The probability that Iran would take military action against a Gulf State on July 13 dropped sharply by 41.5 percentage points in the past 24 hours, sliding from 57.0% to 15.5% on Polymarket. This dramatic repricing occurred alongside $51K in trading volume but was marked by a notable divergence between price movement and whale flow.
Whale activity did not support the price decline. Instead, large traders moved counter to the market’s sharp drop in the YES contract, signaling a disconnect between the tape and major liquidity providers. This divergence suggests that while retail or smaller traders pushed prices lower, significant capital remained positioned against that trend.
Such a split between price action and whale flow highlights uncertainty or disagreement among the most influential participants about the likelihood of military action by Iran.
Overall, this pattern indicates heightened volatility and conflicting views on Iran’s intentions, with the market pricing in a much lower probability of military action despite large traders not aligning with that drop. Monitoring this divergence will be key to understanding evolving expectations in this geopolitical event market.
