4-bullet brief | narrative

Polymarket prices a 17% chance the United States directly invades Iran before 2027.
Active Iran-Israel exchanges and IRGC energy asset threats are hawkish inputs, yet the market keeps direct US invasion well below one-in-five.
The Iranian regime survival contract at 97% (Story 24 candidate) implies the market sees regime continuity as far more likely than US ground action.
Resolves via Polymarket's uma_oracle based on credible reporting of a US ground or large-scale air invasion of Iranian territory.
