Polymarket Bets Hit $154M as Trump Weighs Iran Deal

Polymarket traders have placed about $154.44 million in bets on whether the United States and Iran will reach a permanent peace deal by dates through 2026. The contract, launched April 8, offers date-specific outcomes that let traders wager on particular deadlines.

Short-term outcomes show heavy, volatile trading. The May 26 contract has roughly $3.9 million staked and is priced near a 56% chance. The May 31 outcome holds about $42.8 million and trades around 62% odds. A June 30 contract shows $12.5 million in volume and a market probability near 70%. The December 31, 2026 outcome commands $3.6 million and is priced around 91%.

The bets follow a fragile ceasefire that began in early April after U.S. and Israeli strikes on Iranian nuclear sites. The truce was first set for two weeks, has been extended, and officials describe the situation as strained. Negotiators face disputes over Iran’s roughly 440 kilograms of highly enriched uranium, control of the Strait of Hormuz, phased sanctions relief, and long-term limits on Iran’s nuclear program.

Indirect talks, mediated largely through Oman, have continued across several rounds. Negotiators are considering a proposed 60-day ceasefire extension as a framework for broader nuclear and security discussions. Tehran seeks gradual easing of a U.S. naval blockade and the unfreezing of overseas assets. Washington is pressing for transfers of uranium to a third country and strict caps on enrichment; Iran has resisted those demands.

On May 23, President Trump described his choice as “solid 50/50” between accepting a proposed framework agreement and resuming escalated military action. He canceled parts of his Memorial Day weekend plans to remain near Washington, met with Vice President J.D. Vance, Defense Secretary Pete Hegseth and Joint Chiefs Chairman Gen. Dan Caine, and reviewed Iran’s latest counterproposal. Secretary of State Marco Rubio has been involved in the process and has emphasized that any agreement must prevent Iran from developing a nuclear weapon and guarantee free passage through the Strait of Hormuz. The president indicated he could decide by May 24 or 25.

Markets reacted to the developments. Bitcoin rose about 1.5%, climbing from a local low near $74,192 to an intraday high of $77,303 on Bitstamp at 4:30 p.m. ET on May 23. Oil markets have tracked the situation because a reopening of the Strait of Hormuz without restrictions would affect global shipments that have faced elevated risk under the blockade and regional tensions.

Polymarket prices have moved as traders interpret presidential uncertainty and the negotiation timetable. Short-term contracts have traded like swing positions, shifting sharply as each deadline approaches and new signals come from negotiators. Longer-dated contracts have hardened toward the view that a formal agreement, if reached, will occur before the end of 2026.

No formal deal had been signed as of May 23. The ceasefire remained in place and the Polymarket contracts were open. If talks collapse and strikes resume, contract prices would be expected to move against resolution; if a framework is accepted, shorter-term outcomes could expire in the money and longer contracts could tighten toward certainty.
