PHYSIX OBSERVATION

The financing cost of AI infrastructure is shifting from a cheap-money era to risk-based pricing, and CoreWeave's bond yield approaching 15% is the market's first public warning about an AI debt bubble. When non-Magnificent-Seven stocks such as Oracle and Dell are sold off in a concentrated way, it shows investors are starting to distinguish the AI narrative from real debt-servicing capacity. For the industry, the model of piling up compute capacity by issuing high-interest debt will become increasingly hard to sustain, and capital will accelerate its concentration into cash-flow-healthy giants.
