Strait of Hormuz traffic returns to normal by September 15?

Platform comparison

Market context

The Strait of Hormuz currently handles roughly 21–25 daily transits on a 7-day moving average, well below the 60-call threshold required for resolution. The market asks whether traffic will recover to pre-disruption levels—a benchmark last seen before regional tensions escalated in 2024. The 8% implied probability reflects consensus scepticism that normalisation will occur within the settlement window.

Historical precedent suggests Hormuz transit disruptions are sticky. The 2019 tanker attacks saw traffic dip sharply but recover within months once insurance and routing protocols stabilised. However, the current environment differs materially: Houthi drone and missile strikes have persisted across 2024 and into 2025, forcing shipping to divert via the Cape of Good Hope despite added cost and transit time. Previous recoveries followed discrete incidents; sustained campaign-level disruption has no close parallel in recent data. The 60-call target represents a 140–185% increase from current levels—a jump that demands either a dramatic security shift or acceptance of heightened risk by major carriers.

Watch for three catalysts: formal ceasefire announcements affecting Yemen, shifts in US naval posture in the region, and insurance premium adjustments that might make Hormuz transit economically viable again. Reuters reported in January 2025 that some container lines were exploring selective return to the strait if regional tensions eased, but no firm timeline emerged. Any material de-escalation would need to translate into carrier confidence within months to hit the September deadline. The consensus underestimates tail-risk scenarios—a sudden diplomatic breakthrough or major power intervention—but the base case of gradual normalisation remains a long shot given the persistence of current threats.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

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.
