Strait of Hormuz traffic returns to normal by end of May?

Platform comparison

Market context

The Strait of Hormuz handles roughly one-third of global seaborne oil trade. A 7-day moving average of 60 daily transit calls would represent a return to pre-disruption baseline traffic; current levels are substantially depressed. The market hinges on whether commercial shipping patterns normalise by the end of May 2026, measured by IMF Portwatch arrival data across container, tanker, dry bulk, and general cargo vessels.

Historical precedent matters here. The strait experienced significant traffic reductions following the October 2024 Houthi attacks on shipping and subsequent regional escalation. Recovery timelines for comparable disruptions—the 2022 Russia-Ukraine blockade of Ukrainian ports, or the 2021 Suez Canal blockage—show that normalisation typically requires 6–18 months once underlying geopolitical tension eases. The 1% implied probability reflects market scepticism that conditions will stabilise sufficiently within 18 months, particularly given ongoing tensions in the Red Sea and broader regional instability.

Traders should monitor announcements from the International Maritime Organization, shipping insurance premium movements, and statements from Iran or Gulf Cooperation Council nations regarding corridor security. Recent reporting from Lloyd's List and Splash247 indicates that insurers remain cautious on transit risk premiums. Any formal ceasefire agreement, demilitarisation accord, or international naval escort commitment would shift expectations materially. The settlement depends entirely on IMF Portwatch publication schedules; delays in data release could affect resolution timing. Funding your position via SEPA or Klarna allows flexibility if you wish to adjust exposure as regional developments unfold through early 2026.

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

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.

Polymarket Klarna UK is available in most jurisdictions where Polymarket isn't directly accessible. Polymarket itself is geo-blocked in the US/UK/EU. Always check local regulations.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

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.
