Among known chip types:\n- **NVIDIA H100 SXM5 80GB**: 77 systems (16.0%)\n- **NVIDIA A100**: 73 systems (15.1%)\n- **NVIDIA V100**: 32 systems (6.6%)\n- **NVIDIA Tesla V100 SXM2**: 14 systems (2.9%)\n- **NVIDIA GH200**: 11 systems (2.3%)\n\n### Country Distribution\n- **China**: 188 systems (39.0%)\n- **United States**: 119 systems (24.7%)\n- **Japan**: 25 systems (5.2%)\n- **France**: 14 systems (2.9%)\n- **South Korea**: 12 systems (2.5%)\n\nChina and the US together account for nearly two-thirds of all AI supercomputers in the dataset.\n\n### Certainty Level\n- **Confirmed**: 401 systems (83.2%)\n- **Likely**: 81 systems (16.8%)\n\nThe vast majority of entries are confirmed rather than speculative.\n\n### Sector\n- **Private**: 274 systems (56.8%)\n- **Public**: 149 systems (30.9%)\n- **Public/Private**: 50 systems (10.4%)\n\nPrivate sector dominates AI supercomputer ownership.\n\n### GPU Supplier (Primary)\n- **NVIDIA**: 249 systems (51.7%)\n- **Anonymized**: 190 systems (39.4%) - supplier information withheld\n- **AMD**: 17 systems (3.5%)\n- **Unknown**: 10 systems (2.1%)\n- **Google**: 9 systems (1.9%)\n\nNVIDIA is the clear market leader among disclosed suppliers, though a significant portion of systems have anonymized supplier information.\n\n### Universal Values\n- **Status**: All 482 systems are marked as \"Existing\"\n- **Single cluster?**: All 482 systems are marked as \"true\"\n\nThese columns show no variation across the dataset.",
