What if Long-duration iron-air storage undercuts lithium for the grid?
Commercial multi-day iron-air batteries take grid-storage share at low cost, easing pressure on lithium and graphite for stationary applications and reshaping demand.
Every number ships with its receipt — the odds, the range, the precedents, and a public grade at Reality Check. The statistical machinery that produces it is proprietary.

Resolution timeline — how this probability is moving
Our model's odds (electric blue) over time vs the market's (Polymarket, amber), from the past toward the 3–10 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. Loading the probability audit trail…
What it would mean
If this plays out, it is a risk-on shock. Commercial multi-day iron-air batteries take grid-storage share at low cost, easing pressure on lithium and graphite for stationary applications and reshaping demand. The trigger decomposes into signed root‑shocks — Clean-energy abundance ▲ · Industrial demand ▼ · Risk appetite ▲ · Scientific breakthrough ▲ — which propagate through our causal graph to the markets below.
