The "Before Jul 1, 2026" contract experienced a 33.0 percentage point increase, reaching 54%. This repricing was driven by reports of an emerging US-Iran diplomatic deal, potentially normalizing traffic within 30 days. **Key Market Signals** - **Key Contract Repricing:** The probability for the Strait of Hormuz reopening "Before Jul 1, 2026" surged from 21% to 54%, representing a 33.0 pp increase. - **Near-Term Concentration:** All nine contracts saw probability increases, with the highest trading volume of over 400,000 contracts concentrated in the "Before Jun 1, 2026" contract, shifting the implied normalization timeline into the June-July 2026 period. - **Catalyst for Repricing:** Reports of an imminent US-Iran agreement, including a 60-day ceasefire extension and lifting of the US naval blockade, drove the repricing, with a May 24 report suggesting Strait traffic could return to normal within 30 days. --- The prediction market for the normalization of traffic in the Strait of Hormuz repriced sharply on Saturday, May 23, 2026, as traders reacted to reports of a potential diplomatic breakthrough between the United States and Iran. Probabilities across all nine contracts for an earlier resolution surged, with the market consensus now pointing to a potential reopening within weeks. The "Before Jul 1, 2026" contract saw a significant 33.0 percentage point spike to 54%, reflecting news that an emerging deal could see shipping return to pre-war levels within 30 days [1]. The move represents a dramatic shift from previous expectations of a protracted closure lasting well into 2027 [9]. ## Distribution Analysis The shift was consistent across the entire market, with every available contract seeing a rise in probability. The most significant gains and highest trading volumes were concentrated in the nearest-term outcomes, signaling strong market conviction in a rapid resolution. The largest single move was in the "Before Jul 1, 2026" contract, which jumped from 27% to 60% before settling at 54% on volume exceeding 165,000 contracts. Notably, the "Before Jun 1, 2026" contract saw the highest volume, with over 400,000 contracts traded as its probability climbed 12.0 percentage points. | Outcome | Current Prob | Change | Volume | | :--- | :--- | :--- | :--- | | Before Jun 1, 2026 | 8% | +12.0pp | 400,552 | | Before Jun 15, 2026 | 32% | **+28.0pp** | 136,050 | | Before Jul 1, 2026 | 54% | **+33.0pp** | 165,304 | | Before Aug 1, 2026 | 65% | **+24.0pp** | 76,247 | | Before Sep 1, 2026 | 69% | +20.0pp | 17,935 | | Before Oct 1, 2026 | 72% | +11.0pp | 14,987 | | Before Jan 1, 2027 | 83% | +4.0pp | 22,293 | | Before Apr 1, 2027 | 86% | +3.0pp | 9,806 | | Before Jul 1, 2027 | 88% | +6.0pp | 8,285 | **Net: All 9 eligible contracts rose on total volume of 851,460, sharply pulling the implied timeline for normalization forward into the June-July 2026 period.** ## What's Driving the Shift The significant repricing appears to be a direct response to a series of news reports indicating progress toward a US-Iran agreement to end the regional conflict that began on February 28, 2026. * **Reports of an Imminent Deal:** The primary catalyst was a report on May 24, citing Iran's semi-official Tasnim news agency, that a potential memorandum of understanding would see traffic in the Strait of Hormuz return to pre-war levels within 30 days [1]. The reported deal includes a 60-day ceasefire extension, the lifting of the US naval blockade on Iranian ports, and the reopening of the strait without tolls [1, 2]. US Secretary of State Marco Rubio further fueled optimism by suggesting "good news" could be announced within hours [1]. * **A Market-Wide Reversal:** The move reflects a fundamental shift in market consensus. Prior to these reports, industry analysts and officials from Gulf nations had warned that a full recovery of shipping capacity was unlikely before mid-2027, citing major logistical hurdles including mine clearance, which could take up to six months, and the restoration of maritime insurance coverage [8, 9, 10]. The market's sharp pivot indicates traders believe a political resolution would rapidly overcome these previously priced-in technical obstacles. * **Rising Transit Volumes (Albeit Controlled):** While still far below the normal daily average of over 60 vessels, recent data shows a modest increase in transits. Iranian state media claimed 25 to 35 ships passed through the strait in the 24 hours to May 23 after receiving authorization from Tehran [4, 5]. This controlled increase may provide a baseline of evidence that Iran is capable of scaling up passage quickly if a deal is reached. ## Market Context The Strait of Hormuz has been under severe restrictions since late February 2026, following US-Israeli strikes on Iran and subsequent Iranian retaliation [1]. The de facto closure of a waterway that normally handles 20% of the world’s energy supplies has created significant disruption [3, 10]. Iran has been attempting to formalize a state-administered toll and permit system, further complicating passage for international shipping [3, 4]. Until this weekend, prediction markets and industry forecasts reflected a grim outlook. In April, analysts projected a phased recovery lasting from May to September 2026, with the most expensive and risk-averse vessels like LNG carriers not expected to return to normal traffic levels until the third quarter [8]. The head of the UAE's national oil company, ADNOC, recently warned that full capacity restoration would not occur before the first or second quarter of 2027 [9]. The market’s sudden surge in optimism for a resolution by July 2026 represents a complete break from this earlier, more cautious consensus. ## What to Watch The market's direction will now hinge on official confirmation of the reported deal. Statements from the US State Department or Iran's Supreme National Security Council will be critical. Traders will also be closely monitoring real-time automatic identification system (AIS) shipping data for a sustained increase in vessel transits through the strait, which would serve as the first tangible proof that the waterway is returning to normal operations. The market itself is scheduled to close in July 2027, with settlement based on data from the Statistical Review of World Energy. ## Related Analysis - [Read the complete market report for When will traffic at the Strait of Hormuz return to normal?](/markets/politics/when-will-traffic-at-the-strait-of-hormuz-return-to-normal/) ### Relevant Answer Library - [What's the difference between Polymarket and Kalshi?](/answers/whats-the-difference-between-polymarket-and-kalshi) - [How do fees and platform rules affect prediction market prices?](/answers/how-do-fees-and-platform-rules-affect-prediction-market-prices) - [How do I calculate expected value (EV) for a trade in a prediction market?](/answers/how-do-i-calculate-expected-value-for-a-trade-in-a-prediction-market) - [Browse all Answer Library topics](/answer-library)
