What if humanoid robots fall below $20,000 and go mainstream?
A sub-$20k price point is the humanoid 'iPhone moment' — mass adoption pulls forward inference-silicon demand, lifting Nvidia/semis and Tesla, with disinflation as the macro kicker. Closest analogue is the post-May-2023 Nvidia surge and the broader 2023-24 AI-capex rerating. Forward angle: a price crash that cheap implies Chinese-scale manufacturing, which simultaneously compresses Western humanoid margins — so the same shock is bullish silicon/platform but bearish hardware-only assemblers, a split the uniformly-bullish cascade glosses over.

What it would mean
If this plays out, it is a risk-on shock. A sub-$20k humanoid-robot price point triggers mass adoption across services and homes. The trigger decomposes into signed root‑shocks — Robotics productivity ▲ · Job displacement ▲ — which propagate through our causal graph to the markets below.
