What if the Saudi crown prince is assassinated?
MBS's assassination destabilizes OPEC policy: Brent leads WTI sharply higher on a Gulf supply-risk premium, the refined-product crack and breakevens rise, and VIX spikes. Closest analogues are the Sept-2019 Abqaiq attack (Brent +15% in a day) and the 2020 Saudi-Russia price war. Transmission: Saudi is the swing producer with most of the world's spare capacity, so a policy vacuum threatens the marginal barrel. Forward angle: succession uncertainty over the production-cut framework could swing either way (defend price vs. grab share) — the asymmetry is to the upside given depleted spare capacity elsewhere.
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. The Saudi Crown Prince is assassinated, destabilizing OPEC oil policy. The trigger decomposes into signed root‑shocks — Geopolitical risk ▲ · Oil supply 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 LONG on CL/BRENT: history's -7% comes from supply-glut analogues (OPEC-2014, Saudi-Russia-2020 price wars) whose causality is inverted versus an MBS-death OPEC-disruption that removes barrels, not adds them.
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.
