This summary shows the opening of the venue's official rules. ProbCast has not yet generated an independent plain-English interpretation for this contract — review the full rules before relying on it.
This market will resolve to "Yes" if there is a widely reported coup attempt in Iran at any point between market creation and December 31, 2027, 11:59 PM ET. Otherwise, this market will resolve to "No." A coup attempt is defined as a coordinated and deliberate effort by military, security forces, or other state actors (or factions thereof) to overthrow or unlawfully seize control of the Iranian government or its leadership. Revolutionary actions by non-state forces, isolated protests, or general unrest will not alone qualify. Claims by the Iranian government that a coup attempt was foiled—such as through arrests or disruption of a planned operation—will only count toward a "Yes" resolution if credible independent sources widely report and explicitly characterize the event as a coup attempt. Foiled plots or arrests that occur without any attempted execution of the coup will not qualify. The resolution source will be a consensus of credible reporting.
The contract must resolve based on what has happened by this date.

Research signals — these models are still accumulating the history needed for full validation, and they can disagree with the headline read. Model confidence: low · expected error ±15 pts.
Thin book and/or wide spread. Small orders can move this price disproportionately, so any single print is noisy and easily overread.
Read with caution —Read the latest price with caution; conditions make it an unreliable summary right now.
Short-term motion of the price line (~1h), distinct from the environment above — not a prediction of the final outcome.
Secondary read: leaning toward Trading normally.
A read-only classification of the market environment — how much weight the current price deserves as a read of consensus. It describes conditions, never a trade.
