Market context
A preliminary peace memorandum between the United States and Iran has already been electronically authorised by President Trump and Iranian President Masoud Pezeshkian, ending a three-and-half-month conflict and reopening the Strait of Hormuz[1][2]. This interim accord, which includes Iran’s reaffirmation that it will not develop nuclear weapons, triggers a 60-day window to negotiate a final deal, with a ceremonial signing scheduled in Switzerland on 19 June[1][5]. Despite this progress, the market’s 3% probability reflects uncertainty over whether the listed individual will formally sign a binding written agreement by July 31, 2026, as the current memorandum remains a non-binding framework subject to further negotiation[1][3].
Historically, comparable US-Iran deals, such as the 2015 JCPOA, required years of multilateral negotiation and faced significant domestic and international hurdles before finalisation[2]. The current 60-day timeline is unusually short, and early reporting suggests Tehran may retain uranium enrichment capabilities and proxy networks, complicating the path to a definitive agreement[3]. Traders should monitor Vance’s upcoming visit to Switzerland for the ceremonial signing, any extensions to the 60-day negotiation window, and whether Iran imposes transit fees on the Strait of Hormuz after the initial period expires[1][3]. Key dependencies include the US lifting all sanctions, unfreezing Iranian assets, and the U.N. Security Council ratifying the deal’s executive mechanism[2][6].

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.
- 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.
- 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.
- 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.
- 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.
