This market will resolve to “Yes” if there is an official extension of the two-week ceasefire agreement between the United States and Iran announced on April 7, 2026, defined as a publicly announced and mutually agreed extension to the halt in direct military engagement between the United States and Iran, by the specified date, 11:59 PM ET. Otherwise, this market will resolve to "No". Both extensions of the April 7 ceasefire and new agreements scheduled to take effect before or at the initial agreement's scheduled end will be considered extensions of the ceasefire agreement, provided there is no period during which no ceasefire is in effect. If a qualifying agreement is officially reached before the resolution date, this market will resolve to “Yes,” regardless of whether the ceasefire extension ultimately takes effect. An extension of the ceasefire agreement requires clear public confirmation from both the United States government and the government of Iran that they have agreed to halt military hostilities against one another for longer than the initially agreed two-week period, or for an official extension of the ceasefire agreement in place to be otherwise confirmed by an overwhelming consensus of media reporting. Any form of informal understanding, backchannel communication, de-escalation, or unilateral pause in hostilities without a confirmed agreement on a qualifying extension will not qualify. Similarly, newly agreed-upon humanitarian pauses, limited operational pauses, or temporary tactical stand-downs will not qualify. A newly agreed-upon broader peace deal will qualify if it includes a qualifying extension of the ceasefire agreement/halt in military hostilities. Agreements that outline future negotiations or de-escalation measures, but do not explicitly commit to extending the ceasefire, will not qualify. This market’s resolution will be based on official statements from the United States government and the government of Iran. However, an overwhelming consensus of credible media reporting confirming that an official ceasefire extension agreement has been reached will suffice.Mediators announced on April 15 that the United States and Iran have agreed in principle to extend their fragile two-week ceasefire—effective since April 8 and set to expire around April 22—allowing more time for negotiations on issues like the Strait of Hormuz reopening and sanctions relief. The truce, mediated by Pakistan, followed U.S. and Israeli airstrikes on Iranian military sites starting in late February, with both sides halting hostilities amid stalled Islamabad talks on April 12. Pentagon briefings confirm U.S. strikes remain suspended, though Iran has warned of retaliation without extension. Traders weigh diplomatic momentum against trust deficits and potential escalation, with upcoming talks critical before expiry.
