Strait of Hormuz traffic returns to normal by July 31?

Platform comparison

Market context

The Strait of Hormuz handles roughly one-third of global seaborne oil trade, with daily transit volumes typically ranging between 60 and 80 vessel arrivals. The market resolves affirmatively if the IMF Portwatch 7-day moving average of transit calls reaches 60 or higher at any point before 31 July 2026. Current crowd probability of 48% reflects genuine uncertainty about whether regional tensions, geopolitical incidents, or infrastructure disruptions will suppress traffic below that threshold over the next 18 months.

Historical precedent matters here. During the 2022 Houthi escalation and subsequent Red Sea diversions, Hormuz traffic remained resilient because alternative routes (around the Cape of Good Hope) proved economically unviable for most operators. The 2019 tanker attacks saw temporary spikes in insurance costs but no sustained traffic collapse. A 7-day average of 60 represents a modest baseline—roughly 75% of pre-disruption norms—suggesting the market is pricing in moderate, not catastrophic, supply-chain friction. Traders comparing odds across platforms should note that Polymarket's fee structure (2% maker, 2% taker) differs materially from Kalshi's flat-fee model, affecting position sizing calculations on lower-probability outcomes.

Catalysts to monitor include Iranian nuclear negotiations, Houthi weapons capability announcements, and any declared US naval posture shifts in the Gulf. The IMF Portwatch data publication schedule is weekly; traders should verify the exact release timing on the IMF website to avoid settlement ambiguity. Betfair and Smarkets typically offer decimal odds formats on this class of geopolitical market, whereas Polymarket displays implied probabilities directly—a distinction that affects how traders interpret the current 48% reading relative to their own risk assessments.

Methodology

We read Strait of Hormuz traffic returns to normal by July 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

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). Polymarket Alternative routes every trade directly into Polymarket's on-chain settlement, which is why payouts land fastest.
