On July 13, 2026, Trump announced the United States would reinstate its naval blockade of Iran, targeting Iranian ships and customers.

This market will resolve to “Yes” if the United States government, or an authorized representative of the United States government, publicly and officially announces the end, termination, lifting, or suspension of the United States’ naval blockade on Iranian ships and ships of Iranian customers before the ceasefire between the United States and Iran ends. Otherwise, this market will resolve to “No”.

If neither a qualifying announcement of the end of the blockade nor the end of the ceasefire between the United States and Iran occurs by June 30, 2027, 11:59 PM ET, this market will resolve to "No".

An announcement of the end of the blockade qualifies if it communicates that the United States will generally cease blocking vessel traffic for Iranian ships and customers, including an announcement that the blockade will not take effect at all, even if some restrictions remain (for example, an imposition of fees). An announcement does not qualify if it reflects only a limited or partial change that stops short of a general end or suspension of the blockade, for example, an exemption for a specific vessel, cargo, or port.

A qualifying announcement must be a declarative statement of the United States government’s present termination or suspension of the blockade, previously-unannounced prior termination or suspension of the blockade, or definitive decision to terminate or suspend the blockade.

A qualifying announcement must clearly and unambiguously identify the end or suspension of the blockade. Statements that merely allude to, reference, or describe an end to the blockade, without clearly communicating it, do not qualify. The announcement need not use specific terminology or reference the end of a blockade by name; an announcement of a resumption of prior obligations, the maintenance of a status quo, or a return to a previously agreed baseline qualifies, provided the substantive policy of ending or suspending the blockade is clearly and unambiguously communicated.

A qualifying announcement must be made through official channels, by an individual acting in an official capacity. Statements made incidentally or informally in a context not intended for official communication do not qualify.

The following do not qualify:

Anonymous, unattributed, or leaked statements not confirmed as official; Statements by persons not authorized to speak for the United States government; Third-party speculation, analysis, or predictions that the United States government will announce or implement an end to the blockade; Satirical, fabricated, hacked, or impersonated communications; and Statements that describe a prospective, contingent, probable, or conditional end to the blockade rather than announcing a present and decided position.

Once a qualifying announcement of the end of the blockade is made before the ceasefire between the United States and Iran ends, this market will resolve to “Yes” regardless of whether it is later reversed, or whether the blockade actually ends in practice. If the ceasefire between the United States and Iran ends before a qualifying announcement of the end of the blockade is made, this market will resolve to “No”.

The primary resolution source for whether the blockade has ended will be official information from the United States government, including the President, the Department of Defense, the Department of State, and United States Central Command (CENTCOM), or the official representatives of the United States government.

The ceasefire between the United States and Iran will be considered to have ended if the United States takes a qualifying military action against Iran after market creation.

A qualifying military action refers to an air strike or a surface-to-surface missile strike, initiated by the United States, that directly impacts Iran. An air strike includes bombs, air-to-surface missiles, and air-launched drones. A surface-to-surface missile strike includes one-way attack drones and surface-to-surface missiles such as cruise or ballistic missiles.

The following actions do not constitute a qualifying military action: Munitions destroyed or intercepted before impact; Surface-to-air missile strikes; Small-arms fire; Ground incursions; Cyber operations; Naval gunfire and artillery fire; Howitzers, artillery pieces, mortars, and rocket artillery (e.g. MLRS systems); Minor surface-to-surface strikes, including short range loitering munitions, FPV drones, and ATGM strikes; Any threat, authorization, or announcement of force that has not been executed.

Any munition that is intercepted or destroyed before impact does not constitute a qualifying military action. Debris, fragments, or any wreckage from intercepted munitions that land on Iran do not constitute a military action regardless of any damage incurred.

“Iran” refers to the terrestrial territory of Iran, including its internal waters. Iran’s maritime territory and airspace are not encompassed. Where territorial borders are disputed, all territory claimed by and under the de facto control of Iran as of market creation will qualify.

The occurrence, attribution, and timing of a qualifying military action will be primarily determined based on a consensus of information available from the resolution sources. Where multiple sources conflict regarding the occurrence, attribution, or timing of a relevant military action, this market will remain open until the earlier of: i) the confirmation of the occurrence, attribution, and timing of the action based on a consensus of information available from the resolution sources or ii) 3 full calendar days (Iran Standard Time) from the date of the first credibly reported evidence of the action. If this period would extend past the end date, this market will remain open to allow for 3 full calendar days to pass. At the end of the third calendar day, if conflicting reports remain, the incident will be adjudicated based on the totality of information available from the resolution sources at that time. No single statement, denial, or presentation of evidence will govern where it is contradicted by the totality of information.

The resolution sources for whether the ceasefire has ended will be official information from the governments and militaries of the United States and Iran and a consensus of credible reporting.
