Hyperscaler capex now outpacing operating cash flow forces external debt financing, which raises the cost of AI infrastructure build-out and creates credit-market feedback that can slow deployment timelines independent of physical power or chip constraints.

◷ Share view, as of June 2026: confidence, rationales and priors are hidden. The questions, stances, claims, tests and evidence stay visible.

would falsifyAt least one of the Big 4 hyperscalers issues investment-grade debt directly attributed to AI capex financing within 12 months, and analyst models show OCF-capex gaps persisting for two or more consecutive quarters.
