The probability of Hormuz traffic returning to normal by May 15 is at 3.6% YES.

## Key Takeaways

– The blocking of over 70 tankers by U.S. forces appears to suggest continued disruption in the Strait of Hormuz. – Pricing suggests participants view the continuation of the U.S.-imposed blockade as supportive of a NO outcome for a Trump announcement by May 31. – Current market behavior is consistent with the expectation that normal traffic levels in the Strait of Hormuz will not resume by May 15.

## Article Body

Recent reports from U.S. Central Command (CENTCOM) indicate that American forces are actively preventing more than 70 tankers from entering or leaving Iranian ports. This action is part of an ongoing naval blockade aimed at exerting economic pressure on Iran amidst the 2026 conflict that began with U.S.-Israel military strikes. The blockade is a component of “Project Freedom,” which involves significant U.S. military resources to ensure the safe passage of non-Iranian commercial vessels through the Strait of Hormuz, a vital global oil transit chokepoint. Iran has responded to these measures with its own military actions against U.S. and allied vessels, highlighting the ongoing hostilities in the region.

## Market Interpretation

The impact of the blockade news on prediction markets appears to be significant, classified as High. The continued interception of tankers by U.S. forces is consistent with a NO outcome for ship transits reaching 20 on any day by May 31. Additionally, the likelihood of Donald Trump announcing the lifting of the blockade by May 31 appears to decrease, as evidenced by the declining YES probabilities in relevant markets.

## What to Watch

Observers should monitor any changes in U.S. and Iranian military strategies, particularly any potential easing of restrictions or escalation of military engagements. Key dates include May 15, the deadline for traffic normalization, and May 31, the deadline for the potential lifting of the blockade. Developments in diplomatic efforts and international reactions may also impact market expectations in the coming weeks.
