In short
The market treats this as all but settled, pricing near certainty that Washington will announce some form of halt before the deadline. That reading rests on a single trading day of data at an extreme level, so it reflects strong conviction rather than a long track record. A resumption of strikes, or an announcement judged too partial to count as a general halt, is what would move it.
How the contract works
A contract on this question settles at $1 if the United States officially announces a halt, suspension, ceasefire or termination of offensive military action against Iran before the 11:59 PM ET deadline on 15 August 2026, and at $0 if no such announcement is made in time. The price at any moment reflects what buyers and sellers currently think the chance of that announcement is โ a contract priced at 0.30, for example, would imply the market sees roughly a three-in-ten chance, not this market's actual level. Positions can generally be sold before the settlement date at whatever price the market is showing at that time, rather than held to the deadline.

How the price has moved
The market opened on 29 July 2026 already at 100%, and has stayed exactly there through 13 recorded observations and no movement in the past 24 hours. There is no visible trend to describe because there has been no deviation from the opening level โ this is a market that arrived at near-certainty from its first trade rather than converging on it gradually. The short history means this reflects a strong initial read by early participants rather than a view tested over time or through news shocks.
Context
This market asks whether the United States government will publicly and officially declare an end, suspension or ceasefire in offensive military operations against Iran before 15 August 2026, 11:59 PM ET. The question does not require Iran to agree to anything; a unilateral US announcement of a halt is enough, provided it is a general cessation and not a narrow, partial change. Determination rests on official statements from the US government or its authorized representatives, as reported by major news outlets.
The contract sits at the tail end of a period of US offensive action against Iran severe enough to prompt a dedicated settlement market. The rules explicitly carve out that defensive measures, sanctions, or a naval blockade can remain in place after a YES resolution โ the question is narrowly about offensive operations, not about the broader confrontation ending.
Because the market only began trading on 29 July 2026, the price history is short. What exists points in one direction, but the amount of time the market has had to test that view is limited.
Analysis
The headline figure here is stark: every recorded observation since the market opened on 29 July 2026 has shown 100% consensus, with a range of exactly 100% to 100% and zero movement in the most recent 24 hours. Across 13 price observations on the only venue tracking this question, Polymarket, the price has not deviated. That is a market signalling near-total conviction that a qualifying halt will be announced before 15 August 2026, not a coin-flip or a contested call.
The caveat is that this conviction has only been tested for about a day. A price that has never moved because it has never had time to move is different from a price that has stayed flat under sustained trading pressure over weeks. With $336,073 in total volume concentrated on a single venue, there is real capital behind the current level, but there is no second venue to check it against, and no multi-day trend to show how the market has digested new information.
The settlement language itself matters for where this sits. The rules count a ceasefire, a truce, or even a time-limited cessation as qualifying, and explicitly say defensive measures, sanctions or a naval blockade can continue without affecting the outcome. That is a fairly low bar for YES โ it does not require a permanent peace, an Iranian concession, or a full stand-down of the US military posture in the region. It only requires one clear, official statement describing offensive operations as halted, suspended or ended. A market pricing near certainty is consistent with traders believing that bar is easy to clear given whatever diplomatic or military developments precede 15 August.
What could still move the price is narrower than it looks. The rules specify that a limited or partial change โ something short of a general halt โ does not qualify. If a future announcement is worded ambiguously, or applies only to certain targets or time windows, it could be argued not to meet the bar, which is the kind of dispute that produces price volatility even in a market that currently shows none.
What moves the probability
Deadline pressure to 15 August
The market only has until 11:59 PM ET on 15 August 2026 for a qualifying announcement to occur. Every day that passes without one narrows the window, which would normally push probability down, but the current pricing suggests traders expect the announcement well before the deadline rather than at the last moment.
Low bar in the settlement language
The rules count a ceasefire, truce, or time-limited cessation as sufficient, and allow defensive measures, sanctions and a naval blockade to continue unaffected. This wide definition of what counts as a halt makes YES easier to satisfy than a stricter standard would, and likely explains part of the market's confidence.
Risk of a partial or ambiguous statement
The rules exclude a limited or partial change that stops short of a general halt. If any future US statement is worded narrowly or covers only some operations, disputes over whether it qualifies could reintroduce uncertainty that the current flat price does not reflect.
Single-venue, short-history pricing
With only Polymarket listing this question and just one day of trading behind the current level, the 100% reading has not been stress-tested by competing venues or by news events occurring after the market opened. A shock โ renewed strikes, for instance โ would be the first real test of that conviction.
The case for
- A US official or authorized representative issues a public statement describing offensive military operations against Iran as ended, suspended, or subject to a ceasefire or truce before 15 August 2026.
- The statement covers offensive operations generally rather than a single strike or narrow category of targets, satisfying the settlement rule against partial changes.
- Iranian agreement is not required, so a unilateral US announcement is sufficient on its own to trigger YES.
- Continuing sanctions, a naval blockade, or defensive measures after the announcement do not prevent the market from resolving YES, since the rules exclude those from the definition of offensive action.
The case against
- No official US statement describing a general halt, suspension, ceasefire or termination is made before the 11:59 PM ET deadline on 15 August 2026.
- Offensive operations continue or resume in a way that makes any halt announcement premature or reversed before the deadline.
- A US statement is issued but is judged limited or partial โ covering only certain operations or a short time window โ and does not meet the settlement bar for a general halt.
- Ambiguity in how major news outlets report any statement delays or complicates a clear determination before the deadline.

Resolution rules
This resolves YES if the United States government, or someone authorized to speak for it, publicly and officially states before 11:59 PM ET on 15 August 2026 that offensive US military action against Iran has ended, been terminated, ceased, or been suspended โ including a ceasefire, truce, or time-limited halt. Iranian agreement is not needed, and continuing sanctions, a naval blockade, or purely defensive measures do not prevent YES. A statement that only partially or narrowly reduces operations, without amounting to a general halt, does not qualify, and the market resolves NO if no such statement is made before the deadline.
Calculation methodology โLocal context
A US military campaign against Iran and any move to halt it is a top-tier US national security story, with direct implications for oil markets, shipping through the Strait of Hormuz, and the posture of US forces and allies across the Middle East. For readers in the UK, Canada and Australia, the story also touches allied military and diplomatic coordination with Washington, since these governments are frequently drawn into consultations or public statements when US operations against Iran escalate or de-escalate. For a broader financial audience, the announcement of a halt or its absence is the kind of geopolitical event that has historically moved oil prices and, through them, inflation expectations and interest-rate discussions well beyond the region.
What to watch
The single fixed point is 11:59 PM ET on 15 August 2026, the deadline for a qualifying announcement. Between now and then, watch for official statements from the White House, State Department, Pentagon or other authorized US government representatives specifically describing a halt, suspension, ceasefire or termination of offensive operations against Iran, as opposed to statements about sanctions, defensive posture, or diplomatic talks that do not address offensive military action directly. Any resumption of strikes after an initial halt announcement, or wording that appears to cover only part of the campaign, would be the kind of development that could reopen the question despite the current pricing.
Common questions
- What exactly needs to happen for this to resolve YES?
- An official statement from the US government or an authorized representative, reported by major news outlets, publicly announcing the end, termination, cessation or suspension of US offensive military action against Iran before 11:59 PM ET on 15 August 2026. A ceasefire, truce, or time-limited cessation all qualify.
- Does Iran have to agree for this to resolve YES?
- No. The rules state explicitly that Iranian commitment is not required. A unilateral US announcement of a halt is sufficient on its own.
- What does a market price of 100% actually mean here?
- It means that, based on current trading, participants are pricing the outcome as almost certain to occur. It is not a guarantee โ prices can and do move if new information emerges before settlement.
- What if the US keeps sanctions or a naval blockade in place?
- That does not prevent a YES resolution. The settlement rules specifically say defensive measures, sanctions, or a naval blockade remaining in place do not affect the outcome, since the question is about offensive operations only.
- What counts as a partial change that would not qualify?
- The rules exclude a limited or partial change that stops short of a general halt. A statement addressing only some targets or a narrow window of operations, rather than offensive action as a whole, would likely not meet the bar.
- Why is there only one venue listed for this market?
- Polymarket is currently the only tracked venue trading this specific question. That means there is no cross-venue price comparison available, and the reported consensus reflects a single market rather than an average across platforms.
