What if an undetected meteor airbursts over a populated region?
A populated-area airburst with kiloton force shatters windows and spikes insurance/defense — the actionable move is a one-to-two-day VIX pop and risk-off in high-beta crypto/Nasdaq, plus a short-lived bid in defense and reinsurance-adjacent names. Chelyabinsk (Feb-2013) is again the template: locally destructive, financially negligible. Skeptical take: with no second strike, the deleveraging cascade self-reverses fast; the only edge is fading the panic, not chasing it.
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 Tail risk 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 undetected meteor airbursts over a populated region with kiloton force, shattering windows and rattling insurance and defense markets. The trigger decomposes into signed root‑shocks — Geopolitical risk ▲ · 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
Why we may diverge from history
Trust the cascade shorts: COIN/MSTR/SOL history is BTC-bull regime contamination from Iran/Wagner/tariff windows, and RTX's -3.6% is the 2020 oil-war crash, not a meteor-airburst defense-demand and risk-off shock.
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
Chelyabinsk-class airbursts recur every decade-ish; populated-area kiloton strike low-probability tail. A base‑rate‑anchored prior, continuously scored against what actually happens — not a forecast.
