Amid Iran's March 31 parliamentary approval of a toll regime for Strait of Hormuz transits—explicitly banning US and Israeli vessels while permitting select commercial passages after coordination—traders price the United States at 24% implied probability for warships transiting by April 30, buoyed by its Fifth Fleet presence in Bahrain and historical escort patterns despite President Trump's recent disavowals of direct involvement. France (9%) and United Kingdom (8%) follow, reflecting joint statements and a UK-France multinational naval effort in discussion, alongside France-Japan maritime security talks. India's deployment of warships near the strait to escort commercial vessels like the Pine Gas has fueled speculation, though no confirmed warship transits have materialized since early March restrictions began. Upcoming diplomatic announcements could catalyze shifts.

A "warship transit" is defined as a military vessel passing through the Strait of Hormuz. Military cargo or support vessels will be considered “warships”; however, commercial or civilian vessels will not qualify.
For the purposes of this market, only transits through the Strait of Hormuz will be considered, defined as passage through the narrowest portion of the waterway between Iran and Oman. Operations solely in the Persian Gulf, Gulf of Oman, or Arabian Sea without passage through this narrowest section will not qualify.
Official confirmation by a national government or its military that its vessels transited through the Strait of Hormuz during the specified timeframe will resolve this market immediately. An overwhelming consensus of credible reporting confirming that such a transit occurred during the specified timeframe will also suffice.
Qualifying confirmations include statements such as official announcements that a country has deployed naval vessels to transit or escort shipping through the Strait of Hormuz.
Confirmations referring only to naval presence in the broader region, including the Persian Gulf, Gulf of Oman, or Arabian Sea, without confirmed transit through the Strait itself, as well as aerial operations, cyber operations, or actions by proxies or third parties, will not alone qualify.
The primary resolution source for this market will be official information by the respective national governments or their militaries; however, an overwhelming consensus of credible reporting will also suffice.
