What if autonomous AI trading agents trigger a market flash crash?
An autonomous-agent flash event is a pure vol/liquidity shock: a VIX spike forces mechanical risk-parity/vol-target deleveraging into Nasdaq, the S&P and BTC, with the spill into credit spreads the tell that it's real. Rhymes with the May-2010 Flash Crash and the Aug-2024 yen-carry unwind (intraday VIX 65) - both v-shaped once liquidity returned. Forward angle: circuit breakers and kill-switches mean the realized drawdown is usually smaller than the intraday print, so fade the panic in index, not in single-name microstructure casualties.
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. Autonomous AI trading agents cause a catastrophic market flash-crash/manipulation event. 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's BTC/MRVL/AVGO shorts: history's gains are regime-contaminated by 2020-COVID and 2024 carry-unwind rebounds and BTC's structural bull — an AI-driven flash crash hits chips and crypto first, not last.
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.
