What if regulators crack down on MEV sandwiching of retail traders?
Regulators targeting predatory MEV sandwiching force chains toward encrypted mempools, a modest confidence/compliance overhang rather than a solvency event — ETH dips slightly as builder/searcher economics get reworked. No clean historical analogue; closest is the gradual MEV-Boost/PBS shift that repriced validator-MEV expectations without a market shock. The trade_tension roots drag in tariff/semis/Alibaba, which don't belong; this is a small domestic market-structure tweak, so the cascade should stay crypto-internal and shallow.
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 mixed shock. Regulators target predatory MEV sandwiching of retail traders, forcing chains to adopt encrypted mempools under legal pressure. The trigger decomposes into signed root‑shocks — Crypto confidence ▼ · 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 SHORT on COIN: the +89% Solana and +60% SBF-conviction analogues are 2022-23 BTC-bull regime spikes; an MEV-sandwiching crackdown is COIN-negative, swamped here by BTC-beta.
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
Mandatory encrypted-mempool regulation is slow, novel; MEV concern real but enforcement-driven mandate unlikely soon. A base‑rate‑anchored prior, continuously scored against what actually happens — not a forecast.
