Kroll Bond Rating Agency assigned Anthropic a BB+ credit rating in June, with the assessment becoming public in October. The rating, which sits one level below investment grade, indicates that lending to the company carries greater credit risk than higher-rated borrowers, typically requiring investors to demand higher returns as compensation.
The rating covered $4.4 billion in junior debt within Anthropic's $35 billion AI chip financing deal. That junior debt offered approximately 8.5% annual yield, compared with 5.75% on senior debt backed by Broadcom.
Anthropic's downgrade has highlighted broader concerns in financial markets beyond the AI sector. The 10-year US Treasury yield crossed 5.3% in early October, reaching a 24-year high. Higher yields mean existing bonds lose market value, and investors selling before maturity can suffer losses even on government debt.
The development has prompted scrutiny of the traditional 60/40 investment portfolio, which allocates 60% to stocks and 40% to bonds for stability. ParaFi investor Jeff Park flagged these market dynamics as particularly significant for portfolio construction.
Bitcoin advocates have seized on the opportunity to argue for reconsidering safe-haven assets. Blockstream CEO Adam Back suggested that Bitcoin should serve as the benchmark against which all investments are measured. However, Bitcoin's volatility presents a complicating factor in such comparisons, as government bonds carry substantially lower default risk while Bitcoin offers no guaranteed returns.
Bitcoin analyst Willy Woo cautioned that an economy centered on Bitcoin could experience slower growth if debt becomes harder to service. Meanwhile, bond exchange-traded funds have attracted record inflows, indicating continued investor demand for fixed-income assets despite recent market pressures.
