Reflexive Demand in the AI Infrastructure Boom: Vendor Financing, Backlogs, & the CapEx-Cash Flow Imbalance (2022-2025)

Abstract

This paper examines whether the post-2022 AI infrastructure expansion represents genuine demand or a reflexive, vendor-financed cycle. Using financial data from Oracle, Microsoft, Amazon, Alphabet, and Nvidia, we document three interlinked dynamics: 1. A sharp rise in capital intensity (CapEx/OCF ratios above 1.0 for Oracle and rising steadily for Microsoft), 2. Exploding backlogs and Remaining Performance Obligations (RPO), largely long-dated and unmonetized, and 3. Heavy reliance on vendor financing and abundant credit markets that enable this expansion. We argue that the resulting feedback loop belief → financing → backlog → valuation → further financing, resembles the self-reinforcing mechanisms of the dot-com capex bubble, but with modern features such as AI-specific vendor financing and balance-sheet recycling of free cash flow by chipmakers like Nvidia. We contrast these dynamics with the 2008 financial crisis, noting that today's vulnerabilities stem not from household leverage but from corporate over-investment and deferred cash realization. Finally, we discuss early signs of sentiment cooling illustrated by the tech rally's recent loss of momentum and assess potential soft-and hard-landing paths for the AI sector.
