What if Russian and NATO submarines square off under the Arctic ice?
An Arctic NATO-Russia submarine standoff is a low-intensity tail (VIX +8.8): primes firm, broad equity softens modestly, no oil channel. Closest analogue is Cold War GIUK-gap cat-and-mouse — strategically tense, never market-moving. The actionable read is minimal: the only durable leg is a structural bid to ASW/naval-defense names and, longer-term, Arctic shipping/LNG re-routing optionality; the equity drawdown is not investable signal.
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 6–18 months 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. Russian and NATO submarines face off under melting ice over contested Arctic shipping lanes. The trigger decomposes into signed root‑shocks — Defense spending ▲ · Geopolitical risk ▲ — 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's SHORT on COIN/MSTR: the +13-14% realized came from Rising Lion and Wagner windows during the BTC structural bull — regime contamination, not an Arctic naval risk-off signal.
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.
