A what‑if from the future

What if a rare-earth-magnet bottleneck stalls the humanoid-robot ramp?

An actuator / rare-earth-magnet bottleneck caps the humanoid ramp: Nvidia, TSMC and the semi complex sell as the deployment story stalls, and the disinflation thesis pauses. Closest analogue is the Oct-2024 ASML bookings-miss chip-equipment shock, which exposed how a single supply constraint repriced the complex. Transmission runs through China's ~90% grip on processed rare earths/NdFeB magnets. Forward angle: the real chokepoint is magnets and precision actuators, not GPUs — the cascade over-weights silicon; the cleaner short is the assemblers and the cleaner long is rare-earth supply ex-China.

The class rate is measured from our dated, sourced event library (decade-normalized Poisson — the full table is public at base_rates.json). The variant’s share within its class is the analyst’s editorial call, published so you can audit it. A wider range means thinner precedent. Full recipe: methodology · scored at Reality Check.

The butterfly cascade

How this trigger trickles across markets, left → right — the root shock, its first‑order moves, then the ripple effects. Drag any node; tap a market for its real price history.

Resolution timeline — how this probability is moving

Our model's odds (gold) over time vs the crowd's (Polymarket, blue), from the past toward the 6–18 months horizon. Each dot is a real macro event that nudged the probability — green pushed it up, red pushed it down. Tap a dot for the source. The gold path is an illustrative reconstruction anchored to today's estimate — real dated events, not a live re-estimate history.

What it would mean

If this plays out, it is a risk-off shock. An actuator / rare-earth-magnet bottleneck constrains the humanoid-robot ramp. The trigger decomposes into signed root‑shocks — Robotics productivity ▼ · Semiconductor supply risk ▲ — which propagate through our causal graph to the markets below.

If it happens — the markets it would move

Biggest moves first. Projected moves are cascade-model priors; hist A–B% = what comparable past events actually did (measured abnormal returns), and model prior · unmeasured marks markets with no analogue backing yet. Tap any market for its price history.

Historical precedent — what analogous events actually did

Across 40 analogous events (overlap‑weighted), as abnormal returns — market beta stripped, so it's the event's own effect, not the market backdrop. Shown at 20 days (persistent) and 5 days (immediate); ↺ fades = the two horizons disagree. Confidence = consistency × sample × significance.
