What if a supervolcano caldera starts showing signs of unrest?
Caldera unrest (Campi Flegrei / Yellowstone-type deformation) is a slow-burn fear trade: it bids ag (wheat/corn on crop-cooling tail risk) and dents risk appetite modestly, but eruption is not imminent, so it stays a tail premium not a position. The 1980s Campi Flegrei bradyseism crises are the analogue — years of unrest, no eruption, no durable market impact. The cascade's 'water-stress hits fabs → semis down' leg is a spurious artifact of the climate_supply root; the root itself (crop supply) is correct, the semi link is not.
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-off shock. Ground deformation and quakes at a supervolcano caldera spark eruption fears, threatening aviation and regional agriculture. The trigger decomposes into signed root‑shocks — Climate/crop supply ▲ · Risk appetite ▼ — 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
Historical precedent — what analogous events actually did
Across 19 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
Caldera unrest signals do occur (Campi Flegrei); eruption-fear episode plausible over 1-3yr. A base‑rate‑anchored prior, continuously scored against what actually happens — not a forecast.
