What if the SEC reclassifies ether as a security?
An SEC reversal reclassifying ETH as a security forcing US staking delistings is an ETH-specific regulatory shock — ETH -7% as the US institutional bid and staking-ETF complex are gutted, MSTR/Coinbase follow on crypto-regulatory beta. The current roots wrongly inject trade_tension, dragging in semis/Alibaba/Nasdaq tariff effects that have no causal link to a securities-law decision. Closer analogue is the 2023 SEC-vs-exchanges enforcement scare; transmission is regulatory, so the cascade should stay inside crypto.
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.

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 6–18 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 mixed shock. The SEC abandons its March 2026 commodity stance, reclassifying ether as a security and forcing US exchanges to delist staking products. The trigger decomposes into signed root‑shocks — Crypto confidence ▼ · 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's SHORT on COIN: an SEC ETH-security reclassification forcing staking delistings hits Coinbase revenue hard, yet history's +1.9% is a thin 6-window sample including stale 2021 data — base rate unreliable.
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
SEC reversing ETH-commodity stance politically improbable under crypto-friendly 2026 regime; structural, low. A base‑rate‑anchored prior, continuously scored against what actually happens — not a forecast.
