A field guide

How to read this map

The map groups the AI ecosystem into power and facilities, the silicon supply chain, and intelligence. Select a layer to see what feeds it and what it supplies. Each theme opens into specific market segments and the companies working in them. Search for a company to highlight its footprint; role counts show the number of segments it serves in each theme.

Switch the tile indicators between heat and spend to compare themes on a five-point scale. Heat measures supply pressure and attention; spend estimates annual AI-driven demand. Exposure measures how much of a company’s business depends on a segment or on AI overall.

Compiled from public sources as of Sep 18, 2026, with sources listed per segment and numbers presented as editorial estimates. Foreign and private companies appear without stock pages. This is a map, not advice.

Leader
Sets the pace in this segment.
Major
A substantial, established participant.
Challenger
