Will 2026 ships transit the Strait of Hormuz on any day by July 31?

Platform comparison

Market context

Ships crossing the Strait of Hormuz, the world’s most critical energy chokepoint, face a 46% crowd-implied chance of hitting a listed transit threshold by July 2026. Over 30,000 vessels pass annually, including tankers, dry bulk, and container ships, yet daily crossings have collapsed by more than 95% since the Iran war began, according to recent IMF PortWatch data[6]. Historically, the strait averaged 75–125 crossings per day before the conflict, but current flows remain severely depressed, framing the current probability as a bet on partial recovery rather than a return to pre-war volumes[6].

Traders should monitor official announcements from Iran and regional powers, scheduled port inspections, and any shifts in Red Sea shipping routes that could redirect traffic toward Hormuz. Recent disruptions in the Red Sea, documented by IMF PortWatch, have already raised concerns about rerouted tanker flows affecting Hormuz volumes[7]. Platforms diverge sharply here: Polymarket offers decimal odds with low fees and no KYC, while Kalshi and Betfair require identity verification and charge higher fees but provide regulatory oversight. Smarkets and Kalshi also differ in how they present implied probability versus decimal pricing, which can alter how traders interpret the 46% YES signal on this specific market.

The settlement window closes on 31 July 2026, with data only considered once finalized by the next day’s IMF PortWatch update[5]. Until geopolitical tensions ease or new shipping corridors open, the strait’s transit numbers will likely remain volatile, making this market a high-stakes indicator of global energy logistics resilience.
