Strait of Hormuz traffic returns to normal by August 31?

Platform comparison

Market context

Ships are barely moving through the Strait of Hormuz as the US-Iran war continues, with commercial traffic virtually shut off following Washington’s strike on Iranian military sites and Tehran’s retaliatory base targeting. The strait, which carries roughly 20% of global oil and 25% of LNG trade, has been closed since a brief reopening on 21 April 2026 ended the next day, leaving vessels stranded and daily economic losses exceeding $4 billion[1][3].

Historically, the strait has seen near-total closures during regional conflicts, but normalisation only follows explicit ceasefire deals or major de-escalation. The 20% crowd-implied probability for a 60-ship 7-day average by August 31 reflects the lack of progress in peace negotiations and President Trump’s declaration of a naval blockade, which remains a prerequisite for any reopening[2][4]. Past data shows that even after brief reopenings, traffic collapses again without sustained diplomatic resolution, framing the current low odds as realistic rather than overly pessimistic.

Traders should monitor announcements on ceasefire talks, mine-clearing operations, and any shifts in US or Iranian naval posture. MarineTraffic data indicates that mine clearance could delay traffic restarts, while NBC News reports that actual vessel counts may be higher due to GPS spoofing during the conflict[4][6]. The key dependency is whether Tehran agrees to halt attacks on vessels and remove tolls, as Iran’s recent imposition of fees and implied mining of the strait effectively closed the route[4]. Without a breakthrough in negotiations, the 60-ship threshold remains unlikely before the settlement window closes.

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.

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.
