China Controls the Magnets, We Control the Models
Executive Synthesis On one side, American firms are winning the model war. On the other, Beijing is winning the parts war. And it is the parts war that will ultimately determine who deploys autonomous systems at scale. Start with the hardware choke point. McKinsey's recent analysis lands on a finding that deserves far more boardroom attention than it is getting: the constraint on humanoid robotics deployment is not the AI model stack. It is magnets. Gearboxes. The sensors embedded inside actuators. China controls approximately 70% of the global supply chain for those components. This is not a theoretical dependency. It is the physical substrate that American robotics ambitions are literally built on. Every Kawasaki Kaleido demo, every Hyundai MobED unveiling, every defense robotics agreement the Department of War signs with its seven AI company partners, runs through that same supply chain. The strategic irony is considerable: Washington is betting on autonomous military systems ...
