Polymarket odds crash to 4.5% on Hormuz traffic normalizing by July 31

Polymarket Reprices Strait of Hormuz “Traffic Normal by July 31” After Iran-Closure Headline

On Polymarket, traders are now pricing just a 4.5% chance that Strait of Hormuz traffic returns to normal by July 31, with “No” at 95.5% on $15.6M matched. The repricing follows a report that Iran declared the strait closed after an “unauthorized” vessel was hit, and the contract’s odds show how quickly the market moved from a coin-flip posture to near-certainty on disruption.

Key Takeaways

• Polymarket’s leading outcome is “No” at 95.5% (Yes 4.5%) for traffic returning to normal by July 31.
• The odds collapsed from 42.0% Yes to 4.5% Yes, signaling traders heavily marked down the normalization scenario after the closure claim.
• The contract resolves on 2026-07-31, and the latest read shows a bearish, strong-momentum tape with reversal_detected=true and high volatility.

A report says Iran declared the Strait of Hormuz closed after an “unauthorized” vessel was hit. The claim centers on the status of shipping through the strait and frames a near-term risk of continued disruption rather than a quick return to normal traffic conditions.

Odds Collapse to 4.5% Yes (95.5% No) as $15.6M Matched Concentrates Liquidity Into Disruption

This is a binary Polymarket contract: a “Yes” share only pays out if the resolution criteria determine traffic returned to normal by 2026-07-31, so the 4.5% Yes price is the market’s implied probability for that outcome. The move is extreme: current Yes odds are 4.5% versus a previous 42.0%, a 37.5 percentage-point drop, with total matched volume at $15,594,517—suggesting the market shifted from meaningful disagreement to a lopsided consensus toward “No.” The historical summary flags a bearish trend with strong momentum and high volatility, and reversal_detected=true alongside weak consensus; that mix fits a tape where traders have repeatedly repriced, but the latest pricing still concentrates heavily on the disruption scenario. Compared with slower narrative-driven updates, this contract continuously translates each new headline into a single, tradable probability that must hold through the July 31 settlement window.

Watch whether the Yes price can recover from the low single digits: any sustained move back above the historical avg_last_5 of 51.0 would signal a major reassessment. Until then, the key market-structure question is whether new information narrows the “high volatility / weak consensus” profile or keeps the contract pinned near “No” into the 2026-07-31 resolution.

Taken together, these contracts give traders a quick way to compare how the market is distributing probability across near-term disruptions, longer-dated escalations, and leadership/endgame scenarios—without relying on a single headline or settlement date.
