Market context
Iran is actively pursuing a policy to impose mandatory maritime service fees on commercial vessels passing through the Strait of Hormuz, a move that directly contradicts the recent US-Iran peace deal which stipulated toll-free passage for a 60-day negotiation window[1][2]. While Oman has proposed a voluntary fee model similar to the Straits of Malacca and Singapore, Iranian officials insist the charges must be obligatory, with Tehran threatening to impose its own unilateral fees if no agreement is reached with Oman[1][5]. This historical friction frames the current 2% crowd-implied probability, as the temporary ceasefire agreement explicitly bans charges during its validity, yet Iran has already inserted amendments allowing for future fees once the negotiation period expires[3][4].
Traders must monitor official announcements from Iran’s Strait of Hormuz body regarding the transition from the current fee waiver to a mandatory collection system, particularly as the 60-day window nears its end[2]. Key catalysts include any formal declaration by Iran’s deputy foreign minister confirming the imposition of unilateral fees, which he stated would occur if Oman refuses to compromise[1]. Additionally, watch for shifts in US diplomatic pressure, as President Trump has publicly warned Iran against charging tolls while simultaneously suggesting a joint venture to secure the route[6]. The settlement of this market hinges on whether Iran officially announces and begins collecting these mandatory fees before the settlement deadline in August 2026, a scenario that remains unlikely given the current diplomatic constraints but is technically possible if the peace deal collapses[7][8].

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.
- 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.
- 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.
