Junk Bonds, Private Credit, and IPOs: AI's Financialisation Accelerates
This week's capital market activity represents a qualitative shift in how AI is financed, not merely a quantitative one. Anthropic is simultaneously pursuing a confidential IPO and a $35 billion private credit facility from Apollo and Blackstone — a structure that reveals the true compute cost of frontier model development cannot be satisfied by any single instrument. OpenAI's parallel IPO filing, one week behind, means public markets will soon be asked to price two companies whose combined implied valuation exceeds two trillion dollars, against revenue bases and monetisation timelines that remain contested. Citigroup's decision to raise its S&P 500 target explicitly citing an AI supercycle reflects how directly these listings are now conditioning broader equity market sentiment.
Below the headline lab valuations, the infrastructure debt layer is absorbing risk that its pricing may not fully reflect. Cipher Digital's $810 million junk bond issuance and Applied Digital's $5.2 billion hyperscaler lease both rely on offtake agreements as de facto credit enhancement — a structure that works until a major hyperscaler revises capex guidance. Fujikura raising cable prices and Marvell entering the S&P 500 confirm that the picks-and-shovels layer has transitioned from speculative growth to contracted pricing power, but the concentrated customer base of four to five hyperscalers remains an unpriced correlation risk across the entire credit stack.
