What is happening now
The Strait of Hormuz, a critical chokepoint for global oil shipments, has seen a dramatic decline in transit activity since February 2026, when Iran’s Revolutionary Guard Corps (IRGC) imposed restrictions following geopolitical tensions. As of June 23, 2026, the market reflects a 96% probability that at least 80 ships will transit the strait on any day by June 30, 2026, while the probability of 20+ ships transiting is 99.6%. However, the 40+ ships market shows a 54.5% chance of “No,” indicating uncertainty about whether transit volumes will reach 40 ships on any single day. This divergence suggests traders expect a partial recovery but not a return to pre-crisis levels.
Iran has conditionally offered to reopen the strait if the U.S. lifts its port blockade, which expired on May 29, 2026. However, no formal agreement has been finalized, leaving the strait’s status in flux. The IRGC’s enforcement of sea mines and vessel inspections continues to deter commercial traffic, though some analysts suggest a potential diplomatic breakthrough could alter the market’s trajectory.
How the market is structured
This is a threshold ladder market with four outcomes: 20+, 40+, 60+, and 80+ ships transiting the strait on any day by June 30, 2026. Each market resolves to “Yes” if the IMF Portwatch reports a daily transit count meeting or exceeding the threshold. The structure allows traders to bet on specific ranges, with higher thresholds (e.g., 80+) having lower probabilities due to their stricter criteria.
Key details:
- 20+ ships: 99.6% probability of “Yes” (price: $0.996).
- 40+ ships: 54.5% probability of “No” (price: $0.545).
- 60+ ships: 83.5% probability of “No” (price: $0.835).
- 80+ ships: 96% probability of “Yes” (price: $0.96).
The market’s design emphasizes the likelihood of partial recovery, with the 20+ threshold being the most certain outcome.
Path to the leading outcome
The leading outcome for the 80+ ships market (“Yes” at 96%) hinges on a sustained increase in transit volumes. This would require:
- Iran’s conditional reopening: If Iran formally lifts restrictions and allows unrestricted commercial navigation, as outlined in its May 2026 offer, transit volumes could rebound.
- U.S.-Iran diplomatic progress: A formal agreement to remove the U.S. port blockade or establish a neutral transit framework would reduce uncertainty.
- Operational normalization: Iranian authorities clearing sea mines and easing inspections to restore pre-crisis traffic levels.
Traders betting on “Yes” for 80+ ships likely anticipate these factors aligning before June 30, 2026.
What could change the pricing
Several events could shift the market away from the current leader:
- Failure to reopen: If Iran refuses to lift restrictions or the U.S. maintains the blockade, transit volumes may remain below 20 ships, triggering a “No” resolution for all thresholds.
- Partial reopening: A limited agreement allowing only specific vessel types (e.g., tankers) could push the 20+ threshold to “Yes” but keep 40+ and higher thresholds at “No.”
- Data discrepancies: If IMF Portwatch reports conflicting or delayed data, the market could remain open until resolution mechanics (e.g., third-day corrections) clarify the outcome.
- Geopolitical escalation
: Further Iranian military actions or U.S. sanctions could exacerbate the closure, lowering probabilities for all thresholds.
Market participants must monitor real-time data from IMF Portwatch and diplomatic developments to assess these risks.
Editorial read
The current market structure reflects a high degree of uncertainty about the Strait of Hormuz’s future. While the 20+ ships threshold is nearly certain to resolve “Yes,” the 40+ and higher thresholds remain contested. This suggests traders expect a modest recovery but not a full return to pre-crisis levels. The 80+ market’s 96% probability indicates optimism about partial reopening, but the 40+ market’s 54.5% “No” price highlights skepticism about reaching that threshold. With $1.8 million in trading volume and $138 million in liquidity, the market is actively tracking developments, though resolution mechanics (e.g., data finalization timelines) could introduce volatility. Investors should focus on Iran’s conditional offer and U.S. policy shifts, as these are the primary drivers of the market’s direction.
