Market context
Ships are moving in and out of the Persian Gulf again, easing oil prices after weekend attacks temporarily disrupted the Strait of Hormuz. On the weekend of 6 July 2026, 29 vessels passed on Saturday and only 12 on Sunday, a sharp drop from the 74 ships recorded the previous Wednesday [4]. By 6 July, traffic had begun recovering over the weekend, though passages remained below normal levels [3]. This volatility frames the current 82% YES probability: while the choke point is open, the settlement window captures a week where disruptions recently slashed daily counts by more than half.
Historically, Hormuz transits average 40–50 ships per day under stable conditions, but geopolitical shocks can halve that volume within hours. The June 2026 bottleneck saw zero outbound commercial vessels for 72 hours, underscoring how quickly traffic can collapse [2]. Conversely, the US-Iran deal signed in mid-June resumed tanker flows, with 40 ships passing on a single Monday shortly after [5][6]. The 82% market price likely assumes the recovery trend continues, but the recent weekend dip suggests the total for 6–12 July could fall short of typical weekly averages if further attacks occur.
Traders must watch for announcements from Iran, US-Iran ceasefire updates, and real-time data from Kpler or MarineTraffic, which track daily transits [4][9]. The market resolves on IMF Portwatch’s finalized transit calls, which only count once the next day’s data point arrives [1]. On Polymarket, this contract trades in USDC on Polygon using conditional tokens, where the 82% price reflects crowd confidence in uninterrupted flows despite the recent volatility. Any new weekend attacks or diplomatic setbacks could rapidly shift the probability as the settlement window closes on 12 July.
