TL;DR
The Financial Times reported that Blackstone expects Anthropic to receive a double-B, speculative-grade rating after its planned IPO. That is an investor forecast, not a published rating: Anthropic has filed to go public, but Moody’s, S&P and Fitch have not announced a decision. Its filings show substantial debt and large compute commitments alongside rapid revenue growth.
Blackstone reportedly expects Anthropic to receive a double-B, speculative-grade credit rating after the Claude maker goes public, according to a Financial Times report summarized by TechCrunch. The forecast is not a rating-agency decision: Anthropic has filed for an IPO, but no published rating from Moody’s, S&P or Fitch has been identified.
The Financial Times reported on October 30 that Blackstone, a major lender to Anthropic, now expects the company to receive a “high” junk rating in the double-B range after its stock market debut. TechCrunch summarized the report, saying Blackstone had previously expected Anthropic to reach investment grade before 2027. Blackstone and Anthropic declined to comment to TechCrunch, according to its account. The Financial Times article is behind a paywall, and the details here rely on the available summary.
Anthropic’s October 26 registration statement confirms it does not yet meet a credit agreement condition tied to receiving 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, consisting of convertible notes held by Amazon.
Other figures in the filing point to both rapid expansion and substantial financial obligations. Anthropic reported $16.3 billion in revenue for the first half of 2026 and positive cash from operations. The source’s own tally of compute contracts is about $637 billion; it says many obligations are payable regardless of actual usage. That total is an author calculation, not a figure presented as such by a rating agency.
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

- 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 Lenders May See More Risk
A speculative-grade rating could affect the cost and availability of borrowing, because lenders generally demand higher returns when they judge repayment risk to be greater. But the reported forecast does not establish that Anthropic will receive such a rating, nor does it mean the company is close to default. It is an expectation attributed to one investor, not a public conclusion by a ratings agency.
The tension is relevant to customers and business partners because Anthropic is expanding while taking on long-term infrastructure commitments. Large compute bills may remain due even if usage or revenue changes. At the same time, the company’s reported revenue growth and positive operating cash flow are part of the financial picture. A credit rating would address the risk attached to debt, not the quality of Claude or the value of Anthropic’s shares.
For companies relying on Anthropic’s services, a possible rating change is not evidence of an impending service interruption. Practical questions include pricing, contract terms and the ability to move workloads if business conditions change. The information available does not establish that customers need to alter their plans now.

The IPO and Financing Structure
Anthropic filed a registration statement on October 26 and plans to list on Nasdaq under the symbol ANT. The filing does not set the number of shares, offering price range or listing date. The IPO is therefore in process, not a completed market debut.
A joint announcement on October 26 described a $63 billion chip-financing arrangement involving a newly formed special-purpose vehicle. The vehicle is to buy Broadcom accelerators and networking equipment and lease them to Anthropic. The announcement identifies Blackstone as the sole provider of the committed portion of the second-lien financing, which ranks behind senior loans in repayment priority. Broadcom’s October 26 filing says it will provide residual-value support of up to about $43 billion.
“Junk” is a market term for debt below investment grade, also called speculative grade or high yield. The SEC says the dividing line commonly falls between BBB and BB categories; BBB-minus or higher is generally investment grade. A double-B rating would sit below that threshold. Ratings are assessments of debt repayment risk and can change; they are not ratings of common stock.
“Credit ratings apply to debt securities.”
— U.S. Securities and Exchange Commission investor bulletin, “The ABCs of Credit Ratings”
No Agency Rating Has Been Published
The central point remains unconfirmed: no rating agency decision is established by the material available. The reported double-B outlook comes from Blackstone, as described by the Financial Times and summarized by TechCrunch. Neither company commented to TechCrunch, and no public statement from Moody’s, S&P or Fitch is cited.
The eventual rating, its timing and the agencies’ reasoning are unknown. The IPO’s share price, size and date are also unsettled. Anthropic’s filing documents financial obligations and conditions, but it does not confirm how an agency will weigh those obligations against revenue, cash flow, assets or other factors. The $637 billion compute-contract figure is the source author’s sum, and the provided material does not give an agency assessment of that calculation.
IPO Terms and Ratings Decisions
The next visible milestones are publication of Anthropic’s final IPO terms and its eventual listing, if the offering proceeds. The company has not set a price range, share count or date in the filing described here. Credit-rating agencies could issue assessments before or after the listing, but no timetable is confirmed in the source material.
Investors and customers can distinguish new disclosures from forecasts by checking for statements from the company, the financing participants and the rating agencies themselves. Until such a decision appears, Blackstone’s reported expectation should not be treated as an assigned rating. Any change to the credit-line condition, financing costs or customer terms would need to be confirmed separately.
Key Questions
Has Anthropic received a junk credit rating?
No published rating from Moody’s, S&P or Fitch is identified in the available reporting. The double-B expectation is attributed to Blackstone in a Financial Times report summarized by TechCrunch.
What does a double-B rating mean?
Double-B is below the commonly used investment-grade cutoff of BBB-minus. It is a speculative-grade assessment of debt risk, not a declaration that a borrower has defaulted.
Does a possible junk rating apply to Claude or Anthropic’s stock?
No. A credit rating concerns debt repayment risk, not the quality of Claude or the value of common shares. The SEC distinguishes ratings on debt from ratings on equity.
Why might lenders be concerned despite Anthropic’s growth?
The company reported $16.3 billion in first-half 2026 revenue and positive cash from operations, but its filing also records $6.2 billion in debt and large compute commitments. How a rating agency would balance those factors is not known.
When will Anthropic go public?
Anthropic has filed to list on Nasdaq under the symbol ANT, but the material provided does not set an offering price range, share count or listing date.
