Supercomputers

The ranking is a solved problem and we are not competing on it. What nobody publishes is the layer underneath: which company supplied each accelerator, CPU, fabric and cabinet; which corporate parent that supplier rolls up to after thirty years of consolidation; and which listed ticker therefore carries the exposure. Every system here is a node in a parts graph, not a row in a table.

Accelerator share, weighted by FLOPS

Machine-count share is the figure everyone quotes, and it understates whoever supplies the largest systems. Weighted by installed Rmax across the systems in this dataset, the picture is different. Supplier is rolled up to the corporate parent that owns it today.
