Prediction markets are showing differing contract-based expectations for U.S.-Iran diplomacy. Kalshi, a U.S.-regulated prediction market, indicates rising odds that the United States and Iran could reach a nuclear deal by 2027, though the source does not provide exact percentages or the reason for the move. Separately, Polymarket listed a market on whether the United States and Iran can reach a permanent peace agreement before Donald Trump visits China, with 7% odds at the time described. According to Polymarket’s resolution terms, that contract resolves to No if no qualifying agreement is reached or if no China visit occurs by 11:59 p.m. Eastern Time on Dec. 31, 2026. These prices reflect trader positioning under different contract definitions rather than confirmed diplomatic outcomes.
