The YES price on the Polymarket contract “Will 40 ships transit the Strait of Hormuz on any day by July 31, 2026?” fell sharply by 27.5 percentage points over 24 hours, declining from 63.5% to 36.0% as of the July 12 snapshot. This dramatic repricing signals a significant shift in market expectations about the likelihood of this maritime event.
Despite the steep drop in the YES price, whale trading activity diverged from the price movement. Whale flow did not align with the falling odds, indicating large traders were not pushing the contract lower in tandem with the tape. The 24-hour volume for this market reached $14K, reflecting moderate trading interest amid the volatility.
The divergence between whale flow and price suggests that while the broader market sharply reduced the perceived probability of 40 ships transiting the Strait of Hormuz by the specified date, major traders either maintained exposure or took positions counter to this price movement. Such a disconnect can highlight uncertainty or differing interpretations of geopolitical or shipping developments affecting the Strait.
This combined pattern of a large price drop accompanied by opposing whale flow points to a contested market narrative. It underscores that despite the market’s rapid repricing, influential participants remain engaged with the contract in a way that complicates a straightforward consensus on the event’s probability.
