Strait of Hormuz traffic returns to normal by end of June?

Platform comparison

Market context

The Strait of Hormuz, through which roughly one-fifth of global seaborne oil passes, has experienced significant traffic disruption since late 2023 following Houthi attacks on commercial vessels and subsequent regional tensions. The market asks whether daily transit calls—measured as a seven-day rolling average by IMF Portwatch—will recover to 60 or above by the end of June 2026. This threshold represents a return to pre-disruption baseline levels. The current 51% implied probability reflects genuine uncertainty about whether geopolitical de-escalation or alternative routing will dominate shipping behaviour over the next eighteen months.

Historical precedent suggests shipping chooses efficiency over caution once risk premiums stabilise. The 2022 Russia-Ukraine blockade of Ukrainian grain exports saw rapid rerouting rather than sustained traffic collapse; within months, alternative corridors absorbed displaced cargo. However, the Hormuz situation differs in that no viable bypass exists for tanker traffic at comparable cost, creating structural dependency. Previous disruptions—the 1980s tanker war, the 2019 drone attacks—saw recovery timescales of three to six months once political signalling shifted. Current data from Lloyd's List Intelligence (January 2025) shows transit calls averaging 45–52 daily, meaning the market requires roughly a 15–30% increase from present levels.

Traders should monitor Iranian nuclear negotiations, US sanctions policy shifts, and Houthi ceasefire discussions as primary catalysts. Kalshi's US-domiciled order book may reflect American geopolitical risk assessments more sharply than Polymarket's global liquidity; Betfair and Smarkets typically show tighter spreads on macro events with longer settlement windows. IMF Portwatch data publication lags by approximately one week, meaning resolution could occur as early as mid-June if recovery accelerates suddenly.

Methodology

We read Strait of Hormuz traffic returns to normal by end of June? from four platform perspectives: Polymarket (on-chain CLOB), Kalshi (CFTC-regulated exchange), Betfair Exchange (sports book exchange), Smarkets (peer-to-peer betting exchange). Polymarket's live quote comes directly from the Polygon order book; the other three are listed with their platform attributes — fees, KYC, settlement currency, payment options — because a 1:1 contract comparison without API access would be guesswork.

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.
