The probability that Iran successfully targeted shipping on July 13 plunged 25.4 percentage points over the past 24 hours, dropping from an estimated 49.5% to 24.1% on Polymarket. This sharp decline contrasts with whale activity that moved in the opposite direction, with 63 unique whales contributing a net $15K inflow into YES contracts during the same period.
Whale buy volume totaled $24K, exceeding $9K in sells, signaling substantial accumulation despite the falling price. Total market volume over 24 hours was $19K, nearly matching lifetime volume of $42K, highlighting a recent surge in trading interest. The divergence between whale flow and the price move stands out, indicating that large traders are betting against the downward momentum reflected in the market odds.
This split between price action and whale behavior suggests uncertainty or differing interpretations among market participants about the likelihood of a successful Iranian attack on shipping. While prices reflect growing skepticism, whale buying hints at potential confidence in the event’s occurrence. The combined data points to a contested market narrative rather than consensus, emphasizing the complexity of assessing geopolitical risk through prediction markets.
