Two clocks, one race

The whole thesis on a single scoreboard. One clock is the financing runway — how long the build-out's capital lasts before it must be repriced. The other is the productivity payoff — when AI finally shows up in the output. The cycle turns on which lands first. Drag the payoff date and watch it flip.

Financing runway (reprices ~2028) Productivity payoff lands The fragility gap

Scenario, not forecast. The runway window (~2027–2029) is where hyperscaler free cash flow turns negative and the AI debt issued in 2025–26 comes up for refinancing. The payoff range (2027 fast → 2037 slow) is the Lag Index fork. Drag to test any arrival date; the verdict is the gap between them.

How to read it

The bull case and the fragility case are the same picture

Almost every AI-cycle argument is really a claim about timing. The optimist says the payoff is near; the pessimist says the bill comes first. Put both on one axis and the disagreement becomes measurable: does the productivity payoff land before the financing has to be repriced? If it does, the long depreciation schedules and the debt were justified — a supercycle. If it doesn't, the capex reprices into a payoff that hasn't arrived — the fragility case, and the shaded gap is its size.

Clock 1 · the runway

How long the money lasts

Capex vs demand, circular financing, depreciation pulled forward, debt issued against returns that must show up on schedule. Instrumented on Capex Watch and Stranded Compute.

Clock 2 · the payoff

When the lag closes

Adoption is ~78%; realized productivity is ~5% of potential. The J-curve payoff arrives in 2027 — or 2037. Instrumented on The Lag Index.

The falsifiers

Payoff side: AI-attributable TFP turning up in the official series, broadening past a few industries — the runner gains.
Runway side: utilization climbing through 70%, or AI revenue growth overtaking capex growth — the runway lengthens, repricing recedes.
Against the bull: hyperscaler free cash flow turning negative on schedule and debt refinancing at higher rates — the runway shortens.
Against the bear: training silicon repurposing cleanly for inference, extending real asset life toward the booked schedule.

We track both clocks and revise in public when a falsifier moves.

Method & sources

The Race-o-meter is an interactive framing of two sourced instruments, not a forecast; the runway window and payoff range are scenarios you can move. Payoff fork (2027/2037) & the Lag Index: our Lag Index (Slok / Apollo; Kansas City Fed; BLS). Runway / financing pressure: Stranded Compute & Capex Watch (hyperscaler FCF and debt issuance via industry reporting; filings).
