The Polymarket prediction market concerning a permanent peace deal between the United States and Iran by May 31, 2026, has resolved to 'No,' a conclusion strongly anticipated by the market's overwhelming odds. With a trading volume exceeding $84 million, the market's final prices of 'Yes': 0.0035 and 'No': 0.9965 accurately reflected the highly improbable nature of such a deal materializing by the specified deadline.

The market's question, whether Iran and the United States would agree to a permanent peace deal by May 31, 2026, hinged on an agreement explicitly indicating a lasting end to military hostilities. Critically, agreements that were explicitly temporary or did not include a definitive commitment to permanently cease military hostilities would not qualify.

Leading up to the May 31st deadline, diplomatic efforts between Washington and Tehran were characterized by tentative steps and significant hurdles, rather than a breakthrough to a lasting peace. As late as May 28-29, 2026, negotiators reportedly reached a tentative agreement for a 60-day memorandum of understanding (MOU) aimed at extending a ceasefire and initiating new talks on Iran's nuclear program. However, this preliminary agreement required final approval from U.S. President Donald Trump, which was not granted by the deadline, and Iran had not yet confirmed its acceptance.

Further complicating matters, on May 31, 2026, President Trump reportedly sent a revised peace framework back to Tehran, introducing "tougher terms." In response, Iran's acting defense minister indicated that Tehran would submit its own amendments, signaling that a definitive agreement was far from imminent. These exchanges highlighted a continuous disagreement over core provisions, particularly concerning Iran's nuclear program and the lifting of U.S. sanctions.

Throughout May 2026, the U.S. continued its "Economic Fury" campaign, imposing additional sanctions on Iranian financial and shipping networks, which further underscored the ongoing economic pressure and lack of normalized relations. Moreover, reports of U.S. military operations in southern Iran and alleged Iranian missile attacks on Kuwait in the preceding days demonstrated that military hostilities, despite temporary ceasefires, had not permanently ceased. The International Atomic Energy Agency (IAEA) also reported on May 31 that Iran had amassed a record amount of military-grade enriched uranium, a critical point of contention that President Trump insisted Iran must abandon.

Expert analysis and the prevailing geopolitical landscape consistently indicated the unlikelihood of a rapid, permanent peace deal. The deep-seated mistrust, Iran's continued nuclear enrichment, and the persistent U.S. sanctions regime created an environment antithetical to the comprehensive agreement outlined in the Polymarket question. The market's strong lean towards 'No' was a clear reflection of these complex realities, accurately forecasting the absence of a permanent peace deal by the May 31, 2026, deadline.
