The market on whether Iran successfully targeted shipping on July 17 saw its YES price collapse by 46.6 percentage points over the last 24 hours, dropping from 52.1% to 5.5% according to Polymarket’s Breaking feed on July 20.
This dramatic repricing occurred amid a divergence between whale trading activity and market price movement. Large traders, identified as whales, collectively bought $6K worth of YES contracts while selling $3K, resulting in a net $3K inflow into YES positions across 22 unique whale addresses. This flow contrasts with the sharp decline in the YES contract price, which suggests that while retail or smaller traders pushed the odds down aggressively, whales maintained or increased exposure to the YES outcome.
Overall 24-hour volume on the market totaled $5K, with the lifetime market volume reaching $18K and 126 unique traders participating since inception.
The combined picture of a steep drop in YES price alongside net whale buying indicates a complex dynamic, highlighting tensions between retail sentiment and whale positioning in this politically sensitive market.
