| Above 30 | 43.0% | 45.2% | Traffic through the Strait of Hormuz is expected to remain severely depressed. |
| Above 35 | 27.0% | 27.0% | Traffic through the Strait of Hormuz is expected to remain severely depressed. |
| Above 25 | 76.0% | 73.6% | Traffic through the Strait of Hormuz is expected to remain severely depressed. |
| Above 40 | 12.0% | 16.0% | Traffic through the Strait of Hormuz is expected to remain severely depressed. |
| Above 45 | 14.0% | 9.4% | Traffic through the Strait of Hormuz is expected to remain severely depressed. |
Current Context
Commercial traffic through the Strait of Hormuz remains severely restricted. Between August 24 and August 26, 2026, commercial transits hovered at record lows, often fewer than 5-20 vessels per day [^][^][^][^][^]. This volume significantly trails the 10-day average of approximately 15 transits and is roughly 90% below pre-conflict baselines [^][^][^][^][^]. This persistent reduction follows renewed U.S. naval blockades and Iranian attacks in July 2026, which had previously decreased cross-Strait traffic [^][^]. A June 17, 2026, memorandum of understanding between the U.S. and Iran, intended to facilitate safe passage, was invalidated by President Trump in mid-July 2026 after repeated Iranian attacks on ships off Oman [^][^].
Diplomatic efforts to reopen the Strait face ongoing geopolitical deadlock. As of August 26, 2026, Iran and Oman are negotiating a phased framework for a temporary joint maritime corridor and a joint mine-clearing project to restore navigation [^][^][^][^]. However, Iran maintains the waterway is officially closed and subject to its surveillance and approval [^][^]. Broader tensions remain deadlocked. The U.S. has reportedly offered to lift sanctions and end its naval blockade in exchange for guaranteed free passage [^]. Iran continues to demand massive compensation, total sanctions relief, and regional troop withdrawals [^][^][^].
Energy markets adapted to the blockade through alternative transfer methods. Energy markets have adjusted to the ongoing blockade through ship-to-ship transfers in the Gulf of Oman and by using shuttle voyages [^][^][^]. These measures continue despite the ongoing risk to commercial vessels and the thousands of stranded seafarers [^][^][^][^].
2. Market Behavior & Price Dynamics
Historical Price (Probability)
Outcome probability
Date
The contract predicting traffic levels through the Strait of Hormuz has been defined by high volatility and a sharp upward repricing from its initial 3.0% probability. The market traded in a wide range, between 3.0% and 75.0%, before settling at its current level of 43.0%. The price action has been event-driven, reacting sharply to news flow concerning negotiations and official statements. The market experienced several significant price swings, including a 23.0 percentage point spike on August 21 and a subsequent 22.0 point spike on August 23. This latter move was likely driven by speculative optimism regarding talks between Iran and Oman for a temporary maritime corridor.
The market's bullish trend reversed mid-week. After reaching a peak of 55.0% on August 25, the probability fell. A key driver for this downturn was the August 26 announcement by Iranian authorities that the strait remained closed, which pushed the contract down 9.0 percentage points to 43.0%. This price action suggests that initial optimism about a diplomatic resolution has been tempered by official statements and reports of continued low transit volumes, with commercial traffic reported at fewer than 20 vessels per day over the August 24-26 period. Volume data indicates market participation increased alongside the volatility, with trading activity picking up around the most recent price drop, suggesting greater conviction behind the move. The market appears to be pricing in a sustained period of disruption.
3. Significant Price Movements
Notable price changes detected in the chart, along with research into what caused each movement.
Outcome: Above 30
📉 August 26, 2026: 9.0pp drop
Price decreased from 52.0% to 43.0%
What happened: On August 26, 2026, the primary driver for the 9.0 percentage point drop in the "Above 30" outcome was the announcement by Iranian authorities that the Strait of Hormuz remained effectively closed, despite ongoing negotiations for a temporary maritime corridor with Oman [^][^][^]. This statement, reported across major news outlets, directly reinforced the expectation of continued severely reduced commercial vessel traffic, which had been at single-digit or low-teen daily levels throughout mid-to-late August [^][^]. The news coincided directly with the market movement, causing a significant decline in confidence that traffic would surpass 30 vessels. Social media was not a primary driver in this specific market movement.
📈 August 23, 2026: 22.0pp spike
Price increased from 26.0% to 48.0%
What happened: The 22.0 percentage point spike in the prediction market on August 23, 2026, likely stemmed from speculative optimism surrounding perceived progress in the "ongoing Iran-Oman talks" regarding a "temporary joint maritime corridor" [^][^][^][^]. While specific social media posts or breaking news on that exact date are not provided, an unconfirmed report or rumor of an imminent agreement may have circulated, temporarily boosting expectations of traffic rising "Above 30" for the August 24-30 period [^]. However, this proved premature, as actual traffic remained severely suppressed, and Iranian officials explicitly stated the strait was still closed [^][^]. Given the lack of specific, dated social media evidence, its role was likely an unconfirmed accelerant for unverified rumors, rather than a primary driver based on concrete statements.
Outcome: Above 45
📉 August 25, 2026: 79.0pp drop
Price decreased from 86.0% to 7.0%
What happened: The primary driver of the 79.0 percentage point drop for the "Above 45" outcome on August 25, 2026, was a series of traditional news reports indicating severely restricted traffic through the Strait of Hormuz. On August 24, 2026, Iran announced it had blacklisted 45 tankers and imposed new transit rules, threatening fines and cargo confiscation [^][^]. This official action was immediately followed by reports on August 25, 2026, confirming that direct vessel traffic was approximately 90% below pre-conflict levels, with only five commodity vessels transiting that day [^][^][^][^]. These developments directly contradicted the market's "Above 45" outcome, causing the significant price adjustment. Social media activity was not identified as a primary driver, contributing accelerant, or significant noise based on the provided information.
📈 August 24, 2026: 74.0pp spike
Price increased from 12.0% to 86.0%
What happened: The prediction market price spike for "Above 45" traffic in the Strait of Hormuz was primarily driven by traditional news reports around August 25-26, 2026, which indicated Iran and Oman had outlined a plan or reached an agreement for a temporary shipping corridor [^][^]. This news likely created an expectation among market participants for increased vessel transits, despite Iran simultaneously maintaining the waterway remained blockaded [^]. However, actual shipping traffic during this period remained at multi-month lows, with no evidence of a corresponding spike in vessel transits [^][^][^]. Social media activity was not identified as a primary driver.
Outcome: Above 25
📈 August 22, 2026: 13.0pp spike
Price increased from 45.0% to 58.0%
What happened: The 13.0 percentage point spike on August 22, 2026, was primarily driven by traditional news reports. Specifically, the New York Post published an article that day titled "Traffic through Strait of Hormuz skyrockets nearly 400%" [^], which directly suggested a significant increase in vessel transits. This coincided with news from Bloomberg reporting that an agreement between Iran and Oman on proposed shipping lanes was in its final stages [^], further contributing to expectations of higher traffic. Social media activity was not a primary driver.

6. What specific outcomes from the ongoing Iran-Oman negotiations could alter vessel traffic through the Strait of Hormuz before August 30?
| Joint Corridor/Mine-Clearing Project | August 25-26, 2026 [^][^][^][^] |
|---|---|
| Current Daily Vessel Traffic | 10-15 vessels daily [^][^][^][^] |
| Prediction Market Traffic (late Aug 2026) | 0-20 vessels per day [^][^] |
Iran and Oman agreed to a temporary Strait of Hormuz corridor. Iran and Oman have announced a framework for a "joint temporary navigational corridor" through the Strait of Hormuz, alongside a joint mine-clearing project scheduled for August 25-26, 2026 [^][^][^][^]. They also reached an agreement on a proposed shipping route [^]. Despite these agreements, the Strait remains effectively blockaded, as Iranian officials maintain it will not reopen until the United States fulfills commitments from a June memorandum of understanding [^]. The proposed temporary route dictates that inbound vessel traffic would pass entirely through Iranian waters, while outbound traffic would transit through both Iranian and Omani waters; however, its implementation details and U.S. acceptance remain uncertain [^][^][^].
Vessel traffic remains suppressed despite the announced framework. Despite the announced framework, commercial vessel traffic through the Strait of Hormuz remains severely suppressed, currently averaging only 10-15 vessels daily, which represents a small fraction of pre-conflict volumes [^][^][^][^]. An Iranian blacklist of 45 ships and ongoing geopolitical risks continue to deter commercial shipping operations [^][^][^][^]. Prediction markets tracking Strait of Hormuz traffic for late August 2026 overwhelmingly favor low-volume outcomes of 0-20 vessels per day, reflecting a market consensus that the current framework will not significantly increase traffic before August 30 [^][^].
7. What does recent satellite and AIS tracking data from August 2026 indicate about daily transit volume in the Strait of Hormuz compared to pre-conflict levels?
| Current Daily Transit Volume | Single-digit or low-teen vessels (late August 2026) [^][^][^][^] |
|---|---|
| Decline from Pre-conflict Baseline | Approximately 90% (compared to 70–130+ vessels/day) [^][^][^][^] |
| Prediction Market Weekly Calls | 70-75%+ probability of 25–49 calls (week of August 24–30, 2026) [^][^][^] |
Daily transit volume in the Strait of Hormuz has significantly decreased by August 2026. As of late August 2026, daily transit volume through the Strait of Hormuz has dramatically decreased to single-digit or low-teen numbers of vessels [^][^][^][^]. This represents an approximate 90% decline from pre-conflict levels, which saw 70–130+ vessels per day [^][^][^][^]. While raw transit counts might appear somewhat stable, this is primarily due to an increase in empty or sanctioned vessels, with laden commercial transit volumes remaining severely suppressed [^][^][^].
High-risk conditions obscure accurate real-time transit metrics. Dual blockades by the U.S. and Iran have created high-risk conditions, prompting many operators to use 'dark' routes where AIS is disabled, thus complicating the accuracy of real-time transit metrics [^][^][^][^]. Prediction markets for the week of August 24–30, 2026, indicate a high confidence of 70-75%+ that total weekly transit calls will remain in the low 25–49 range [^][^][^]. The industry continues to await a resolution to reopen the Strait of Hormuz [^].
8. How do the current negotiating positions of the United States and Iran regarding sanctions relief and freedom of navigation compare as of late August 2026?
| US Proposal Condition | Reopening Strait of Hormuz and halting proxy attacks (late August 2026) [^][^][^] |
|---|---|
| Iran's Demands | War reparations, full lifting of US sanctions, total US withdrawal [^][^][^] |
| Strait of Hormuz Normal Traffic Prediction | Low single digits for 'Yes' by August 31, 2026 [^][^] |
US and Iran remain at odds over sanctions and the Strait. As of late August 2026, the United States has reportedly proposed lifting economic sanctions and its naval blockade against Iran in exchange for Tehran reopening the Strait of Hormuz and halting attacks by regional proxies [^][^][^]. Iran, however, rejects these offers, maintaining that the Strait of Hormuz is closed and demanding comprehensive war reparations, the full lifting of all US sanctions, and a total withdrawal of US forces from the region before any full reopening [^][^][^]. While Iran and Oman have agreed on a temporary 7-mile transit corridor in the Strait of Hormuz, Iranian officials have emphasized that this is not a full reopening [^][^].
Prospects for a full resolution by late August 2026 appear dim. Prediction markets show significant pessimism regarding a return to normal traffic levels in the Strait of Hormuz by August 31, 2026, with implied probabilities for 'Yes' outcomes frequently cited in the low single digits [^][^]. Reports indicate that US-Iran peace prospects are dimming, and President Trump is reportedly in no hurry for a deal [^]. Despite this, Pakistan's defense minister has stated that the US and Iran are close to some sort of arrangement over the strait [^].
9. Which maritime analytics platforms are providing reliable, near-real-time data on vessel transits through the Strait of Hormuz for the August 24-30 period?
| Daily Vessel Crossings (August 23, 2026) | 3 vessels [^] |
|---|---|
| Pre-crisis Baseline Percentage | Approximately 4% [^] |
| Polymarket 'No' Outcome Probability | Over 98% [^] |
Transit volumes through the Strait of Hormuz remained severely depressed around August 24-30, 2026. Several maritime analytics platforms and independent monitors offer reliable, near-real-time data on vessel transits. These include SeaVantage [^], Strait Up Maritime [^], Straits.live [^], StockDrifts [^], Hormuzmonitor.com [^], and Hormuzstraitmonitor.com [^], along with the GitHub-hosted oliv3561/hormuz-tracker [^]. These platforms typically utilize Automatic Identification System (AIS) data, often enhanced with Synthetic Aperture Radar (SAR) detections to track 'dark' ships and provide comprehensive transit intelligence [^][^][^][^][^][^][^].
Only three vessels crossed the Strait of Hormuz on August 23, 2026. This figure represents approximately 4% of the normal pre-crisis baseline daily vessel crossings [^]. Regarding the prospect of traffic returning to normal levels by August 31, 2026, the Polymarket prediction heavily favors a 'No' outcome, indicating an over 98% probability for that resolution [^].
10. What evidence from energy markets indicates how commercial operators like Maersk and Euronav are adapting to the Strait of Hormuz blockade?
| Date of Low Traffic | August 26, 2026 [^][^][^][^][^] |
|---|---|
| Daily Vessel Transits | Single digits [^][^][^][^][^] |
| Traffic Level | Multi-month low [^][^][^][^][^] |
Strait of Hormuz maritime traffic has significantly declined since August 2026. As of August 26, 2026, daily vessel transits have fallen to a multi-month low, frequently in the single digits [^][^][^][^][^]. This significant reduction from pre-war levels is attributed to a US-led naval blockade, ongoing retaliatory attacks targeting commercial vessels, and the expiration of a short-lived June US-Iran interim shipping agreement [^][^][^][^][^].
Commercial operators are implementing diverse strategies to adapt to Strait challenges. To navigate the prevalent challenges and avoid the Strait's most contested areas, commercial operators are deploying various adaptive measures [^][^]. These include prioritizing ship-to-ship (STS) transfers in the Gulf of Oman, utilizing "dark transits" where AIS is intentionally turned off, and re-routing cargo [^][^]. Specifically, major carriers are diverting shipments to alternative terminals in the UAE, such as Fujairah, and ports along Saudi Arabia's Red Sea coast [^][^].
11. What Could Change the Odds
Key Catalysts
The Strait of Hormuz remains in a state of severe, ongoing disruption due to the conflict between the U.S./Israel and Iran, which began in February 2026 [^] [^] [^] . Conflict with Iran" data-source-lanes="curated">[^]. Commercial shipping has effectively halted for much of the conflict, with Iran reportedly continuing to facilitate passage for some of its own oil exports [^][^]. For the week of August 24–30, 2026, traffic hit a three-month low, with daily transits often under 10 vessels. This is significantly below the 10-day average of approximately 14–15 vessels and far from pre-war baselines of 88–130 vessels [^][^][^].
On August 25, 2026, Iran and Oman discussed a proposed framework for an interim transit corridor and a joint mine-clearing project [^] [^] . However, analysts remain skeptical that this will lead to full normalization without broader U.S.-Iran diplomatic concessions, such as the lifting of naval blockades and sanctions [^][^]. Prediction markets, including Polymarket, reflect this skepticism, with implied probabilities for a return to normal shipping traffic by August 31, 2026, consistently below 5% in late August. Expectations for resolution by November 30, 2026, are also low, at approximately 28% 'Yes' [^][^][^][^].
Bullish factors for energy prices include the persistent 'Hormuz risk premium' due to the ongoing naval blockade and sporadic hostilities [^] [^] [^] . Conversely, bearish catalysts for prices, distinct from normalization, include expanded ship-to-ship transfers outside the Strait and attempts to establish interim corridors [^][^][^]. The United States has implemented policy responses, including a Jones Act waiver for domestic coastal shipping, extended through August 16, 2026, to mitigate the impact of supply disruptions on commodities [^][^].
