The market asking whether 30 ships will transit the Strait of Hormuz on any day by July 31, 2026, saw its YES price collapse by 46.2 percentage points over the past 24 hours, falling from 92.7% to 46.5% on Polymarket.
Surprisingly, this sharp drop in implied probability occurred while whales collectively bought $66K worth of YES contracts and sold $30K, leaving a net $36K inflow into YES positions. This divergence between price direction and whale flow marks a notable dislocation, as the PRICE moved sharply down but large traders increased their exposure to YES.
Polymarket’s 24-hour volume in this market totaled $50K, contributing to a lifetime volume of $111K with 200 unique traders participating to date. The number of unique whales active in the last day was 91, indicating broad whale engagement despite the conflicting signals from price and flow.
Adding to the complexity, Polydata’s on-chain mid-price for YES stands at 96.4%, far above the Polymarket price of 46.5%, suggesting either a market inefficiency or a divergence between on-chain liquidity and the order book.
This combination of a dramatic price drop alongside sizeable whale buying activity signals unsettled market sentiment and potential disagreement among large traders about the likelihood of 30 ships transiting the Strait of Hormuz by the deadline. The disconnect between price and whale flow highlights a market in flux rather than consensus formation.
