Cheapest Gas in US Today: Mississippi Leads at $2.68 Amid Deep Regional Divide
As of May 30, 2026, the cheapest gas in US today is found in Mississippi, where the average price for regular unleaded gasoline stands at $2.68 per gallon, according to Forbes Advisor data. The national average sits at $3.17 per gallon, unchanged from yesterday and last week, but the regional imbalance spans over $2.00 per gallon between the cheapest Southern states and the most expensive West Coast markets.
State-by-State Price Rankings: The Bottom 5 Cheapest Markets
Gasoline pricing remains heavily concentrated in the South and Midwest, where refinery capacity, lower shipping costs, and abundant crude supply create persistent price advantages. The five cheapest states for regular gasoline are:
- Mississippi: $2.68/gallon (lowest nationally)
- Oklahoma: $2.72-$2.77/gallon
- Texas: $2.77/gallon
- Arkansas: $2.79/gallon
- Tennessee: $2.77/gallon
These states benefit from proximity to Gulf Coast refineries, which process domestic shale crude at lower marginal costs than West Coast facilities constrained by unique fuel specs and limited supply.
Regional Price Disparities: A $2.20 Per Gallon Gap
The regional imbalance in U.S. gasoline prices reflects structural differences in refining infrastructure, pipeline networks, and state-level regulation. California leads the nation at $4.873/gallon, creating a $2.193 spread versus Mississippi-the widest state-to-state gap in over a decade.
| Region/PADD | Avg. Regular Price ($/gal) | Versus National Average |
|---|---|---|
| Mississippi (South) | $2.68 | -$0.49 |
| Oklahoma/Texas (Gulf Coast) | $2.77 | -$0.40 |
| National Average | $3.17 | - |
| Gulf Coast (PADD3) | $3.328 | +$0.16 |
| West Coast (California) | $4.873 | +$1.70 |
| Hawaii | $4.40-$4.45 | +$1.23-$1.28 |
The data confirms that West Coast prices remain stubbornly elevated due to refinery outages, California's low-carbon fuel standard, and reliance on imported crude.
Why the South Dominates Cheap Gas Markets
The Gulf Coast region produces over 45% of U.S. refining capacity, creating a supply advantage that flows directly to retail pumps in neighboring states. Oklahoma and Texas benefit from Bakken and Permian Basin crude proximity, reducing transportation costs by $0.30-$0.50/gallon versus East Coast markets.
Additionally, the Midwest has seen a shale oil boom since 2012, increasing local supply and moderating prices, though pipeline bottlenecks still prevent full arbitrage to the East Coast. This structural constraint explains why Vermont and New York average $0.40-$0.60/gallon more than Texas despite similar demand profiles.
National Average and Trend Context
The AAA national average for regular gasoline is $3.17/gallon as of May 30, 2026, unchanged from the prior week and up just $0.04 from last month. This represents an 8.3% decline versus September 2024, reflecting eased global crude markets and elevated U.S. refinery utilization rates.
- Week ago average: $3.17/gallon (unchanged)
- Month ago average: $3.13/gallon (+$0.04)
- Year ago (Sept 2024): $3.45/gallon (-8.3%)
- AAA premium grade: $5.237/gallon
- AAA diesel average: $5.492/gallon
These stable national trends mask intense regional volatility, with some West Coast stations exceeding $6.00/gallon during summer driving season.
Implications for LNG Market Participants
While gasoline prices reflect refined product markets, the regional imbalance signals broader energy infrastructure constraints relevant to LNG traders and procurement teams. States with cheap gasoline often have abundant domestic natural gas, supporting LNG export terminal economics on the Gulf Coast.
Global LNG market size reached $153.2 billion in 2025 and is projected to grow to $312.4 billion by 2034 at an 8.6% CAGR, driven by U.S. export capacity expansion. The same Gulf Coast infrastructure that delivers cheap gas to Mississippi also anchors the U.S. LNG export hub, creating integrated supply chain advantages for liquid LNG operators.
