4-bullet brief | narrative

Polymarket puts 21% on Strait of Hormuz traffic returning to normal by December 31, keeping the outcome a long shot.
Houthi seizure of the Red Sea coast and strategic islands, combined with the Saudi East-West pipeline shutdown from drone strikes, deepens the disruption narrative.
The 21% pricing implies the market sees a roughly four-in-five chance that shipping disruption persists through year-end, consistent with escalating rather than de-escalating conflict.
Polymarket resolves via UMA oracle; 'normal' traffic would need to be defined against a pre-conflict baseline, creating resolution ambiguity if partial recovery occurs.
