What if a stale Chainlink price feed drains DeFi lending markets?
A stale Chainlink ETH feed letting an attacker borrow against mispriced collateral drains lending markets cross-chain — an oracle-integrity shock that hits ETH (-5%) and DeFi-levered names via bad-debt fear. Echoes prior oracle-manipulation exploits (Mango, bZx) where a price-feed failure, not market direction, caused the loss. Because Chainlink underpins most DeFi pricing, the real exposure is the shared-dependency monoculture: one feed failing socializes bad debt across every protocol that trusts it.
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 mixed shock. A frozen Chainlink ETH feed lets an attacker borrow against mispriced collateral, draining lending markets across multiple chains. The trigger decomposes into signed root‑shocks — Crypto confidence ▼ · Crypto liquidity ▼ — 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: a stale Chainlink feed draining lending markets is bearish for crypto venues, while the +3.3% base rate is FTX-era regime noise (+89% SOL, +60% SBF), off-event.
Historical precedent — what analogous events actually did
Across 34 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
Oracle stale-price exploits do happen on minor feeds; major Chainlink ETH freeze well-guarded, lower odds. A base‑rate‑anchored prior, continuously scored against what actually happens — not a forecast.
