4-bullet brief | narrative

Polymarket prices the US invading Iran before 2027 at 15%, a clear long-shot read despite escalating proxy conflict.
Iraqi militia drone attacks on Saudi infrastructure, traced to Iran-backed groups, represent direct conflict escalation, yet the market prices direct US military action as unlikely.
The 15% Polymarket price alongside the 21% Strait of Hormuz normalization read (CM-EVT-LCPV825X09) paints a consistent picture: markets expect prolonged disruption but not full US-Iran war.
Polymarket resolves via UMA oracle; resolution would require a confirmed US ground, air, or naval invasion of Iranian territory, not proxy conflict or airstrikes on third-party proxies.
