What if Saudi Arabia floods the market to crush US shale?
Riyadh abandoning cuts to flood the market and discipline US shale sends Brent into the forties; short Brent, long fuel-levered airlines, and a steep contango are the trades, with disinflation a tailwind for duration. The textbook analogues are the Mar-2020 Saudi-Russia price war and the 1986 market-share war, both of which crushed flat price and energy equities. Transmission: cheap crude transfers income from producers to importing consumers/airlines; forward angle: US shale breakevens are lower and hedged in 2026, so Saudi must push prices deeper and longer than 1986 to force the same supply response.
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 0–6 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. Riyadh abandons cuts and floods the market to discipline US shale, sending Brent into the forties. The trigger decomposes into signed root‑shocks — Oil supply 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 LONG on ARM: its -7.2% history rests on off-channel, idiosyncratic windows (India RBI, palladium, Maduro) and a Feb-2024 IPO with no oil-crash sample — base rate meaningless here.
Historical precedent — what analogous events actually did
Across 6 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
Saudi market-share wars rare (2020,2014); Riyadh defending price in 2026, Brent-40s aggressive. A base‑rate‑anchored prior, continuously scored against what actually happens — not a forecast.
