The repricing follows headlines about overnight U.S. strikes in Iran, and this ladder market shows how timing expectations shift across multiple deadlines.<\/p>\n<h3>Key Takeaways<\/h3>\n<ul>\n<li>Market-implied favorite is \u201cEffective ceasefire by August 31\u201d at 58.5% (No 41.5%).<\/li>\n<li>After reports of overnight U.S. strikes in Iran, the ladder repriced toward a later ceasefire window rather than near-term deadlines.<\/li>\n<li>Contract resolves by 2026-08-31 23:59 UTC; the leading line is up 5.0 points over both 24h and 7d.<\/li>\n<\/ul>\n<p>A report said overnight U.S. strikes hit two provinces in Iran, leaving one person dead and several others wounded. The headline framed the incident as a fresh escalation, which serves as the immediate catalyst traders are mapping into ceasefire timing odds.<\/p>\n<h2>Odds Snapshot: $1.49M Volume Puts \u201cCeasefire by Aug 31\u201d at 58.5% vs Aug 14 at 43.0% and Jul 31 at 31.5%<\/h2>\n<p>This is a price-ladder (deadline ladder) market: each strike is a separate \u201cceasefire by X date?\u201d contract, so the label is a cutoff, not a settlement price or a single yes\/no event. The August 31 line leads at Yes 58.5% \/ No 41.5%, while nearer deadlines trade much lower\u2014August 14 sits at Yes 43.0% \/ No 57.0% and July 31 at Yes 31.5% \/ No 68.5%, with the very near July 18 at Yes 0.3% \/ No 99.7%. The 24-hour and 7-day change are both +5.0 points with \u201cstrong\u201d momentum and \u201cstrengthening\u201d consensus, implying traders are converging on a ceasefire scenario but discounting a fast turnaround within days. At $1.49M in volume, the market is actively updating, and the step-down from 58.5% (Aug 31) to 43.0% (Aug 14) quantifies how much probability traders assign specifically to a two-week pause versus a later de-escalation window. The resolution timestamp (2026-08-31 23:59 UTC) makes the final strike the key settlement boundary, while earlier strikes function as tradable estimates of timing rather than a single binary outcome.<\/p>\n<p>Watch whether odds lift on the earlier rungs (July 24, July 31, August 14) or stay concentrated on August 31; that split is the cleanest read on whether traders are shifting from \u201ceventually\u201d to \u201csoon\u201d ahead of the 2026-08-31 23:59 UTC resolution.<\/p>\n<h2>What Traders Watch Next on Polymarket: Earlier Deadline Rungs (Jul 24\/Jul 31\/Aug 14) vs the Aug 31 Anchor Contract<\/h2>\n<p>Zooming out from the ceasefire timing ladder, traders are also benchmarking the knock-on scenarios that can reprice the whole complex across Polymarket. Big attention is on 97.75% No in \u201cStrait of Hormuz traffic returns to normal by July 31?\u201d ($18,719,328 volume, +39.75pp), 78.5% No in \u201cWill the U.S. invade Iran before 2027?\u201d ($45,375,440, +10.0pp), and 42.0% leading \u201cAugust 31\u201d in \u201cIran full airspace closure by&#8230;?\u201d ($4,803,643, +3.0pp). Taken together, these side contracts act as adjacent gauges for how traders are weighing shipping normalization, escalation risk, and operational constraints alongside the headline ceasefire timeline.<\/p>\n<h2>Odds Trend<\/h2>\n<table>\n<thead>\n<tr>\n<th>Window<\/th>\n<th>Change (pp)<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>24h<\/td>\n<td>+5.0<\/td>\n<\/tr>\n<tr>\n<td>7d<\/td>\n<td>+5.0<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Implied odds (last 48h)2550Odds %August 31August 14July 31July 24<\/p>\n<h2>By the Numbers<\/h2>\n<ul>\n<li><strong>Platform:<\/strong> Polymarket<\/li>\n<li><strong>Market:<\/strong> US x Iran Effective Ceasefire by&#8230;?
