Market context
The Strait of Hormuz has surged to its highest traffic level in two months following a deal to halt the US-Iran war, with 25 commercial vessels crossing on Thursday—more than triple the daily average recorded since early March[1]. This reopening stems from a memorandum of understanding finalized on June 17, which guarantees immediate commercial navigation and requires the US to lift its naval blockade of Iranian ports by July 19[2]. Prior to the conflict, approximately 20% of global oil production passed through this chokepoint, but tanker traffic had previously dropped to zero as war risk cover was pulled by P&I clubs[3].
Historical precedent suggests that even after ceasefire announcements, commercial traffic often remains restricted for weeks due to routing uncertainty; in April 2026, despite a ceasefire, only six vessels navigated the strait daily[4]. The current 17% probability reflects this pattern of delayed recovery, as the agreement does not clarify whether Iran will ultimately maintain authority or impose tolls after the initial 60-day toll-free period[2]. Traders should monitor the July 19 deadline for the US blockade lift, as failure to meet this could trigger renewed closures, while also watching for real-time data from Kpler and AXSMarine to confirm sustained volume above the 60-ship threshold[2]. The settlement window ends 31 July 2026, leaving just over a month for traffic to stabilise before the market resolves[2].

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.
- Can I bet on individual matches?
- Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.
- 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.
- Can I import form data and lineups?
- This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
