What if a shared sequencer fails and freezes several rollups at once?
A shared sequencer serving multiple rollups failing simultaneously freezes several L2 ecosystems and their bridged liquidity at once, so the correlated outage hits every dependent L2 token and drags ETH on beta. Rhymes with single-chain sequencer outages (Arbitrum/zkSync 2023-24), but the shared-sequencer twist turns an isolated halt into correlated systemic risk. Forward angle: shared sequencing is sold as an interop upgrade, yet it concentrates a single point of failure — the repricing should penalize the 'based/shared sequencing' thesis specifically, not just the chains that froze.
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 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 risk-off shock. A shared sequencer serving multiple rollups fails, simultaneously freezing several L2 ecosystems and their bridged liquidity. 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 TSM/AMD/SMH: a shared-sequencer failure is only second-order for semis, and the +3% history is stale 2013 Mt. Gox and 2022 FTX windows — pure regime contamination.
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
Shared sequencers still nascent in 2026; single-point failure plausible but adoption-limited blast radius. A base‑rate‑anchored prior, continuously scored against what actually happens — not a forecast.
