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, making transit volumes a barometer of regional stability and energy markets. The 35% YES price on Polymarket reflects trader scepticism that daily ship arrivals will reach a 7-day moving average of 60 calls by end-July 2026—a threshold that would signal normalisation after recent disruptions. On Polygon, the conditional token structure means YES holders collect USDC only if IMF Portwatch publishes that figure; the market settles immediately upon confirmation rather than waiting for the window close.

Historical precedent matters here. Pre-2024, the Strait regularly saw 70–90 daily transits. The Houthi campaign against shipping, which intensified from October 2023 onwards, depressed flows to the 40–55 range by mid-2024. Recovery has been uneven: some months showed partial rebounds to 55–65, but sustained normalisation proved elusive. The 60-call threshold sits between depressed and historical norms, making it a meaningful but achievable target—hence why the crowd prices it below 40%.

Traders should monitor three variables. First, any escalation or de-escalation in Red Sea attacks, which typically trigger immediate rerouting via the Cape of Good Hope and suppress Hormuz transits. Second, OPEC+ production decisions and geopolitical statements from Iran, Saudi Arabia, or the UAE, which influence shipping demand. Third, IMF Portwatch data releases themselves—the market depends entirely on their methodology and timeliness, with no alternative data source accepted for settlement. Recent reports from shipping indices suggest modest recovery momentum, but sustained 60+ averages remain contingent on sustained regional calm.

Methodology

We track Strait of Hormuz traffic returns to normal by July 31? on the five venues with material liquidity for prediction markets. Live odds come from the Polymarket Polygon order book — the only source that ships real-time data under an open licence. For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.
