The government just banned Chinese optical components, sending US makers of those parts soaring. At the same time, the AI data-center build-out is so strong that heavy-equipment maker Caterpillar just posted record revenue and raised its forecast. These two stories together show the AI boom is creating massive demand for both the digital networking gear and the physical infrastructure behind data centers.

## Idea

The US ban on Chinese optical components is a direct transfer of market share to domestic suppliers — these companies make the lasers and transceivers that connect servers inside data centers. But that demand doesn't exist in a vacuum; it's driven by the same AI infrastructure spending wave that just pushed Caterpillar to record revenue, because every new data center also needs heavy power and cooling equipment. With CAT's record backlog confirming the build-out is accelerating and the optics ban guaranteeing pricing power for US-based component makers, the trade captures both the digital and physical sides of the AI capex supercycle.
