Polymarket's prediction market on whether "US forces enter Iran by April 30" has moved to 100% and is now marked "In Review" pending settlement. Total volume has reached $193 million, including $101 million tied to the April 30 expiry. Yes shares last traded at 99.6 cents. The order book shows more than $15.9 million in asks stacked from 99.6 to 99.9 cents, signaling the market is treating a US ground entry into Iran as a fait accompli. A separate Polymarket contract on whether "another country" will carry out military action against Iran by April is priced at 27%. The "US forces enter Iran" market is the largest geopolitical prediction contract of 2026 and ranks among the highest-volume single contracts in Polymarket's history. Interest has surged after weeks of escalating US-Israel strikes following the launch of Operation Epic Fury on February 28.
