What would move this market

  • Official statements, negotiations and deadlines, military action, sanctions, and votes at the UN or in parliaments.
  • Time. It closes on 1 January 2027 (about 59 days away). On a deadline question, every day that passes without the event usually pulls the Yes price down, unless news makes it more likely.

How it resolves

The rules, word for word as Polymarket publishes them:

This market will resolve to "Yes" if the United States commences a military offensive intended to establish control over any portion of Iran by December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No". For the purposes of this market, land de facto controlled by Iran or the United States as of November 4, 2025 12:00 PM ET, will be considered the sovereign territory of that country. The resolution source for this market will be a consensus of credible sources.
Closes:
1 Jan 2027, 04:59 UTC
How results are settled:
Polymarket markets are typically settled through UMA's optimistic oracle: a result is proposed after the event, can be disputed during a challenge window, and is final once undisputed or decided.

How to read these odds
