Strait of Hormuz traffic returns to normal by 2026?

Platform comparison

Market context

The Strait of Hormuz is still operating far below normal, so this market is effectively a bet on a sustained and measurable shipping recovery rather than a single headline about reopening. Reuters reported only two to seven transits on several July days, with traffic described as a near standstill or the lowest in two months, while the Strait-of-Hormuz monitor says the waterway remained closed with near-zero transits against a normal of about 60 a day.[8][10][1]

That framing matters because the market’s threshold is not “open” but a 7-day moving average of at least 60 arrivals, which is closer to a full pre-crisis restoration than a partial rebound. Reuters and other shipping data providers have described the route as repeatedly reopening and then deteriorating again, while June reporting suggested traffic had recovered only to about half peacetime levels before later setbacks.[4][6][12] On current crowd-implied odds, the 6% YES price on Polymarket implies a very low chance of a weekly average hitting that benchmark before 31 August, and the comparison with Kalshi, Betfair and Smarkets is mainly about how that view is expressed: Polymarket quotes direct implied probability, whereas exchange-style books typically show decimal odds and can differ materially once fees, spreads and access rules are applied.

The main catalysts are any fresh U.S.-Iran maritime or sanctions announcements, security incidents in or near the Gulf, and operational updates from ship-tracking services that could affect the 7-day average. Reuters has linked previous swings in Hormuz traffic to renewed strikes, retaliation risk and changes in blockade or passage terms, while a preliminary reopening deal in June was paired with technical and military caveats, including mine-clearance issues and a 60-day fee waiver.[11][9][12] For traders comparing platforms, KYC reach and jurisdiction matter as much as price: predictive markets available to UK users may differ from offshore or geoblocked venues, and some books will be more accessible but less transparent on fees, while others may offer tighter pricing but stricter verification.
