TL;DR
The Financial Times reported that Blackstone expects Anthropic to receive a high-yield, double-B credit rating after its planned IPO, a change from Blackstone’s earlier expectation of investment grade before 2027. That forecast has not been confirmed by Anthropic, Blackstone or a major rating agency; Anthropic’s filing confirms it does not yet meet the investment-grade condition in a credit agreement.
The Financial Times reported on October 30 that Blackstone expects Anthropic to receive a high-yield, double-B credit rating after its planned stock market debut, a forecast that differs from Blackstone’s earlier expectation that the AI company would reach investment grade before 2027. The prediction is not a rating-agency decision: no Moody’s, S&P or Fitch rating has been announced, and both Anthropic and Blackstone declined to comment when asked by TechCrunch.
TechCrunch summarized the Financial Times report, which concerned a $63 billion chip-financing deal for Anthropic. According to TechCrunch, Blackstone told investors it now expects Anthropic to receive a rating in the double-B range, the highest tier below investment grade. TechCrunch characterized the forecast as a prediction, not a confirmed outcome. The Financial Times article is behind a paywall, and the available account does not establish that a rating agency has reached a decision.
Anthropic’s October 26 registration statement provides relevant confirmed information. The company said its $15 billion credit line is secured by substantially all of its assets until it obtains investment-grade ratings from at least two of Moody’s, S&P and Fitch. The filing also reported $6.2 billion in debt as of June 30, consisting of convertible notes held by Amazon. These disclosures show that investment-grade ratings are a condition in a financing agreement; they do not confirm what rating the company will receive.
The financing structure is also documented. A joint announcement said a newly formed special-purpose vehicle will buy Broadcom accelerators and networking equipment and lease them to Anthropic. Blackstone is the sole provider of the committed portion of the deal’s second-lien financing, which ranks behind senior loans. Broadcom’s October 26 filing describes residual-value support of up to about $43 billion. Those arrangements explain why lenders and investors may focus on repayment risk, but they do not establish that Anthropic is in default or unable to pay.
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

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 Affect
A credit rating concerns the perceived risk of lending to a company, not the quality of its shares or its products. If a rating agency places Anthropic below investment grade, lenders may view its borrowing as riskier and seek higher interest or other protections. That could affect the terms and cost of future financing, although the reported Blackstone forecast alone does not show that borrowing costs have changed.
The issue matters because Anthropic’s expansion depends on substantial computing capacity and financing commitments. Its filing reported $16.3 billion in revenue in the first half of 2026 and positive cash from operations over that period. At the same time, the source account estimates that named compute contracts total about $637 billion, with some payments due regardless of actual usage. That figure is the source author’s sum, not a number independently confirmed here; the filing’s commitments and their timing would need to be examined in full to assess the company’s obligations.
For customers and businesses using Claude, a possible speculative-grade rating is not evidence of an imminent service interruption. The more direct questions are whether financing costs, infrastructure investment, prices or contract terms change. A forecast about credit risk cannot by itself answer those questions.

IPO Filing and Rating Threshold
Anthropic filed its registration statement on October 26, 2026, proposing to list on Nasdaq under the symbol “ANT.” The filing is not a completed public offering: the share count, price range and listing date had not been set in the source material. A public listing would not itself determine the company’s credit rating, which is a separate assessment of debt risk.
The distinction between investment grade and speculative grade is generally drawn between BBB-minus and BB. The SEC’s investor bulletin on credit ratings explains that ratings apply to debt securities, not common stock, and reflect an agency’s opinion about credit risk. A double-B rating is below investment grade, but it is not the same as a declaration of default. Ratings can change and are not guarantees that a borrower will or will not repay.
There is also a difference between the company’s operating figures and its contractual exposure. Revenue and positive operating cash flow describe reported performance over a period; long-term financing and compute commitments describe potential future obligations. Neither alone settles the rating question. Agencies would make their own judgments using information and methods that are not fully represented by a single investor’s reported forecast.
“Credit ratings apply to debt securities and do not apply to equity securities like common stock.”

No Agency Rating Has Been Announced
The central uncertainty is whether any major agency will assign Anthropic a double-B rating, an investment-grade rating or something else, and when that assessment might be made. The available information contains no published decision from Moody’s, S&P or Fitch. The reported change in Blackstone’s outlook is attributed to the Financial Times account as summarized by TechCrunch; it has not been confirmed directly by Blackstone or Anthropic, both of which declined to comment.
The underlying Financial Times report is behind a paywall, and the source material does not provide its full evidence or wording. It also mentions earlier coverage of ratings from smaller agencies on parts of Anthropic’s debt but does not supply details. The source account’s estimate of roughly $637 billion in compute contracts is its own calculation, so the components, accounting treatment and payment schedule cannot be verified from the material provided. The eventual IPO terms, the company’s financing costs and any effects on customer contracts also remain unsettled.
Watch for Agency and IPO Filings
The next concrete developments to watch are any public rating actions by Moody’s, S&P or Fitch, further disclosure about Anthropic’s financing arrangements, and updates to its IPO registration statement. The filing process may add details about the proposed offering, financial performance, debt and contractual commitments, but the source material does not give a timetable for pricing or the start of trading.
Until an agency publishes a rating or the companies provide further information, the double-B outlook should be described as Blackstone’s reported expectation, not as Anthropic’s assigned rating or a settled judgment on its ability to meet obligations. Readers should distinguish that forecast from the financial figures and contract terms reported in the filing, and from any future effect on borrowing costs or Claude’s availability.
Key Questions
Has Anthropic been given a junk credit rating?
No rating from Moody’s, S&P or Fitch is identified in the available information. The Financial Times reported that Blackstone expects Anthropic to receive a double-B rating after its IPO; that is a forecast, not an agency decision.
What does a double-B rating mean?
Double-B is generally in the speculative-grade, below-investment-grade category. It indicates an agency’s assessment of debt risk; it is not a finding that the company has defaulted.
Does a junk rating mean Anthropic is running out of money?
No. A credit rating assesses perceived risk in repaying debt. Anthropic’s filing reported $16.3 billion in first-half 2026 revenue and positive operating cash flow, alongside substantial financing and computing commitments. Those figures do not determine the rating on their own.
Would a lower rating affect Claude users?
Not automatically. The report does not establish a service interruption or a change to Claude. Possible effects, if financing terms change, could concern the cost of borrowing, investment plans, prices or customer contracts; no such effect is confirmed in the material available.
