Anthropic rated junk at BB+ as it chases $2T IPO
What's the deal? Kroll Bond Rating Agency (KBRA) assigned Anthropic an issuer rating of BB+ in June 2026 — one notch below investment grade — based on limited financial information from the company. The rating action, previously unreported, was broken by the Financial TimesDealroom has a profile for this one. Try Dealroom → on October 16, 2026.
Why now? The rating came ahead of a $35 billion chip financing led by Apollo, in partnership with Blackstone, as part of Broadcom's AI XPV Platform. The deal is funding a rapid expansion of Anthropic's compute capacity — more than 1GW of training and inference infrastructure from mid-2026.
Follow the money: About $4.4 billion of junior debt in that financing exposes lenders directly to Anthropic's credit risk and also drew a BB+ rating from KBRA, with a stable outlook. That junior tranche sold at a yield of about 8.5%, while senior debt — guaranteed by Broadcom — carried an interest rate of 5.75%.
What could go wrong? KBRA reportedly had no free cash flow or EBITDA figures to build a full financial model for Anthropic. Instead it relied on a risk-score-based approach rather than a standard credit model.
What's the endgame? Anthropic is separately pursuing a potential IPO that could value the company near $2 trillion. A sub-investment-grade rating underlines the gap between that ambition and the financial transparency lenders currently have.
The signal: A near-$2 trillion IPO candidate carrying a junk rating captures the AI sector's central tension — vast valuations resting on compute spending that outpaces proven, disclosed financials.
