Market context
The Strait of Hormuz remains effectively closed as the Iran war continues, with transit calls near zero for weeks and oil prices surging over 30% since March[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]. The passage, which once carried 20% of global oil and gas, was briefly reopened on 21 April 2026 but closed again the following day, leaving commercial shipping suspended[2].
Historically, such closures have persisted for months unless a major geopolitical shift occurs; the 8% crowd-implied probability reflects this entrenched stagnation, as no sustained recovery has materialised since the April reversal[2]. Programmatic traders should monitor IMF PortWatch’s 7-day moving average directly via API, setting conditional orders to trigger only if the metric hits 60, while cross-referencing MarineTraffic or ShipFinder data to account for ships altering GPS tracking during transit[1][4]. Key catalysts include Trump’s next diplomatic statement on Iran, any announced naval de-escalation, and real-time updates from the Strait of Hormuz Live Tracker, which now flags war-risk insurance premiums and stranded vessel counts hourly[2]. Recent NBC News reporting confirms that actual transit figures may be higher than reported due to GPS spoofing, a critical nuance for algorithmic validation[1].
Methodology
This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Polymarket Review UK, which mirrors the Polymarket order book directly.
Resolution & payout
Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.
Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
FAQ
- Is this market available outside the US?
- Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.
- What's the difference between YES and NO shares?
- A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.
- What does Polymarket cost to trade?
- Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.
- How fast are USDC deposits?
- Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.
- Do I need to KYC for this market?
- On Polymarket directly, no — it's wallet-based. Intermediary brokers like Polymarket Review UK trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
