SpaceXAI’s Colossus 2 has the largest deployed entry, with 550,000 GB200/GB300 GPUs. Its additional 440,000 announced GPUs are excluded from that deployed count.
The count is based on the operator’s reported figures, not an independent hardware audit. The index is a selected inventory; its rows include both individual clusters and combined fleets, and chip counts do not measure usable computing performance.
Citation estimates use inputs through September 1, 2026; fleet counts have an October 1, 2026 cutoff. The research-topic sample covers January 1 to June 1, 2025. See each answer for its period and limitations.
