What if a missile on NATO soil triggers Article 5?
Article-5 invocation is the fattest tail in the book: VIX +19, mechanical risk-parity delever crushes Nasdaq and the S&P while only a modest oil premium builds (Russia crude still flows). The rhyme is Feb-2022 Ukraine — equities sold, then rebounded once the conflict stayed contained and no NATO direct-fire materialized. Forward angle: unlike 2022, European defense budgets are already mobilized, so a defense-spend bid (not just a flight to bunds) partly cushions EU equities — the dip is shallower and faster to fade than the gut-reaction VIX print implies.
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. A missile strikes NATO territory; Article 5 is invoked, raising direct NATO-Russia war risk. The trigger decomposes into signed root‑shocks — Geopolitical risk ▲ · Oil supply risk ▲ · Defense spending ▲ — 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 on MSTR/COIN/HOOD: +16-20% history is BTC-bull regime contamination from 2024-25 windows; a NATO-Russia hot-war flight-to-safety would crush crypto-beta, not bid it.
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
Direct NATO-Russia war/Article-5 invocation avoided through whole Ukraine war; deliberate escalation rare. A base‑rate‑anchored prior, continuously scored against what actually happens — not a forecast.
