What if a drilling breakthrough makes geothermal scalable nationwide?
Commercially scalable enhanced geothermal adds firm clean baseload — a growth-positive, multi-year supply story; the mapped NVDA/AI-capex and growth-surprise legs capture the optimism but the timeline (3-10y) makes any tape move pure narrative. Closest rhyme is the shale-drilling breakthrough that re-rated US energy supply over years. Skeptical: Fervo-style EGS is promising but capital-intensive and unproven at GW scale, so this is a thematic, not a tradable, catalyst; don't chase chips on a drilling headline.

What it would mean
If this plays out, it is a mixed shock. A drilling breakthrough makes enhanced geothermal commercially scalable, opening firm clean baseload nationwide. The trigger decomposes into signed root‑shocks — AI capex ▲ · Growth surprise ▲ — which propagate through our causal graph to the markets below.
