Keysight Technologies — AI supply-chain exposure

Keysight sits on the test-and-validation side of the chip world. It sells design-engineering software through Keysight EDA and the electronic test instruments used to prove that a design actually works before it ships. In AI infrastructure its tools are used to validate the fast interconnects the build-out depends on — 224G SerDes lanes, optical links and data-centre interconnect designs that have to hold signal integrity at extreme speeds.

The structural hook is that Keysight is gatekeeping infrastructure rather than a component. Every new high-speed standard has to be characterised and verified on instruments like its, so the company benefits whenever the industry pushes interconnect to a new speed grade — which AI is doing continuously. That is a durable, toll-taking position across the networking and chip layers, but it is enabling equipment sitting beside the value chain rather than a part inside the finished systems, which is why the model weights it modestly.
