Iran Peace Deal Odds on Polymarket

The complex geopolitical landscape between the United States and Iran is being dissected on prediction markets, with a notable focus on the prospects of a permanent peace deal. According to Polymarket — All Markets, the market betting on a US x Iran permanent peace deal by May 31, 2026, currently sees a 13.5% probability, attracting $11.2 million in volume.

This specific prediction market, which closes at the end of 2026, suggests a degree of cautious optimism or perhaps a gamble on de-escalation. The definition of a peace deal is crucial: it must explicitly signal a lasting end to military hostilities.

Beyond the peace deal prediction, other related markets on the platform highlight ongoing tensions and potential flashpoints. A market asking whether Iran will close its airspace by May 31, 2026, has seen substantial trading, indicating sensitivity to regional stability.

Furthermore, a separate market gauges the likelihood of a US invasion of Iran before 2027, with current odds favoring 'No' at 70.5%. These diverse markets underscore the utility of prediction platforms in gauging public and speculative sentiment on critical international relations.

The platform also features markets on less direct geopolitical indicators, such as the probability of a US anti-cartel operation occurring outside US soil, and more speculative events like Elon Musk's tweet volume. The diversity of these Polymarket events reflects a broad range of interests among market participants.
