AXT, Inc. — AI supply-chain exposure
The model reads AXT, Inc. primarily as a supplier in Infrastructure. Its strongest structural lever is Indium phosphide (system bottleneck #3), which it produces or supplies — genuine pricing power. Its largest modeled sensitivity is a shock at Indium phosphide (constraint β 35).

AXT makes compound-semiconductor substrates — the indium-phosphide and gallium-arsenide wafers on which laser and photodetector chips are grown. These are not the logic chips most people picture; they are the raw crystalline base for the optical components that move data as light between servers inside an AI cluster.
Its structural hook is upstream scarcity. Indium phosphide is a specialised material with few qualified suppliers, and it underpins the optical interconnects that datacenter networking increasingly leans on. As clusters scale and copper reaches its distance limits, demand for these substrates rises. The model places it deep in the materials layer — small and far from the model builders, but exposed to the optics bottleneck that lets tens of thousands of accelerators talk to each other.
