Kimchi Stew, Part Three closes the trilogy by going one financial-engineering layer deeper than Parts One and Two walked. Parts One and Two named individual financial perversions across the AI capex cycle — the Anthropic accounting smell on the run-rate figures, the back-fill question on the Anthropic-to-xAI compute commit, the IPO concentration as financing signal, the substrate-tiering monetizing the Opus 4.8 regression, the vendor-deflection counter to the procurement-model-is-broken framing. Part Three threads all of those into a single mechanism — the stake-and-multiple loop, where hyperscaler equity stakes in AI labs are marked to fair value through profit and loss each quarter, the paper appreciation gets price-to-earnings multiple expansion as if it were operating earnings, and the entire financial-engineering layer becomes a constituency for the AI capex flywheel continuing regardless of operational reality. Three external voices anchor the editorial work: Upton Sinclair (1934) on why the participants in the loop cannot understand the mechanism; John Kenneth Galbraith (1955) on the bezzle dynamics of booms and crashes; Mike Green of Simplify Asset Management on the contemporary circular-financing structure being identical to dot-com vendor financing. The trilogy close extends the canonical "Do Your Own Work" doctrine from the model layer down to the financial-engineering layer.
