Current Context
Traffic through the Strait of Hormuz remains severely restricted since February 28, 2026. The waterway has been largely closed or severely restricted since February 28, 2026, following a conflict involving US-Israeli strikes on Iran and Iran's subsequent retaliation and attempts to assert control over the waterway [^][^][^][^][^]. Real-time data shows significantly reduced traffic, with only 11 transits recorded in the past 24 hours, compared to a normal daily average of 60 vessels [^]. At times, as few as a single container vessel has been observed moving through the choke point [^]. Outbound commercial maritime traffic has experienced critical bottlenecks, with zero completed outbound transits recorded on certain days [^]. Major shipping carriers have responded by suspending transits and rerouting vessels primarily via the Cape of Good Hope, which adds considerable time and cost to voyages [^][^].
The ongoing disruption stems from the 2026 Iran war and Iran's assertive control. The conflict began with US-Israeli airstrikes on Iran and the killing of Iran's supreme leader on February 28, 2026 [^][^][^]. Iran responded by launching missile and drone attacks and has actively blocked the strait, issuing warnings and attacking merchant ships [^]. A key development is Iran's establishment of a new "Persian Gulf Strait Authority (PGSA)," which is attempting to formalize Iranian control over the strait by requiring vessels to submit applications and potentially pay tolls for passage [^][^][^][^]. This move is seen as defying international maritime law [^][^]. Diplomatic efforts are underway, with Pakistan mediating peace talks between the United States and Iran [^]. While President Trump has paused a US Navy escort operation ("Project Freedom") citing progress, he has also threatened escalated military strikes if Iran rejects US proposals [^][^][^]. A temporary ceasefire was agreed on April 8, 2026, but Iran's imposition of controls subsequently led to a US naval blockade of Iranian ports from April 13, creating a "dual blockade" [^].
A return to normal traffic is not expected until late 2026 or beyond. Experts and prediction markets suggest a prolonged period before traffic at the Strait of Hormuz returns to pre-aggression levels. The World Bank predicts that transit will not return to these levels until late 2026 [^]. Shipping analysts emphasize that even if a peace agreement is reached, carriers will likely adopt a cautious "wait and see" approach, further delaying a return to normal traffic [^]. Marine intelligence firms like Kpler suggest that if Iran maintains operational control, transit volumes might only reach 40-50% of previous export capacity, and full normalization would not be achievable due to logistical and legal hurdles, including approval processes, mandatory routing through Iranian waters, increased insurance costs, and potential toll payments [^][^]. As of May 6, 2026, Kalshi traders price the chance of tanker traffic returning to normal (defined as a seven-day moving average of over 60 transit calls) before July 1 at 51%, before August 1 at 61%, and before October 1 at 71% [^]. Earlier data from March 24, 2026, showed the odds of traffic returning to normal before April 15 were below 25%, though these odds had improved to over 67% by June 1 and 76% by July 1 in March [^]. In summary, the confluence of ongoing geopolitical tensions, Iran's assertive stance on controlling the waterway, and the inherent caution of the shipping industry suggests that normal traffic levels are unlikely in the immediate future and may not occur until late 2026 or even beyond, if Iran retains its asserted control [^][^][^].
2. Market Behavior & Price Dynamics
Historical Price (Probability)
Outcome probability
Date
This prediction market has demonstrated a consistent and strong downward trend since its inception. The probability of the Strait of Hormuz returning to normal traffic has fallen from a starting point of 19.0% to its current level of 5.7%. The price has been confined to a range between 2.2% and 23.0%, indicating that traders never assigned a high probability to a swift resolution. A particularly significant price movement occurred on April 25, 2026, when the price dropped 9.0 percentage points from 20.0% to 11.0%. According to the available information, this sharp decline was not preceded by any specific news event, suggesting the market may have been reacting to a general shift in sentiment or information not captured in public reporting at the time.
The total trading volume of over one million contracts indicates substantial market interest and conviction in the prevailing trend. While volume fluctuates daily, the overall downward price action shows sellers have been dominant. The price seems to have established a new support level around the 5.7% mark recently, after breaking through previous lows. The market's all-time low of 2.2% serves as a potential floor. Overall, the chart's price action reflects deeply pessimistic sentiment. The market's valuation has steadily decreased, aligning with ongoing reports of severely restricted transit since February 28, 2026, and suggesting traders believe the disruption will be prolonged.
3. Significant Price Movements
Notable price changes detected in the chart, along with research into what caused each movement.
Outcome: Before Aug 1, 2026
📈 May 06, 2026: 11.0pp spike
Price increased from 48.0% to 59.0%
What happened: The primary driver of the 11.0 percentage point spike on May 6, 2026, was likely increased optimism surrounding ongoing US-Iran negotiations [^][^]. This diplomatic momentum followed the pausing of the US's "Project Freedom" escort operation on May 4, 2026, specifically for negotiations with Iran [^][^][^]. The market movement appears to reflect hopes for a diplomatic breakthrough that could lead to a swifter return to normal traffic conditions in the Strait of Hormuz [^][^]. Social media was irrelevant, as no related activity from key figures or viral narratives were identified.
Outcome: Before Jul 1, 2026
📉 May 04, 2026: 11.0pp drop
Price decreased from 46.0% to 35.0%
What happened: The primary driver of the price drop was the worsening situation regarding shipping traffic in the Strait of Hormuz. On May 3, 2026, only 40 ships passed through compared to a pre-war average of 120 daily crossings, with tanker traffic nearly nonexistent on May 4, 2026 [^][^][^][^]. This critical news, indicating persistent and severe disruption, likely reduced market confidence in traffic returning to normal by July 1, 2026. Social media activity was irrelevant as no specific posts or viral narratives were reported around the time of the movement.
Outcome: Before Jun 1, 2026
📉 April 29, 2026: 10.0pp drop
Price decreased from 32.0% to 22.0%
What happened: The primary driver of the prediction market price drop on April 29, 2026, was the reported decrease in ship traffic through the Strait of Hormuz. Traffic was reported at 14 vessels on April 29, a decline from 16 vessels on April 28 [^]. This data indicated a continued deterioration of conditions, making the "Before Jun 1, 2026" outcome less probable. Social media activity was irrelevant as no specific posts or trends were identified for this period.
Outcome: Before Sep 1, 2026
📈 April 27, 2026: 16.0pp spike
Price increased from 58.0% to 74.0%
What happened: The available traditional news sources consistently indicated a prolonged disruption and a slow return to normal traffic at the Strait of Hormuz around April 2026. Reports suggested recovery would take "weeks, if not months," or even six months for mine clearing, even following an April 8 ceasefire [^][^][^]. This information, published before and directly after the April 27, 2026, market spike, contradicts a movement predicting an early normalization by September 1, 2026, rather than supporting it. As no information regarding social media activity or market structure factors coinciding with or leading the price spike on April 27, 2026, is provided in the given sources, the primary driver for this specific movement cannot be identified. Social media's role in this particular price spike is unknown due to a lack of data.
Outcome: Before May 15, 2026
📉 April 25, 2026: 9.0pp drop
Price decreased from 20.0% to 11.0%
What happened: Based on the provided information, no social media activity or traditional news announcement published on or before April 25, 2026, can be identified as the primary driver for the 9.0 percentage point price drop. All available sources are dated after the market movement, describing conditions such as the U.S. expectation of six months for mine clearance and April's traffic at only ~5% of pre-war levels [^]. Therefore, social media was not a primary driver based on the available data, and the movement likely reflected a growing market consensus on a prolonged disruption rather than a specific, timely event.

Market Discussion
Traders in the "When will traffic at the Strait of Hormuz return to normal?" market are heavily debating the timeline, with current probabilities showing a 68% chance of normalization by September 1, 2026. A strong "No" argument, supported by several traders, centers on Iran's asserted control over the Strait, with some citing news about Iran establishing a new authority for the Gulf. Additionally, some users have expressed frustration with the market's resolution process due to issues with the IMF PortWatch data source, impacting their ability to manage capital.
5. What are the key terms of the US-Iran peace proposal mediated by Pakistan, and how could their acceptance or rejection impact the timeline for reopening the strait in 2026?
| Proposed vessel toll/fee | Approximately $2 million (in one report) [^][^] |
|---|---|
| Broader agreement finalization window | Roughly 15–20 days [^][^] |
| Prediction market transit threshold | 7-day moving average of transit calls equal to or above 60 [^][^] |
The US-Iran peace proposal prioritizes resolving the Hormuz crisis and lifting the blockade. Mediated by Pakistan, the proposal primarily focuses on addressing the Hormuz maritime crisis and lifting the US blockade as initial steps, while deferring broader Iran-US nuclear negotiations [^][^][^]. A key component of the proposal involves reopening the Strait of Hormuz as part of ending hostilities and the blockade, incorporating a concept described as "safe passage" or a "legal framework" [^][^][^]. Reports also indicate a potential toll or fee mechanism involving Oman, with one account specifically mentioning approximately $2 million per vessel [^][^]. The framework is structured in two stages: an immediate or extended ceasefire, followed by progress toward a more comprehensive settlement, with one version reportedly allotting approximately 15 to 20 days for finalizing this broader agreement [^][^].
Acceptance of the proposal is uncertain, impacting the Strait's reopening timeline. As of May 7, 2026, US President Donald Trump publicly stated that he was "not satisfied" with the proposal [^]. Similarly, Iran has indicated that it is still reviewing the proposal or has not yet made a final decision [^]. Both of these factors suggest potential delays in a rapid reopening of the Strait of Hormuz [^][^].
The proposal's status directly influences the May 2026 prediction market resolution. A prediction market resolves "Yes" if the IMF Portwatch publishes a 7-day moving average of transit calls equal to or above 60 for any date between market creation and May 31, 2026 [^][^]. Acceptance of a deal that promptly enables reopening should cause the measured transit-call average to surpass this threshold within May 2026 [^]. Conversely, continued rejection or stalled negotiations raise the probability that the near-term resolution (by the end of May) remains "No," potentially pushing normalization later into mid-2026 or beyond [^][^][^].
6. What does naval deployment data from sources like the U.S. Naval Institute reveal about the American and Iranian military postures around the Strait of Hormuz post-April 2026?
| Commercial Transits by May 1, 2026 | Lowest levels since Operation Epic Fury began [^] |
|---|---|
| US Aircraft Deployed | More than 100 [^] |
| Polymarket Probability for Normal Traffic by end of April | 0% [^] |
The U.S. established a secure transit corridor with layered defenses following April 2026, focusing on mine-countermeasure operations and robust protection. This included the transit of destroyers, deployment of unmanned underwater vehicles for mine detection and clearing, and the involvement of three LCS mine-countermeasure package ships [^][^]. The broader layered defense comprised over 100 aircraft, ballistic missile defense-capable destroyers, multi-domain unmanned platforms, and thousands of service members, all with an operational design aimed at protecting forces and supporting transit [^][^].
Iran maintained selective passage, impacting transit despite U.S. efforts to reopen the corridor. Concurrently, Iran upheld a selective passage regime, coupled with mine-related deterrence. USNI reported two Tehran-controlled routes and a 'Tehran tollbooth' that required ships to contact the IRGC for documentation or payment to navigate around Larak Island, thereby creating a risk or permission barrier, even though some U.S. officials described the strait as 'open' [^]. Despite U.S. 'open the corridor' deployments after mid-April, commercial transits through the Strait of Hormuz by May 1, 2026, remained at their lowest levels since Operation Epic Fury began [^]. These initiatives had not yet translated into sustained normal traffic flows, a situation that aligned with a Polymarket market forecast indicating a 0% crowd probability for traffic returning to normal by the end of April, suggesting that normal-level volumes would not be quickly achieved [^].
7. How do the 2026-2027 reopening forecasts from the World Bank and Kpler differ based on their assumptions about Iranian control versus a diplomatic resolution?
| World Bank Normalization Forecast | late 2026 [^][^] |
|---|---|
| Kpler's Control Assumption | strict Iranian control (Phase 1) [^] |
| Kpler's Normalization Outlook | full normalization is not achievable [^] |
The World Bank projects a lengthy recovery for Strait of Hormuz shipping. Normal traffic is not expected to normalize until late 2026, with recovery requiring "a few months" even after the Strait reopens [^][^]. This projection, articulated by World Bank chief Ajay Banga on April 15, 2026, suggests a delayed rather than immediate return to pre-conflict shipping levels [^][^].
Kpler's analysis assumes persistent Iranian control, precluding full normalization. Their forecast is based on a "strict Iranian control" scenario, specifically a Phase 1 "Restricted/Controlled" condition [^]. Under this scenario, full normalization would not be achievable, as access would remain conditional, navigation would be constrained, and elevated risk premia would persist, preventing a return to pre-conflict levels even with increased transits [^].
Direct comparison is difficult due to differing underlying political assumptions. The provided information is insufficient to directly compare the World Bank's and Kpler's forecasts based on specific diplomatic resolution assumptions [^][^][^]. Kpler's outlook explicitly details the implications of an Iranian-control scenario, whereas the World Bank's statements focus on the timeline for recovery post-reopening without specifying the underlying political conditions for that recovery [^][^][^].
8. What are the primary public sources, such as IMF PortWatch, for tracking daily vessel transits through the Strait of Hormuz, and what are their limitations for Q2-Q3 2026?
| Estimated missing vessel traffic | Up to 50% on any given day [^][^] |
|---|---|
| Commercial vessels operating dark (early May 2026) | 146 out of 167 in the Strait of Hormuz area [^][^] |
| Average daily transiting ships (March 1 - April 12, 2026) | 6 to 7 ships [^][^] |
Vessel tracking in the Strait of Hormuz faces significant, persistent challenges for Q2-Q3 2026 due to widespread GPS jamming, AIS spoofing, and vessels intentionally turning off their transponders, often termed "going dark" [^] [^] . These issues result in a substantial portion of actual vessel traffic being missing from standard monitoring systems, with estimates suggesting as much as 50% might be unaccounted for daily [^][^]. For instance, in early May 2026, 146 out of 167 commercial vessels identified in the Strait of Hormuz area were operating dark [^][^]. Military operations and electronic warfare activities in the region further exacerbate these issues, creating electromagnetic complications and unpredictable traffic flows that disrupt civilian tracking systems [^].
IMF PortWatch offers data, but its utility is significantly constrained by these disruptions and a weekly data lag [^] [^] . Although it is a primary public source for daily transit calls and trade volume, the data indicates a severe reduction in vessel transits. Between March 1 and April 12, 2026, an average of only 6 to 7 ships passed through daily [^][^]. Current traffic patterns are highly selective, with most inbound tankers involved in Iranian oil transportation, while clean tankers or Very Large Crude Carriers are largely absent [^][^].
Degraded visibility suggests no return to normal transit levels soon for Q2-Q3 2026. Given the constrained commercial movement and persistent military pressure, a return to pre-conflict transit levels is not expected unless there is a significant de-escalation of regional tensions [^][^]. The highly selective nature of current transits, with some vessels utilizing Iranian territorial waters, suggests that a controlled, permission-based transit model is currently in place [^][^].
9. How might the establishment of Iran's Persian Gulf Strait Authority (PGSA) and its toll requirements affect international maritime law and delay normalization beyond Q4 2026?
| Traffic Reduction (Week Ending May 3, 2026) | Over 96% from peacetime levels [^][^][^] |
|---|---|
| Projected Normalization of Traffic | Beyond Q4 2026 [^][^][^][^] |
| Imposed Tolls by PGSA | Up to $2 million per ship [^][^][^][^][^][^][^] |
Iran's establishment of the Persian Gulf Strait Authority (PGSA) and its toll requirements generally violate international law [^] [^] [^] [^] . Many maritime law experts and states, including the United States, assert that the United Nations Convention on the Law of the Sea (UNCLOS) guarantees transit passage through the Strait of Hormuz, binding all states. However, Iran, which is not a party to UNCLOS, disputes this, claiming the right to apply an "innocent passage" regime and deny access to vessels associated with "aggressor parties." This stance persists despite Oman, the other coastal state, rejecting the toll proposal [^][^][^][^][^][^][^][^][^]. Furthermore, the U.S. has threatened sanctions against entities that pay Iran for transit [^][^].
These actions already significantly disrupt Strait of Hormuz maritime traffic and global energy markets [^] [^] [^] . In the week ending May 3, 2026, traffic saw a reduction of over 96% from peacetime levels, contributing to sharp increases in global energy prices [^][^][^]. The imposition of tolls, reportedly up to $2 million per ship, along with requirements to use specific corridors and the risk of U.S. sanctions, has introduced substantial operational complexities for shippers. This has led to higher freight rates and increased war risk premiums for vessels traversing the strait [^][^][^][^][^][^][^].
10. What Could Change the Odds
Key Catalysts for Strait of Hormuz Shipping
Traders on the Kalshi prediction platform, as of May 6, 2026, estimated a 91% chance that shipping conditions in the Strait of Hormuz will return to normal levels before July 1, 2027 [^] . The World Bank, in a May 2026 report, predicted that transit through the Strait would not return to pre-conflict levels until late 2026 [^]. Surveys of oil and natural gas executives in April 2026 showed varied expectations for a return to normal traffic, with a significant portion anticipating it in August or November of 2026, and 14% expecting it to take even longer [^]. Key bullish factors that could lead to normalization include advancements in US-Iran deal talks, with reports of Iran reviewing new U.S. proposals to end the conflict [^][^][^]. De-escalation of conflict, such as agreements to allow neutral ships to transit or a reduction in military confrontations, could also improve conditions [^]. The US had attempted to escort vessels through "Project Freedom," although this initiative was suspended [^][^]. Furthermore, some analyses suggest Iran is more vulnerable to a prolonged closure of the Strait than its adversaries, potentially incentivizing a resolution [^][^]. Iraq has also offered crude discounts to encourage shipping through the Strait despite elevated risks [^].
Conversely, several bearish factors indicate continued disruption. Ongoing US-Iran tensions and conflict, including escalating tensions, reported attacks by both sides, and a continued U.S. naval blockade, significantly hinder normalization [^][^]. Iran's establishment of a "Persian Gulf Strait Authority" and its demand for fees for transit suggest an intent to formalize its leverage over the chokepoint, which could complicate a return to unrestricted passage [^]. Iran has also rejected some US proposals and put forth its own demands in negotiations [^][^][^]. Vessel owners remain reluctant to transit without firm security guarantees and absolute assurances of safety, leading to increased insurance premiums and operational uncertainty [^][^]. Additionally, regional refining capacity and infrastructure have been damaged during the conflict, which could take years to fully rebuild, impacting overall shipping activity [^]. The involvement of groups like the Houthis in the conflict could also expand disruptions to other critical waterways, further delaying normalization efforts [^]. A substantial 48% of executives believe future geopolitical disruptions in the Strait within the next five years are "very likely" [^].
