10 segmentsHow 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.
