What if OPEC+ fractures and Saudi Arabia launches a price war?
An OPEC+ break-up with Saudi flooding the market collapses Brent/WTI, crushing energy equities and breakevens while fuel-levered airlines (UAL) rally on lower input costs. The textbook analogue is the Mar-2020 Saudi-Russia price war that halved crude in weeks, and the 2014-16 'defend share' crash. Forward angle: a deflationary oil shock would also pull forward Fed cuts, so it reads risk-on for duration and consumers even as the energy complex is liquidated.
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-on shock. OPEC+ cohesion collapses; Saudi Arabia floods the market in a price war. The trigger decomposes into signed root‑shocks — 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 BTC: the -6.8% history is the 2020 Saudi-Russia price-war COVID circuit-breaker crash — a liquidation regime, not an oil-glut risk-on tape; sample is regime-contaminated, fade 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
Full cohesion-collapse price war rare; OPEC+ disciplined, share spats stay contained. A base‑rate‑anchored prior, continuously scored against what actually happens — not a forecast.
