Market context
The Strait of Hormuz, through which roughly one-fifth of global seaborne oil transits, has experienced significant traffic disruption since late 2024 owing to regional tensions, Houthi attacks on vessels, and insurance cost spikes. This market settles on whether IMF Portwatch data shows a 7-day moving average of at least 60 daily transit calls—a threshold representing approximate normalcy—by mid-July 2026. The metric captures all major commercial vessel classes: container ships, tankers, bulk carriers, and general cargo vessels.
Historical precedent suggests recovery timelines vary sharply depending on conflict resolution pace. The 2022 Russia–Ukraine war disrupted Black Sea grain exports for months despite no direct blockade of the Suez Canal; by contrast, the 2019 Strait tanker incidents resolved within weeks once insurance premiums stabilised. The current 54% YES probability on Polymarket (displayed as 1.85 decimal odds on Kalshi's equivalent book) reflects genuine uncertainty about whether diplomatic channels or military de-escalation will materialise within eighteen months. Betfair's higher liquidity on geopolitical events may show tighter spreads here, whilst Smarkets' lower fees (0.2% versus Kalshi's standard 2%) could attract volume from high-frequency traders arbitraging minor probability shifts.
Traders should monitor announcements from the International Maritime Organization, US Navy statements on Strait patrols, and Iranian nuclear negotiations—all potential catalysts for either sustained tension or rapid normalisation. Lloyd's List and Splash247 publish weekly transit data; divergence between those sources and IMF Portwatch's eventual figures could create settlement disputes, though IMF data remains the contractual arbiter.
Methodology
We read Strait of Hormuz traffic returns to normal by July 15? 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
Settlement is the biggest difference between the four platforms: Polymarket on-chain in USDC (instant), Kalshi USD via CFTC (T+1), Betfair and Smarkets in local currency via bank withdrawal (T+1 to T+3). Kalshi Alternative UK routes every trade directly into Polymarket's on-chain settlement, which is why payouts land fastest.
