Market context
The Strait of Hormuz remains effectively closed to outbound commercial shipping as of late June 2026, with zero verified vessel movements recorded over the past 72 hours. This severe bottleneck has halted the transit of tankers, dry bulk, and container ships, creating an alarming absence of live traffic through the critical choke point that links the Persian Gulf to global markets.
Historically, similar chokepoint closures have shown fleeting recoveries; the strait reopened briefly on 21 April 2026 before closing again the following day[2]. Such volatility frames the current 9% crowd-implied probability as a realistic assessment of the difficulty in sustaining a seven-day moving average above 60 arrivals. Programmatically, a power-user would script a conditional order to trigger only if IMF PortWatch data confirms a sustained rebound, rather than betting on a single transient spike that mirrors the April failure.
Traders must monitor war risk insurance premiums, peace talk status, and official announcements from Iranian and US maritime authorities, as these dependencies dictate reopening timelines. Recent MarineTraffic data indicated at least 50 vessels transited in a single 24-hour window during the April reopening, yet this proved unsustainable[7]. The immediate catalyst is any shift in the current blockade, which remains the primary barrier to the market resolving to "Yes" before the 7 July settlement deadline.
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 Bot 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.
