A what‑if from the future

What if China attempts a decapitation strike on Taipei?

A decapitation strike on Taipei is the same fab-loss tail as full invasion but faster and more chaotic: VIX +20, Nasdaq -9, TSMC -6 as markets price a leadership vacuum plus chip-supply seizure. Like an Israel-on-Iran first-strike (June 2025) compressed onto the world's most critical supply chain. Transmission hits Apple, Nvidia, and the entire fabless ecosystem simultaneously. Forward angle: a rapid-capitulation gambit could paradoxically shorten the disruption if fabs survive intact, so the V-shape risk is real.

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 Tail risk 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. China attempts missile and special-forces decapitation of Taiwan's leadership to force rapid capitulation. The trigger decomposes into signed root‑shocks — Geopolitical risk ▲ · Risk appetite ▼ · Semiconductor 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

If the scenario above plays out, the probable cross‑asset positioning → a scenario‑conditional read, not personalized investment advice
Cash / hedgeRaise cash and hold the long hedges above; this scenario is net risk-off.
For a common-man portfolio: A typical stock-heavy portfolio is at risk. Consider trimming equities, raising cash, and a small gold hedge.

Why we may diverge from history

Trust the cascade short on MSTR/JPM/XLF: a Taipei decapitation tail-risk has no clean analogue — the +11%/+3.8% windows are tariff-relief and mutiny bounces, structurally incomparable to a system-shock kinetic strike.

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

Decapitation strike on Taipei is novel high-end first-move; tail risk, very unlikely. A base‑rate‑anchored prior, continuously scored against what actually happens — not a forecast.
