Common questions

What is AI infrastructure?

AI infrastructure is the physical and digital foundation that makes artificial intelligence work: the chips that do the maths, the power that runs them, the data centres that house them, the networks that connect them, the data that feeds them and the platforms that host the models. Every AI product you use sits on top of this stack, and most of the money spent on AI flows down into it.

Which companies make up AI infrastructure?

No single company covers the whole stack. Chip designers and foundries, power producers, data centre operators and clouds, networking and optical suppliers, data platforms and model providers each own one part. This page groups the most notable ones by the layer they operate in.

Is this investment advice?

No. It is an educational map of who does what. Company positions change quickly, so check current filings and news before drawing any conclusions.
