Speedway and Circle K hold the most significant market shares for motor fuel stations and stores in the United States. Both brands generate most of their revenue from fuel sales, with Speedway recording just under seven billion U.S.dollars in fuel sales, and five billion U.S. dollars in merchandise sales. Circle K, under parent corporation Alimentation Couche-Tard, recorded 28 billion in revenue from road transportation fuel sold in the United States and ten billion U.S. dollars in merchandise sales.
Of the leading fuel station brands, Speedway has the most gas stations in the United States, with 2,866 as of 2018. Circle K had almost 4,500 stations in 2017, but that number dropped to 1,625 in 2018.
The brand of motor fuel most frequently sold in the United States is Shell. The United States is a growing source of revenue for Royal Dutch Shell, which had 388 billion U.S. dollars in revenue worldwide in 2018. Other prominent motor fuel brands sold in the United States include Exxon Mobile, Speedway, Chevron, and BP.
Speedway saw a large volume of customers in 2018, the most of any of the top fuel and convenience retailers in the United States. Most people at gas stations pay with their debit cards, perhaps to keep track of their day-to-day expenses.
