## Resolution

**Resolves by:** May 28, 2026

**Source:** the market description on Polymarket; final settlement via UMA optimistic oracle.

### Market description (verbatim from Polymarket)

> This market will resolve to “Yes” if the U.S. officially announces an extension of the ceasefire agreement between the U.S. and Iran, defined as a publicly announced commitment to the continued halt of direct military engagement with Iran or announces a new peace agreement, ceasefire framework, or diplomatic agreement under which the ceasefire will continue by the specified date 11:59 PM ET. Otherwise, this market will resolve to "No".
> 
> If a qualifying announcement is officially made before the resolution date, this market will resolve to “Yes,” regardless of whether the ceasefire extension ultimately takes effect.
> 
> A qualifying announcement requires clear public confirmation from the U.S. government that the U.S. has either:
> 
> 1. Extended its commitment to the ceasefire, either as a dated/time-based extension (e.g. a 60 day extension) or through an explicit statement that the ceasefire has been extended.
> 
> 2. Renewed the existing ceasefire as part of a broader peace agreement, ceasefire framework, or diplomatic agreement under which the ceasefire will continue.
> 
> Statements which merely acknowledge, reaffirm, or describe the current ceasefire as remaining in effect, or which outline further negotiations or de-escalation measures, without announcing a new extension period, or successor agreement under which the ceasefire will continue, will not qualify.
> 
> The following would qualify:
> - President Trump announcing that “the ceasefire has been extended for another 60 days.”
> - An official U.S. statement announcing that “the United States and Iran have agreed to extend the ceasefire framework while negotiations continue.”
> - President Trump’s April 21, 2026 announcement extending the ceasefire “until the Iranian negotiators could reach a unified proposal.”
> - An announcement that the US and Iran have agreed to a new temporary framework under which the ceasefire would continue as Iran gradually reopens the Strait of Hormuz and the United States begins to unfreeze Iranian assets would qualify.
> 
> The following would not qualify:
> - Statements that the ceasefire merely “remains in effect” or “continues to hold,” without announcing a new extension, renewal, or successor agreement.
> - Statements that “the ceasefire will remain in effect while negotiations continue,” without announcing that the ceasefire itself has been extended, or a new framework or deal has been reached
> - Statements that negotiations are progressing, that talks are ongoing, or that the parties are “getting closer” to a deal, without announcing that the ceasefire itself has been extended, renewed, or continued under a new agreement.
> 
> An overwhelming consensus of credible reporting that a qualifying extension or successor agreement has been definitively established will also suffice for a “Yes” resolution.
> 
> This market’s resolution will be based on official statements from the U.S. government and will not require confirmation from Iran.
