The probability that the United States will send warships through the Strait of Hormuz by July 31, 2026, rose sharply by 17.0 percentage points in the last 24 hours, climbing from 24.0% to 41.0% on Polymarket. This sizable repricing reflects a notable shift in market sentiment regarding US naval operations in this critical maritime chokepoint.
Alongside the price surge, whale trading activity aligned with the upward momentum, reinforcing the shift in odds. Over the same period, Polymarket recorded $8K in volume on this question, indicating moderate market engagement amid the move. The synchrony of whale flow and price action suggests that larger traders are backing the increased likelihood of US warship deployment through the Strait of Hormuz.
This joint price and flow dynamic signals growing market conviction that the US will take naval action in this strategic waterway by the specified deadline. The rapid rise in odds, supported by whale participation, marks a significant update in the market’s assessment of geopolitical developments affecting US military movements in the region.
