What if a recession forces $500bn in goodwill writedowns across the S&P?
$500B of synchronized goodwill writedowns vaporize GAAP earnings but are non-cash — credit and cash flow matter more than the P&L print, so the durable move is multiple compression in expensive Nasdaq names, not a credit event. Closest analogue is the 2002 post-dotcom impairment wave (AOL Time Warner's $99B), which gutted reported EPS yet equities had largely pre-traded it. Skeptical: writedowns lag price; markets discount them early, so the cascade likely overstates fresh downside.
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 synchronized recession forces $500B in goodwill impairments across the S&P, vaporizing reported earnings overnight. The trigger decomposes into signed root‑shocks — Recession signal ▲ · 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 short on COIN/AMD/SMH: up-analogues cluster in the 2025 BTC bull and gold/silver squeeze, regime artifacts that won't repeat under a $500B synchronized goodwill-impairment recession.
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
$500B synchronized goodwill wave needs a recession; no broad downturn underway mid-2026; modest. A base‑rate‑anchored prior, continuously scored against what actually happens — not a forecast.
