Costco Wholesale reported record-breaking volumes for gasoline in its fiscal third quarter of 2026, driven by rising fuel prices. The company's CEO, Ron Vachris, stated that the final five weeks of the quarter, which ended on May 10, 2026, were Costco's top five volume weeks ever for gasoline.
The strong gas sales contributed to the company's overall performance, though specific financial details for the quarter were not disclosed in the initial report. Costco's gas stations are known for offering competitive prices, which likely attracted more customers during the period of higher fuel costs.
This achievement highlights Costco's ability to leverage its membership model and operational efficiency to drive volume even in challenging market conditions. The company continues to expand its footprint, with new warehouse openings planned for the coming months.
