PHYSIX OBSERVATION

Anthropic's valuation pullback reflects that after AI companies return to normal from hypergrowth, capital markets no longer buy in unconditionally. Slowing revenue growth, weak growth in customer spending, rigid compute costs, plus regulatory and governance disputes, have narrowed the IPO window. For the industry, this may be a signal that the AI valuation bubble is starting to deflate, and future financing will place more weight on a path to profitability rather than pure growth rate.
