Blackstone tells Anthropic chip-deal investors to expect a double-B junk rating after IPO, FT reports
Blackstone holds the riskier second-lien slice of a $63 billion Broadcom chip financing for Anthropic. It has told investors it now expects Anthropic to get a double-B rating after its IPO. That reverses its earlier guidance that investment grade was within reach.

Reach blends public engagement (views, likes, comments, shares, stars) from the platforms where the story or its original source lives: YouTube, Hacker News, GitHub, Substack and similar. A video and the article written from its transcript share one score, taken from the video. Platforms with no data are left out rather than counted as zero, and the age of a story never lowers its score.
Earlier in 2026, Blackstone told investors that Anthropic could reach investment grade. It now tells investors in the chip financing to expect a 'high' junk rating of double-B once Anthropic goes public. Anthropic and Blackstone both declined to comment. [1] [2] [3]
In the $63 billion deal, a special-purpose vehicle buys Broadcom accelerators and networking gear and leases them to Anthropic. Deliveries are expected to start in 2027. Bank of America, Citi and Morgan Stanley arrange about $43.5 billion of first-lien debt, and Blackstone alone takes the second lien. Broadcom guarantees the senior lenders against the equipment losing value. One inference from this structure: Anthropic's own rating mainly affects what the junior, unguaranteed debt costs. [5] [6]
Anthropic's S-1 shows heavy leverage alongside fast growth. First-half 2026 revenue was $16.3 billion against an $80.7 billion net loss. CNBC attributes about $72 billion of that loss to valuation adjustments on convertible notes. The filing also lists $417 billion in signed data-center and cloud commitments. [4] [7] [8]
Anthropic's compute buildout relies on large lease-backed debt and $417 billion in commitments.

Implication: a sub-investment-grade rating would shrink the pool of buyers, raise borrowing costs and move more credit risk onto suppliers such as Broadcom.
Executive brief
Blackstone anchors the second-lien tranche of a $63 billion Broadcom chip financing for Anthropic. According to the Financial Times, it has told investors in that deal it now expects Anthropic to get a "high" junk rating (double-B) after its IPO. That reverses Blackstone's earlier guidance that an investment-grade rating was likely before 2027 (TechCrunch; FT). The forecast is Blackstone's own. The reviewed sources show no statement from a rating agency. It matters because Anthropic's compute buildout depends heavily on borrowing, and a junk rating would make that debt harder to place and more expensive.
What changed and event timeline
Earlier in 2026: Blackstone signals investment grade
Blackstone had told investors Anthropic could reach an investment-grade rating by year-end. The reporting does not date this earlier guidance (;).
Anthropic files public S-1
Anthropic, PBC filed to list Class A shares on the Nasdaq Global Select Market under "ANT", with Goldman Sachs and Morgan Stanley leading. Share count and price range were not set ().
$63B chip financing disclosed
Bank of America, Citi, Morgan Stanley and Blackstone will fund an SPV that buys Broadcom accelerators and leases them to Anthropic. Reuters dates the report Oct 26; The Tech Capital gives Oct 29 (;).
Blackstone revises its guidance
The FT reports Blackstone now expects a double-B rating after the IPO. Anthropic and Blackstone both declined to comment to TechCrunch (;).
Capabilities and access
This is a financing story, not a model release, and no new Claude version is involved. The $63B deal pays for Broadcom XPU accelerators and networking gear. Deliveries are expected to start in 2027 under an earlier Broadcom compute agreement (Investing.com/Reuters). Shares will not be available to the public until the registration statement becomes effective (Anthropic).
Technical analysis for researchers and developers
How the deal is structured matters more than any model detail here: In practice, Anthropic's own credit rating mostly affects how much the junior, unguaranteed tranches cost.

How the deal is structured matters more than any model detail here:
- Asset-backed leasing. The SPV owns the hardware and Anthropic rents it, so lenders' recovery depends partly on what the chips are worth later.
- Tranches. About $43.5B (69%) is first-lien debt arranged by BofA, Citi and Morgan Stanley. Blackstone alone commits to the riskier second lien (Investing.com/Reuters).
- Vendor backstop. Broadcom gives the senior lenders "residual value support", a guarantee against the equipment losing value. The Tech Capital puts Broadcom's possible exposure at $43B (The Tech Capital).

Claims and evidence
- Double-B expectation: this is Blackstone's forecast, reported by the FT and passed on by TechCrunch.
- S-1 figures: first-half 2026 revenue was $16.3B against an $80.7B net loss.
- Commitments: CNBC reports $417B in signed data-center and cloud commitments.

- Double-B expectation: this is Blackstone's forecast, reported by the FT and passed on by TechCrunch. No agency rating or agency statement appears in the reviewed sources (FT).
- S-1 figures: first-half 2026 revenue was $16.3B against an $80.7B net loss. CNBC attributes about $72B of that loss to valuation adjustments on convertible notes, an accounting charge rather than operating spend (CNBC; Yahoo Finance).
- Commitments: CNBC reports $417B in signed data-center and cloud commitments. Secondary outlets cite more than $800B in long-term compute plans, a figure not confirmed in the primary filings reviewed here (CNBC; AI Weekly).
Context and prior work
- Anthropic previously financed $35B of compute expansion through Apollo and Blackstone, with a Broadcom backstop of up to $29B (Investing.com/Reuters).
- Its last private round was $65B at a $965B valuation in May 2026.
- Other S-1 commitments include up to $120.5B with SpaceX through 2029, $110B with Amazon through 2036 and $44.9B with Microsoft through 2033 (CNBC).

Limitations, safety and contested findings
- Reports disagree on when the $63B deal was announced: Oct 26 per Reuters, Oct 29 per The Tech Capital (Investing.com/Reuters; The Tech Capital).
- Moody's called Broadcom one of the strongest large tech companies, but warned that risk would rise if it backed several frontier-lab deals in a short period (Investing.com/Reuters).
- S-1 risk factors include Pentagon and administration disputes, state moratoriums on data centers, dependence on TSMC, and the possibility that insurance cannot cover catastrophic AI incidents (CNBC; Yahoo Finance).

Business and practitioner implications
- Cost of capital. Anthropic would pay higher yields as a result (AI Weekly).
- Chipmakers such as Broadcom are taking credit risk onto their own balance sheets to support frontier labs. Investors in suppliers should track those guarantees.
- The S-1 shows strong revenue momentum and a first operating profit in Q2 2026 (Yahoo Finance).

- Cost of capital. A double-B rating would shrink the pool of buyers, since many insurers and pension funds cap how much sub-investment-grade debt they hold. Anthropic would pay higher yields as a result (AI Weekly).
- Vendor concentration. Chipmakers such as Broadcom are taking credit risk onto their own balance sheets to support frontier labs. Investors in suppliers should track those guarantees.
- Enterprise buyers. The S-1 shows strong revenue momentum and a first operating profit in Q2 2026 (Yahoo Finance). Even so, the size of Anthropic's leverage is a reason to plan for multiple vendors in long-term contracts.
