final rationale
Mean of 5 draws (0.20, 0.19, 0.23, 0.23, 0.23). (0) The condition is not met. The latest IMF PortWatch data I could find (via secondary trackers, through 2026-09-27) shows the Hormuz 7-day average at roughly 1–3 transits a day. Since the war began, the series has never been shown above about 32 (MacroMicro, 2026-07-05). Early July averaged about 18 a day before fighting resumed on July 8, so nothing in the window so far counts. (a) About 12 weeks remain until Dec 31, and PortWatch publishes with a lag of a week or more, which slightly shortens the effective window. (b) Status quo is NO: Iran says the strait stays shut until its seven conditions are met, Trump rejected Iran's proposal on Sept 26 and talks of bombing after the midterms, and tankers are still being struck. (c) NO: talks drag on or the US escalates after November, so the 7-day average stays in single digits through year-end. (d) YES: Iran's seven-day plan (still in Qatari-mediated talks) is accepted, perhaps before the midterms. The 200+ ships holding position, plus existing US escort operations, then push daily transits back toward the pre-war level of 74–93, clearing a 40 average within a week or two. My rough estimate is a 25–30% chance of a durable deal by early December, and about a 65–70% chance it lifts the average above 40 in time, given the June precedent of slow, mine- and crew-safety-limited recovery. That gives about 18–20%. This sits just under Kalshi's 23% and consistent with the sibling above-60 market at 14% and Polymarket's 'normal by Dec 31' at 18.5%, which should price lower than the easier 40 bar.

Research loops, bottom lines
- current state: As of the latest published IMF PortWatch data (2026-09-27), the Strait of Hormuz 7-day moving average of transit calls is around 1–3, roughly 1–3% of the pre-crisis baseline of ~74-85/day, amid ongoing war, Iranian closure declarations, and active attacks on shipping, with no confirmed reopening deal — making a jump above 40 before January 1, 2027 look highly dependent on an as-yet-unachieved diplomatic breakthrough.
- base rate: Historically (pre-2026) a 7DMA above 40 was the permanent norm, but since the Feb 2026 war the metric has never been confirmed to exceed the high-30s even at its best ceasefire-era peak (late June/early July 2026), and it has since collapsed to near-total closure (~1-3/day) amid failed diplomacy and an active naval blockade as of early October 2026; comparable "return to normal" markets with a higher (60) threshold price only 14% by Jan 1, 2027, implying the lower 40-threshold outcome, while mor
- yes case: The clearest YES path is a US-Iran deal built on Iran's standing "seven-day" reopening mechanism (last negotiated Sept–Oct 2026, still alive via Qatari mediation despite Trump's Sept 26 rejection), combined with a large staged fleet and already-operating U.S. escort/STS logistics that industry sources say could push transit counts up quickly once security is assured — but this requires a political breakthrough that has not yet occurred as of Oct 5, 2026, with Trump publicly contemplating resumed
- no case: Every verifiable data point through October 5, 2026 — the frozen PortWatch series at ~1 transit/day, a rejected Iranian reopening offer, hard-line Iranian pre-conditions, reported US bomber redeployment and talk of post-midterm escalation, rising numbers of AIS-visible vessels holding position rather than transiting, and an insurance/crew-safety mechanism that structurally lags any political deal — all support status-quo inertia keeping the 7DMA far below 40, with no confirmed instance of the me

NOT FOUND: A current, officially-updated IMF PortWatch chart/CSV value beyond 2026-09-27 (the resolution source appears to have a multi-day publication lag); no confirmed signed ceasefire or reopening agreement as of October 5, 2026.
BOTTOM LINE: As of the latest published IMF PortWatch data (2026-09-27), the Strait of Hormuz 7-day moving average of transit calls is around 1–3, roughly 1–3% of the pre-crisis baseline of ~74-85/day, amid ongoing war, Iranian closure declarations, and active attacks on shipping, with no confirmed reopening deal — making a jump above 40 before January 1, 2027 look highly dependent on an as-yet-unachieved diplomatic breakthrough.
report: base rate
- [2025 baseline] Pre-crisis, the Strait of Hormuz 7-day moving average (7DMA) of transit calls
averaged 93.7 across 2025, reached 107.3 on 24 February 2026 just before the disruption, fell to a low of 2.7 in late March 2026
— i.e., historically the metric sat far above 40 nearly all the time, and "above 40" was the norm, not the exception, before the 2026 war.
- [2026-02-28 onward] A war between the US/Israel and Iran closed the strait; per Wikipedia's Strait of Hormuz campaign timeline
on 19 March 2026 the US began an aerial campaign to reopen the strait, and on 13 April 2026 the US imposed a naval blockade on Iran after Islamabad Talks failed
, keeping traffic depressed for most of the year.
- [2026-04 to 2026-07 ceasefire window] During the April 8–July 8, 2026 ceasefire, traffic partially recovered but never reached "normal" (60+) and reporting suggests it hovered well under 40 for most of the period: one tracker noted
"Recovery has been partial and uneven: 8.5 per day in April, 6.5 in May, 15.1 in June, and 18.2 for 2026-07-01 through 2026-07-19"
, with
"The strongest single day since the collapse was 2026-06-24 with 51 transits — still 43% below the February daily average."
- [2026-06-22] A Manifold/Polymarket analyst noted
Iran re-closed the strait on Jun 22 over the Lebanon strikes, with traffic plunging to ~12 ships/day from ~21, and the single best post-MoU reopening on Jun 19 peaked at only ~20 tankers — still ~1/5 of the ~93–100/day prewar baseline
, illustrating that even during the most favorable ceasefire stretch the 7DMA likely stayed below 40, let alone 60.
- [2026-07-05, just before window start] MacroMicro's tracked series shows the Hormuz 7DMA at only 32.14 on 2026-07-05 — i.e., even at the peak of the ceasefire-driven partial recovery, right before this question's window opens (July 6), the average had not yet cleared 40.
- [2026-07-08] Fighting resumed (per Wikipedia's ceasefire article, outcome lists
"Fighting resumes on 8 July"
), collapsing traffic again shortly after the question's start date.
- [2026-09-27, most recent PortWatch data] Traffic has since collapsed to near-total closure:
"The Strait of Hormuz remains effectively closed to commercial traffic, with IMF PortWatch recording 1 transit on 2026-09-27 against a pre-crisis baseline of 85 per day."
- [2026-09-26/09-27] Diplomacy has stalled rather than progressed:
Trump rejected Iran's conditional proposal for reopening the Strait, telling aides he expects to resume bombing after November's midterms, and confirmed "They made a proposal but I rejected it."
- [2026-10-04] As of the latest brief, Iran is publicly conditioning reopening on US concessions:
straits.live reports Al Jazeera's account that Iran's negotiator says the strait will not reopen until the US meets seven conditions, including ending the naval blockade
— i.e., no near-term reopening in sight as of the report date.
- [Forecaster base rates] A RAND Forecasting Initiative community question on the highest 7DMA reached between May 8–Dec 31, 2026 put only 12% initial probability on the 50-100 "highest ever reached" bucket combined with the 25-50 bucket at 12% and 35% on 75-100 and 30% on ≥100 (i.e., optimistic about eventual full recovery reaching high values at some point, but this is about the *peak* reached, not a sustained post-closure average, and was set before the July 8 re-escalation).
- [Sibling Kalshi markets, same metric, higher threshold] As of Oct 4-5, 2026, Kalshi's companion ladder using the "above 60" threshold (a higher, stricter bar than this question's "above 40") priced "before Jan 1, 2027" at 14%, "before Dec 1, 2026" at 7%, and "before Nov 1, 2026" at 3%, while a looser "before Jul 1, 2027" bar priced 45%. A Polymarket sibling ("returns to normal by December 31") priced similarly at 19%. These suggest market consensus assigns low-to-moderate odds even to a *sustained* recovery to 60 within the window, though the 40-threshold version of this question should price somewhat higher than these given the lower bar.
NOT FOUND: An explicit historical instance of the IMF PortWatch 7DMA crossing above 40 at any point since the war began (Feb 28, 2026) — all located sources suggest the peak during the April–July ceasefire topped out in roughly the 30s before falling back below 40 by the question's July 6 start date, and no report found of the 7DMA exceeding 40 since. No official IMF PortWatch dataset was fetched directly (secondary trackers only).
BOTTOM LINE: Historically (pre-2026) a 7DMA above 40 was the permanent norm, but since the Feb 2026 war the metric has never been confirmed to exceed the high-30s even at its best ceasefire-era peak (late June/early July 2026), and it has since collapsed to near-total closure (~1-3/day) amid failed diplomacy and an active naval blockade as of early October 2026; comparable "return to normal" markets with a higher (60) threshold price only 14% by Jan 1, 2027, implying the lower 40-threshold outcome, while more likely, is still a clear minority-probability event absent a durable ceasefire and reopening well before year-end.
report: yes case
YES means: the IMF PortWatch 7-day moving average of Strait of Hormuz transit calls climbs back above 40 at some point between July 7, 2026 and December 31, 2026 — i.e., a durable (even if partial) reopening occurs well before year-end, pushed by a US-Iran deal or unilateral de-escalation.
- [2026-09-22] Iran transmitted a concrete, time-boxed reopening mechanism: Araghchi's "seven-day plan" delivered via Qatari mediators at UNGA states that "if certain conditions are met, the Strait of Hormuz would be open on the end of the seventh day" — a path by which a political agreement could translate into a fast, dated reopening rather than a slow ramp. https://thehill.com/policy/international/6112561-iran-us-seven-day-peace-plan/
- [2026-10-04] Diplomacy, while stalled, is still active and not dead: Washington Times reports Iran's Deputy FM said Iran "is reviewing the U.S. response to the seven-day peace proposal," and that the proposal "would have established a framework agreement leading to the reopening of the Strait of Hormuz and a comprehensive ceasefire after one week." https://washingtontimes.com/news/2026/oct/4/iranian-leaders-focus-diplomatic-talks-us-adds-military-muscle
- [2026-09-26] Even while rejecting the deal, Trump's own framing implies current throughput may already exceed the headline PortWatch count: he told reporters "Last night we had 29 ships come out," a figure far above the "1 vessel" PortWatch logged for Sept 27 — suggesting either a methodology/reporting lag or a parallel (convoy/STS) flow that could feed into a rapid PortWatch jump once formally counted or once direct transits resume. https://thehill.com/homenews/administration/6113000-trump-iran-proposal-ceasefire/
- [2026-10-04] A secondary outlet (Time News) reports that, despite the Strait itself remaining near-closed, "the vast majority of traffic through the strategic maritime chokepoint has returned to a regular cadence" via U.S. military-escorted convoys and ship-to-ship transfers, with JPMorgan data showing regional Middle East crude exports "recovered to about 98 percent of pre-conflict levels" — evidence that the physical capacity and logistics (escorts, convoy operations) needed to push direct transit counts back up already exist and are operating at scale, even if not yet counted as Strait transits. https://time.news/strait-of-hormuz-oil-shipments-rebound-toward-pre-war-levels/
- [2026-06-11] Industry precedent supports a fast-ramp scenario once a deal is reached: Frontline CEO Lars Barstad said "I'm actually very optimistic the minute the tide turns and the U.S. and Iran have found some sort of agreement... those transits are going to resume pretty quickly," citing roughly 10% of the world's VLCC fleet already staged and loaded in the Gulf ready to exit immediately. https://www.cnbc.com/2026/06/11/iran-strait-hormuz-oil-tanker-traffic-frontline.html
- [2026-10-04] A large stranded fleet remains positioned at the chokepoint, giving any reopening a ready-made surge: straits.live's live monitor counted "218 AIS-visible vessels... holding position away from berth in the Strait of Hormuz and Gulf watch box" as of Oct 4, a pool of ships that could transit in a short window if security assurances are given. https://straits.live/
- [2026-09-25] Iran has signaled political urgency to close a deal within this question's window: Araghchi said "it would be better" if an agreement were reached before the U.S. midterm elections (Nov 2026), giving a concrete near-term deadline that, if met, would fall comfortably inside the Jan 1, 2027 resolution window. https://www.inquirer.com/news/nation-world/iran-seven-day-plan-end-war-20260925.html
- [2026-09-29] Talks have not fully collapsed despite the rejection: EA WorldView's live-updates log reports that "Mediators will hold separate talks with the US and Iran," focused on "an amended version of Iran's proposal for a resumption of negotiations and the opening of the Strait of Hormuz within seven days" — i.e., an amended/renegotiated version of the same fast-reopening mechanism remains on the table. https://eaworldview.com/2026/10/us-war-on-iran-trump-rejects-tehran-proposal-to-reopen-talks-and-strait-of-hormuz/
- [2026-04-08 precedent] The war has already produced one rapid, deal-triggered reopening attempt: when Trump and Iran agreed a two-week ceasefire conditioned on Hormuz access, Iran's FM Araghchi stated "For a period of two weeks, safe passage through the Strait of Hormuz will be possible," showing that a presidential-level deal can trigger an immediate (if fragile) reopening announcement, which is the recurring template still being negotiated as of October. https://aljazeera.com/news/2026/4/7/trump-suspends-iran-bombing-for-two-weeks-following-dire-threats
BOTTOM LINE: The clearest YES path is a US-Iran deal built on Iran's standing "seven-day" reopening mechanism (last negotiated Sept–Oct 2026, still alive via Qatari mediation despite Trump's Sept 26 rejection), combined with a large staged fleet and already-operating U.S. escort/STS logistics that industry sources say could push transit counts up quickly once security is assured — but this requires a political breakthrough that has not yet occurred as of Oct 5, 2026, with Trump publicly contemplating resumed bombing after the November midterms rather than imminent de-escalation.
NOT FOUND: No confirmed signed agreement, signing date, or PortWatch data point above 40 at any time since the Feb 28, 2026 war began; no direct, dated reconciliation between the "29 ships" Trump quote and official PortWatch methodology.
report: no case
YES means: the real-world outcome where IMF PortWatch's published 7-day moving average of Strait of Hormuz transit calls climbs above 40 at some point between July 7, 2026 and December 31, 2026 inclusive. This dimension argues the NO case — that this threshold will not be crossed in that window.
- [2026-10-05] As of the most current straits.live brief, IMF PortWatch's own published series is still frozen at "1 transit on 2026-09-27, against a pre-crisis baseline of 85 per day" — eight days stale relative to today, with no newer official data point released, underscoring that even a late-window recovery may not be visible/confirmable before the Jan 1 cutoff given PortWatch's weekly-plus lag. https://straits.live/briefs/2026-10-05
- [2026-10-04] The tracker's own headline composite states
the latest official PortWatch count is 1 vessel on September 27 at 1% of typical; war-risk premiums at 40× normal; crisis pressure at 88 (extreme)
— a crisis-pressure reading far beyond anything seen even during the best ceasefire stretch, implying no near-term mechanical path to a 40-call average. https://straits.live/
- [2026-09-26] Direct, on-the-record evidence diplomacy has stalled rather than advanced since the colleague reports' last update:
"I rejected their deal... They want to make a deal where they open the strait immediately because they're losing so badly," Trump told reporters
, after Iran's proposal to revive a ceasefire and reopen the strait. https://www.nbcnews.com/world/iran/iran-says-choice-reopening-hormuz-rests-united-states-offer-rcna599956
- [2026-10-04] Iran's negotiating posture remains a hard pre-condition, not a phased reopening:
Iran presented a proposal during the UN General Assembly under which the Strait of Hormuz waterway could be reopened and normal maritime passage restored within seven days if the conditions were met, with the US replying to this proposal last week via Qatari intermediaries
— i.e., the structure requires a full US concession package before any traffic resumes, not a gradual ramp that could sit anywhere near 40 for a sustained period. https://huffpost.com/entry/strait-of-hormuz-closure_n_6ac24247e4b0bc90e3ff8ae5
- [2026-10-04] Washington Times reporting indicates the US is still oriented toward escalation, not de-escalation:
Iranian officials signaled on Sunday that peace negotiations with the U.S. are continuing, even as Washington prepares for a potential escalation in the war later this year and Iran-backed Houthi rebels in Yemen threaten global energy markets
, consistent with the colleagues' note that Trump expects to resume bombing after the midterms. https://washingtontimes.com/news/2026/oct/4/iranian-leaders-focus-diplomatic-talks-us-adds-military-muscle
- [2026-10-05] Military posture signals further escalation risk rather than stand-down: per straits.live's Oct 5 brief,
All U.S. bombers have left a UK air base amid suspected terror plot concerns and more tankers were struck near Iran, per CNBC, not independently confirmed in this feed
— a reported bomber redeployment that, if confirmed, points toward active contingency planning rather than imminent reopening. https://straits.live/briefs/2026-10-05
- [2026-10-04] Attacks on shipping remain frequent and are intensifying the insurance-driven shutdown mechanism:
the IRGC claimed via the semi-official Fars news agency, as relayed by Hellenic Shipping News, that its navy targeted at least seven tankers in the strait over five days
, which — even if contested — keeps underwriters from normalizing cover. https://straits.live/briefs/2026-10-05
- [2026-09ish, "ceasefire buckles" report] The structural reason recovery is slow even after any deal is explained directly by an industry source:
The more immediate constraint on Gulf shipping is not insurance availability but crew safety. "The Strait of Hormuz is not seeing those transits because of insurance challenges. It's not seeing those transits because of the safety of the crew, safety of the cargo, and the vessel," said Rahul Kapoor
, meaning even a signed political deal would not instantly translate into a 40+ transit average — a lag mechanism that argues against a quick jump within the remaining ~3-month window. https://www.insurancebusinessmag.com/us/news/marine/report-warrisk-insurance-braces-for-prolonged-elevated-premiums-as-hormuz-ceasefire-buckles-580558.aspx
- [2026-10-01/02] AIS-visible vessels holding position away from berth have been rising, not falling, across the most recent days (147 on Oct 2, 156 on Oct 4, 218 on Oct 4 evening, 239 on Oct 5), per straits.live's running counts — a stockpile of waiting traffic that, even if released, implies a surge risk but currently shows no actual movement through the strait. https://straits.live/briefs/2026-10-05
- [2026-04/2026-06 precedent] The strongest-documented precedent for a 40-call average (the April–July ceasefire) topped out at MacroMicro's tracked 32.14 on 2026-07-05, confirming the 7DMA has never been shown to cross 40 at any point since the war began on Feb 28, 2026 — a fact that still holds as of this report's date with no newer contradicting data published. (Fact previously established in colleague reports, reaffirmed here as still the all-time high-water mark through Oct 5.)
- [2026-10-01] Mixed signal worth noting for calibration: straits.live's own Oct 1 brief flags
CNBC notes that crude exports through the strait have returned toward prewar levels but that fuel shipments remain constrained, cautioning that the recovery relies on US military protection of tankers; no major wire in this feed carries that throughput claim independently
— an unconfirmed, single-source claim of partial crude-only recovery that, even if true, would not necessarily be captured in PortWatch's all-vessel-type transit-call metric, and has not been corroborated elsewhere.
BOTTOM LINE: Every verifiable data point through October 5, 2026 — the frozen PortWatch series at ~1 transit/day, a rejected Iranian reopening offer, hard-line Iranian pre-conditions, reported US bomber redeployment and talk of post-midterm escalation, rising numbers of AIS-visible vessels holding position rather than transiting, and an insurance/crew-safety mechanism that structurally lags any political deal — all support status-quo inertia keeping the 7DMA far below 40, with no confirmed instance of the metric ever exceeding roughly 32 since the war began.
NOT FOUND: A confirmed, dated PortWatch data point after 2026-09-27; any signed US-Iran agreement or Iranian announcement of an actual reopening date; independent confirmation of the reported US bomber withdrawal from the UK or of the IRGC's seven-tanker claim.

(0) The condition is not met. The latest IMF PortWatch data I could find (via secondary trackers, through 2026-09-27) shows the Hormuz 7-day average at roughly 1–3 transits a day. Since the war began, the series has never been shown above about 32 (MacroMicro, 2026-07-05). Early July averaged about 18 a day before fighting resumed on July 8, so nothing in the window so far counts. (a) About 12 weeks remain until Dec 31, and PortWatch publishes with a lag of a week or more, which slightly shortens the effective window. (b) Status quo is NO: Iran says the strait stays shut until its seven conditions are met, Trump rejected Iran's proposal on Sept 26 and talks of bombing after the midterms, and tankers are still being struck. (c) NO: talks drag on or the US escalates after November, so the 7-day average stays in single digits through year-end. (d) YES: Iran's seven-day plan (still in Qatari-mediated talks) is accepted, perhaps before the midterms. The 200+ ships holding position, plus existing US escort operations, then push daily transits back toward the pre-war level of 74–93, clearing a 40 average within a week or two. My rough estimate is a 25–30% chance of a durable deal by early December, and about a 65–70% chance it lifts the average above 40 in time, given the June precedent of slow, mine- and crew-safety-limited recovery. That gives about 18–20%. This sits just under Kalshi's 23% and consistent with the sibling above-60 market at 14% and Polymarket's 'normal by Dec 31' at 18.5%, which should price lower than the easier 40 bar.

(0) Not met. The latest IMF PortWatch data available through secondary trackers (straits.live, aegeanintel), dated 2026-09-27, shows about 1 transit that day and a 7-day average of roughly 1–3. Since the war began the 7DMA has never been confirmed above 40; the best ceasefire-era reading was MacroMicro's 32.14 on July 5, before the window opened, and traffic collapsed again when fighting resumed July 8. Nothing has crossed the bar since July 6. (a) About 12 weeks remain until Dec 31, and PortWatch publishes with a lag of roughly a week, so a crossing has to happen by late December. (b) Status quo is NO. Iran says the strait stays shut until seven conditions are met, Trump rejected the Sept 26 proposal and talked about resuming bombing after the midterms, attacks on tankers continue, and vessels holding position in the Gulf are increasing. (c) NO: talks drag on or escalation follows the midterms; even if a late deal comes, insurance and crew-safety lags keep the 7DMA below 40 through December, as in June, when a reopening peaked in the low 30s. (d) YES: an amended version of Iran's 'seven-day' plan is agreed via Qatari mediators before or soon after the midterms. The 200+ staged vessels then surge through, pushing the 7DMA past 40 within a couple of weeks. I anchor on Kalshi's 23% (bid 19 / ask 24). The sibling 'above 60 by Jan 1' market at 14% and Polymarket's 'normal by Dec 31' at 18.5% fit a modestly higher number for the 40 threshold. Given the hardening of positions this past week and the documented slow post-deal ramp, I shade slightly below the mid, to 19%.

No supplied source documents a qualifying crossing, but the direct IMF PortWatch fetch returned only navigation text, so historical non-occurrence is not independently verified. About 88 days remain until January 1, 2027—not the January 5 trading close—and YES requires at least one qualifying seven-day average above 40 dated within the specified window. I retain Kalshi's 23% YES anchor (19% bid/24% ask), because the research provides no clearly unpriced, reliably verified reason to depart; Polymarket's 18.5% 'returns to normal' contract is context, not an identical question. If conditions remain unchanged, NO wins: secondary trackers report one daily transit on September 27 and approximately three for the seven-day average on October 1, although neither figure was verified against the official dataset. A NO scenario is continued failed negotiations and attacks deterring crews, consistent with the September 26 rejection reported by NBC and the October 4 reopening conditions reported by MarineLink; even the earlier partial recovery registered only 32.14 on July 5 in the cited MacroMicro series. A YES scenario is an agreement implementing the still-discussed seven-day reopening proposal, followed by sufficient staged vessels clearing the strait to lift one rolling average above 40, without requiring permanent normalization. I discount physical-reopening scenarios for measurement risk: recovered oil exports, ship-to-ship transfers, and the unverified '29 ships' statement do not establish qualifying PortWatch transit calls. Publication lag adds uncertainty but does not necessarily exclude subsequently published observations dated before January 1; the missing official series and dependence on overlapping secondary trackers materially limit forecast confidence.

No supplied source documents an eligible crossing above 40, and the direct IMF PortWatch fetch returned navigation rather than observations, so neither an already-resolved YES nor an impossible YES is established. About 88 days remain until January 1, 2027—not the January 5 trading close—and one qualifying seven-day-average observation after July 6 and before January 1 is sufficient. I retain Kalshi’s 23% YES anchor (19% bid/24% ask), because the research provides no sufficiently verified, overlooked information to justify moving away from it. The status quo implies NO: secondary trackers citing PortWatch report roughly 1–3 daily transits in late September/early October, although their single-day counts and claimed moving averages are not interchangeable or directly verified. A NO scenario is continued diplomatic failure and unsafe passage, supported by the September 26 rejection reported by NBC and Iran’s October 4 reopening conditions reported by Marine Link; MacroMicro’s reported July 5 average of 32.14 also illustrates that partial reopening need not clear 40. A YES scenario is an agreement through the still-active negotiations reported by the Washington Times on October 4, followed by implementation of the proposed seven-day reopening and enough waiting vessels transiting to produce one qualifying average, without requiring permanent normalization. Trump’s reported '29 ships' statement and claims of near-normal crude exports do not establish the resolving metric, since cargo volumes, convoy activity, and PortWatch-counted transit calls can differ substantially. Missing official historical observations, potentially shared sourcing among trackers, and reporting lags or revisions materially limit confidence; delayed publication could affect confirmation, but the supplied rules do not establish that a qualifying December observation published later would automatically be excluded.

(0) The condition is not documented as already met: the official PortWatch page could not be read numerically, while multiple secondary trackers citing its latest September 27 data place the 7-day average around 1–3, and no source found a post-July 6 reading above 40. The inaccessible official series and its multi-day publication lag create some settlement uncertainty, but the available evidence indicates the threshold remains far away. (a) Roughly 87 days remain from October 5 through December 31, 2026, enough for a negotiated reopening but not much time for talks, security normalization, and a seven-day average to recover. (b) If nothing changes, continuing hostilities, attacks, Iran's closure conditions, and vessels waiting rather than transiting produce No. (c) No results if negotiations remain stalled or any agreement comes too late or proves too fragile for traffic to average above 40 for seven days. (d) Yes results if the active US-Iran negotiations yield a reopening by roughly mid-December and the staged fleet rapidly surges through under security guarantees. I anchor at Kalshi's 23% Yes price and retain it because the recent rejection of Iran's proposal and renewed attacks offset the concrete seven-day reopening plan and rapid-recovery capacity, while the related 60-threshold markets are contextual rather than exact-question anchors.
