A what‑if from the future

What if AI datacenter demand outstrips the power grid's supply?

Datacenter load outrunning supply is the core bull case: power scarcity validates the AI-capex spend, lifting NVDA and the gas complex (TTF/Henry Hub) as gas becomes the swing firm fuel. Rhymes with the 2024 PJM capacity-auction spike that priced data-center demand and lifted IPP/gas names. Skeptical: connection moratoriums also cap near-term GPU deployment, so the unambiguous winners are gas generators and grid copper, not just chips. The +0.9 ai_capex/NG map is sensible.

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. Datacenter electricity demand outstrips new supply in key US regions, forcing connection moratoriums and price spikes. The trigger decomposes into signed root‑shocks — Natural gas ▲ · AI capex ▲ — 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.

Probable recommendation

If the scenario above plays out, the probable cross‑asset positioning → a scenario‑conditional read, not personalized investment advice
Short
For a common-man portfolio: Mixed for a typical portfolio — the move is more about rotation than direction. Favour the winners over the losers below rather than net exposure.

Why we may diverge from history

Trust the cascade long on ASML/AMD: the small negatives are chip-specific noise (Nvidia valuation, TSMC, CHIPS Act) — an AI datacenter power shock confirms the compute-demand thesis driving these names; off-channel analogues.

Historical precedent — what analogous events actually did

Across 14 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

AI datacenter demand outstripping grid supply already happening; moratoriums and spikes near-certain trend. A base‑rate‑anchored prior, continuously scored against what actually happens — not a forecast.
