Strait of Hormuz traffic returns to normal by July 31?

Platform comparison

Market context

The Strait of Hormuz handles roughly one-third of global maritime petroleum trade, making transit volumes a barometer of regional stability and energy markets. The 48% YES probability on Polymarket reflects genuine uncertainty about whether daily ship arrivals will average 60 or more across any seven-day window before end-July 2026. IMF Portwatch data forms the settlement mechanism, with the conditional token structure on Polygon meaning traders holding YES tokens receive USDC payouts only if that threshold is crossed and verified on-chain.

Historical precedent matters here. The strait saw sustained disruptions during 2019–2020 when tensions between Iran and the United States spiked, with transit calls dropping below 40 daily at their nadir. Recovery took months even after immediate military risks receded, as shipping insurers and operators rebuilt confidence. More recently, Houthi attacks on vessels in the Red Sea (2023–2024) redirected some traffic around the Cape of Good Hope, though Hormuz transits remained above 50 daily. The current 48% odds suggest the market prices meaningful risk that either geopolitical friction or alternative routing persists through mid-2026, rather than a swift return to pre-disruption norms of 70+ daily calls.

Traders should monitor Iranian nuclear negotiations and any escalation in regional proxy activity, particularly statements from Tehran or US policy shifts. Suez Canal throughput data offers a leading indicator—if Red Sea tensions ease and traffic consolidates back through Hormuz, the seven-day average could breach 60 within weeks. Conversely, any new sanctions regime or military incident would likely keep the market pinned below that threshold. IMF Portwatch publishes weekly, so settlement could occur suddenly once conditions align.

Methodology

We track Strait of Hormuz traffic returns to normal by July 31? on the five venues with material liquidity for prediction markets. Live odds come from the Polymarket Polygon order book — the only source that ships real-time data under an open licence. For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.

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.
