TL;DR
Blackstone reportedly told investors it expects Anthropic to receive a double-B, below-investment-grade rating after its IPO, reversing an earlier expectation that the company would reach investment grade before 2027. The forecast is not a published credit rating: Anthropic’s IPO filing is preliminary, and the major rating agencies have not announced a decision.
Blackstone reportedly expects Anthropic to receive a double-B, below-investment-grade credit rating after the AI company’s planned stock market debut, according to a Financial Times report summarized by TechCrunch. The forecast matters because it differs from Blackstone’s earlier expectation that Anthropic would reach investment grade before 2027, but no rating agency has publicly issued a rating and the company’s IPO terms are not yet set.
The Financial Times reported on October 30 that Blackstone, described by TechCrunch as an anchor investor in a $63 billion chip-financing deal, told investors it now expects Anthropic to receive a “high” junk rating in the double-B range after its IPO. TechCrunch reported that Blackstone had previously expected Anthropic to obtain an investment-grade rating before 2027. The report is a forecast attributed to one investor, not a decision by Moody’s, S&P or Fitch. Anthropic and Blackstone declined to comment to TechCrunch.
Anthropic’s October 26 registration statement confirms that its credit agreement links the release of substantially all of its assets from security to receiving investment-grade ratings from at least two of Moody’s, S&P and Fitch. The filing also reports $6.2 billion in debt as of June 30, consisting of convertible notes held by Amazon. Separately, the joint announcement for the chip deal says Blackstone is the sole provider of the committed portion of its second-lien financing, which ranks behind senior loans. Broadcom’s filing says it provides residual-value support of up to about $43 billion for the arrangement.
The IPO filing is preliminary: Anthropic plans to list on Nasdaq under the symbol ANT, but has not set a share price, price range, share count or listing date. The filing reports $16.3 billion in revenue for the first half of 2026 and positive cash from operations during that period. It also lists large compute commitments; the source’s author calculates their total at about $637 billion and says many payments are due regardless of actual usage. That figure is a calculation from the listed contracts, not a rating-agency assessment.
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

How a Lower Rating Could Raise Borrowing Costs
A credit rating addresses the risk that a company will repay its debt, not whether its shares are a good investment. Under the SEC’s explanation of credit ratings, BBB-minus and above is generally investment grade, while BB ratings fall below that boundary. A double-B rating is the top tier of speculative-grade debt, but it is not a declaration of default or proof that a company cannot meet its obligations.
If agencies ultimately assign Anthropic a below-investment-grade rating, lenders may view its borrowing as riskier and seek higher interest or other protections. That could affect the cost and terms of financing for a company making substantial commitments to computing capacity. The rating would also matter to investors evaluating the debt structure around the IPO. However, Blackstone’s reported forecast alone does not establish what Anthropic will pay to borrow or how its shares will trade.
For customers and business partners, the practical questions are more indirect: whether financing conditions influence Anthropic’s ability to fund computing infrastructure, and whether that has consequences for service terms or prices. The supplied reporting does not establish that a rating forecast will cause a service interruption, price change or reduction in product availability. Any such outcome remains speculative.

IPO Filing and Chip Financing
Anthropic filed its registration statement on October 26, 2026, beginning the public-offering process but not setting the final terms. A filing gives prospective investors information to assess; it does not by itself mean shares are already trading or that the offering price is known.
The reported rating forecast comes amid financing arrangements tied to Anthropic’s computing needs. The announced $63 billion transaction uses a newly formed special-purpose vehicle to buy Broadcom accelerators and networking equipment and lease them to Anthropic. Blackstone’s role is in the committed second-lien portion of the financing, while Broadcom has disclosed residual-value support of up to about $43 billion. Those details are disclosed in company announcements and filings; the revised rating expectation comes from the Financial Times report as summarized by TechCrunch.
The scale of Anthropic’s reported business and cash resources does not settle how agencies will evaluate its credit. A rating considers repayment risk and the terms and demands attached to debt, among other factors. Rapid revenue growth and positive operating cash flow can coexist with questions about future spending and fixed contractual commitments. The available source material does not include a rating-agency analysis of Anthropic’s finances.
“Credit ratings apply to debt securities.”

No Agency Rating or IPO Price Yet
No public rating from Moody’s, S&P or Fitch is identified in the source material, and the agencies’ views and timing are unknown. Blackstone and Anthropic declined to comment to TechCrunch, which summarized the Financial Times report; the original article is behind a paywall, so its full evidence and wording cannot be independently assessed from the supplied material.
It is also unclear whether Blackstone’s reported expectation will prove accurate, whether other lenders share it, or what ratings agencies will assign after reviewing Anthropic’s finances and obligations. The source material does not establish the final IPO price, share count, timing, or the interest rates and other terms Anthropic may face under future borrowing. The reported compute-contract total is the source author’s calculation, not an agency figure.
Rating Decisions and IPO Terms
The next concrete developments are the publication of Anthropic’s final IPO terms and any public rating actions by Moody’s, S&P or Fitch. Investors will be able to assess the offering’s price range, share count and other details when they are filed. Until an agency issues a rating, Blackstone’s reported view remains an expectation, not an official assessment.
For readers tracking the financing, relevant disclosures include changes to Anthropic’s registration statement, updates to the chip-financing arrangement, and any stated credit-rating conditions in new agreements. No date for the IPO or for agency decisions has been announced in the supplied material.
Key Questions
Has Anthropic been given a junk credit rating?
No rating from Moody’s, S&P or Fitch is identified in the source material. The double-B expectation is Blackstone’s reported forecast, not a published agency rating.
What does a double-B rating mean?
Double-B is below the commonly used investment-grade boundary of BBB-minus. It is considered speculative grade and signals a lender’s assessment of higher repayment risk; it does not mean the borrower is in default.
Would a junk rating grade Anthropic’s stock?
No. Credit ratings assess debt securities and repayment risk, not common stock. A rating would be about lending to Anthropic, not a rating of its IPO shares.
When will Anthropic’s IPO price be known?
The company’s registration statement names Nasdaq and the proposed ticker ANT, but the supplied material gives no price range, share count or listing date. Those details remain unannounced.
