TL;DR
The Financial Times reported that Blackstone expects Anthropic to receive a high-yield, double-B credit rating after its planned IPO, reversing an earlier expectation of investment grade before 2027. Anthropic has filed to go public, but no rating agency has announced a rating and key IPO terms are not set.
Blackstone reportedly expects Anthropic to receive a high-yield credit rating after its planned stock-market debut, 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 publicly issued a rating, and Anthropic’s IPO terms are not yet set.
According to TechCrunch’s account of the Financial Times report, Blackstone told investors in a $63 billion chip-financing deal that it now expects Anthropic to receive a rating in the double-B range after an IPO. Double-B is the highest tier below investment grade. The report said Blackstone had previously expected investment grade before 2027. Blackstone and Anthropic declined to comment to TechCrunch, which described the forecast as a prediction.
The company’s October 26 registration statement confirms that Anthropic has filed to list on Nasdaq under the proposed ticker ANT. It does not yet provide a share count, price range or listing date. The filing also says a $15 billion credit line is secured by substantially all of Anthropic’s assets until it receives investment-grade ratings from at least two of Moody’s, S&P and Fitch. That provision describes a financing condition; it is not itself a rating decision.
Anthropic reported $6.2 billion in debt as of June 30, all in convertible notes held by Amazon, according to the filing. Separately, a joint announcement describes the $63 billion financing vehicle, which 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, the more junior part of the arrangement. Broadcom’s October 26 filing says it provides 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.

- $63B chip deal: Blackstone is the sole committed second-lien lender; Broadcom backs up to about $43B

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 a Credit Rating Could Matter
A speculative-grade rating would concern the terms and perceived risk of borrowing, not the value or prospects of Anthropic shares. The SEC explains that credit ratings apply to debt securities, not common stock, and represent an agency’s assessment rather than a guarantee of repayment. A lower rating can mean lenders view repayment as riskier and demand a higher return, though the exact effect depends on the financing and market conditions.
For Anthropic, the issue is the scale and structure of its commitments alongside the pace of its growth. The source material says the company recorded $16.3 billion in revenue in the first half of 2026 and turned cash flow from operations positive. It also calculates about $637 billion in compute contracts named in the filing, many with payments due regardless of actual usage. That total is the source author’s sum, not a figure independently identified here as a company-reported aggregate. The contrast helps explain why lenders might weigh future obligations and revenue uncertainty differently from headline growth.
For customers and businesses using Claude, a rating forecast does not indicate an imminent service interruption. Its practical relevance is indirect: borrowing costs and access to capital can affect a company’s ability to fund infrastructure and expansion. Customers assessing dependence on an AI provider may track pricing, contract terms and the ease of switching, rather than treating an unissued rating as evidence of a service change.

IPO Filing and Financing Commitments
Anthropic’s registration statement was filed on October 26, 2026, but filing is not the same as completing an IPO. The company has not set its offering price, the number of shares to sell or the date of a listing. The proposed Nasdaq ticker is ANT. The filing’s credit-line provision ties its release of collateral to investment-grade ratings from two of the three named agencies, showing that rating status has a specific contractual relevance.
The reported Blackstone forecast relates to the company’s financing needs, not an assessment of its stock. In the financing arrangement described in the October 26 joint release, a special-purpose vehicle is to buy Broadcom equipment and lease it to Anthropic. Blackstone’s role concerns the committed second-lien portion, while Broadcom provides stated residual-value support. These are distinct parts of the financing; the reported forecast does not establish that the deal has failed or that Anthropic cannot meet its obligations.
For a plain-language benchmark, the SEC says the dividing line between investment grade and speculative grade is generally between BBB and BB. BBB-minus or higher is investment grade; ratings below that line are non-investment grade, also called speculative or high yield. “Junk” is a blunt market term for the latter category. A double-B rating would be below investment grade, but it would not, by itself, mean default or insolvency.
“Credit ratings apply to debt securities” and “do not apply to equity securities like common stock.””

Rating Decision Still Unissued
The central uncertainty is whether Moody’s, S&P or Fitch will rate Anthropic, what rating any agency might assign and when. The supplied reporting contains Blackstone’s reported expectation, not a published agency decision. The Financial Times article is behind a paywall, and TechCrunch’s summary is the available account described in the source material; Anthropic and Blackstone declined to comment to TechCrunch.
The IPO’s price range, share count and timing also remain unset. Nor does the reported forecast establish how any rating would affect the cost or availability of particular financing. The source material mentions earlier reports involving smaller rating agencies and parts of Anthropic’s debt but does not provide details that can be independently assessed here. A rating can change, and it is not a promise that a borrower will repay or default.
IPO Terms and Agency Ratings
The next observable milestones are Anthropic’s further IPO disclosures, including any eventual price range, share count and timetable, and any public rating action by Moody’s, S&P or Fitch. Until an agency issues a rating, Blackstone’s reported view should be treated as an investor forecast rather than a formal credit assessment.
Investors and customers can also watch for company disclosures about financing, operating performance and infrastructure commitments. Those details may clarify how Anthropic plans to fund its growth, but they will not by themselves determine a credit rating. For now, the confirmed facts are that Anthropic has filed to go public and has financing arrangements tied to an investment-grade threshold; the eventual rating and the IPO’s final terms remain unknown.
Key Questions
Has Anthropic received a junk rating?
No rating from Moody’s, S&P or Fitch is identified in the supplied material. 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 a speculative-grade category below investment grade. It signals a higher assessed risk to lenders than an investment-grade rating; it does not, by itself, mean a company is in default.
No. Credit ratings concern debt, not common stock. The report concerns an expected borrower rating, not a rating or forecast for the value of Anthropic’s shares.
When will Anthropic go public?
Anthropic has filed a registration statement and proposed the Nasdaq ticker ANT, but the filing described in the source material does not set a listing date, offer price or number of shares.
