Market context
Ship traffic through the Strait of Hormuz remains severely depressed following the 2026 Iran conflict, with daily transits hovering around 40 vessels—well below the 60-ships threshold required for this market to resolve YES. Historical data shows traffic dropped by over 95% at the crisis peak, falling from roughly 100 daily vessels to single digits for non-Iranian ships [4][3]. Even after the US–Iran ceasefire on 8 April and a subsequent navigation agreement on 17 June, volumes have only partially rebounded, stabilising between 30 and 60 crossings weekly rather than returning to prewar norms [7][8]. The current 52% crowd-implied probability reflects cautious optimism that the 60-day negotiation window, which began in June, will clear logistical bottlenecks like mine removal and restore permission protocols [9].
Traders should monitor the expiry of the 60-day US–Iran negotiation phase in mid-August, when Iran’s commitment to prewar transit practices without fees could end [9]. Key catalysts include weekly Kpler and AXSMarine transit reports, which recently showed 25 commercial vessels passing on a single day—the highest since April—but also highlighted persistent ambiguity over which authorities grant traversal permission [7][8]. The removal of the US naval blockade on Iranian vessels in April was a necessary precondition, yet shipping firms remain cautious due to anchored fleets and damaged Gulf energy infrastructure [9]. A sustained 7-day moving average above 60 requires roughly 91 total transits over seven consecutive days, a target unlikely without full clearance of underwater mines and resolved security guarantees [5].

FAQ
- When do sports markets resolve?
- Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.
- What are live sports odds on Polymarket?
- Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.
- Which sports markets are available?
- Football (soccer) dominates — Champions League, World Cup, Premier League, La Liga, Bundesliga — followed by NFL, NBA, tennis Grand Slams, Formula 1, boxing/MMA. Resolution via official league source confirmation.
- How fast do sports winnings settle?
- Once the official league outcome is logged in the UMA Oracle (typically 1-2 hours after the final whistle), Polymarket's smart contract triggers USDC payout. To your wallet within minutes.
- What's the difference between match odds and outright odds?
- Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.
