Speedway Motorsports
Speedway Motorsports, LLC is an American company that owns and manages auto racing facilities. The company was founded by Bruton Smith and is headquartered at Charlotte Motor Speedway in Concord, North Carolina, just north of Charlotte. Speedway Motorsports owns 11 racing facilities across the United States. In addition to operating racetracks, the company owns the Performance Racing Network (PRN) and U.S. Legend Cars International, and co-owns Motorsports Authentics. As of 2026, it owns the second-most racetracks used by NASCAR, behind only NASCAR itself. After trading for 25 years on the New York Stock Exchange as Speedway Motorsports, Inc. (SMI; formerly NYSE: TRK), the company was taken private in September 2019. It is a wholly owned subsidiary of Sonic Financial Corporation, an entity controlled by members of the Smith family. The initialism remains in common colloquial use.
