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

Platform comparison

Market context

Commercial shipping through the Strait of Hormuz remains well below normal after the February disruption, with IMF PortWatch’s “Arrivals of Ships” series still the key settlement input. The market needs a 7-day moving average at or above 60 by 30 June, which is close to pre-crisis traffic but far above the latest readings implied by current disruption. That makes the 26% crowd price a view that traffic can rebound sharply within weeks, not merely stabilise at an improved but still depressed level.

Recent comparisons argue for caution on timing. USNI reported on 1 May that commercial transits were at their lowest level since Operation Epic Fury started, with Strait transits below 10% of pre-conflict traffic and tanker and oil markets expected to remain stressed until at least September. IMF PortWatch shows the event as reduced traffic since 28 February, so the market is effectively asking whether a sustained operational recovery can be published before month-end, not whether the geopolitical risk has disappeared. On platforms, Kalshi quotes the same event in implied-probability form, while Polymarket and Betfair usually show decimal pricing that needs conversion; Smarkets uses prices net of commission, so the headline number is not directly comparable after fees. Kalshi also requires KYC and is US-restricted, whereas Betfair and Smarkets have wider European reach, which can affect liquidity and how quickly prices move.

Catalysts are likely to be shipping-security developments, insurance availability, and any signs of Gulf states or naval forces improving convoy confidence. The main practical watchpoint is the IMF PortWatch publication schedule: because settlement turns on a 7-day moving average, a few days of higher counts may matter only if they are sustained and actually reflected in the next data release. Traders should also track whether diverted carriers begin filing again through the strait, since the measure counts reported arrivals across container, dry bulk, ro-ro, general cargo and tankers, not every vessel at sea.

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.
