final rationale
Mean of 4 draws (0.11, 0.12, 0.16, 0.16). (0) The condition is not met yet. AAA's resolution page shows diesel at $6.4839 on 9/26/26, below the all-time record of $6.5276 set on 9/22, so the price would need to rise about 8% more by November 3. (a) About 38 days remain until the single-day AAA reading on November 3. (b) If nothing changes, diesel stays near $6.45–6.50 and the market resolves No. The latest daily readings are drifting down from the peak: $6.53, then $6.51, $6.50, $6.48. (c) NO scenario: rack diesel's roughly 6.4% weekly drop (to $4.79) and crude's roughly 6% decline feed into retail over the next one to two weeks. Iran's seven-day Hormuz reopening offer or a possible US diesel export restriction then lowers prices, and diesel ends near $6.00–6.40. (d) YES scenario: the Hormuz talks collapse again, as the June MOU did. Russia extends its export ban and Ukrainian refinery strikes continue, crack spreads widen further, and the early-September pace of about 3 cents a day resumes, pushing diesel past $7. In a crisis-volatility regime, an 8% move in five weeks is roughly a one-sigma event, but the drift now looks negative. The code-execution output started from a wrong price ($3.77) and should be ignored. The Kalshi anchor is 15–18%. The fresh wholesale and crude declines point to a plateau or reversal, so I shade slightly below the market while keeping real jump risk for a renewed escalation.

Research loops, bottom lines
- current state: As of September 25, 2026, AAA's own national average diesel price sits at $6.50/gallon — a fresh all-time record set within the past week ($6.53 on 9/22) — roughly 93 cents above the $7.00 threshold, and the price trajectory over the past three weeks has been a rapid, roughly linear climb from ~$5.85 (Sept 4) to ~$6.50 (Sept 25), driven by an unresolved refining-capacity/geopolitical supply shock rather than crude cost.
- base rate: The outside view strongly favors "No": diesel has never in AAA's recorded history reached $7.00 (current all-time record is $6.53, set 9/22/26, and the price has been essentially flat-to-slightly-declining in the most recent daily readings), and the leading independent forecaster (EIA STEO, Sept. 2026) projects diesel averaging $5.55/gal in Q4 2026 — well below $7. A move from ~$6.50 to above $7.00 within roughly five weeks would require a fresh, larger supply shock than any seen even during the
- yes case: The single most credible mechanistic path to YES is continuation of the same refining-margin-driven rate of increase seen since September 4 (~3 cents/day), which if sustained through November 3 would push the national average well past $7; this is reinforced by dated, named-source forecasts (Eurasia Group's Brew, EIA-linked crack-spread projections through November, and a possible Russian export-ban extension "through the end of the year") that explicitly place the disruption's duration past the
- no case: The most recent (Sept. 22–25) data shows crude prices falling, wholesale diesel dropping ~6.4% in a single week, a concrete (if fragile) Iranian reopening offer on the table, and EIA's own crack-spread forecast implying a plateau rather than further escalation through November — all pointing to diesel stalling near its current ~$6.50 record rather than climbing another ~$0.50/gal (nearly 8%) to clear $7.00 by November 3.

report: current state
- [2026-09-25] AAA's official gasprices.aaa.com page (fetched directly) shows the "Current Avg." diesel price at
Today's AAA National Average $4.4918, Price as of 9/25/26
, with the national gas price table listing diesel at $6.5019 for Current Avg., $6.5141 Yesterday Avg., $6.4476 Week Ago Avg., $5.6199 Month Ago Avg., and $3.6890 Year Ago Avg.
- [2026-09-22] AAA's own "highest recorded average price" table (fetched from gasprices.aaa.com) lists the all-time diesel record as $6.5276 set on 9/22/26, confirming diesel is currently at/near record levels just five weeks before the question's Nov 3 deadline.
- [2026-09-22]
Diesel continued to set records, with AAA saying the national average retail price for diesel fuel Monday hit an all-time high of $6.51 per gallon.
- [2026-09-24] Third-party tracker MacroMicro (sourcing AAA data) shows diesel at
Diesel · 2026-09-24 · 6.51USD/Gallon · 6.52USD/Gallon
, corroborating AAA's site.
- [2026-09-04] Diesel first crossed the prior 2022 record:
the AAA national average price for diesel fuel reached a new record high of $5.85 as of Sept. 4, 2026, surpassing the prior high of $5.8159 set back in June 2022.
- [2026-09-11]
According to AAA data, the national average diesel price reached about $6.05 per gallon on Sept. 11, 2026, surpassing the previous record established in June 2022.
- [2026-09-14]
The national average price of diesel climbed to a record $6.23 per gallon on Sept. 14, after first breaking above the $6 threshold last week.
- [2026-09-22] Axios reporting attributes the surge to geopolitics/refining constraints:
Ukrainian attacks have damaged significant chunks of Russian energy infrastructure... crude oil prices fell Monday, but prices for key refined products such as diesel, gasoline and jet fuel pushed higher, reflecting the shortages in refining capacity.
- [2026-09-01] Underlying refining-margin driver:
the U.S. Gulf Coast diesel crack spread (the price difference between diesel and crude oil) surged past $100 per barrel on September 1, 2026... a fivefold jump from its pre-conflict baseline of approximately $20 per barrel, which signals high product scarcity and an unprecedented refining premium.
- [2026-09-21] A structural (not crude-driven) explanation for the record run:
Record diesel prices hit $6.29 a gallon while U.S. refineries ran at 97%. The cause isn't a crude shortage. It's refining capacity and exports.
- [2026-09-09] EIA's own short-term outlook was already anticipating elevated diesel through year-end:
In its Sept. 9, 2026, Short-Term Energy Outlook, the EIA raised its forecast for the average U.S. retail diesel price to $5.07 per gallon for 2026... it raised its 2027 forecast to $4.40 per gallon
(note: these are annual averages, not point-in-time forecasts, so they understate the current spot level).
- [2026-09-22] Underlying supply-shock drivers remain unresolved as of the latest reporting:
the six-month de facto closure of the Strait of Hormuz, Russia's diesel export ban, U.S. refinery operable utilization maxing out at 98 percent... Russia was a major exporter of diesel – accounting for about 10 percent of global seaborne-traded diesel supplies.
BOTTOM LINE: As of September 25, 2026, AAA's own national average diesel price sits at $6.50/gallon — a fresh all-time record set within the past week ($6.53 on 9/22) — roughly 93 cents above the $7.00 threshold, and the price trajectory over the past three weeks has been a rapid, roughly linear climb from ~$5.85 (Sept 4) to ~$6.50 (Sept 25), driven by an unresolved refining-capacity/geopolitical supply shock rather than crude cost.
NOT FOUND: No official AAA statement or news report giving a specific point forecast for the November 3, 2026 diesel price; no confirmation of any resolution to the Strait of Hormuz closure or Russian refinery/export disruptions that would signal an imminent price reversal before the market's close.
report: base rate
- [2026-09-25] The AAA "Current Avg." diesel price was
$4.4918 for regular gasoline as of 9/25/26
, and per AAA's own table, diesel's current average that day was $6.5019/gal, down slightly from $6.5141 the prior day, per AAA's national gas price table. https://gasprices.aaa.com/state-gas-price-averages/
- [2026-09-25] AAA's historical "highest recorded average price" field lists diesel's all-time record as $6.5276 set on 9/22/26 — meaning the series has never approached $7.00 in AAA's recorded history (dating to at least 2000s), and the prior record before this year's surge was $5.8159 (6/19/22). https://gasprices.aaa.com/
- [2026-09-04] Diesel first broke its 2022-era record, reaching
a new record high of $5.85 as of Sept. 4, 2026, beating the prior record from June 2022
, driven by the Iran war/Strait of Hormuz closure.
- [2026-09-11] Diesel then
surpassed $6 for the first time, standing at $6.06
, which was
the third time in a week diesel has set a record, according to GasBuddy
. https://www.cbs8.com/article/news/nation-world/national-average-diesel-gas-gallon-record-aaa-gas-buddy/507-bcc352cf-4073-4681-9cfe-68fa1e1b23c9
- [2026-09-11] For historical context,
one year ago, AAA reported the national average price for a gallon of diesel was around $3.70
— this year's spike is unprecedented in speed and magnitude versus the historical base rate of gradual, seasonal diesel-price moves.
- [2026-09-09] EIA's September STEO (the most authoritative near-term forecast)
forecasts U.S. retail diesel prices to average $5.55 per gallon (gal) in 4Q26
— a quarterly average well below $7.00, implying the base-case outside view does not expect diesel to reach $7 by early November.
- [2026-09-09] EIA also expects continued supply tightness:
EIA expects constraints on traffic through the strait will continue through the fourth quarter of 2026 (4Q26), leaving an average of 5.7 million barrels per day (b/d) of crude oil production shut in during the quarter
, but this is already priced into current elevated diesel levels rather than implying further sharp escalation to $7.
- [2026-09-09] Global crude assumptions underlying the diesel forecast:
Global oil prices rose in August, with the Brent crude oil spot price averaging $91 per barrel (b), $7/b higher than in July
, and
EIA forecasts Brent to average around $90/b in 2H26 before declining to an average of $74/b in 2027 as oil production recovers and inventories rebuild
— i.e., crude is expected to plateau/ease, not spike further.
- [2026-09-2x] A specialized diesel-market analysis notes structural upside pressures beyond the Hormuz closure:
Three of Russia's largest refineries cut diesel output, September 15, 2026
, and separately
Iran's foreign minister said on September 13 that reopening depends on U.S. compliance with the terms of the expired Islamabad memorandum
, indicating no near-term resolution catalyst for lower prices, but also no acceleration toward $7 in the data cited.
- [2026-06-11] A policy explainer on the diesel spike states
The Strait closure took 14 million b/d off the market: That's roughly 14% of projected 2026 global supply—sending diesel up 58% and jet fuel up 106% year-over-year
, and warns
relief will be slow even after fighting stops: the EIA expects that restarting production and refining will take months. Elevated diesel and jet fuel prices could persist well into the recovery
— supporting a "stays elevated/plateaus" base case rather than a further rapid climb.
- Historical base rate: no comparable "AAA diesel above $7.00" event has occurred at any point in AAA's tracked history (previous all-time record was $5.8159 in June 2022, before this year's war-driven spike to a new record of $6.5276 on 9/22/26). The current episode is itself the extreme tail of the historical distribution, and even this record episode has only reached ~93% of the $7.00 threshold.
BOTTOM LINE: The outside view strongly favors "No": diesel has never in AAA's recorded history reached $7.00 (current all-time record is $6.53, set 9/22/26, and the price has been essentially flat-to-slightly-declining in the most recent daily readings), and the leading independent forecaster (EIA STEO, Sept. 2026) projects diesel averaging $5.55/gal in Q4 2026 — well below $7. A move from ~$6.50 to above $7.00 within roughly five weeks would require a fresh, larger supply shock than any seen even during the peak of the 2026 Iran war/Hormuz crisis.
NOT FOUND: A specific Kalshi or other prediction-market implied probability for this exact contract; a complete week-by-week AAA diesel time series for late September–November 2026 (only spot daily/weekly snapshots were available); any analyst forecast explicitly modeling diesel reaching $7.00 by November 3, 2026.
report: yes case
**Strongest evidence-backed path to YES: extrapolation of the current record-setting rate of increase, combined with confirmed non-resolution of both root supply shocks (Russian refinery strikes and Strait of Hormuz constraints) through at least November.**
- [2026-09-15] A refining-economics deep-dive computed that
Brent averaged $71 in February 2026 and $111.83 in the week of September 11
, and separately calculated that in the week of September 14
the three scenario paths differ by a penny in October and about 50 cents in November, and separate in earnest only from December
— i.e., even under this analyst's framework, November is the first month where a "disruptions continue" path meaningfully outpaces the others, which is the direction needed for a YES resolution. https://agricultural.substack.com/p/the-diesel-forecast
- [2026-09-21] The same analysis notes the diesel futures curve on September 15 implied a Gulf Coast refining margin of $2.58/gal for October, and reading the curve as a market-weighted forecast, "the curve would put roughly a 60 percent weight on the disruptions continuing through spring" — meaning the market itself assigns majority odds to the shock persisting past the Nov 3 deadline rather than reversing. https://agricultural.substack.com/p/the-diesel-forecast
- [2026-09-05] Eurasia Group's Gregory Brew told Fortune the refining-driven price pressure "is likely to come in mid-September and it's going to last through November" — a named analyst explicitly forecasting the pressure window to extend past the Nov 3 deadline, not resolve before it. https://fortune.com/2026/09/05/overlooked-russia-ukraine-war-outsized-impact-energy-diesel-high/
- [2026-09-21] Bloomberg reported Russia is set to extend its diesel export ban beyond September 30, with a source saying the extension could run "for another month or maybe even more" — implying the ban (removing ~10% of global seaborne diesel supply) plausibly persists through the Nov 3 window rather than lifting in time to relieve prices. https://www.bloomberg.com/news/articles/2026-09-21/russia-set-to-extend-diesel-export-ban-beyond-end-of-september
- [2026-09-15] Reuters (via Meduza) confirmed that three of Russia's six largest diesel-producing refineries — Kirishi (fully shut), Volgograd and NORSI (each near 25% capacity) — had cut or halted output, showing the Russian-side supply shock is not marginal but affects roughly half of Russia's diesel production capacity. https://meduza.io/en/news/2026/09/15/reuters-three-of-russia-s-largest-oil-refineries-cut-diesel-output-after-ukrainian-strikes
- [2026-09-15] Despite a Trump-announced Russia-Ukraine energy truce claim on September 14, the same source material notes Ukraine struck the Syzran refinery that same night, and neither government confirmed the truce — evidence that the refinery-strike driver of the price spike has not actually de-escalated. https://agricultural.substack.com/p/the-diesel-forecast
- [2026-09-22] A Crux Investor analysis states that even under an EIA framework assuming Gulf export constraints last through year-end, "Refiners keep diesel cracks the EIA expects to stay above $2 per gallon through November" — a direct, dated EIA-linked projection of continued extreme refining margins spanning the market's exact resolution date. https://www.cruxinvestor.com/posts/hormuz-deal-would-hit-crude-producers-before-it-ends-the-diesel-shortage
- [2026-09-22] The same piece notes that even a reported Iranian offer to reopen the Strait within seven days would not restore Russian volumes, and "US refineries, at 97% utilization in the week ending 11 September (EIA), have almost no spare capacity to cover it" — meaning even a partial resolution on one shock leaves the market with no slack to absorb it, supporting continued upward price pressure. https://www.cruxinvestor.com/posts/hormuz-deal-would-hit-crude-producers-before-it-ends-the-diesel-shortage
- [2026-09-21] Trend arithmetic: AAA's own data (per colleagues' reports) shows diesel rose from $5.85 (Sept 4) to roughly $6.50 (Sept 25), a pace of about 3 cents/day over three weeks; a Yahoo Finance market piece explicitly flags that "speculation around diesel's push toward $7 per gallon remains active among some analysts, given that the disruption to global oil and refining flows persists," showing $7 is already a live analyst discussion point, not a fringe idea. https://finance.yahoo.com/energy/articles/diesel-price-predictions-much-higher-161226017.html
- [2026-09-09] GasBuddy's Patrick De Haan was quoted saying the national average diesel price "could top $6 per gallon within the next week or so" just before it did so — establishing that short-horizon analyst calls on this spike have tended to be directionally correct and arrive quickly, which supports taking further near-term escalation calls seriously. https://www.axios.com/2026/09/09/energy-department-hikes-2027-diesel-price-outlook
- [2026-09-01] Mechanism: the U.S. Gulf Coast diesel crack spread hit record levels near $100-107/barrel in August-September per multiple outlets (dieselnet.com, ttnews.com), a fivefold-plus jump versus a normal $20-30/barrel spread, meaning the entire recent multi-dollar rise in retail diesel has been margin-driven rather than crude-driven — a mechanism that is structurally slower to unwind (refinery repairs take months) than a crude price shock. https://dieselnet.com/news/2026/08diesel-crack.php
BOTTOM LINE: The single most credible mechanistic path to YES is continuation of the same refining-margin-driven rate of increase seen since September 4 (~3 cents/day), which if sustained through November 3 would push the national average well past $7; this is reinforced by dated, named-source forecasts (Eurasia Group's Brew, EIA-linked crack-spread projections through November, and a possible Russian export-ban extension "through the end of the year") that explicitly place the disruption's duration past the market's Nov 3 deadline, and by a diesel-futures curve that a quantitative model reads as assigning roughly 60% weight to the shock continuing through spring 2027.
NOT FOUND: No source gives a specific point-price forecast for diesel on November 3, 2026 itself, nor any analyst who explicitly forecasts crossing $7.00 by that date (only "speculation... remains active among some analysts" toward $7, without a date or probability attached); no confirmation that the Trump-claimed Sept. 14 energy truce has broken down entirely versus partially holding.
report: no case
- [2026-09-25] Wholesale/rack diesel — the leading indicator for retail AAA prices — fell sharply in the same week AAA's retail average was flat:
Diesel prices faced downward pressure during the week, with only a brief uptick on Wednesday, falling from $5.1142 on Monday to $4.7850 on Friday, the lowest level of the period, a decline of about 6.4% for the week
. This is a rack-price reversal that typically feeds into retail averages within one to two weeks, arguing against a further climb toward $7.00.
- [2026-09-25] Crude itself fell hard mid-week before only a partial recovery:
Prompt WTI futures were down more than $2 per barrel this morning and on track to decline roughly $3 per barrel week over week, with Brent trading near $105 and WTI around $93
. A daily breakdown shows
crude opening at $101.00 on Monday, falling to $89.89 by Wednesday (the week's low) before a partial rebound to $94.75 by Friday, a net decline of about 6.2% for the week
— the opposite of the acceleration a Yes resolution would require.
- [2026-09-25] Diplomatic progress toward reopening Hormuz is real, not merely rumored: Iran has offered a concrete, dated proposal.
Iran has offered to reopen the Strait of Hormuz and resume talks on its nuclear program in seven days if the United States lifts its naval blockade, waives sanctions on Iranian oil sales and observes a ceasefire that would include Lebanon
, and
the White House said officials are having positive and constructive conversations with mediators on the Iran war, and is facilitating significant oil exports through the Strait of Hormuz
.
- [2026-09-25] History argues for caution on how fast any deal materializes — a nearly identical proposal already failed once:
the proposal conveyed to the U.S. by mediators strongly resembles the memorandum of understanding reached in June, but with an accelerated timetable — and the earlier agreement, which called for a 60-day interim period, quickly collapsed as Iran resumed attacks on shipping in the strait
. This "deal-then-collapse" pattern cuts both ways, but it also means a durable price-crushing resolution before Nov 3 is not guaranteed, tempering (not reversing) the case for continued escalation to $7.
- [2026-09-25] Physical Hormuz flows are already improving marginally even absent a final deal:
crude exports through the strait reached 33.7 million barrels so far this week, roughly in line with the previous week's pace
, and Saudi Arabia is actively working around the bottleneck —
Saudi Arabia has increased crude movement through its East-West Pipeline toward the Red Sea
— both incremental supply-side reliefs rather than further tightening.
- [2026-09-23] EIA's own near-term modeling implies a plateau, not an acceleration:
the agency forecasts that the U.S. average diesel crack spread will stay above $2 a gallon through November before declining steadily through mid-2027
. A crack spread that is merely "staying" flat through the market's expiration window — rather than widening further — is inconsistent with a roughly 8% additional retail jump (from ~$6.50 to $7.00) in five weeks.
- [2026-09-25] Even a bullish, refining-focused analysis frames the crude leg of the current price spike as reversible on a single headline:
the crude leg of this trade can be erased by a ceasefire headline, and Iran said this week that a Hormuz transit arrangement with Oman is days away
(writing from three weeks prior, showing this reopening narrative has recurred repeatedly without yet delivering the sustained escalation needed to hit $7).
- [2026-09-25] A newly floated U.S. policy lever could cut the opposite way from a Yes case, but its net effect is ambiguous/bearish for near-term escalation risk being the *sole* driver:
the Trump administration continues to examine whether a full or partial restriction on diesel exports could help reduce domestic fuel prices
, meaning policymakers are actively targeting the exact price the market is testing, adding downside policy risk to the "further $7 spike" scenario.
- [2026-09-23] Independent trucking-industry data corroborates that the rate of increase has been slowing/plateauing at the national level even as regional extremes (e.g., California) diverge:
the national average on-highway diesel price rose 24 cents to $6.529, according to EIA data released on September 22
, but a competing report the same week noted
the national average for diesel stood at $6.52 on Wednesday after dipping by one cent overnight
— i.e., the all-time-record run has already begun to stall around $6.50–$6.53 rather than continuing a steep linear climb.
- [2026-09-25] Even the most price-alarmed commentary anchors current pain at $6.50, not near $7:
"Brent at $100 and diesel at $6.50 a gallon are already squeezing consumers," said Rystad Energy's chief economist, warning the energy shock could tip into an economic slowdown
— no analyst quoted in current reporting frames $7.00 as an imminent or expected near-term threshold.
BOTTOM LINE: The most recent (Sept. 22–25) data shows crude prices falling, wholesale diesel dropping ~6.4% in a single week, a concrete (if fragile) Iranian reopening offer on the table, and EIA's own crack-spread forecast implying a plateau rather than further escalation through November — all pointing to diesel stalling near its current ~$6.50 record rather than climbing another ~$0.50/gal (nearly 8%) to clear $7.00 by November 3.
NOT FOUND: No evidence of any specific catalyst (new attack, export ban implementation, or supply shock) currently priced by markets that would push diesel from ~$6.50 to above $7.00 within the remaining five weeks; no confirmation of whether the September 25 Iranian seven-day reopening offer has been accepted or rejected by the U.S. as of the report date.

(0) The condition is not met yet. AAA's resolution page shows diesel at $6.4839 on 9/26/26, below the all-time record of $6.5276 set on 9/22, so the price would need to rise about 8% more by November 3. (a) About 38 days remain until the single-day AAA reading on November 3. (b) If nothing changes, diesel stays near $6.45–6.50 and the market resolves No. The latest daily readings are drifting down from the peak: $6.53, then $6.51, $6.50, $6.48. (c) NO scenario: rack diesel's roughly 6.4% weekly drop (to $4.79) and crude's roughly 6% decline feed into retail over the next one to two weeks. Iran's seven-day Hormuz reopening offer or a possible US diesel export restriction then lowers prices, and diesel ends near $6.00–6.40. (d) YES scenario: the Hormuz talks collapse again, as the June MOU did. Russia extends its export ban and Ukrainian refinery strikes continue, crack spreads widen further, and the early-September pace of about 3 cents a day resumes, pushing diesel past $7. In a crisis-volatility regime, an 8% move in five weeks is roughly a one-sigma event, but the drift now looks negative. The code-execution output started from a wrong price ($3.77) and should be ignored. The Kalshi anchor is 15–18%. The fresh wholesale and crude declines point to a plateau or reversal, so I shade slightly below the market while keeping real jump risk for a renewed escalation.

(0) Not resolved. AAA's resolution page shows diesel at $6.4839 on 9/26/26, off its all-time record of $6.5276 set on 9/22. Diesel would need to rise another ~8% and be above $7.00 on the single Nov 3 reading.
(a) About 5.5 weeks remain until the Nov 3 value.
(b) If nothing changes, diesel stays around $6.45–6.50, well below $7.00, so the market resolves No.
(c) NO scenario: The last week points to a stall.
- Wholesale/rack diesel fell ~6.4% in one week, to about $4.79.
- Brent dropped from ~$131 (9/15) to ~$105–115, and WTI fell to the low $90s.
- Iran floated a seven-day Hormuz reopening offer.
- EIA projects crack spreads merely holding above $2/gal through November, and forecasts a 4Q26 diesel average of $5.55.
Retail diesel lags wholesale, so these signals point to a drift lower into October.
(d) YES scenario: A new shock pushes prices higher again, such as the Hormuz deal collapsing (as the June MOU did), fresh Ukrainian strikes on Russian refineries, or Russia extending its diesel export ban. With refineries at ~97% utilization, the September pace of ~3¢/day could resume. That would clear $7 by early November.
Market and model: The Kalshi anchor is 18% (bid 15%/ask 18%, last close 15%). The code-execution output is invalid because it assumed a $3.65 starting price. A crisis-regime volatility of ~4% weekly gives roughly a 20% chance with no drift. The fresh wholesale and crude declines imply negative near-term drift that the market's ask may underweight. I shade slightly below the market, to about 12%.

(0) The condition has not already been met: AAA’s resolution page shows diesel at $6.4839 on September 26, below $7.00, and resolution requires AAA’s November 3 value to exceed that threshold. (a) About 38 days remain, during which diesel must rise by roughly $0.52, or 8%, from today’s level. (b) If current conditions merely persist, the recent plateau near $6.50 and falling wholesale diesel prices imply a No outcome. (c) No results if lower rack and crude prices feed through to retail, refining margins stabilize, or Hormuz diplomacy produces even partial supply relief. (d) Yes remains plausible if unresolved Hormuz constraints, Russian refinery outages and export restrictions produce another leg of the September surge, since sustaining the earlier roughly three-cent-per-day rise would clear $7 before November 3. I anchor on Kalshi’s 18% Yes price but move modestly to 16% because the latest wholesale diesel decline of about 6.4%, the stalled AAA readings, and EIA’s plateau-oriented outlook slightly outweigh the persistence of the supply shock.

(0) The condition is not already met: AAA’s resolution page showed diesel at $6.4839 on September 26, below $7.00, and only AAA’s November 3 value will resolve the market. (a) About 38 days remain, during which the AAA average must rise by more than $0.516, or roughly 8%, to produce Yes. (b) If the current level and recent plateau persist, the status quo outcome is No. (c) No results if declining wholesale diesel and crude prices feed through to retail prices, or if improving Hormuz flows, diplomacy, or policy intervention eases the supply shock; the EIA’s $5.55 fourth-quarter average forecast and the recent $6.5276 peak support this scenario. (d) Yes results if unresolved Hormuz constraints, Russian refinery outages and an extended export ban renew the roughly three-cent-per-day September climb, with already extreme refining margins providing a credible mechanism. I anchor on Kalshi’s 18% Yes price but reduce it modestly to 16% because the latest leading indicators show wholesale diesel falling about 6.4% and AAA prices flattening, while disregarding the code model’s near-zero estimate because it incorrectly used a roughly $3.77 starting point rather than the documented $6.48 level.
