Market context
Traffic through the Strait of Hormuz is still being read as a gradual reopening story rather than a clean snap-back to pre-crisis levels. In June, Reuters reported that traffic remained far below normal despite a ceasefire, with only seven ships in 24 hours versus about 140 normally, while later reporting noted movement was improving but still short of pre-war throughput. [16][17]
That backdrop matters because the market has already swung with each sign of de-escalation. CNBC reported in June that Kalshi traders saw a 66% chance traffic would *not* return to normal before January, while subsequent coverage in July showed those odds moving lower as confidence in a year-end recovery weakened. [18][9] The current 56% Yes price sits in the middle of that range, suggesting traders expect improvement but not a smooth return.
The main catalysts are diplomatic and operational: any extension or breakdown in U.S.-Iran talks, changes to shipping guarantees, naval posture, mine-clearing progress, and whether carriers are willing to resume standard routing. A June New York Times report said the reopening agreement still faced “technical and military challenges”, including clearing mines, which implies that headline peace terms may not translate quickly into the IMF PortWatch 7-day average needed for settlement. [17] Traders will also watch whether PortWatch prints get back to the 60-transit threshold and stay there, since the contract resolves on a published moving average, not a one-day spike. [1]

FAQ
- 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.
- 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.
- 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.
