The market “Will 30 ships transit the Strait of Hormuz on any day by July 31, 2026?” saw its YES contract price collapse by 58.2 percentage points over the past 24 hours, dropping from 95.4% to 37.2% according to Polymarket Breaking data on July 14. This sharp decline contrasts with whale activity, which showed a net inflow of $31K into YES positions during the same period.
Whales traded actively, with $59K in buy volume and $28K in sell volume, spread across 74 unique whale wallets. Despite this significant whale buying interest, the YES price on Polymarket dropped precipitously, creating a notable divergence between price action and large trader flow. The on-chain Polydata mid-price remains much higher at 96.4%, highlighting a stark difference between the Polymarket Breaking feed and on-chain valuation.
Overall 24-hour volume on Polymarket was $44K, contributing to a lifetime market volume of $99K with 174 unique traders involved. The conflicting signals between whale buying and the sharp price drop underscore a complex market dynamic, where whales appear to be accumulating YES contracts despite the broader market sharply repricing the probability lower.
This combination of strong whale buying against a collapsing price suggests uncertainty or disagreement among market participants about the likelihood of 30 ships transiting the Strait of Hormuz by the specified date. It signals a market in flux with competing forces shaping the contract’s outlook.
