AAA's national average diesel price topped $5.90 a gallon by September 9, 2026, extending a string of records that began earlier in the month. The average had already hit $5.85 on September 4, its first new high since 2022, before climbing further amid tight supply tied to disruption in regional oil markets connected to the Iran conflict, according to Fox Business. By September 10, AAA put the national average at $5.97, while GasBuddy, which tracks prices in real time, reported diesel crossing $6 a gallon nationally for the first time ever. It marked the third time diesel prices set a record within a single week, with several states, including Arkansas and Missouri, reporting all-time highs of their own. Diesel's climb has drawn attention because it feeds directly into freight and shipping costs, pressuring prices for goods that depend on trucking. Community bettors correctly anticipated the trend, with 67% predicting the national average would clear $5.90, matching the rapid pace of increases already visible in the data heading into resolution. The run of records reflects an unusually volatile stretch for fuel markets tied to geopolitical tensions in the Middle East.
