Polymarket lifts Israel-Iran ceasefire odds to 97.6% through July 18

Polymarket Ceasefire Ladder Reprices After Kuwait Damage Report Tests Israel–Iran Truce Confidence

Polymarket traders are pricing a very high chance that the Israel x Iran ceasefire holds through the earliest rungs of its date-ladder, with the July 18 strike at 97.6% on $232,369 matched. The repricing comes as new regional damage reports add fresh stress-test headlines to a market that has stayed low-volatility overall.

Key Takeaways

Polymarket’s leading rung implies a 97.6% chance the ceasefire continues through July 18 (Yes 97.6% / No 2.4%).
After a brief dip, odds snapped back higher, signaling traders still expect near-term continuity despite the latest Iran-attack damage report.
This is a date-ladder that runs through Aug. 31, with the market set to resolve by 2026-08-31 23:59 UTC.

A report said Kuwait recorded injuries and damage to power and water infrastructure, plus an oil facility, after an Iran attack. The incident adds a new headline risk signal in the region even as markets continue to trade the question of whether the Israel–Iran ceasefire remains in place over specific dates.

Odds Curve & Liquidity Snapshot: July 18 at 97.6% on $232,369 Matched as July 22 Drops to 79.0% and Aug. 31 to 40.5%

This is a Polymarket date-ladder (price_ladder) where each strike is its own binary: “Yes” means the ceasefire is still in effect through that date, while “No” means it fails before or by that cutoff. The near-term rungs show strong consensus: July 18 is Yes 97.6% / No 2.4%, while July 22 is Yes 79.0% / No 21.0%; farther out the curve steepens with July 31 at Yes 61.5% / No 38.5% and Aug. 31 at Yes 40.5% / No 59.5%. The latest move is a +3.75 percentage-point jump (93.85% to 97.6%) on $232,369 matched, following an earlier -2.4pp downtick—price action consistent with the summary signals of low volatility, stable consensus, and moderate bullish momentum. Read that curve as a term-structure view of risk: traders are confident about days ahead, but increasingly unsure as the horizon extends toward the Aug. 31 resolution window.

Watch whether the mid-curve rungs (July 25 at Yes 72.0% / No 28.0% and July 31 at Yes 61.5% / No 38.5%) tighten or widen; the spread between short-dated and month-end strikes is where disagreement about durability is most visible before the Aug. 31 resolve-by timestamp.

What Traders Watch Next on Polymarket: Mid-Curve Tightening (July 25/31) and Cross-Contract Hedges in Macro and Crypto M

Zooming out from the ladder itself, traders often sanity-check their positioning against adjacent Polymarket contracts that capture second-order risk and potential hedges. In the same complex, 98.85% “No” in “Strait of Hormuz traffic returns to normal by July 31?” sits alongside bigger-liquidity sentiment reads like 72.5% “No” in “Will the U.S. invade Iran before 2027?” and 78.0% on “Mojtaba Khamenei” in “Iran leader end of 2026?”. For nearer-dated catalysts, “US x Iran Effective Ceasefire by...? (2 week pause)” is priced at 50.5% for “August 31,” while “Iran announces withdrawal from MOU negotiations by...?” has “August 15” leading at 23.0%—useful cross-checks when the mid-curve starts to tighten or gap out.
