The Polymarket contract “Will 30 ships transit the Strait of Hormuz on any day by July 31, 2026?” saw its YES price drop 58.2 percentage points in the past 24 hours, falling from 95.8% to 37.5%. This dramatic repricing indicates a significant shift in market sentiment about this maritime event.
Despite the sharp decline in the YES price, whale behavior diverged from the price movement. Over the same period, whales net bought $15K into YES contracts, with buy volume at $29K and sell volume at $13K, spread across 56 unique whales.
Market volume over 24 hours was $20K, contributing to a lifetime volume of $61K with 128 unique traders participating. A notable discrepancy exists between the Polymarket Breaking YES price at 37.5% and the Polydata on-chain mid-price of 96.4%, highlighting a significant price divergence across data sources.
The combination of a steep price fall alongside steady whale accumulation signals a contested market narrative. While the broader market has sharply reduced the implied probability of 30 ships transiting the Strait of Hormuz by the stated date, whale activity indicates some large traders maintain substantial conviction in the YES outcome despite the price collapse. This tension between price and flow underscores ongoing uncertainty and potential volatility in this contract’s outlook.
