AI cooling stocks

As racks pack more accelerators into the same footprint, the heat they throw off outruns what air alone can carry — so the AI build-out is shifting to liquid cooling: cold plates, coolant distribution and, increasingly, the water rights to run it all. Cooling is now a gating item on how quickly new capacity comes online, not an afterthought, and the companies that supply the thermal stack sit directly in the path of every high-density deployment. Water availability adds a real, local constraint on where the largest sites can be built at all. This theme groups the names most exposed to the cooling parts of the AI value chain.
