Getting the heat back out
Every watt that goes into a rack comes out as heat, and air stopped being enough somewhere around the current generation. Vertiv is shared with the grid basket; the two Taipei listings are where the thermal modules actually get built.

What the category earns
Growth leads here, and it is the median across members rather than a total — a per-company growth rate does not care what currency the company reports in, so Samsung and Micron count equally. Revenue levels can only be added within one currency, so the totals below cover the members reporting in USD and say how many that is.
Years are labelled by the calendar year each company's fiscal year ends in. Those calendars do not line up — Nvidia's 2026 ended in January — and this does not pretend otherwise.
