A Polymarket prediction market on a permanent US-Iran peace deal by May 31, 2026, sees 'No' favored at 71.5%, despite recent reports of progress on a framework agreement. The market's strict definition of 'permanent peace' and a tight deadline challenge the 'Yes' outcome.

The high-stakes Polymarket prediction market, asking if the U.S. and Iran will agree to a permanent peace deal by May 31, 2026, is currently trading with a strong lean towards 'No' at 0.715 (71.5% probability), while 'Yes' stands at 0.285 (28.5%). With over $13.8 million in trading volume, this market reflects significant interest in the volatile relationship between Washington and Tehran, particularly as the specified deadline rapidly approaches.

Recent developments, primarily from May 6-7, 2026, indicate a flurry of diplomatic activity. Reports suggest the U.S. and Iran are "closing in on a one-page memo to end their war" and establish a framework for more detailed nuclear negotiations. This proposed 14-point Memorandum of Understanding (MOU) is reportedly being mediated by Pakistan, with the U.S. awaiting Iran's response within 48 hours as of May 6. Iran's Foreign Ministry has confirmed it is reviewing the proposal and will convey its position through Pakistani intermediaries.

The rumored terms of this potential MOU are comprehensive, including the cessation of hostilities, the lifting of blockades on the strategically vital Strait of Hormuz, the removal of U.S. sanctions, the unfreezing of Iranian assets, and an Iranian commitment to a 12-15 year moratorium on uranium enrichment. Additionally, Iran would reportedly transfer its stockpile of highly enriched uranium out of the country and pledge not to operate underground nuclear facilities. Critically, this initial agreement would then "trigger a 30-day negotiation period" for a more detailed, final agreement.

Despite the reported progress, significant hurdles and skepticism remain. An Iranian official reportedly dismissed the proposal as "more of a wishlist than a reality," and a senior Iranian lawmaker echoed this sentiment, calling the Axios report unrealistic. Iran's Foreign Ministry spokesperson emphasized that genuine engagement, not "deception, extortion or coercion," is required for negotiations. U.S. Secretary of State Marco Rubio described the talks as "highly complex and technical," even noting some Iranian leaders are "insane".

President Trump's statements have also introduced an element of uncertainty. While acknowledging "great progress," he also declared "Never a deadline" for negotiations and threatened "much higher level and intensity" bombing if a deal isn't reached. Furthermore, a Channel 12 report indicated a lack of agreement on the destination for Iran's uranium stockpile, with Trump allegedly telling Prime Minister Benjamin Netanyahu that no deal would materialize without resolution on this point.

The market's current odds, heavily favoring 'No,' appear to reflect these complexities and the strict resolution criteria. The Polymarket question requires a "permanent peace deal" that explicitly indicates military hostilities have "ended or will permanently cease" by May 31, 2026. An agreement that merely "triggers a 30-day negotiation period" for such a deal, as the proposed MOU reportedly does, may not meet this high bar within the specified timeframe. Given the ongoing "war" that began on February 28, 2026, and the short window remaining, a definitive, lasting end to hostilities, as opposed to a framework for future talks, seems a difficult outcome to achieve in less than a month.

As the clock ticks towards the May 31 deadline, the market remains skeptical that the current diplomatic push, despite its reported progress on an initial framework, will culminate in a fully realized, permanent peace deal as defined by the market question.
