who owns the ny giants

The New York Giants are primarily owned by the Mara and Tisch families. John Mara and Steve Tisch, sons of the original owners, serve as the majority owners and maintain control of the team. Recently, in 2025, the Giants agreed to sell a 10% minority ownership stake to the billionaire Koch family, specifically Julia Koch and her family. This deal values the Giants at a historic $10 billion, which is the highest valuation ever for a sports franchise. The Koch family's stake is non-controlling, and the Mara and Tisch families will retain 90% ownership, split evenly at 45% each after the transaction. The sale is pending approval by NFL owners but marks the entry of a new minority owner in the Giants organization for the first time in over three decades.
