The marginal dollar at every layer earns less. Except the network.
Capital is still flooding the AI stack, but the marginal dollar earns less than the prior dollar at every layer except one. Hyperscalers are deploying ~$700B of 2026 capex against ~$120B of AI-attributable revenue — a ratio that gets tested when Microsoft, Google, Meta, and Amazon all print Q1 between April 29 and May 6. Frontier labs are committing forward compute at multiples of their disclosed revenue. The on-prem floor moved up sharply this week with DeepSeek V4 (open weights, frontier-class on coding), reshaping enterprise procurement: the question is no longer whether to self-host frontier capability, but which workload to move and on what fabric. The durable winner of the buildout is the network and interconnect layer that connects cloud, neocloud, and on-prem for hybrid AI — the only layer where pricing power compounds rather than compresses.

The methodology.

— Every quantitative claim is graded 1–5 on source quality. Anything 2 or below is flagged as noise.
— Every prediction is falsifiable, time-bounded, and tied to a specific signal. Future issues score them hit, miss, partial, or pending.
— Twelve levers are tracked week over week, with thresholds that materially change the read.
— All sources are public. Independent analysis only.
