Polymarket’s May 15 ceasefire contract fell sharply to 37% as trading volume surpassed $107 million, while the market’s rules require public confirmation from both governments for a formal ceasefire to resolve yes.
Polymarket’s implied odds for a “U.S.-Iran ceasefire by May 15” dropped to 37%, down 45% over 24 hours, with total trading volume exceeding $107 million. The contract resolves “yes” only if both the U.S. and Iranian governments publicly confirm a formal ceasefire by 11:59 p.m. ET on May 15. This adds a new market-based signal to the broader backdrop of reported discussions involving the United States, Iran and regional mediators over a possible 45-day ceasefire and a two-stage framework for a permanent agreement.
