The Seattle Mariners are majority owned by John W. Stanton and his ownership group, First Avenue Entertainment LLLP.

Stanton reportedly owns up to 90% of the Mariners and serves as the CEO and chairman of the franchise. He is a well-known businessman in Seattle, with a background in telecommunications, and has led the team's operations since acquiring majority ownership.
