A Polymarket market with over $120 million in trading volume has entered the platform's dispute resolution process, as traders disagree on whether a U.S.-Iran agreement announced on June 15 qualifies as a 'permanent peace deal' under the market's rules. The market asked whether the United States and Iran would agree to a permanent peace deal by June 15, requiring the agreement to explicitly indicate military hostilities have ended or will permanently cease. As of Wednesday morning, the dispute remained under review through UMA's governance token voting system, with more than 99% of voting power supporting a 'Yes' outcome. The disagreement centers on whether a memorandum of understanding announced by the Trump administration meets the market's definition of permanence, particularly after Trump characterized the agreement as an interim measure in post-deadline comments.
Market Resolution Criteria and Voting Status
The market's resolution rules specified that a qualifying agreement must "explicitly indicate that military hostilities between the two countries have ended or will permanently cease," or otherwise clearly signal a "lasting end to hostilities." As of Wednesday morning, more than 99% of voting power in the UMA governance token system had backed a "Yes" outcome, according to the market page. The June 15 contract attracted more than $120 million in volume and is one of the largest political markets currently on Polymarket.

Traders Dispute Whether MoU Meets Permanence Standard
Supporters of a "Yes" resolution pointed to Trump's June 14 Truth Social post and Iran's confirmation as evidence that both governments publicly confirmed a deal had been reached before the market's June 15 deadline. Traders who bought "No" contracts contended the agreement falls short of the market's definition of a permanent peace deal. Critics noted that the agreement includes a 60-day ceasefire and still leaves issues like Iran's nuclear program and sanctions open to negotiations.
Trump Calls Agreement Interim Measure at G7
Trump made comments on Wednesday, after the market's deadline passed, characterizing the agreement as an interim measure rather than a final settlement. "It's a memorandum of understanding," Trump told reporters on the sidelines of the G7 summit in France, according to Reuters. "If I don't like it, we'll go back to shooting at them, dropping bombs on their head."
Polymarket Faces Second Major Dispute This Month
This controversy follows another major Polymarket dispute earlier this month involving a market on whether Strategy would sell any bitcoin before May 31. That contract ultimately resolved to "No" following a UMA vote despite objections from traders who argued that the company did indeed make the sale before the market deadline, even though it wasn't revealed in an SEC filing until after the deadline passed.
