The probability of Iran launching military action against a Gulf State on July 16 dropped 30.5 percentage points in the past 24 hours, sliding from 69.5% to 39.0% according to Polymarket Breaking data.
While the YES price tumbled sharply, whale trading flow diverged from this sentiment, indicating net buying into the YES contract. This divergence suggests that large traders are positioning contrary to the prevailing price move. Total volume over the last 24 hours on this market was $9K, reflecting moderate activity amid the volatility.
This market’s sharp price decline signals a significant reassessment of the likelihood of military action, possibly driven by new information or shifts in geopolitical expectations. The whale flow divergence adds complexity, showing that some large traders remain confident in the YES outcome despite the price drop.
The disconnect between price and whale activity highlights the uncertain and contested nature of this event’s probability among market participants.
