What if eldercare robots are deployed nationwide?
Japan mandating eldercare robots validates a model US insurers copy — a clean robotics-productivity tailwind filling a genuine labor shortage; long Nvidia/edge-AI and robotics names without the displacement-unrest overhang. Rhymes with the May-2023 Nvidia capex-wave. Forward: Japan's demographics (world's oldest population) make it the first real at-scale humanoid-care market — the export read flows to Japanese robotics (Fanuc, Cyberdyne) as much as to US GPUs.
how we built this number — every step
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 1–3 years 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-on shock. Japan mandates care-robots in nursing homes amid worker shortage, validating a model US insurers rush to copy. The trigger decomposes into signed root‑shocks — Labor shortage ▲ · Robotics productivity ▲ — 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.

Probable recommendation
Why we may diverge from history
Trust the cascade on AMD/QCOM/ASML; the negative history reflects 2024 jobs-report and AI-capex-doubt selloffs, not eldercare-robot silicon demand — the analogue windows cluster in one rate regime, biasing the base rate.
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.

Why this probability
Japan care-robot push real but a national mandate US insurers rush to copy in 1-3yr is aggressive; adoption slow. A base‑rate‑anchored prior, continuously scored against what actually happens — not a forecast.
