Kindleberger documented structurally identical mechanisms in the South Sea Company's share-buy-back schemes of the 1720s, in the cross-holdings of Japanese keiretsu before the 1990 crash, and in the SPV structures of the pre-2008 credit bubble. The sophistication of the mechanism bears no relationship to its sustainability. Each instance shared the feature that Kindleberger identified as characteristic: the revenue generated by the loop is real in an accounting sense but circular in an economic sense. Money flows between participants, generating reported revenue at each step, but the ultimate source of that money is external capital raised on the assumption that the reported revenue indicates genuine economic activity.
The structure is not, in itself, fraudulent — it is a standard feature of immature technology markets where participants are simultaneously customers and suppliers. The distinction between healthy vendor relationships and pathological financing loops is a matter of degree, not kind. At some volume, the circular component overwhelms the non-circular component, and the external capital required to sustain the loop exceeds the external revenue that eventually validates it. The critical question is whether the loop can transition to self-sustaining external revenue before the external capital that sustains it becomes unavailable.
The regulatory response that Kindleberger's framework implies is transparency. When the revenue supporting a company's valuation is substantially composed of purchases by other companies within the same financing circle, this fact should be disclosed with the same rigor that financial institutions disclose counterparty exposures. The circular financing of the AI industry represents a systemic risk invisible to outsiders unless disclosure requirements make it visible — and the failure to disclose it perpetuates the information asymmetry between insiders and outsiders that Kindleberger identified as the primary mechanism through which outsiders are disadvantaged.
The structure was documented in financial commentary throughout late 2025, with specific reference to the Nvidia-OpenAI-Oracle loop and related arrangements involving Microsoft, Amazon, and the major AI platform companies.
Historical precedent. South Sea Company, Japanese keiretsu, pre-2008 SPVs — the structure recurs across three centuries.
Not fraud but scale. Healthy vendor relationships become pathological when circular volume dominates.
External capital dependency. The loop requires ongoing external capital raised on projections the loop itself generates.
Transparency as remedy. Disclosure requirements would reduce the information asymmetry.
