Iran considers banning Israeli-linked ships from Strait of Hormuz

Iran is mulling a law to ban Israeli-linked ships from the Strait of Hormuz. The Polymarket contract on UK warships transiting the strait by April 30 sits at 8.5% YES.

Market reaction

The warships through the Strait of Hormuz market dropped from 12% to 8.5% over the past 24 hours, consistent with ongoing speculation and no concrete military action. The proposed legislation also affects the Strait of Hormuz traffic returning to normal market, though low trading volume makes it hard to measure a specific odds change. With the possibility of further restrictions, the likelihood of traffic normalizing by June looks lower.

Why it matters

A ban on Israeli-linked ships through Hormuz could prompt the UK to consider a naval response, which would directly resolve this contract. However, the news comes from a tier-3 source and lacks official confirmation or immediate actionable developments. The market remains speculative unless the UK or other nations confirm military maneuvers in response.

What to watch

Official statements from the UK Ministry of Defence or allied navies are the key trigger. Any announcement of ship deployments or heightened military readiness could move odds sharply.

Trade specs

A YES share priced at 8.5¢ pays $1 if the UK sends warships, a 11.8x return. The question is whether the potential for escalation justifies the risk at that price.
