Anthropic, the company behind Claude, has received a junk credit rating, raising questions about the risks behind the AI investment boom. Bitcoin advocates see a much bigger problem emerging in traditional finance.
Kroll Bond Rating Agency (KBRA) assigned Anthropic a BB+ rating in June, although the assessment only became public in October.
BB+ sits one level below investment grade. In simple terms, it means lending to the company carries greater credit risk than lending to higher-rated borrowers.
Investors therefore demand higher returns to compensate.
The rating also covered $4.4 billion in junior debt within Anthropic’s $35 billion AI chip financing deal. That debt offered roughly 8.5% in annual yield, compared with 5.75% on senior debt backed by Broadcom.
But why should Bitcoin investors care about an AI company’s credit rating?
Why Anthropic’s Rating Has Sparked a Bitcoin Debate
The issue extends beyond Anthropic. US government borrowing costs are also climbing, challenging how investors think about safe assets.
The 10-year Treasury yield crossed 5.3% in early October, reaching a 24-year high.
Higher yields mean existing bonds lose market value. Investors selling before maturity can suffer losses, even on government debt.
ParaFi investor Jeff Park highlighted these developments, questioning the traditional 60/40 portfolio, which allocates 60% to stocks and 40% to bonds for stability.
Blockstream CEO Adam Back went further.
Bitcoin is the hurdle rate.

His argument is that every investment should be judged against the potential return from holding Bitcoin.
However, Bitcoin’s volatility complicates that comparison. Government bonds still carry much lower default risk, while Bitcoin offers no guaranteed returns.
Bitcoin analyst Willy Woo has also warned that a Bitcoin-based economy could face slower growth as debt becomes harder to repay.
Meanwhile, bond ETFs have attracted record inflows, suggesting investors still value fixed-income assets.
Anthropic’s rating has given Bitcoin supporters fresh ammunition. Whether that argument persuades traditional investors remains an open question.
