What if mass-produced solid-state batteries double EV range?
First mass-produced solid-state cells re-rate EVs and storage, but the +2% NVDA print conflates a battery milestone with AI-GPU demand; the cleaner trade is Tesla/automaker and battery-materials repricing, not semis. Rhymes with the 2023 hype around Toyota's solid-state roadmap that lifted EV names on promise, not volume. Skeptical: 'mass-produced' solid-state has slipped for a decade — yields and dendrite control are the gate, so size any equity move as narrative until shipment data confirms.
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. A major maker ships the first mass-produced solid-state batteries, doubling EV range and re-rating storage. The trigger decomposes into signed root‑shocks — 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 long on ASML/AMD: history's negatives are Nvidia/TSMC chip-event and jobs-report windows — an AI-capex-cycle sample, off-channel; a solid-state EV/storage re-rating is a different catalyst those semiconductor analogues don't measure.
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
Solid-state mass production keeps slipping; first real ships possible but range-doubling claim aggressive. A base‑rate‑anchored prior, continuously scored against what actually happens — not a forecast.
