Amazon monetizing internal silicon externally compresses Nvidia's pricing power at the high end of AI training. Scale gap remains large — Nvidia run-rate cited ~$326B (TechCrunch) vs Amazon's hypothetical ~$50B standalone. Cannibalization risk dismissed by DeSantis: "There's so much underconsumption in AI. I'm not worried about it."
