Strait of Hormuz traffic returns to normal by June 15?

Platform comparison

Market context

The Strait of Hormuz, through which roughly one-fifth of global seaborne oil transits, has experienced significant disruption since mid-2024 owing to Houthi attacks on commercial vessels and subsequent regional tensions. A return to "normal" traffic—defined here as a 7-day moving average of 60 or more daily transit calls across all vessel types—would require sustained de-escalation and restoration of insurer confidence in the corridor. Historical baseline data from 2022–2023 showed the strait regularly exceeding 80 daily transits; the current 18% probability reflects market scepticism that conditions will stabilise sufficiently within eighteen months.

Comparable disruptions offer limited precedent for recovery timelines. The 2019–2020 tanker war saw traffic decline sharply but rebounded within months once US naval presence increased and attack frequency fell. However, the current situation involves non-state actors with decentralised command structures, making predictability harder. The IMF Portwatch dataset, which this market relies upon, captures only vessels formally reported through official channels; unreported diversions via alternative routes (the Suez Canal alternative adds 6,000 nautical miles) would mask partial recovery.

Traders should monitor Houthi attack announcements, US and regional military posture statements, and insurance premium movements—all leading indicators of perceived risk. The UN-brokered ceasefire talks scheduled for early 2025 represent a key catalyst. Additionally, any major shipping line announcement to resume direct transits would likely precede the IMF data threshold by weeks, providing early signal. The settlement window closes 15 June 2026; absent a dramatic security shift by Q1 2026, achieving 60 daily calls appears structurally unlikely given current diversion patterns.

Methodology

We track Strait of Hormuz traffic returns to normal by June 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.

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
