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, yet daily vessel transits have fallen sharply from historical norms. A 7-day moving average of 60 arrivals would represent a return to pre-disruption baseline traffic; current data sits substantially below this threshold. The resolution hinges on IMF Portwatch data publication, which tracks container, tanker, bulk, and general cargo arrivals through one of the world's most strategically sensitive chokepoints.

Historical precedent suggests sustained normalisation is difficult to achieve. During the 2022 Red Sea crisis and subsequent Houthi attacks on shipping, transit calls declined for months before recovering unevenly. The 2019–2020 period following the Soleimani assassination saw comparable volatility, with traffic taking quarters to stabilise. A 1% crowd probability reflects the high bar: not merely a temporary uptick, but a sustained 7-day average at or above 60 calls, publishable by end-May 2026. This implies either a comprehensive regional security resolution or a fundamental shift in shipping routing that reverses course within eighteen months.

Traders should monitor announcements from the US Fifth Fleet, Iranian Revolutionary Guard statements, and Houthi military communiqués, as these typically precede operational changes. Shipping indices and Lloyd's List reports offer near-real-time context on rerouting decisions and insurance costs, which directly influence whether vessels attempt transit. Any major escalation in the Red Sea or Persian Gulf would likely extend the recovery timeline beyond the settlement window. Conversely, a formal ceasefire agreement or international naval coordination announcement could accelerate normalisation, though historical patterns suggest even then the transition takes months.

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.
