Key Takeaways
- • Kroll Bond Rating Agency (KBRA) assigned Anthropic a BB+ rating in June, one notch below investment grade, though the assessment only became public in October.
- • The rating covered $4.4 billion of junior debt within Anthropic's $35 billion AI chip financing deal, which offered roughly 8.5% annual yield versus 5.75% on Broadcom-backed senior debt.
- • The 10-year US Treasury yield crossed 5.3% in early October, a 24-year high, eroding the perceived safety of government bonds.
- • Bitcoin advocates, including Blockstream CEO Adam Back and ParaFi's Jeff Park, are using these developments to challenge the traditional 60/40 portfolio.
Summary
The rating covered $4.4 billion in junior debt within Anthropic's $35 billion AI chip financing arrangement. That tranche offered roughly 8.5% in annual yield, compared with 5.75% on senior debt backed by Broadcom, highlighting the risk premium attached to subordinated AI infrastructure financing.
The article argues the implications extend beyond a single issuer. US government borrowing costs are climbing, with the 10-year Treasury yield crossing 5.3% in early October, a 24-year high. Because higher yields depress the market value of existing bonds, investors selling before maturity can incur losses even on government debt, challenging conventional assumptions about safe assets.
ParaFi investor Jeff Park has questioned the traditional 60/40 portfolio allocation. Blockstream CEO Adam Back has argued that every investment should be judged against the potential return from holding Bitcoin. The article notes that Bitcoin's volatility complicates that comparison, since government bonds still carry far lower default risk while Bitcoin offers no guaranteed return. Bitcoin analyst Willy Woo has 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 continue to value fixed-income assets.
Whether the Anthropic rating persuades traditional allocators to reconsider their fixed-income and Bitcoin positioning remains an open question.
