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 transits, has experienced significant disruption since late 2023 owing to Houthi attacks on commercial shipping and subsequent military interventions. The IMF Portwatch metric tracks daily vessel arrivals across the strait's major ports; a 7-day moving average of 60+ calls would represent a return to pre-disruption baseline traffic levels. Current crowd pricing at 8% implies traders assess this outcome as highly unlikely within the next eighteen months, reflecting persistent regional tensions and the operational complexity of restoring normal shipping patterns once confidence has eroded.

Historical precedent suggests recovery timelines vary sharply depending on threat perception rather than actual incident frequency. The 2019 tanker attacks near the strait depressed traffic for weeks but normalised within months once insurance and security protocols stabilised. The current episode differs: Houthi capability has proven sustained, and no negotiated settlement framework exists. Comparable disruptions—the 2011 Suez Canal closure, the 2022 Russia–Ukraine grain corridor disputes—took 6–12 months to resolve operationally, yet psychological recovery in shipping patterns often lagged resolution by a further quarter. Polymarket's 8% probability aligns with base rates for geopolitical disruptions persisting beyond eighteen months; Kalshi and Smarkets show similar implied probabilities, though decimal-odds presentation on Betfair (roughly 12.5 to 1 against) may frame the tail-risk differently for some traders.

Catalysts centre on Houthi operational tempo, US–Iran diplomatic signals, and shipping-insurance premium adjustments. The UN Houthi monitoring reports (quarterly) and Lloyd's List daily port-call data provide leading indicators; any sustained fortnight without reported incidents typically precedes gradual traffic recovery. Traders should monitor US Central Command statements and insurance market spreads, which currently price elevated risk premiums for Hormuz transits through Q2 2026.

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.
