Market context
The Strait of Hormuz handles roughly one-third of global seaborne oil trade, making transit volumes a barometer of regional stability and international commerce. This market tracks whether daily ship arrivals—measured as a seven-day moving average by IMF Portwatch—will recover to 60 or above by mid-July 2026. The threshold represents a return to pre-disruption baseline traffic; current levels reflect ongoing tensions, including Iranian naval activity, Houthi attacks on vessels, and US-led coalition operations that have intermittently constrained passage since late 2023.
Historical precedent suggests recovery timelines depend on geopolitical settlement rather than gradual normalisation. The 2019 tanker attacks saw transit calls drop sharply but rebound within weeks once insurance and routing protocols stabilised. By contrast, the 2022 Russian invasion of Ukraine created sustained shipping reroutes that took months to unwind. The current 53 per cent crowd probability reflects genuine uncertainty: traders are pricing in a roughly even chance that either diplomatic progress materialises or disruption persists through the settlement window.
Key catalysts include any formal ceasefire agreement involving Yemen's Houthis, shifts in US policy toward Iran, or declarations by major shipping insurers that corridor risk has diminished sufficiently to resume standard routing. IMF Portwatch publishes data weekly; traders should monitor announcements from the International Maritime Organization and shipping indices tracking Hormuz transits. Regulatory accessibility for UK residents follows the German GlüStV framework—prediction markets registered under equivalent oversight permit trading without KYC requirements up to £1,200 notional exposure, though larger positions trigger standard identity verification under CFTC reach provisions affecting cross-border US participation.
Methodology
We track Strait of Hormuz traffic returns to normal by July 15? 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
At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.
On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
