Speedway is a wholly owned subsidiary of Marathon Petroleum.
Speedway began as Speedway 79, a Michigan based gas station chain.
In 1959, the company was purchased by the Ohio Oil Company (now Marathon) and all stations were converted to Marathon brand.
Speedway and SuperAmerica were combined in 1998 when Marathon and Ashland merged.
In 2003, the company launched the Speedy Rewards program.
In 2011, Marathon sold SuperAmerica. The two chains are now unrelated.
In 2012, the company acquired GasAmerica and all 88 of their stations in Ohio and Indiana.
In 2014, the company acquired Hess Corporation for $2.6 billion, adding an additional 1,342 locations to Speedway. Most of the Hess locations are being changed to the Speedway brand. 
Today, there are nearly 3,000 Speedway gas stations in Ohio, Michigan, Indiana, Illinois, Kentucky, Pennsylvania, Tennessee, West Virginia, and Wisconsin, making it the second largest chain of gas stations/convenience stores in the US.
Speedway is now owned by 7-11, who acquired the chain in 2021 and immediately cut jobs
In a classic scam, consumers should be aware that Speedway is not selling $500 gas cards for $1.98.
