What if a short-volatility blow-up sends the VIX soaring again?
A short-vol/structured-product blowup is the cleanest mechanical cascade in the book: a violent VIX spike detonates vol-target and risk-parity books, dumping Nasdaq, tech and semis, blowing out HY credit and dragging MSTR/BTC. This is Feb 2018 Volmageddon (XIV to zero) almost literally. Forward angle: the buffer/defined-outcome ETF and dispersion-short complex is far larger today than the 2018 VIX-ETP stack, so the dealer-gamma feedback can overshoot the original episode.
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. A short-volatility / structured-product blowup spikes the VIX violently. The trigger decomposes into signed root‑shocks — Volatility (VIX) ▲ · 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 VIX: the -16% realized is measurement artifact — windows anchor on the post-spike COVID/Evergrande mean-reversion, not the spike itself; a short-vol blowup IS the violent VIX gap-up, not the decay.
Historical precedent — what analogous events actually did
Across 27 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
Short-vol blowups recur (2018, 2020); structured-product growth keeps tail live over 1-3y. A base‑rate‑anchored prior, continuously scored against what actually happens — not a forecast.
