Costco Wholesale Corporation COST continues to show its ability to attract members to its warehouses, with its second-quarter fiscal 2026 results reflecting a strong rise in comparable sales. Total company comparable sales increased 7.4% for the 12 weeks ended Feb. 15, 2026. When adjusting for the effects of gasoline prices and foreign exchange rates, comparable sales still remained solid at 6.7%. Traffic growth remains one of the key drivers of this performance.
Worldwide comparable traffic or shopping frequency grew 3.1% during the quarter. This growth was consistent across all geographic regions, with the United States experiencing a 2.4% increase in traffic, while Canada and other international markets saw even higher gains of 4.3% and 4.6%, respectively.
The average transaction amount, or ticket size, also played a role in overall sales performance. Globally, the average ticket rose 4.2%, or 3.5% when adjusted for gasoline prices and currency fluctuations.
Traffic increases seem closely linked to ongoing improvements in the shopping experience. Initiatives such as mobile wallet upgrades, pharmacy pay-ahead, employee pre-scan technology, and a pilot automated pay station are helping improve traffic flow and enhance the member experience.
From a growth perspective, the balance between traffic and ticket size is noteworthy. While the average ticket increased, the rise in visit frequency indicates that comparable sales are being driven significantly by higher member engagement. This demonstrates Costco’s ability to stay relevant and encourage repeat visits through value and product assortment.
