What if a retail buying frenzy drives a parabolic melt-up?
A leveraged retail options/meme frenzy produces a parabolic melt-up — the trade is long the highest-gamma, highest-beta names (Solana, meme single-stocks) as dealer hedging chases price up, until it reflexively reverses. Rhymes with Jan-2021 (GME/AMC) and the 2024-25 crypto/retail melt-ups: vertical gains, then violent mean-reversion. Skeptical: melt-ups are unstable and end in capitulation (see scenario 1188); the durable lesson is to fade exhaustion, not chase. Roots (max risk_appetite + crypto_liquidity) are well-specified for a risk-on squeeze.
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. A leveraged retail buying frenzy in single-stock options and meme names produces a parabolic melt-up detached from fundamentals. The trigger decomposes into signed root‑shocks — Crypto liquidity ▲ · 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 SOL/MSTR/BTC: history's down-prints are 2025 ETF-launch sell-the-news events (Solana ETF -31%), a structurally opposite setup to a leveraged retail meme melt-up that bids these first.
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.
