Odds & Liquidity Breakdown: July 13 Drops to 66.5% on $519,984 Volume as the Date-Strike Curve Steepens
This is a price-ladder market: each date is its own binary, where “Yes” reflects the chance the specified action occurs on that specific day, not a single pooled probability for the whole month. The front of the curve still prices near-term risk as dominant—July 12 trades 64.5% Yes / 35.5% No and July 13 trades 66.5% Yes / 33.5% No—while later dates steeply discount, like July 14 at 37.5% Yes / 62.5% No and July 20 at 16.5% Yes / 83.5% No. The headline-triggered downtick is sharp at the lead strike (down from 82.5% to 66.5%), yet the historical summary simultaneously flags high volatility and reversal_detected, which fits a market that has been whipsawing between fast-risk and de-escalation interpretations rather than converging smoothly. With $519,984 matched and “consensus: strengthening” alongside “trend: bearish,” the most defensible read is that traders are narrowing toward a specific early window (around July 12–13) even as they reduce confidence from prior highs.
Watch whether the ladder’s curve flattens (later dates rising toward the front) or steepens (July 12–13 holding up while July 14+ fades), since that shape change is the clearest signal of traders shifting from “imminent” timing to “delayed or not on a specific day” timing into the 2026-07-31 resolution deadline.

If you’re managing timing risk on this ladder, it helps to keep an eye on adjacent Polymarket contracts that capture the same headline flow through different resolution mechanics. Traders have been especially active in “Iran leader end of 2026?” (79.55%, $26,773,557 volume) and the shipping-focused “Strait of Hormuz traffic returns to normal by July 31?” (95.5%, $15,693,532 volume), while the nearer-dated “Strait of Hormuz traffic returns to normal by July 15?” sits at 99.65% on $9,419,896. For a more operational read-through, “Iran full airspace closure by...?” is pricing its lead at 33.0% ($3,232,894 volume), offering another way to gauge whether traders see disruption as transient or persistent.
