The humanoid supply chain turns policy: the part you can't buy in the US
From the Robots digest for 2026-10-03
What happened: three pieces in window: (1) "The AI-robotics stock list has a shipping problem — the real bottleneck is a part you can't buy in the US" (ainvest): Teradyne derives <10% of revenue from robotics while "pure-plays" like Symbotic carry concentration risk; (2) MarketWatch: to win the humanoid race, the US needs a critical machine component it doesn't have a supply chain for; (3) "US moves to fix humanoid supply-chain gaps" — FCC import restrictions meeting US-maker warnings of actuator and rare-earth gaps that could triple costs.
What's genuinely new: the import-ban thread's second-order effect is now explicit — the ban is supposed to force onshoring, but the onshoring bottleneck (actuators, rare earths) is the part nobody can buy domestically, and the cost math (tripling) is out in the open. The stock-list piece adds the market-structure irony: most listed "robotics" names aren't materially robotic.
