What if High gas price flips US dispatch back to coal generation?
A Henry Hub spike above $5 flips the power-stack economics so utilities dispatch more coal and less gas, capping gas demand growth while lifting thermal-coal and emissions-allowance prices.
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 mixed shock. A Henry Hub spike above $5 flips the power-stack economics so utilities dispatch more coal and less gas, capping gas demand growth while lifting thermal-coal and emissions-allowance prices. The trigger decomposes into signed root‑shocks — Natural gas ▲ · Inflation surprise ▲ · 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.

| 1 | Natural gas NGon Hyperliquid 📈 chart | Commodity | ▲ +0.5% hist -6.69–+1.81% · other way +12.35% (n=12) |
| 2 | 30y Treasury yield DGS30 📈 chart | Rate | ▲ +1bp hist -2.78–+6.99% · other way +6.3% (n=12) |

Probable recommendation
Historical precedent — what analogous events actually did
Across 39 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.
