A what‑if from the future

What if soaring costs to maintain France's ageing nuclear fleet drag on growth and public finances?

Soaring costs to maintain and rebuild France's ageing nuclear fleet, amid corrosion outages and EPR overruns, weigh on EDF and public finances and act as a persistent drag on French growth.

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 risk-off shock. Soaring costs to maintain and rebuild France's ageing nuclear fleet, amid corrosion outages and EPR overruns, weigh on EDF and public finances and act as a persistent drag on French growth. The trigger decomposes into signed root‑shocks — European energy ▲ · Industrial demand ▼ · Real yields ▲ · Recession signal ▲ — 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.

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.
