The scarce part of an 800G/1.6T link is often the laser — EML and CW lasers grown on indium-phosphide wafers that few fabs can make at volume.

InP substrate→Epitaxy→EML / CW laser→Module

What would prove us wrong. Weakens if laser ASPs fall sharply while transceiver volumes rise — the choke would have moved.

Small markets with outsized importance: gallium for GaN and InP, germanium for optics, antimony for defence. China has restricted exports.

By-product→Refining→Wafer / alloy→Device

What would prove us wrong. Weakens if Western by-product recovery scales fast enough to erase price premia.
