This market will resolve to "Yes" if a national government, its military, or a broad consensus of credible reporting confirms that the listed country's warships transited through the Strait of Hormuz by April 30, 2026, 11:59 PM ET. Otherwise, this market will resolve to “No”. 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.In the ongoing 2026 Strait of Hormuz crisis, Iran's IRGC has restricted maritime traffic through attacks on over 20 merchant vessels since early March, mines, and a March 27 closure to U.S., Israeli, and allied ships, while opening a tolled northern passage for select non-aligned merchants like Chinese and Indian carriers. President Trump urged allies including the UK, France, Japan, and others to deploy warships for escorts, prompting joint statements of readiness from six European and Asian nations on March 19 and France's outreach to 35 countries on March 26, yet no confirmed warship transits have occurred amid threats and failed U.S. approaches. India's Operation Urja Suraksha deploys five warships to escort exiting tankers in the Gulf of Oman, nearing but not entering the strait. Trader consensus reflects uncertainty over escalation risks before April 30, with potential multinational missions as key catalysts.
