The probability that the United States will send warships through the Strait of Hormuz by July 31, 2026, rose sharply by 25.0 percentage points over the past 24 hours, climbing from 29.5% to 54.5% on Polymarket. This surge marks a significant shift in market sentiment within a single day.
Whale activity aligned with the price movement, indicating that large traders increased their net exposure to YES contracts as the odds moved higher. This synchronization between whale flow and the price rally suggests that informed participants are reinforcing the growing market conviction about this geopolitical event. The 24-hour trading volume registered at $7K, reflecting moderate liquidity amid the rapid repricing.
This market’s strong move upward signals a reassessment of the likelihood of US naval action in a strategically critical waterway. The combined rise in price and whale backing points to heightened trader confidence rather than a speculative spike unconfirmed by large bets. Such a decisive shift in odds and whale flow often captures evolving information or emerging geopolitical signals that market participants consider material.
Overall, the data reveals a market increasingly pricing in the possibility of US warships transiting the Strait of Hormuz by late July 2026, with whale activity underscoring the seriousness of this repricing.
