One AI Supercycle - 10 Layers. 10 Tickers. Layer 1 — Power | $BE A single AI data center can consume 100–500MW. The US grid wasn’t built for this.

Power is the foundational constraint — before chips, before cooling, before anything else. Layer 2 — Substrates | $AXTI InP (Indium Phosphide) and GaAs (Gallium Arsenide) wafers are the raw material for photonic components — lasers, modulators, detectors. AXT Inc supplies these specialty substrates to the photonics supply chain. Demand is structurally rising as Co-Packaged Optics (CPO) and 1.6T transceivers scale. Tight supply, long qualification cycles, few alternatives. Layer 3 — Chips | $NVDA H100. H200. Blackwell. Each generation widens the moat rather than narrowing it.
