Short Answer

Strait of Hormuz traffic is not expected to return to normal by August 31, 2026. Daily vessel transits remain severely depressed, far below the 7-day moving average of 60, a view priced at 0.1% by the market.

1. Market Behavior & Drivers

This market's probability has collapsed in response to reports of continued disruption in the Strait of Hormuz. News as of September 1, 2026, confirmed that daily vessel transits remain in the single digits. This is significantly below the 10-day average of approximately 14 vessels and a fraction of pre-war traffic levels. The data points to a persistent state of disruption, directly lowering the perceived likelihood of a return to normal operations by the market's resolution date.
The entire price history has occurred on zero traded volume. The decline from 0.8% to 0.1% reflects adjustments to bids and asks in an inactive order book. While this indicates a negative shift in sentiment, the lack of any traded contracts means the price level has not been established by executed positions.
  • Strait traffic will not normalize by August 31, 2026, due to suppressed volumes.
  • Daily vessel transits remained in single digits through late August 2026.
  • U.S. and Iranian forces maintain opposing positions on navigation freedom.

Current Context

Strait of Hormuz transits remain severely depressed after recent escalation. As of September 1, 2026, daily vessel transits are in the single digits, well below the 10-day average of approximately 14 and far below pre-war levels [1][2][3][4][5]. Military tensions spiked on August 31/September 1, 2026, involving exchanges of fire between U.S. and Iranian forces [6][7]. Reports indicate multiple tankers were hit by projectiles or naval mines, further destabilizing the waterway [6][8][9][10]. This follows the lapse of a 60-day memorandum of understanding on August 17, 2026, and subsequent escalation by the U.S. government, leading to an effective closure of the Strait [11].
Market analysts expect disruptions to persist well into 2027. They warn the Strait may face a protracted "no war, no peace" situation, with only partial volumes flowing that could extend into 2027 [12]. The U.S. Energy Information Administration (EIA) assumes severe constraints on transits will persist through August 2026, with only slow, limited increases in shipping flows expected in September 2026 [13]. The EIA forecasts a return to pre-conflict status for production and trade patterns in the region will likely take until early 2027, with persistent disruptions of approximately 0.6 million barrels per day expected through the end of 2027 [13]. Current shipments from the Persian Gulf are approximately two-thirds of pre-war volumes [14].

3. Market Data

Contract Snapshot

This market resolves to "Yes" if IMF Portwatch publishes a 7-day moving average of transit calls for the Strait of Hormuz (including container, dry bulk, roll-on/roll-off, general cargo, and tanker ships) equal to or above 60 for any date between market creation and August 31, 2026; otherwise, it resolves "No."

The official data source is IMF Portwatch (portwatch.imf.org), with resolution occurring as soon as the condition is met, or based on data published up to 14 calendar days after August 31, 2026, if final data is delayed. Revisions to previously published data points made within the market's timeframe will be considered, but revisions after August 31, 2026, will not. Obvious data integrity issues may keep the market open for up to three calendar days for corrections.

Market Discussion

The market discussion indicates that commercial traffic through the Strait of Hormuz remains significantly suppressed, far below pre-crisis averages (e.g., 5 daily transits compared to 130-140 normally). Arguments against traffic returning to normal by August 31, 2026, cite persistent security threats, renewed attacks on carriers, lingering mines, GNSS interference, high war-risk premiums, and insurer pullbacks, which currently keep flows at near-zero. Potential catalysts for a "Yes" resolution include U.S.-Iran diplomatic progress on traffic administration, mine-clearance verification, or further kinetic incidents that could shift insurance pricing and operator willingness, though the market's <1% price for "Yes" suggests a strong consensus against this outcome.

5. What does recent maritime tracking data from sources like the EIA and IMF PortWatch reveal about daily vessel transit volumes through the Strait of Hormuz in August 2026 compared to pre-conflict averages?

Daily Commercial Vessel Transits4% of pre-crisis volumes (late August 2026) [1][2]
Vessels per day3-4 vessels per day (late August 2026) compared to 85 pre-conflict [1][2]
Total Oil Flows7-8 million barrels per day (late August 2026) compared to 20-21 million pre-conflict [3][4]
Strait of Hormuz vessel transits remain severely depressed in August 2026. As of late August 2026, daily commercial vessel transits through the Strait of Hormuz were approximately 4% of pre-crisis volumes [1][2]. This represents roughly 3–4 vessels per day, a considerable drop from the pre-conflict baseline of about 85 vessels daily [1][2]. The accuracy of maritime tracking data is complicated by some vessels operating with AIS transponders switched off, suggesting official transit figures may be suppressed by both physical blockade and strategic operational choices [1][2][5].
Oil flows through the Strait are significantly reduced despite workarounds. Total oil flows through the Strait were estimated at 7–8 million barrels per day in late August 2026, well below the pre-conflict average of approximately 20–21 million barrels per day [3][4]. This reduced flow persists despite the adoption of workarounds like ship-to-ship transfers and the use of smaller shuttle tankers [3][4]. Prediction markets as of late August 2026 assigned a low probability, approximately 34%, to the likelihood of Strait of Hormuz traffic returning to normal levels by December 31, 2026 [4].

6. What are the official positions of Iran's IRGC Navy and the U.S. Fifth Fleet regarding freedom of navigation in the Strait following the August 2026 escalation?

IRGC Navy Strait StatusClosed to vessels without Iranian approval (late August 2026) [1][2]
U.S. Stance on StraitInternational waterway, freedom of navigation required [2][3][4][5]
Strait Normalization Probability5.5% by September 30, 2026 (late August) [6][7][8]
Iranian and U.S. forces hold opposing views on Strait of Hormuz navigation. As of late August 2026, the Islamic Revolutionary Guard Corps (IRGC) Navy asserts the Strait of Hormuz is effectively closed to all vessels without prior coordination and approval from Iranian authorities, claiming full and decisive control over the waterway. These restrictions are stated to continue until U.S. military "aggression" against Iran ends [1][2]. Conversely, the U.S. Fifth Fleet and broader U.S. policy reject Iran's claims of jurisdiction, maintaining that the Strait of Hormuz is an international waterway where commercial shipping must enjoy freedom of navigation [2][3][4][5].
Commercial traffic in the Strait of Hormuz has dramatically decreased. This situation has led to significantly reduced commercial traffic through the Strait, operating at a small fraction of its pre-crisis volumes, despite ongoing high-risk conditions and reports of U.S. military-escorted transits [2][3][4][5][9]. Many countries are now relying on workarounds like ship-to-ship transfers outside the Strait or pipelines to avoid the high-risk transit zone [9][6][7][8]. Prediction market participants remain highly skeptical of a return to normal traffic conditions, with the probability of normalization by September 30, 2026, dropping to roughly 5.5% as of late August [6][7][8].

7. How do the primary overland oil pipeline alternatives, such as Saudi Arabia's East-West Pipeline, compare to the Strait of Hormuz in terms of daily capacity, cost per barrel, and vulnerability?

Normal Strait of Hormuz Capacity20 million bpd [1][2][3][4]
Combined Bypass Pipeline Capacity9 million bpd [1][2][3][4]
Strait of Hormuz Blocked SinceFebruary 2026 [1][2][5]
The Strait of Hormuz blockage reveals significant capacity shortfalls in alternatives. Since February 2026, ongoing conflict has blocked or restricted the Strait of Hormuz, a critical waterway that typically handles approximately 20 million barrels of oil and petroleum products per day [1][2][5][6][7]. This situation has necessitated reliance on primary overland oil pipeline alternatives, such as Saudi Arabia's East-West Pipeline [1][2][5][6][7]. However, the combined operational capacity of all available bypass pipelines is considerably less, managing only about 9 million barrels per day [1][2][3][4].
Alternative overland pipelines pose higher costs and persistent security risks. Transporting oil via these bypass routes, whether by pipeline or trucking, is substantially more expensive than traditional tanker transit through the Strait of Hormuz, with rerouting around the Cape of Good Hope alone adding hundreds of thousands of dollars to individual voyages [3][8]. While these overland alternatives are crucial as relief valves, they do not fully replace the Strait of Hormuz, instead functioning more as a geopolitical hedge [8][5]. Like other oil infrastructure, pipelines remain susceptible to low-cost, asymmetric attacks, such as drones or strikes, which makes them vulnerable to disruption [8][5]. The current blockage of the Strait of Hormuz underscores the strategic importance of understanding these limitations and vulnerabilities of alternative routes, a concern that has historically driven geopolitical focus on the Strait's potential for disruption [9].

8. What are the most reliable public sources for tracking daily and weekly commodity vessel transits through the Strait of Hormuz for the latter half of 2026?

Commercial Transit Levels (Sep 1, 2026)Approximately 4% of pre-crisis baselines [1]
Strait of Hormuz Status (Sep 1, 2026)Contested [1]
Key Tracking FocusIdentifying 'dark' transits and anchored vessel queues [2][3][1]
Tracking daily and weekly commodity vessel transits through the Strait of Hormuz in the latter half of 2026 necessitates specialized maritime intelligence platforms and broader data aggregators [4][1]. This is particularly crucial because commercial transit levels, as of September 1, 2026, were reported at roughly 4% of pre-crisis baselines, indicating a significantly reduced flow [1].
Specialized platforms and aggregators offer diverse vessel transit tracking. Specialized platforms offer detailed insights into vessel movements, with examples including Windward providing daily intelligence and dark transit detection [4], and Straits.live offering a live tracker and comprehensive transit data [1]. Broader data aggregators, such as IMF PortWatch, supply periodic updates on chokepoint activity [4]. Advanced tracking methodologies also prioritize identifying 'dark' transits, involving AIS-disabled vessels, and monitoring anchored vessel queues at key waiting areas like Kharg Island, as these are critical indicators of transit friction and potential closure risks [2][3][1].
Contested Strait conditions limit commercial transits, affecting predictions. As of September 1, 2026, the Strait of Hormuz remained contested, directly impacting maritime traffic [1]. Commercial transit levels during this period were reported at approximately 4% of pre-crisis baselines [1]. Consequently, the resolution of prediction markets concerning a return to 'normal' traffic is highly dependent on establishing specific definitions for what constitutes a normalized flow [1].

9. What specific diplomatic or military events involving the U.S. and Iran could trigger a return to pre-conflict shipping levels in the Strait of Hormuz before Q4 2026?

Shipping Normalization OutlookUnlikely before Q4 2026 [1][2][3][4]
US-Iran Diplomacy StatusStalled, no active negotiations [2][5][6][7]
Strait of Hormuz Military StatusUS naval blockade in effect [6]
A return to normal shipping levels before Q4 2026 is widely considered improbable. Prediction markets indicate a high probability that traffic in the Strait of Hormuz will not normalize within 2026 [1][2][3][4]. A significant factor contributing to this unlikelihood is the absence of a comprehensive diplomatic deal, which is viewed as a necessary diplomatic trigger for normalization [1][2][3][4]. Currently, diplomacy between the U.S. and Iran has stalled, with no active negotiations taking place [2][5][6][7].
However, specific diplomatic and military actions could prompt normalization. Iran has conditioned a temporary shipping corridor agreement, exclusively with Oman, on the U.S. lifting its naval blockade, removing sanctions, and reverting to the terms of the failed mid-June Memorandum of Understanding (MOU) [2][5][6][7]. The Strait of Hormuz is effectively under a U.S. naval blockade [6], making the lifting of this blockade a crucial military event. Conversely, persistent military escalation is cited as an impediment to normalization, suggesting that a cessation of such escalation would be a necessary military development [1][2][3][4].

10. What Could Change the Odds

Key Catalysts

The Strait of Hormuz is effectively closed to most commercial traffic, with daily transits hovering around 5 ships as of September 1, 2026, significantly below the pre-war average of 130-140 ships [1][2][3][4][5]. This disruption began on February 28, 2026, following U.S.-Israeli military operations against Iran, which led to persistent Iranian threats, attacks on tankers, elevated war-risk insurance costs, and depressed commercial activity [4][6][7][8]. The Strait's status as effectively closed or severely constrained as of September 1, 2026, followed the expiration of a 60-day memorandum on August 17, 2026, and subsequent escalation in economic sanctions by the United States [9][10][11].
Prediction markets, including Polymarket and Manifold, overwhelmingly reflect low expectations for a return to normal traffic in 2026, with implied probabilities for a 'No Return to Normal' outcome often exceeding 70-80% [12][13][14][15]. As of early September 2026, market-implied sentiment indicates no anticipation of a significant or normal recovery in transit traffic in the immediate short term [16][17]. The U.S. Energy Information Administration (EIA) forecasts only a gradual increase in shipping traffic through the Strait throughout September 2026, with a return to pre-conflict trade and production patterns not expected until early 2027 [10][11].
Diplomatic efforts, led by Qatar and Pakistan, are ongoing to negotiate conditions for reopening the Strait [8]. However, these efforts are hampered by disagreements between Iran and the U.S. and the ongoing economic pressure campaign [8]. Iran says it reached an agreement with Oman on a proposed shipping [18]. Pakistan states a deal is close even as Iran and the U.S. harden stances [19], while Iran dismisses U.S. threats of economic pain and isolation [20].
