Market context
Ships are returning to the Strait of Hormuz after a deal halted the US-Iran war, with 25 commercial vessels crossing on Thursday—more than triple the daily average since March. This surge marks the highest volume since April, following a memorandum guaranteeing immediate reopening of the waterway. However, the strait remains effectively closed for most traffic, with only low-risk transits recorded recently, and war risk cover still expired for many tanker owners.
Historically, this is the first operational closure of the Strait in modern history, lasting exactly 100 days as of June 8, 2026. Pre-war, over 150 ships passed daily; now, traffic has dropped precipitously to as few as 18 on 1 March. Comparable disruptions, such as the brief April 21 reopening that closed again the next day, show volatility rather than sustained recovery. With current crowd-implied probability at 0%, the market reflects that reaching 60 ships in a 7-day average by June 30, 2026, is highly unlikely given the persistent risk and insurance barriers.
Traders should watch the US naval blockade lift on July 19, Iran’s commitment to restore pre-war traffic levels, and whether P&I clubs reinstate war risk cover. Recent reports note ships rerouting via the Cape of Good Hope, adding 14 days and soaring costs, while some owners still transit without AIS despite extreme danger. A beat-reporter from AFP News confirms the surge but cautions that overall activity remains below normal despite diplomatic progress, suggesting the 60-ship threshold remains out of reach before the settlement window closes.

FAQ
- Are prediction markets better than sports betting?
- Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.
- 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.
- 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.
