US Marines seize Iranian vessel in Strait of Hormuz blockade enforcement

US Marines have taken custody of an Iranian-flagged vessel attempting to breach the US blockade in the Strait of Hormuz, according to a social media post by President Donald Trump. “Strait of Hormuz traffic returns to normal by end of June” sits at 15% YES.

The seizure represents a direct enforcement action that makes normalization of strait traffic by June harder to imagine. With 73 days until the June 30 resolution, traders are reassessing probabilities. The current odds have dropped significantly from previous levels. This follows a series of IRGC gunboat attacks and persistent US naval operations already underway in the 2026 Strait of Hormuz crisis.

The “Strait of Hormuz Traffic Returns to Normal” market has seen zero trading volume in the past 24 hours, a lull likely driven by uncertainty around the latest developments. The lack of liquidity means even small trades could cause notable price swings.

This seizure adds pressure to an already fragile ceasefire in the region. The US blockade continues, and the odds reflect skepticism that any agreement will come soon. At 15¢, a YES share pays $1 if traffic normalizes by the deadline, a 6.67x return. Betting YES here requires a belief in rapid de-escalation and diplomatic breakthroughs within the next 73 days.

Watch for statements from the Pentagon or Iranian Foreign Ministry. Any signals of negotiation or further military action will directly affect where this market trades next.
