How the contract works
A contract on this question settles at $1 if the ceasefire is still holding and at nothing if it is not, based on whether Israel or Iran carries out a qualifying strike against the other before the cutoff. The rules set a fairly high bar for what counts: an air strike or surface-to-surface missile strike that directly impacts the other country's territory. Intercepted munitions, small-arms fire, ground incursions, cyber operations, naval gunfire, artillery, and minor or short-range surface-to-surface strikes are explicitly excluded, so a good deal of low-level friction can continue without affecting this contract. The window closes at 11:59 PM Iran Standard Time on 27 October 2026, and the market itself settles the following day, 28 October 2026. A position in this contract can be sold at whatever price the market is offering at any point before settlement, rather than held to the end.

How the price has moved
The available data shows a single venue, Polymarket, pricing this contract at 98% on volume of $289,763, with no cross-venue spread to compare and no reported day-over-day or week-over-week move. A price sitting this close to the ceiling, without a documented recent shift, points to a market that has not encountered new information serious enough to reopen the question since the ceasefire took hold. That stability is itself the story: it reflects an assessment that the specific, narrow bar for a No resolution โ a direct strike on the other's territory โ has not come close to being met.
Analysis
Context
Israel and Iran fought a direct, sustained exchange of strikes in June 2025, a confrontation that ended with a ceasefire brokered with US involvement. Since then, periodic markets like this one have tracked whether that truce survives, day by day, because both sides have continued smaller-scale friction โ interceptions, proxy activity, rhetoric โ without a resumption of direct strikes on each other's territory. This specific contract asks only about the narrow window ending 27 October 2026: has anything happened by then serious enough to count as a real resumption of the war.
The actors are the Israeli military and government on one side and Iran's military and government on the other, with the United States as the outside guarantor whose diplomatic and military posture shapes whether either side calculates that renewed strikes are worth the cost. Nothing in the public record points to an imminent breakdown as of late October 2026, which is the backdrop against which this market is priced.
The consensus across the one venue tracking this question, Polymarket, sits at 98%, on volume of $289,763. That is a high reading, and it is consistent with a market that sees the threshold for a No outcome as narrow rather than the ceasefire itself as fragile. The settlement rules carve out most of the forms of friction that have continued to occur in the region โ interceptions, artillery exchanges, cyber activity, short-range fire โ meaning the contract is not really asking whether tension exists, only whether either government has escalated to a direct strike on the other's territory serious enough to count as renewed war.
Because only one venue currently trades this market, there is no cross-venue spread to read for disagreement, and the figures given do not include a day-over-day or week-over-week move to point to. What can be said plainly is that a price this close to the ceiling, on real but modest volume for a geopolitical contract, indicates a market that has not found new information since the ceasefire took hold that would reopen the question. That is itself informative: in a market built for speed, a flat high price over time is as much a signal as a sharp move would be.
The structural reason the price sits where it does is the asymmetry of the decision facing both governments. Iran would need to calculate that a direct strike on Israeli territory is worth the near-certain Israeli and likely US response, at a moment when its position has been materially weakened by the June 2025 exchange. Israel, for its part, has less incentive to strike first while the ceasefire removes the political and military cost of standing down. Both calculations favor continuation, not escalation, which is the core reason the market prices this close to certain rather than merely likely.
What moves the probability
Narrow definition of a qualifying strike
The settlement rules exclude intercepted munitions, small-arms fire, ground incursions, cyber operations, naval gunfire, artillery, and minor short-range strikes. That means a meaningful amount of ongoing friction between the two countries does not, by itself, move this contract toward No, which pushes the price up.
US diplomatic and military posture
Washington's continued role as guarantor of the ceasefire raises the cost to either side of a unilateral strike, since it invites a US response alongside Israel's or Iran's own retaliation. That dynamic restrains both governments and supports a high price for continuation.
Short resolution window
The contract only needs the ceasefire to hold through 11:59 PM Iran Standard Time on 27 October 2026, a single additional day beyond today. A short window narrows the opportunity for a new qualifying event to occur before settlement, which mechanically supports a high price.
Absence of a reported trigger
No confirmed direct strike on either country's territory has been reported in the run-up to this date. Without a specific precipitating event, there is no concrete reason for the market to move away from its current near-ceiling level.
The case for
- No Israeli or Iranian air strike or surface-to-surface missile strike directly hits the other country's territory before 11:59 PM Iran Standard Time on 27 October 2026.
- Both governments continue to treat the costs of renewed direct conflict, including the risk of US involvement, as outweighing any gains from a first strike.
- Lower-level friction such as interceptions, artillery fire, or cyber activity continues without crossing into the qualifying categories defined in the settlement rules.
- The current diplomatic arrangement, including any US guarantees, remains intact through the settlement date.
The case against
- Either Israel or Iran launches an air strike or surface-to-surface missile strike that directly impacts the other's territory before the cutoff, triggering a No resolution regardless of scale.
- A proxy incident, such as an attack attributed to an allied militia or state actor, escalates into a direct state-on-state strike that both sides decide crosses the line into open conflict.
- A breakdown in US-brokered diplomatic assurances removes the main deterrent currently restraining both governments from a first strike.
- An ambiguous incident, such as a strike near the border of what counts as a direct hit, is reported in a way that both Israeli and Iranian authorities treat as the other side crossing the line.
What to watch
The contract settles on 28 October 2026 based on whether a qualifying strike occurred by 11:59 PM Iran Standard Time the day before. Between now and then, the relevant triggers are any new reports from Israeli or Iranian military or government statements describing a direct air or missile strike on the other's territory, as distinct from interceptions, artillery, or proxy activity, which do not count. Any statement from Washington signalling a shift in its role as guarantor of the truce would also be worth watching, given how central that backing is to both sides' current restraint.
