What if the Nipah virus reaches a dense Asian megacity?
Direct chain: a 70%-fatality Nipah outbreak in an Asian megacity sparks lockdowns — regional mobility/oil-demand hit, gold and duration bid, biotech vaccine names (Moderna-type platforms) spike. Rhymes with SARS-2003's Asia-localized demand shock plus the COVID-2020 haven bid. Because fatality is high but transmissibility (vs. COVID) is the open question, the tail is bimodal — the moderate pandemic 1.0 / no-recession-root calibration sensibly stops short of the full global-recession cascade.
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. Nipah encephalitis virus jumps to a dense Asian megacity with 70% fatality, sparking lockdowns and biotech vaccine scramble. The trigger decomposes into signed root‑shocks — Pandemic shock ▲ · 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 measured history on UAL/DAL: -14% across pristine COVID pandemic analogues kills the cascade's 'LONG/up'; the NVDA/AMD/MRVL 'up' is just 2020 V-recovery rebound, off-channel for a lethal outbreak.
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
Nipah urban megacity jump with 70% fatality extremely rare; outbreaks stay small, rural. A base‑rate‑anchored prior, continuously scored against what actually happens — not a forecast.
