its asset-secured credit line to attaining investment-grade ratings from two agencies. The precise consequences of any future rating would depend on the company’s agreements and the agencies’ decisions.
The tension is that Anthropic’s business is growing quickly while its spending commitments are substantial. Its filing reports $16.3 billion in first-half 2026 revenue and positive cash from operations. At the same time, the source’s calculation of commitments named in the filing totals about $637 billion; some payments are due regardless of actual usage. That total is a calculation of contractual commitments, not the same as debt already outstanding, and the obligations’ timing and conditions matter.

IPO Filing and Financing Structure
Anthropic filed its registration statement on October 26, 2026, beginning the public-offering process. The filing provides information about the company’s business, finances and risks, but it does not set the final share price or establish when trading will begin. Those details remain pending.
The financing story has several distinct pieces. Blackstone’s reported outlook relates to the $63 billion chip-financing arrangement, not to a rating already issued on Anthropic’s public shares. The joint announcement says a newly formed vehicle will acquire Broadcom equipment and lease it to Anthropic; Blackstone supplies the committed second-lien financing. Broadcom’s stated residual-value support is a separate feature of the structure.
“Investment grade” generally begins at BBB-minus on the standard scale described by the SEC; ratings below that line, including the double-B category, are called speculative grade or high yield. “Junk” is a blunt market term for below-investment-grade debt. The source material also notes reports about ratings from smaller agencies on parts of Anthropic’s debt, but does not provide enough accessible detail to establish those ratings here.
“The credit line is secured by “substantially all” of the company’s assets until it obtains an investment-grade rating from at least two of Moody’s, S&P and Fitch.”

Agency Decisions and IPO Terms
No major agency rating has been disclosed in the material available for this report. It is not known whether Moody’s, S&P or Fitch will assign Anthropic a rating, what level any rating would carry, or when a decision might come. Blackstone’s reported expectation should not be treated as confirmation of an agency outcome.
The Financial Times article could not be reviewed in full here; the reported forecast is based on TechCrunch’s summary. Blackstone and Anthropic declined to comment to TechCrunch. Anthropic has filed to go public, but it has not announced the offering’s share count, price range or date. The effect of any future credit rating on borrowing costs, financing access or contractual terms also remains uncertain.
There are limits to what the headline comparison shows. Strong revenue growth and positive operating cash flow are relevant financial facts, but they do not by themselves determine a credit rating. Nor should the roughly $637 billion estimate of named compute commitments be read as current debt: it is a sum of commitments, some payable regardless of usage, and the source does not give a single comparable maturity or payment schedule for that total.
Rating and Offering Milestones
The next concrete IPO milestones would be an amended or updated filing that sets out the offering’s terms, followed by a price range and a date for the share sale. Until those details are published, investors cannot assess the proposed valuation or the final size of the offering.
For the credit question, the key development would be a rating announcement from Moody’s, S&P or Fitch, or new company disclosures about debt and financing terms. Any eventual rating should be distinguished from Blackstone’s reported forecast and read alongside the agency’s stated rationale. The timing of those steps has not been announced.
Key Questions
Has Anthropic been given a junk rating?
No rating from Moody’s, S&P or Fitch is confirmed in the available source material. The double-B outlook is reported as Blackstone’s expectation, not an agency decision.
What does a double-B rating mean?
Double-B is below investment grade and is generally described as speculative grade or high yield. It indicates an assessment of debt repayment risk; it is not, by itself, a declaration of default.
Would a junk rating grade Anthropic’s stock?
No. The SEC says credit ratings apply to debt securities, not common stock. A rating would address lending risk, not determine the value or performance of Anthropic shares.
When will Anthropic’s IPO take place?
Anthropic has filed to list on Nasdaq under the symbol ANT, but it has not announced the share count, price range or listing date.
Why is Blackstone’s forecast notable despite Anthropic’s growth?
The reported outlook highlights lenders’ focus on repayment risk and financing commitments as well as revenue growth. Anthropic disclosed $16.3 billion in first-half 2026 revenue and positive operating cash flow, alongside substantial compute-related commitments. The rating agencies’ eventual assessments are not known.
