Kroll Bond Rating Agency assigned Anthropic a BB+ junk credit rating in June, prompting debate among Bitcoin advocates about traditional investments. The rating covered $4.4 billion in junior debt within Anthropic's $35 billion AI chip financing deal. The 10-year US Treasury yield crossed 5.3% in early October, reaching a 24-year high and raising questions about bonds as safe assets. Blockstream CEO Adam Back argues that every investment should be judged against the potential return from holding Bitcoin. However, Bitcoin offers no guaranteed returns, and government bonds still carry much lower default risk.
