Strait of Hormuz traffic returns to normal by December 31?

Platform comparison

Market context

The Strait of Hormuz, through which roughly one-fifth of global seaborne oil transits daily, has experienced significant traffic disruptions since early 2024 following Houthi attacks on commercial vessels and subsequent regional tensions. The resolution criterion—a 7-day moving average of at least 60 daily transit calls as measured by IMF Portwatch—benchmarks recovery against pre-disruption norms. Historical data shows the corridor typically handled 60–80 daily transits before the escalation; the 60-call threshold thus represents a meaningful but not full normalisation, allowing for some residual caution among operators whilst acknowledging resumed commercial confidence.

Comparable precedents suggest recovery timelines vary sharply by trigger. The 2019 tanker attacks saw traffic rebound within weeks once insurance and routing protocols stabilised; the 2022 Russia–Ukraine blockade of Ukrainian ports took months to offset via alternative routes. Current Houthi activity remains episodic rather than systematic, which favours faster recovery, though any major incident—a direct hit on a large vessel, a US or allied military escalation, or Iranian involvement—could reset expectations materially. Traders should monitor shipping insurance premiums, which remain elevated, and statements from the International Maritime Organization or regional authorities signalling corridor safety improvements.

Across platforms, this market reveals structural differences in how books price geopolitical risk. Polymarket's 83% implied probability reflects retail-heavy positioning; Kalshi and Betfair typically show tighter odds on such events, with Kalshi's KYC requirements filtering out speculative retail flow. Fee structures—Polymarket's 2% settlement fee versus Betfair's commission tiering—matter for margin calculations on a market likely to resolve within 24 months, favouring longer-duration traders on lower-fee venues.

Methodology

We read Strait of Hormuz traffic returns to normal by December 31? 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.
