TL;DR
The Financial Times reported that Blackstone now expects Anthropic to receive a double-B, speculative-grade credit rating after its planned IPO, rather than investment grade before 2027. That is an investor forecast, not a rating-agency decision; Anthropic has filed for an IPO but has not set its share price or date.
Blackstone reportedly expects Anthropic to receive a double-B, speculative-grade credit rating after its planned stock-market debut, according to a Financial Times report published October 30. The forecast is not a rating-agency decision: no public rating from Moody’s, S&P or Fitch was identified, and Anthropic’s IPO has been filed but not priced.
TechCrunch summarized the Financial Times report, saying Blackstone shared its revised expectation with investors in connection with a $63 billion chip-financing deal. Blackstone reportedly expects a rating in the double-B range, which sits below investment grade. The earlier expectation, also attributed to Blackstone, was that Anthropic would reach investment grade before 2027. Both Anthropic and Blackstone declined to comment when asked by TechCrunch, which described Blackstone’s forecast as a prediction.
Anthropic’s October 26 registration statement confirms that it has not yet met a credit agreement condition tied to obtaining investment-grade ratings from at least two of Moody’s, S&P and Fitch. The filing says a $15 billion credit line is secured by substantially all of the company’s assets until that condition is met. The filing also reports $6.2 billion in debt as of June 30, all in convertible notes held by Amazon.
The financing structure is separately documented in an October 26 joint announcement: a newly formed special-purpose vehicle will buy Broadcom accelerators and networking equipment and lease them to Anthropic. Blackstone is identified as the sole provider of the committed portion of the second-lien financing, which ranks behind senior loans. Broadcom’s October 26 filing says it is providing residual-value support of up to about $43 billion. These documents establish the financing arrangements, not Blackstone’s reported rating forecast.
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

What a Lower Rating Could Change
A rating below investment grade can affect the cost and availability of borrowing. Lenders generally view speculative-grade debt as riskier and may seek higher interest or stronger protections. For Anthropic, a lower rating than Blackstone reportedly expected could matter as the company finances computing infrastructure and meets obligations connected to long-term equipment and capacity agreements.
It would not mean that Anthropic is bankrupt or unable to pay its bills. Nor would it rate the company’s shares: credit ratings concern debt, not common stock. The practical significance is how lenders assess repayment risk and what terms they demand, not an automatic judgment about Claude’s quality or an immediate change to the service.
The reported forecast also draws attention to a tension in the company’s financial picture. Anthropic’s filing reports $16.3 billion in revenue for the first half of 2026 and positive cash from operations. At the same time, the source’s review of the filing calculates roughly $637 billion in named compute contracts, many payable regardless of actual usage. That total is the source’s calculation, not a rating-agency finding, and the contracts’ scale alone does not establish that the company will default.

IPO Filing and Credit Threshold
Anthropic, which makes the Claude AI products, filed its registration statement on October 26, 2026, and plans to list on Nasdaq under the symbol “ANT.” The filing does not set the number of shares, an offering price range or a listing date. The prospectus describes the terms of the company’s credit arrangements, including the requirement for investment-grade ratings from at least two of the three major agencies before the secured credit line’s collateral arrangement changes.
The distinction between investment grade and speculative grade is commonly drawn between the BBB and BB categories. The SEC’s investor bulletin on credit ratings explains that BBB-minus or higher is generally investment grade, while lower ratings are commonly called non-investment grade, speculative or high yield. Double-B, if that is the rating ultimately assigned, would be just below the investment-grade boundary. A rating is an agency’s assessment of credit risk, not a guarantee of repayment or a prediction of a specific outcome.
“Credit ratings apply to debt securities.”
— U.S. Securities and Exchange Commission investor bulletin
No Agency Rating Is Public
No public decision from Moody’s, S&P or Fitch was identified, so the eventual rating, its timing and the reasoning behind it remain unknown. The Financial Times report is behind a paywall, and the account available here comes through TechCrunch’s summary. Blackstone and Anthropic did not comment to TechCrunch, leaving the lender’s reported forecast without direct public confirmation from either company.
The IPO itself remains incomplete: the share count, price range and listing date have not been set in the available information. It is also not clear whether the reported forecast applies to a particular borrowing or to Anthropic’s credit profile more broadly. A future rating could differ from Blackstone’s expectation, and agencies may revise ratings as company finances and financing terms change.
IPO Terms and Agency Decisions
The next public milestones are likely to come through updates to Anthropic’s IPO registration statement, including any share count, price range and expected timetable. Investors and lenders will also be watching for formal rating actions from Moody’s, S&P and Fitch, rather than treating the reported Blackstone view as an agency decision.
Until those details emerge, the reported forecast should be read narrowly: it signals what one lender reportedly expects, not a settled verdict on Anthropic’s ability to repay debt. The company’s filings and later disclosures may clarify its financing commitments, cash generation and the conditions attached to its credit facilities.
Key Questions
Has Anthropic received a junk credit rating?
No public rating from Moody’s, S&P or Fitch was identified. The double-B expectation was attributed to Blackstone in a Financial Times report summarized by TechCrunch.
What does a double-B rating mean?
Double-B is generally a speculative-grade, or non-investment-grade, category, below the usual investment-grade threshold of BBB-minus. It indicates greater assessed credit risk; it does not by itself mean default.
Does a junk rating grade Anthropic’s stock or Claude?
No. Credit ratings assess debt repayment risk, not common stock or the quality of an AI product. The rating would not, on its own, mean Claude would stop operating.
Has Anthropic set its IPO price or date?
No. Anthropic filed its registration statement on October 26, 2026, but the available information says its share count, price range and listing date have not been set.
