The market on whether 30 ships will transit the Strait of Hormuz on any day by July 31, 2026, saw a dramatic shift as the YES price plunged 75.7 percentage points from 95.8% to 20.1% over the past 24 hours. This represents a major repricing on Polymarket, sourced from the Breaking feed dated July 14.
Despite the steep drop in the YES price, whale activity diverged from the price move. Large traders bought $52K worth of YES contracts and sold $24K, resulting in a net $28K inflow into YES positions. This divergence suggests that while the market price sharply discounted the likelihood of 30 ships transiting the Strait of Hormuz, whales maintained or increased their exposure to the YES outcome.
Overall market volume for the past 24 hours was $30K on Polymarket, contributing to a lifetime market volume of $85K with 140 unique traders involved. Notably, the Polydata on-chain mid-price remains at 96.4%, highlighting a significant discrepancy with the Polymarket Breaking price of 20.1%. This gap underscores conflicting signals between on-chain data and the current market pricing.
The contrasting whale flow and price action illustrate a complex market dynamic where large traders are not aligned with the sharp decline in odds. The divergence between price and whale flow signals ongoing uncertainty and active repositioning in this contract.
