The odds on Polymarket that shipping traffic through the Strait of Hormuz will return to normal by December tumbled to 55% on Tuesday, a day after Iran's Revolutionary Guards claimed they struck two tankers in the strategic waterway. The Guards also said they targeted U.S. defense systems in Bahrain, a move that ratcheted up tensions in the region.
The Revolutionary Guards' claims
On July 21, Iran's Revolutionary Guards announced they had hit two tankers in the Strait of Hormuz. The same statement said they attacked U.S. military defense systems stationed in Bahrain. The claims were made without providing evidence, and the extent of any damage remains unclear. The Strait of Hormuz is a narrow passage that carries about a fifth of the world's oil supply, making even minor incidents a trigger for global markets.
Betting market reaction
Polymarket, a platform that lets users bet on the outcome of real-world events, saw the probability of 'Strait of Hormuz traffic normal by December' drop from previous levels to 55%. The shift reflects growing uncertainty among traders who follow the platform. The market had initially shown higher confidence in a return to normal operations, but the claims from Iran reversed that trend.
What's at stake
The Strait of Hormuz is a critical chokepoint for crude oil shipments from the Middle East. Any sustained disruption can push up oil prices and threaten global supply chains. The Guards' claims, if true, would mark a significant escalation in a region already on edge. But the lack of independent verification leaves room for doubt. The drop in betting odds signals that market participants are pricing in a higher chance of prolonged tensions.
The next few days will likely bring more clarity on whether the claimed strikes actually occurred. Traders and insurers are watching for any official confirmation from shipping companies or naval forces that patrol the area. Meanwhile, the 55% odds on Polymarket suggest a split view: some still bet on a return to normal by year-end, while others see the situation worsening.
