Polymarket odds sink to 4.5% on Hormuz traffic normalization by July 31

Polymarket Slashes “Hormuz Traffic Back to Normal by July 31” Odds After Renewed Shipping Security Shock

Polymarket traders are now pricing just a 4.5% chance that Strait of Hormuz traffic returns to normal by July 31, with “No” leading at 95.5% on $13.82M matched. The shift comes as a renewed security cloud over the waterway collides with a market that has swung sharply from earlier expectations of normalization.

Key Takeaways

• Prediction: “No” leads at 95.5% (Yes 4.5%) on Polymarket for traffic returning to normal by July 31.
• Basis: The contract repriced toward disruption risk as the latest news describes fresh ship attacks and escalating US-Iran strikes, weakening the path to “normal” traffic.
• Timing: The market resolves on 2026-07-31; the recent tape shows a sharp downside move, with historical_summary change_24h and change_7d both at -5.5 pp.

A report describes renewed uncertainty after a June 17 US-Iran MoU meant to restore shipping: multiple commercial vessels were attacked in and around the Strait of Hormuz, the US and Iran traded escalatory strikes, and Iran threatened to shut the strait again. The piece also cites post-reopening traffic remaining far below pre-war levels, with PortWatch data showing 513 transits from June 18 to July 5 (about 28 per day) versus a pre-war pace of about 100 per day.

Odds & Liquidity Snapshot: Yes 4.5% vs No 95.5% on $13.82M Matched, With a 37.5 pp Reprice From 42%

This is a binary Polymarket contract: a “Yes” share represents the market’s probability that traffic is deemed “back to normal” by the July 31 resolution date, and “No” covers every outcome short of that threshold. Pricing is heavily one-sided at Yes 4.5% / No 95.5% on $13,817,163 matched, signaling tight consensus around non-normalization rather than a balanced debate. The move has been decisively downward versus earlier levels (previous_odds 42.0% to current_odds 4.5%, a 37.5 pp drop in the current snapshot), aligning with a bearish, strong-momentum, high-volatility profile in the historical_summary and a strengthening consensus. At the same time, reversal_detected=true flags that the path hasn’t been smooth, so traders should treat any near-term bounce as part of a choppy repricing process rather than a clean trendline.

Watch whether the market holds below ~5% Yes or snaps back toward the prior 42% area; with volatility marked high and reversal_detected=true, even small updates to the “normal traffic” interpretation could move probabilities quickly ahead of the 2026-07-31 resolution.

On the nearer-term disruption tape, “Iran full airspace closure by…?” has 28.0% on August 31 ($2,361,225) and “US announces blockade on Iran by…?” sits at 42.5% for December 31 ($1,699,664), giving traders a quick read across diplomatic, leadership, and escalation-linked outcomes.
