Maybe compute is the real moat (chinese possibly skip around it with distillation), xai is buildouts have been insanely fast (colossus 1 - 100,000 H100 GPUs brought online in 122 days lol) so maybe that explains them catching up
asked grok to give a compute estimate for each:
- SpaceX / xAI: ~1.4 GW (owned Colossus clusters)
- OpenAI: ~2–3 GW (mostly rented/cloud)
- Anthropic: ~1.5–2.5 GW (multi-cloud + xAI lease)

chatgpt estimates a lower: - OpenAI: ~1.5M H100-eq ± ~0.8M - Anthropic: ~1.4M H100-eq ± ~0.7M - SpaceX/xAI: ~0.6M H100-eq ± ~0.3M
but it felt obligated to mention that "for single tightly interconnected NVIDIA training clusters, SpaceX/xAI has been unusually strong."
