Blackstone, the anchor investor in the $63 billion financing package that will buy Broadcom chips and lease them to Anthropic, has told investors in that deal it expects the ChatGPT rival to receive a "high" junk credit rating once it completes its initial public offering, according to a Financial Times report carried by TechCrunch.
The disclosure marks a striking reversal. The FT notes that Blackstone had previously told investors the opposite — that Anthropic, the maker of the Claude assistant, would win an investment-grade rating, indicating low risk for lenders, before 2027 arrives. The firm now expects a rating in the double-B range, the top tier of what markets colloquially call junk status: still speculative, but the strongest grade within it. TechCrunch reports that both Anthropic and Blackstone declined to comment. For more context on this story, see our ongoing latest AI developments.
A Reversal on Creditworthiness
Credit ratings shape who can lend to a company and at what price. A double-B rating sits one notch below the investment-grade boundary, and a "high" junk designation would narrow the pool of institutional buyers for Anthropic's debt, since many bond funds are barred from holding speculative-grade paper. It would also raise the yield Anthropic would need to offer investors to compensate for the perceived risk.
For a company whose business model depends on locking in enormous volumes of compute, the difference between investment-grade and junk-tier borrowing costs is not cosmetic. The FT's reporting suggests Blackstone's revised view reflects the reality on the ground after Anthropic's regulatory filing made its financials public.
The Filing That Changed the Conversation
Anthropic officially filed to go public earlier this week, becoming the first frontier AI lab to seek a public listing, as Bloomberg reported. According to the Associated Press, the filing with the Securities and Exchange Commission runs to 335 pages, of which 93 are devoted to risk factors — a proportion the AP noted dwarfs rival SpaceX's 38 risk pages out of more than 250.
The risk factors range from the mundane to the existential: difficulty retaining key staff, regulatory roadblocks, involvement in cyberattacks, the spread of dangerous misinformation, and the possibility that Anthropic's own models advance so quickly that adequate safety measures cannot keep pace. In a letter to prospective shareholders, the company's founders wrote that "to build AI is to harness cognition itself, and anything so powerful can be used for ill as well as good."
CNBC's analysis of the filing highlighted the tension at its core: roughly 900% revenue retention on the one hand, and approximately $80 billion in first-half losses on the other. Those numbers explain why credit assessors have been unconvinced by the investment-grade case, even as equity investors prepare for what could be one of the largest listings in history.
What Junk Status Would Mean for the Compute Arms Race
Anthropic has spent the past twelve months assembling a series of record-setting compute deals — including the $63 billion Broadcom chip-financing structure announced on October 26 by Bank of America, Blackstone, Citi and Morgan Stanley, in which a special purpose vehicle purchases the hardware and leases it to the AI lab. Analysts have flagged that such structures shift enormous obligations onto future revenue streams.
A junk-tier rating would make similar deals more expensive to arrange, because lenders would demand higher returns to hold the paper. It could also complicate Anthropic's ability to raise fresh capital at favorable terms if the broader market's appetite for AI-related debt keeps cooling. Investors have grown visibly nervous about AI cash burn in recent weeks, with Wall Street's October selloff deepening the scrutiny on every new financing announcement.
It is worth stressing what Blackstone's expectation is not: it is not a rating. Agencies such as S&P, Moody's and Fitch have not published post-IPO ratings for Anthropic, and the actual assessments could differ. But anchor investors' internal forecasts tend to leak into pricing conversations, and the FT report suggests the era of assuming Anthropic borrows at blue-chip rates is over.
A Listing That Will Test the AI Trade
Anthropic's IPO has been framed by the company itself as a step toward safer AI — the filing argues that going public imposes public accountability on a company building frontier systems. Investors will likely focus on something more prosaic: whether a lab spending tens of billions of dollars a year on compute can generate returns fast enough to justify its valuation once public-market discipline applies.
The credit-rating question sits at the center of that calculation. If Anthropic lists and is quickly assessed in the double-B range, every subsequent data-center lease and chip-financing vehicle it signs will carry a visible risk premium — a real-world price tag on the gap between the AI industry's ambitions and its current cash flows. For the broader market of neoclouds, SPVs and GPU-backed debt, Anthropic's rating will function as a benchmark for the entire sector.
The company has not set a listing date, and valuation expectations have already been tempered in recent weeks as revenue growth showed signs of slowing. What happens when the rating agencies publish their first post-IPO assessments may matter as much as the IPO price itself.
