What if Russia detonates a tactical nuclear weapon in Ukraine?
A Russian battlefield nuke breaks the post-1945 taboo — the deepest risk-off in this set: VIX up ~20, Nasdaq -9, crypto and credit hammered, only primes green. No clean analogue exists; the 1962 Cuban Missile Crisis is the reference point, where the sell-off was sharp but the V-shaped recovery was even faster once de-escalation began. Forward angle: with no Cold-War-era circuit breakers and 24/7 crypto, the initial air-pocket would be more violent and gold/Treasuries the only real haven bid.
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. Russia detonates a battlefield tactical nuclear weapon, shattering the post-1945 nuclear taboo. The trigger decomposes into signed root‑shocks — Defense spending ▲ · 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 SHORT: COIN/MSTR's +13% reflects Bitcoin's structural bull, not a broken nuclear taboo; the JPM/SPX sub-3% 'history-up' is noise — first battlefield nuke since 1945 is decisively risk-off.
Historical precedent — what analogous events actually did
Across 38 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
Nuclear taboo unbroken since 1945; even at war's worst Russia held back; structural tail. A base‑rate‑anchored prior, continuously scored against what actually happens — not a forecast.
