Market context
Ship traffic through the Strait of Hormuz has been nearly halted for weeks due to the ongoing conflict with Iran, sending oil prices higher and disrupting a route that carries roughly 20% of global oil and gas supply[1]. President Trump has declared the strait’s reopening a prerequisite for any ceasefire with Tehran, yet peace negotiations show minimal progress and he has imposed a naval blockade against Iran[1]. Tehran has implied it may have laid mines in the passage, while Iranian media released maps indicating safe routes for incoming and outgoing vessels[1].
Historically, such standstills in Hormuz have persisted for months until geopolitical pressure forces a resolution; the 5% crowd-implied probability reflects this entrenched reality, as comparable disruptions in the 1980s and 2010s saw traffic remain below 60 ships per day for extended periods[1][3]. Current data shows a 7-day moving average of just 13.14 vessels as of 21 June 2026, far below the 60-ships threshold required for “normal” traffic[6]. Programmatic traders would model this by setting conditional orders that trigger only if IMF PortWatch publishes a 7-day average above 60, using bots to monitor real-time feeds from PortWatch and MarineTraffic[4][5].
Key catalysts to watch include Trump’s next ceasefire announcement schedule, any Iranian naval blockade adjustments, and updates on mine-clearing operations in the strait[1]. A recent NBC News report confirms that actual vessel figures may be higher than reported since some ships alter GPS tracking, but the blockade remains effective[1]. Traders should monitor IMF PortWatch’s daily transit calls for container, dry bulk, roll-on/roll-off, general cargo, and tanker ships, as only these are counted toward the settlement metric[1]. The settlement window ends 30 June 2026, leaving little time for a sudden surge to 60 ships without a major geopolitical shift[1].
Methodology
Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.
Resolution & payout
At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.
On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
