The probability that 30 ships will transit the Strait of Hormuz on any day by July 31, 2026, collapsed by 50.8 percentage points in the past 24 hours, dropping from 92.8% to 42.0% on Polymarket’s Breaking feed. This dramatic repricing contrasts with whale activity, which saw a net inflow of $36K into YES contracts during the same period, driven by $66K in buys against $30K in sells from 89 unique whales.
Polymarket’s 24-hour volume on this market reached $50K, contributing to a lifetime market volume of $111K across 198 unique traders. Notably, the on-chain Polydata mid-price stands at 96.4%, substantially higher than Polymarket’s current 42.0% YES price, highlighting a significant market-data divergence.
The opposing directions of price and whale flow indicate a disconnect between large traders and the overall market sentiment reflected in the price. While whales are accumulating YES positions, the market price sharply discounts the likelihood of this event. This divergence suggests uncertainty or competing views about the risk of a large-scale transit through the Strait of Hormuz by the mid-2026 deadline.
The combination of a steep price drop with strong whale buying activity signals a complex market dynamic.
