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. That forecast has not been confirmed by Blackstone or Anthropic, and no rating from Moody’s, S&P or Fitch has been published. Anthropic’s October 26 filing confirms it does not yet meet an investment-grade condition in a credit agreement.
Blackstone reportedly expects Anthropic to receive a double-B credit rating after its planned stock-market debut, according to a Financial Times report published October 30 and summarized by TechCrunch. The forecast would put the Claude maker below investment grade, but it is one lender’s reported expectation, not a rating agency decision; Anthropic and Blackstone declined to comment, and no rating from Moody’s, S&P or Fitch has been published.
TechCrunch’s account of the Financial Times report says Blackstone told investors in a $63 billion chip-financing deal that it now expects Anthropic to receive a “high” speculative-grade rating in the double-B range after an IPO. The report says Blackstone had previously expected the company to reach investment grade before 2027. The Financial Times article is behind a paywall, and the source material does not include its full text, so the forecast is attributable to the outlets’ reporting rather than a public statement from Blackstone.
Anthropic’s October 26 registration statement provides a separate, confirmed data point: a credit agreement for a $15 billion line of credit ties a change in its terms to the company obtaining investment-grade ratings from at least two of Moody’s, S&P and Fitch. That condition indicates Anthropic had not met the specified rating threshold when it filed. The filing reports $6.2 billion in debt as of June 30, all in convertible notes held by Amazon.
The financing documents describe a deal structured through a special-purpose vehicle that will buy Broadcom accelerators and networking equipment and lease them to Anthropic. A joint announcement identifies Blackstone as the sole provider of the committed portion of the deal’s second-lien financing. Broadcom’s filing says it is providing residual-value support of up to about $43 billion. These documents confirm the financing structure; they do not confirm 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)

- $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

How a Rating Could Affect Anthropic
A credit rating assesses the risk of a borrower repaying debt; it is not a grade for Anthropic’s shares and does not by itself mean the company is near default. Under the categories described by the U.S. Securities and Exchange Commission, BBB-minus is the lowest investment-grade rating, while BB ratings fall below that line. A double-B rating is commonly described as speculative grade or “junk.”
If agencies assign a below-investment-grade rating, lenders may view Anthropic as a riskier borrower and demand higher returns or tighter terms. That could matter to the cost and availability of the financing required for chips and data centers. It would not automatically establish that Anthropic cannot pay its bills. For customers and businesses using Claude, the practical issue is whether financing costs or capacity decisions later affect prices, service plans or availability. No such customer impact is established by the report.

IPO Filing and Credit Commitments
Anthropic filed a registration statement on October 26, 2026, proposing a Nasdaq listing under the symbol “ANT.” At the time described in the source material, the company had not set the number of shares, price range or listing date. The IPO filing is therefore a proposed offering, not a completed public listing.
The filing also describes substantial spending commitments for computing capacity. The source article calculates that named compute contracts total about $637 billion, while noting that many payments are due regardless of actual usage. That figure is the author’s sum of contracts disclosed in the filing, not a single company-reported total. The same account says Anthropic recorded $16.3 billion in revenue in the first half of 2026 and positive operating cash flow. Those operating figures provide context, but they do not settle how rating agencies will judge future debt repayment risk.
Rating assessments are forward-looking opinions that can change. The SEC says credit ratings apply to debt securities, not common stock, and are based on an agency’s view of credit risk. The reported double-B expectation should therefore be kept distinct from both Anthropic’s operating results and the eventual market price of any shares.
“Credit ratings apply to debt securities and do not apply to equity securities like common stock.”
— U.S. Securities and Exchange Commission investor bulletin, “The ABCs of Credit Ratings”
No Agency Rating Published Yet
The central uncertainty is whether any major rating agency will assign Anthropic a double-B rating, or what rating it may receive after the IPO. The source material says no public decision from Moody’s, S&P or Fitch was available and no agency statement confirmed Blackstone’s reported expectation. Blackstone and Anthropic declined to comment to TechCrunch.
The IPO’s share count, price range and timing were also not set in the filing information provided. The details of how agencies might weigh Anthropic’s revenue growth, debt, cash and long-term compute commitments remain unknown. A reported lender forecast cannot establish how other lenders, investors or rating agencies will assess those factors.
Agency Decisions and IPO Terms
The next clear milestones are the publication of any ratings by Moody’s, S&P or Fitch and further filings that set out Anthropic’s IPO terms. Until then, Blackstone’s reported view remains a forecast rather than an official credit rating. Investors and customers can distinguish confirmed developments from that forecast by watching for agency announcements, updated registration documents and any public response from Anthropic or Blackstone.
Anthropic’s filing also makes its financing conditions and compute commitments relevant points to follow as the offering progresses. Whether those obligations change, how they are funded and whether a rating affects borrowing terms have not been established in the available material.
Key Questions
Has Anthropic received a junk credit rating?
No public rating from Moody’s, S&P or Fitch is identified in the source material. The double-B expectation is attributed to Blackstone through Financial Times reporting summarized by TechCrunch.
What does a double-B rating mean?
Double-B is below the investment-grade threshold and is generally categorized as speculative grade or high yield. It indicates a higher assessed credit risk; it does not by itself mean default is imminent.
No. Credit ratings assess debt risk, not the value or quality of common stock. Any rating discussed in the report would concern Anthropic as a borrower.
Has Anthropic completed its IPO?
No. Anthropic filed a registration statement on October 26, 2026, proposing a Nasdaq listing under “ANT.” The supplied information says the share count, price range and listing date were not yet set.
Why might a fast-growing company still be considered a risky borrower?
Rating agencies assess the ability to repay debt, including future obligations and financing needs, rather than growth alone. Anthropic reported strong revenue and positive operating cash flow in the first half of 2026, while its filing also describes large compute commitments. How agencies will weigh those factors is not yet known.
