What if a perovskite breakthrough halves the cost of solar?
A half-cost perovskite-tandem cell is disinflationary for power capex but a multi-year diffusion story; the only mapped leg, Freeport/copper softer on weaker module-metal demand, is second-order and small. No clean historical analogue; closest is any disruptive cost-down (LED, silicon learning curve) that crushed incumbent margins over years, not days. Skeptical: perovskite durability at scale is unproven, so 'overnight' is hype — treat as a slow grind, not a tradable gap.
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 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 mixed shock. A durable perovskite-tandem cell hits mass production at half silicon's cost, collapsing solar economics overnight. The trigger decomposes into signed root‑shocks — Industrial demand ▼ — 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.

| 2 | Copper XCUon Hyperliquid 📈 chart | Commodity | ▼ -0.2% hist -2.09–+3.84% · other way -1.02% (n=12) |
Probable recommendation
Historical precedent — what analogous events actually did
Across 12 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
Durable perovskite at half-silicon cost overnight is a rare tech breakthrough; commercialization slow. A base‑rate‑anchored prior, continuously scored against what actually happens — not a forecast.
