The AI value chain distributes invested capital across six interconnected tiers, from physical power generation down to end applications. Power demand scales with deployed clusters and data center cooling efficiency, computed as clusters divided by one hundred times zero point one two times PUE. Selecting the energy bottleneck scenario cuts power capacity to four point five gigawatts, choking operational GPU factor and driving utilization to maximum. Constrained token throughput and layer ROIC update immediately, revealing how physical infrastructure limits dictate downstream application returns.
