Strait of Hormuz traffic returns to normal by September 30?

Platform comparison

Market context

The key question is whether ship calls through the Strait of Hormuz can get back to a 7-day average of at least 60 before 30 September 2026, which is close to the pre-crisis norm but still far above the depressed levels seen earlier this year. Recent reporting has shown traffic recovering unevenly: Reuters said the strait was still at less than 10% of usual volumes in April, while later Kpler-based coverage in July put weekly transits at 53 vessels, down from 157 the prior week, implying a fragile and volatile rebound rather than a clean return to normality.[16][17] The current crowd-implied probability of **24% YES** is below the roughly **30%** price highlighted by Polymarket on X and below Paridesk’s reported range of about **22%–32%**, suggesting this contract is trading more pessimistically than broader market commentary.[1][2]

Historical analogues argue for caution in reading the recent bounce as durable. After the June ceasefire and reopening talk, multiple reports described ships trickling back, but analysts warned that backlog clearance, mine clearance, insurance costs, and security assurances could keep traffic well below normal for weeks or months.[5][11][13] That matters because this market does not settle on a promise of reopening; it settles only when IMF Portwatch actually publishes a 7-day moving average at or above 60, so temporary surges or non-reported vessels will not count.[2][6]

For traders, the main catalysts are any U.S.-Iran security or maritime-access announcements, changes in naval escort or mine-clearing arrangements, and the weekly shipping-data prints that can quickly shift sentiment. CNBC reported on 8 July that Kalshi traders had already cut the chance of normal traffic by 1 December to 43%, and later July coverage noted further deterioration in forward odds after traffic weakened again, underscoring how sensitive this contract is to fresh disruption headlines and to the next few IMF Portwatch updates.[3][18]

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Best Prediction Markets, which mirrors the Polymarket order book directly.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
