Anthropic's infrastructure buildout—Amazon, Google, and AMD chips alongside Nvidia—signals that frontier AI labs no longer depend on a single supplier for training and inference. This diversification exposes Nvidia's vulnerability to scale-out competition and accelerates the viability of alternative architectures (TPUs, Trainium, MI300X) that were previously secondary. The constraint in AI is no longer model weights—it's kilowatts and the vendor lock-in that follows. Anthropic's hedge strategy shows the industry is actively resisting concentration.
