币界网报道：Polymarket's prediction markets have witnessed a significant surge in open interest (OI) for Iran-related geopolitical contracts, with "US military action on Iran before July" jumping from $249,000 to $6.19 million in two weeks and "Will the US officially declare war on Iran before July?" rising from $0 to $3.04 million. Markets tracking Iran's Supreme Leader Ali Khamenei also saw a 10x OI increase. While NBA championship betting reached $7.5 million before Game 7, Iran-related markets remain a small portion of Polymarket's total $131 million OI. Platform-wide metrics show declining activity—monthly traders and volume are below half their all-time highs, and new market creation has dropped 23%. The shift from political betting to event-driven speculation reflects changing user behavior.
