The probability of Iran launching military action against a Gulf State on July 13 jumped 32.5 percentage points in the last 24 hours, climbing from 40.0% to 72.5% on Polymarket. This sharp repricing reflects a significant shift in market sentiment around the geopolitical risk of conflict in the Gulf region.
Whale trading activity moved in tandem with the price surge, confirming the upward momentum. Large investors collectively increased their exposure to YES contracts, reinforcing the market’s reassessment. The alignment between whale flow and price indicates that informed participants are backing the higher odds implied by the recent move.
Trading volume over the past day reached $6K, suggesting moderate liquidity behind the price change. The combination of a sizable price increase and supportive whale flow underscores a notable consensus shift rather than a short-lived price spike.
This repricing signals that market participants are increasingly factoring in the likelihood of Iranian military action on the specified date. The concurrent whale buying further validates the elevated probability, highlighting the growing conviction behind this scenario in the prediction market.
