Market context
The Strait of Hormuz handles roughly one-third of global seaborne oil trade, with daily transit calls typically ranging between 60 and 80 vessels before recent disruptions. Since late 2023, Houthi attacks on shipping, Iranian ballistic missile strikes, and Israeli military operations have reduced traffic substantially. The market's resolution criterion—a 7-day moving average of 60 transit calls as published by IMF Portwatch—represents a return to the lower bound of historical normality rather than pre-disruption peaks, yet the 7% implied probability reflects genuine scepticism about achieving even this threshold by June 2026.
Historical precedent suggests prolonged recovery timelines. During the 2019–2020 tanker crisis and subsequent sanctions escalation, Hormuz traffic took 18–24 months to stabilise at pre-shock levels. The current conflict ecosystem differs: Houthi operations remain operationally embedded despite US and coalition strikes, whilst Iranian regional posture remains assertive. Insurance premiums, rerouting via the Cape of Good Hope, and vessel operator caution persist as structural headwinds independent of any single ceasefire announcement.
Key catalysts include announcements of US–Iran nuclear negotiations, formal Houthi de-escalation commitments, or demonstrable cessation of attacks over a 60–90 day window. Traders should monitor IMF Portwatch data releases directly and cross-reference against Lloyd's List Intelligence for independent transit verification. Regulatory access varies: German traders face GlüStV classification scrutiny for derivatives; US CFTC reach extends to US persons regardless of platform jurisdiction; markets permitting no-KYC participation up to £1,500 notional exposure typically exclude geopolitical derivatives, so verification of your platform's specific settlement and custody arrangements remains essential before committing capital.
Methodology
This page reviews Strait of Hormuz traffic returns to normal by end of June? across five venues. We show live odds for Polymarket-based markets (sourced from the Polygon order book); for other venues we list platform attributes, since the comparable contracts are not exposed via a public API on every venue. Every CTA points at Polymarket Legal UK — the application we operate, where you trade directly against the Polymarket order book at 0% fees.
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.
