Intro
This market tracks whether the United States and Iran will reach a permanent peace deal by the end of 2026. On Polymarket, the probability of a deal being finalized by December 31, 2026 stands at 71.5%. Resolution will be determined by official statements from both governments or credible reporting confirming a lasting agreement to end military hostilities, as sourced from US and Iranian government announcements.

Frequently asked questions
Prediction market odds on Polymarket reflect aggregated trader bets and financial incentives, which often diverge from traditional polling on diplomatic outcomes. Polls typically measure public sentiment or expert opinion snapshots, whereas prediction markets price in real-time information, geopolitical risk, and trader conviction with money at stake. For a complex event like a US-Iran permanent peace deal, markets may move faster than polls when sanctions, negotiations, or leadership changes occur. Comparing the two reveals whether traders are more or less optimistic than surveyed experts or the general public.
On Polymarket, the top outcome "US x Iran permanent peace deal by May 31, 2026?" is priced at implied probability.

The market resolves on Dec 31, 2026. Resolution hinges on whether a permanent peace deal between the US and Iran is officially announced, signed, and recognized as binding by both parties before that deadline. The outcome is binary: either a qualifying agreement exists by the resolution date, or it does not. Traders should monitor official government statements, treaty signings, and international verification to assess whether the criteria have been met. Any ambiguity in deal permanence or official status may affect how the market settles.
Key catalysts include US-Iran direct negotiations, sanctions relief announcements, nuclear deal progress or collapse, regional proxy conflicts, leadership changes in either nation, and UN or international mediator involvement. Positive signals such as prisoner exchanges, diplomatic envoy visits, or framework agreements typically boost odds, while military escalation, new sanctions, or hardline rhetoric can sharply reduce them. Economic pressure, Israeli-Iranian tensions, and domestic political shifts in both countries also influence trader expectations. Markets will react swiftly to any credible news suggesting movement toward or away from a formalized, permanent accord.
