Market context
Ships are moving through the Strait of Hormuz again after a months-long blockade, but traffic remains volatile following missile attacks on commercial tankers over the weekend. Iran’s Revolutionary Guard Corps fired at least two missiles at vessels on 7 July, damaging a Saudi-flagged crude tanker and causing a fire on another, yet Kpler data confirmed 108 verified crossings over the preceding weekend, with 43 on 3 July, 34 on 4 July, and 31 on 5 July[3]. This resilience suggests the 82% crowd-implied probability for a specific transit threshold is grounded in a genuine recovery trend, though volumes remain well below pre-conflict levels[5].
Historically, similar post-blockade reopenings in choke points show sharp initial rebounds followed by instability when security threats persist. The current week’s activity mirrors the June 20 surge of 55 merchant ships when US forces supported freedom of navigation, yet the July attacks introduce a new risk of sudden drops if Iran escalates[4]. Traders should watch for UK Maritime Trade Operations advisories and any IRGC statements, as the settlement depends entirely on IMF Portwatch’s finalized transit calls, which exclude unreported vessels[3]. A temporary cease-fire last month enabled this recovery, but the absence of a durable resolution keeps the flow fragile[5].

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.
- 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.
- 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.
