Iran Political-Stress Headline Nudges Polymarket “Efficient Ceasefire by Aug 31” Odds Decrease

Key Takeaways

• High-priced strike is “Efficient ceasefire by August 31” at 48.5% Sure vs 51.5% No.
• After the catalyst, the main strike drifted down 1.0 pp (49.5% to 48.5%), in step with a weakening near-term ceasefire timeline.
• This ladder resolves on Aug 31, 2026 (23:59 UTC), with separate outcomes for every date-strike somewhat than one single settlement worth.

Ladder Pricing Breakdown: $1.10M Quantity, Aug 31 at 48.5% Sure vs 51.5% No, Entrance-Date Strikes Keep Deep “No”

This can be a price-ladder: every date is its personal binary, so “August 31” at 48.5% Sure / 51.5% No doesn’t settle the market by itself—it’s one strike on the timeline, alongside earlier dates like August 14 at 29.5% Sure / 70.5% No and July 31 at 15.5% Sure / 84.5% No (with July 18 close to zero at 0.4% Sure / 99.6% No). The curve implies merchants see a significant likelihood of an efficient ceasefire by late August, however they assign a lot decrease odds to it arriving in July, reflecting a steep drop-off in near-term timing. Positioning seems softer versus the current common: the most recent quoted degree is beneath the last-5 common (49.5% vs 54.3%), and the historic abstract flags bearish, average momentum with a reversal detected—in step with a market that not too long ago tried increased ranges earlier than fading. Over the past 24 hours and seven days, the contract is down 4.0 pp, suggesting consensus is weakening somewhat than converging, even with over $1.09M traded.

Watch whether or not the ladder steepens or flattens: if August 14 and July 31 stay closely “No” whereas August 31 holds close to 50/50, merchants are expressing timing skepticism somewhat than a blanket rejection of an eventual pause; any follow-through would present up first as sustained strikes within the front-date strikes.
