What counts as YES?
The source target date is market metadata and may differ from the actual event finish. The rules below determine the outcome.
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, between market creation and the specified date, 11:59 PM ET. Otherwise, this market will resolve to “No”. An announcement 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 is made, this market will resolve to “Yes” regardless of whether it is later reversed, or whether the blockade actually ends in practice. Resolution will be based on 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 US naval blockade remains in force and was just expanded (Task Force Iron Gate); US forces disabled a blockade-running ship on Nov 7. But lifting the blockade is a central Iranian demand in the Qatar-mediated two-day proposal, and Trump says a strong deal would make new strikes unlikely, so any de-escalation deal would probably include a blockade suspension. Raised from my 18% by-Nov-30 forecast to reflect the extra month.
Source 1 ↗ Source 2 ↗Post-election pressure and active Qatari mediation create a meaningful chance of a negotiated suspension within seven weeks. However, Trump's November 9 position was to maintain the blockade while deferring further strikes, so reduced fighting does not imply lifting the blockade. I put YES below 50%, but an unconditional announcement of even a temporary general suspension would qualify, including one subsequently reversed. The main uncertainty is whether negotiations overcome the disagreement about which side moves first.
