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 passes, has experienced sustained traffic disruption since late 2024 following regional tensions and Houthi attacks on merchant vessels. The market asks whether daily transit calls—measured as a seven-day moving average across container, tanker, dry bulk, and general cargo ships tracked by IMF Portwatch—will recover to 60 or above by mid-June 2026. The 9% implied probability reflects the market's assessment that normalisation within eighteen months remains unlikely, though the resolution criterion is specific: any single publication date meeting the threshold triggers a "Yes" outcome.

Historical precedent suggests recovery timelines vary sharply by disruption type. The 2022 Russia–Ukraine war saw Black Sea grain corridor traffic collapse and partially reroute for over a year; the 2021 Suez Canal blockage resolved in days once the Ever Given was refloated. Hormuz disruptions tend toward the longer end because they involve sustained geopolitical risk rather than mechanical obstruction. Pre-disruption Hormuz traffic typically averaged 70–80 daily transits; reaching 60 would represent a 75–85% recovery rather than full normalisation. Traders comparing Polymarket's 1.11 decimal odds against Kalshi's equivalent pricing should note that Kalshi's tighter KYC requirements and US-only access may suppress liquidity on this geopolitically sensitive route, whilst Smarkets and Betfair's broader international reach could offer deeper books.

Catalysts include any de-escalation announcements from Iran, the US, or Gulf states; shipping insurance premium shifts; and monthly IMF Portwatch releases themselves, which carry settlement risk if data revisions occur. Recent reports from Lloyd's List and maritime security firms indicate Houthi attack frequency has stabilised rather than intensified, though no formal ceasefire exists. Traders should monitor US policy shifts post-January 2025 and any OPEC production adjustments, both of which could alter incentives for tanker routing through the Strait.

Methodology

This page compares Strait of Hormuz traffic returns to normal by June 15? specifically across Polymarket, Kalshi, Betfair Exchange and Smarkets. Live odds come from the Polymarket order book; the other venues' contract details are maintained manually because their APIs aren't directly comparable. Every CTA routes to Polymarket Alternative, which mirrors the Polymarket order book at 0% fees.

Resolution & payout

Polymarket settles via UMA Optimistic Oracle on Polygon. A proposer posts the outcome with a bond, the two-hour window runs, then the smart contract pays USDC.

Kalshi settles USD through the CFTC-regulated clearinghouse — the cleanest variant, with heavier KYC. Betfair Exchange settles in account currency (GBP/EUR), net of 2-5% commission. Smarkets follows the same model as Betfair with a lower default 2% commission.
