Alaska diesel prices in Sep 2026
Short Answer
Alaska diesel prices are likely to settle above $6.6000 per gallon by September 30, 2026, as the average price was reported at approximately $6.66–$6.68 per gallon on September 24, 2026; the market prices this outcome at 65.0%.
1. Market Behavior & Drivers
No specific news event or data release corresponds with the major price swings in this market during late September. The provided research does not identify a catalyst for the 76.0 percentage point spike on September 25, nor for the 17.0 percentage point drop two days later. The market's movement appears disconnected from a specific, identifiable trigger.
The fundamental price environment was, however, highly volatile. Alaska's statewide average diesel price surged to a record high of approximately $6.68 per gallon by September 24. This represented a significant increase from $5.54 a month earlier. This price level put the market on a knife's edge relative to a $6.70 threshold, which may explain sharp fluctuations in sentiment even without a discrete news driver.
- Alaska diesel prices exceeded $6.60 per gallon as of September 24, 2026.
- Prices were near $6.66–$6.68, and strong upward momentum suggests breaching $6.70.

Current Context
Alaska diesel prices surged to record levels by late September. As of September 24, 2026, Alaska's average diesel price was $6.680 per gallon, including $0.089 state tax and $0.244 federal tax [1]. A separate September 22 source reported $6.663, indicating a statewide level between $6.66 and $6.68 immediately before September 30 [1][2]. Diesel prices climbed significantly during September; AAA's Alaska average reached a record $6.68 per gallon by September 24, up from $5.54 a month earlier and $4.08 a year earlier [3]. Fairbanks recorded a record $6.70 on September 20, compared to $4.17 a year earlier [4]. The U.S. national diesel price reached $6.529 per gallon for the week ending September 21, 2026 [5]. Alaska is part of the PADD V (West Coast District) for energy reporting, which recorded a monthly diesel sales price of $6.254 per gallon in August 2026 [6][7].
Refined-fuel margin widening and supply constraints drove price increases. The main economic driver was a sharp widening in refined-fuel margins [3]. The EIA attributed tighter diesel and heating-oil markets to refinery disruptions in Russia, China, and the Middle East, along with reduced U.S. imports and stronger foreign demand [3]. Its September forecast raised the 2026 diesel/heating-oil spread from $1.30 to $1.57 per gallon [3]. Alaska faces additional logistical exposure; western communities depend on a single May–October maritime resupply window, and 2026 reports cited credible risks that global supply constraints, tanker scarcity, and Middle East conflict could delay or reduce deliveries, especially for remote communities [3][8]. On September 22, Senator Dan Sullivan called for a temporary U.S. diesel-export moratorium until the Iran conflict ends and Strait of Hormuz energy flows normalize [9]. An earlier July 17 emergency EPA waiver relaxed sulfur requirements for qualifying Arctic-grade diesel above the Arctic Circle [9]. Crude oil spot prices also experienced volatility in mid-September, with WTI fluctuating around $96-$107 per barrel and rising over 4.3% in a single day to exceed $105 per barrel, driven by global conflict and supply constraints [10][11].
Prediction markets strongly favored elevated Alaska diesel prices for September 30. Kalshi-derived odds showed 94% for above $6.40 as of September 26, while Parity showed 88% for above $6.00 and only about 12.5% for above $6.70 [12][13]. Related September 30 oil markets were mixed but generally elevated; Gemini showed an 88% probability for WTI at or above $84 as of September 27 [14]. ForecastEx showed a 64% probability that WTI would not exceed $94 [15]. Manifold showed roughly 72–75% probability that Brent would not settle at or above $100 [16][17]. The best evidence-based point forecast for Alaska's September 30 statewide diesel average is approximately $6.65–$6.75 per gallon, with the central estimate near $6.68 [1][3][4][12][13]. Upside risk above $6.70 is meaningful, but the market evidence cited assigns only about 12.5% to above $6.70, and remote delivered-fuel prices may differ materially from pump averages [1][3][4][12][13].

Notable price changes detected in the chart, along with research into what caused each movement.
Outcome: Above $6.7000
📉 September 27, 2026: 80.0pp drop
Price decreased from 87.0% to 7.0%
What happened: The provided evidence does not substantiate an 80.0 percentage point drop in the "Alaska diesel prices in Sep 2026" prediction market for the "Above $6.7000" outcome on September 27, 2026 [1][2][3]. Instead, available data for late September 2026 shows increasing national and regional diesel prices, driven by global refinery disruptions and concerns over potential U.S. diesel-export restrictions [4][5][6]. No specific social media activity or traditional news announcement was identified as a catalyst for such a sharp market decline [1][2][3]. Therefore, social media was not a primary driver, as the premise of the market movement itself is unverified.
Outcome: Above $6.9000
📉 September 26, 2026: 11.0pp drop
Price decreased from 22.0% to 11.0%
What happened: No specific social media activity, such as posts from influential figures or viral narratives, was identified as a driver for the 11.0 percentage point drop in the "Above $6.9000" outcome for Alaska diesel prices on September 26, 2026. Traditional news reported that Alaskan diesel prices were at record levels in late September, with the broader U.S. and regional (PADD V) trends showing an upward movement in actual prices leading up to this date [7]. While Senator Dan Sullivan called for a temporary U.S. diesel-export pause on September 22 in response to high prices, the provided sources do not establish a direct causal link between this policy reaction and the reported prediction market probability decline on September 26 [8]. Based on the available information, social media appears to have been irrelevant to this specific prediction market movement.
Outcome: Above $6.6000
📈 September 25, 2026: 76.0pp spike
Price increased from 6.0% to 82.0%
What happened: The provided research does not identify a specific cause for a 76.0 percentage point spike in the "Alaska diesel prices in Sep 2026" prediction market on September 25, 2026, nor can the spike itself be independently validated from the curated sources [3][9][1][10][2][11]. Alaska's statewide average diesel price was already above $6.60 per gallon by September 20–22, reaching $6.68 by September 24, driven by global refinery disruptions, reduced U.S. imports, and the Iran conflict [7][4][12][13]. No social media activity was found to be a catalyst for the alleged prediction market movement [13][8]. Therefore, social media was irrelevant, as the underlying price movement preceded the alleged market event and was driven by traditional economic and geopolitical factors [4][13][8].

Market Discussion
Alaska diesel prices reached a record statewide average of $6.12/gal by September 8, 2026, with AAA's statewide average later cited at $6.68/gal on September 24, 2026 [1]. A prediction market contract on September 26, 2026, reflected a 94% probability of prices finishing above $6.40 [2], with analysts attributing elevated prices to global refinery disruptions, reduced U.S. imports, stronger foreign demand, and constrained inventories [3].

6. What was the market impact of Senator Dan Sullivan's proposed diesel export moratorium and the EPA's fuel waiver in September 2026?
| Sullivan Proposal Status | Not enacted as of September 22–23, 2026 [1][2] |
|---|---|
| EPA Waiver Effective Period | September 15–October 4, 2026 [3][4] |
| EPA Waiver Geographical Scope | Only Alaska north of the Arctic Circle [3][4] |
Alaska's September 2026 diesel market saw continued high prices. Prediction market evidence indicated continued elevated prices rather than a clear policy-driven collapse [5][6]. Senator Dan Sullivan's proposed diesel export moratorium, announced on September 22, 2026, was a proposal and not enacted into policy [1][7][2]. This proposal was expected to create short-term price volatility and a bullish or uncertain signal for Alaska prices, rather than immediate relief [7][5].
EPA's emergency fuel waiver had a narrow, limited impact. The EPA's emergency fuel waiver, renewed on September 8 and effective from September 15 to October 4, 2026, had a targeted and narrow scope [3][4]. It applied only to Alaska north of the Arctic Circle and permitted qualifying older vehicles and nonroad equipment to use diesel with up to 5,000 ppm sulfur [3][4]. While this waiver could improve local fuel availability by potentially unlocking 75,000 gallons per day of locally produced diesel, its limited geographical and technical scope, combined with logistics constraints, restricted its overall effect on statewide September average prices [3][5][4][8].

7. How did the EIA's fuel margin forecasts for September 2026 and AAA's price data support a settlement near $6.70?
| Alaska Diesel Price (September 2026) | $6.6653 per gallon (AAA, September 21, 2026) [1] |
|---|---|
| Market Implied Settlement | Near $6.70 (September 26) [2][3] |
| EIA 2026 Distillate Crack-Spread Forecast | Raised to $1.57 per gallon (from $1.30) [4] |
Market expectations and AAA data supported a $6.70 Alaska diesel settlement. The market anticipated Alaska diesel prices would exceed $6.445 by September 26, aligning with an estimated settlement near $6.70 [2][3]. This expectation was reinforced by AAA's data from September 21, 2026, which reported the Alaska state-average diesel price at $6.6653 per gallon, effectively $6.70 [1].
EIA significantly revised its fuel margin forecasts upward for 2026. The Short-Term Energy Outlook (STEO) from the EIA on September 9, 2026, significantly increased its 2026 distillate crack-spread forecast by 20.8%, raising it to $1.57 per gallon from $1.30. Concurrently, the EIA also raised its 2026 U.S. retail diesel forecast by 4.4%, moving it to $5.07 from $4.85 [4]. This upward revision was attributed to elevated petroleum-product crack spreads and crude prices influencing retail fuel costs, as detailed in an EIA analysis from September 4 [5].
EIA's inventory outlook further indicated sustained high diesel prices. The EIA's outlook projected that U.S. distillate inventories would drop below 100 million barrels in September and remain below the 2021–2025 five-year low throughout much of 2027. Global distillate production is also projected to stay below the previous year's levels, which is expected to support persistently high diesel prices [4]. Therefore, the market-implied settlement near $6.70 is supported by both AAA's direct observation for Alaska diesel and the EIA's revised outlook on margins and inventories [6]. It is important to note that the EIA's $5.07 forecast applied to national retail diesel prices, not specifically to Alaska [6].

8. How did the September 2026 diesel price surge in Alaska compare to the U.S. national average and the PADD V (West Coast) region?
| US National Diesel Average (Sept 7, 2026) | $5.967 per gallon [1] |
|---|---|
| PADD V Diesel Average (Sept 7, 2026) | $6.987 per gallon [1] |
| West Coast Premium over US Average (Sept 7, 2026) | $1.020 per gallon [1] |
Alaska's September 2026 diesel price data is unavailable for comparison. The available research does not provide a directly verifiable September 2026 Alaska retail diesel average, making an exact comparison to U.S. national and PADD V figures impossible [2][3][4][5][6][7]. Contemporaneous search results confirm September 2026 as a period of broad national diesel surge, but specific Alaska price data was not found in updated state price pages, prediction market results, or EIA series for that month [2][8][9].
National and West Coast diesel prices surged significantly in early September 2026. On September 7, 2026, weekly on-highway diesel averages reported by the EIA were $5.967 per gallon nationally and $6.987 per gallon for PADD V (West Coast), indicating a $1.020 per gallon West Coast premium [1]. During the period between August 24 and September 7, 2026, the U.S. average increased by $0.315 (5.6%), while PADD V experienced a larger surge of $0.580 (9.1%) [1]. This demonstrates the West Coast increase exceeded the national trend in both absolute and percentage terms [1].
California's high prices significantly influenced the PADD V average. The absence of specific September 2026 Alaska retail diesel prices means an exact comparison with the U.S. and PADD V averages cannot be established [3][4][5][6][7]. California's price of $7.764 significantly influenced the overall PADD V average of $6.987, as the West Coast excluding California stood at $6.314 on September 7, 2026 [1]. For a prediction market resolving September 30, 2026, the available evidence supports conclusions about national and PADD V prices but not a definitive numerical forecast for Alaska diesel prices [1][9].

9. What daily or weekly datasets from the EIA and AAA were available to track Alaska's diesel price movements in the final weeks of September 2026?
| Primary Daily Alaska Diesel Price Source | AAA Fuel Prices (September 2026) [1] |
|---|---|
| EIA Alaska Daily/Weekly Diesel Data | Not available for late September 2026 [2][3][4][5][6][7] |
| Prediction Market Settlement Source | AAA for September 27, 2026 observation [8][1] |
AAA Fuel Prices provided daily Alaska diesel prices for late September 2026. This near-real-time source effectively monitored Alaska's diesel price movements during the final weeks of September 2026 [1]. The state-level diesel price tracker specifically included Alaska in its daily state-average table, reporting the state's diesel price alongside gasoline grades [1][9]. Further supporting its operational value, a prediction market listing cited AAA as its settlement source and referenced a September 27, 2026 diesel price observation [8][1].
The EIA did not offer Alaska-specific daily or weekly diesel price data. The U.S. Energy Information Administration (EIA) did not have Alaska-specific daily or weekly diesel price datasets available for the final weeks of September 2026 [2][3][4][5][6][7]. While the EIA offered Alaska-specific diesel price datasets, these were monthly, such as the Alaska No. 2 diesel/No. 2 distillate retail prices by sales type [2][3][4][5]. The historical series release metadata for these monthly datasets, indicating a June 1, 2022 release and a 'To Be Determined' next release date, rendered them unsuitable for a daily or weekly tracker in late September 2026 [2][3][4][5]. Additionally, the EIA's weekly on-highway diesel survey explicitly excluded both Alaska and Hawaii from its PADD 5 series [6]. The EIA's broader data catalog provided monthly, annual, and historical downloadable price data, but no evidence indicated the availability of an Alaska-specific daily or weekly EIA diesel price series during the specified period [7][2][3].

10. How did crude oil forecasts on other prediction markets, like Gemini and Manifold, align with the implied costs in Kalshi's Alaska diesel market?
| Brent Crude Price (Manifold, Sep 2026) | Around $95 [1][2][3] |
|---|---|
| WTI Crude Price (Manifold, Sep 2026) | Around $91 [1][2][3] |
| Probability of Brent ">= $100 (Manifold, Sep 30) | 72% [2] |
A direct quantitative comparison of crude and diesel markets is currently unfeasible. A direct quantitative comparison between crude oil forecasts from prediction markets like Gemini and Manifold and the implied costs in Kalshi's Alaska diesel market is not possible with the available information [1][2][3][4][5][6]. While an overall directional alignment could be assessed, numerical forecasts from Gemini cannot be reliably extracted from the available evidence because the retrieved pages for its WTI crude-price event markets for September 28 and 30, 2026, do not provide odds or strike distributions [4][5][7].
Manifold markets project an elevated crude oil price outlook. These markets presented a broadly elevated crude outlook, with one market indicating Brent around $95 and WTI around $91 for September 2026 [1][2][3]. Another Manifold market assigned a 72% probability to Brent settling at or above $100 on September 30 [2]. Additionally, a third market treated a WTI close at or below $65 before October 1 as a contested downside, not a consensus outcome [3]. This collective information suggests crude is expected to remain near or above approximately $90-$100 through September 30, according to Manifold [1][2][3].
Kalshi's Alaska diesel market lacks specific pricing data. For Kalshi, a September 2026 Alaska-diesel listing exists, but the retrieved aggregator result does not show the market's strike ladder or current prices [6]. It is important to note that the displayed 99% figure pertains to a different 'Diesel prices tomorrow' contract, which resolves on September 27, and is not relevant to the September 30 Alaska market [6]. Consequently, a quantitative comparison to Kalshi's Alaska-diesel implied costs is not supported by the retrieved information [1][2][3][4][5].

11. What Could Change the Odds
Key Catalysts
Alaska retail diesel prices exhibited substantial upward momentum into late September, with statewide averages and Fairbanks reaching records near $6.62211$6.70/gal between September 2421126, 2026, significantly higher than the $4.08211$4.17 range a year prior [1][2][3][4][5]. Prediction markets for the September 30 Alaska settlement indicated a 94% probability above $6.40 and 84% above $6.30, though the $6.50 threshold was less certain at approximately 42% [4][5]. This bullish pressure derives from multiple supply-side factors, including global refinery disruptions, constrained distillate inventories, reduced U.S. imports, strong foreign demand, and approaching refinery maintenance [2][6][7][8]. The EIA projects U.S. distillate fuel inventories will fall below 100 million barrels in September 2026 and remain below the five-year low through most of 2027, with Brent crude expected to average about $90/b in 2H26 [9][10][11][12][13][14]. Geopolitical risks also contribute, particularly Strait of Hormuz tensions2014Brent crude rose ~2.52114% on September 28 after President Trump rejected Iran's proposal, with managers anticipating oil sustained around $100/b through year-end [4][6][9][10][11][12][13][14]. Furthermore, Russian oil supplies to India are expected to tighten in October and November 2026 due to reduced exports and strong Chinese demand [3][9][10][11][12][13][14].
A primary bearish catalyst would be a U.S. diesel-export restriction, which Goldman-related reporting estimated could lead to an initial U.S. diesel decline of roughly $0.25/gal per week, or about 4% from $6.50 [6][7][8]. However, this restriction is described as plausible but not the base case [6][7][8]. Monetary policy tightening also presents downside risk; the FOMC implemented a 25 bp rate hike on September 1621117, 2026, with the dot plot signaling one to two additional hikes [1][9][10][11][12][13][14]. Elevated rates and a 10-year Treasury yield around 5.21% could dampen demand and eventually cap energy prices [4][6][9][10][11][12][13][14]. Some analysts anticipate global demand will respond to tightening financial conditions, potentially easing upward pressure on final energy prices, with energy-driven inflation pressure possibly abating toward year-end [1][6][9][10][11][12][13][14].
Key immediate event risks include the September 29 EIA Gasoline and Diesel Fuel Update and the September 30 Alaska AAA settlement [6][7][15][16]. Other September 30 releases include BEA's Q2 2026 GDP estimate and August 2026 Personal Income and Outlays, alongside the Dallas Fed Energy Survey [17][18][19]. Stronger economic data or a bullish energy survey could reinforce upward price trends, while weaker figures would be bearish [17][18][19]. The base-case assessment for September 30 suggests a bullish-to-stable bias above $6.40, with $6.50211$6.70 plausible if current refinery and geopolitical tightness persists [2][6][7]. A sharp downside move would most likely require a confirmed export-ban policy, rapid crude/refined-product de-escalation, or evidence that Alaska's elevated prices are catching up downward [2][6][7].
