The New York Giants are primarily owned by the Mara and Tisch families. They have been the majority owners for many decades, with the Mara family owning the team since its founding in 1925 and the Tisch family acquiring a 50% share in 1991. Currently, John Mara and Steve Tisch, sons of the original owners, serve as president, CEO, and co-owners of the Giants. Recently, in 2025, the Koch family agreed to purchase a 10% minority stake in the New York Giants. This deal, pending approval from NFL owners, values the team at a record $10 billion, making it the highest valuation ever for an NFL franchise. After this sale, the Mara and Tisch families will each hold 45% ownership, while the Koch family will hold 10%, but the Koch family will not have controlling interest. In summary, the owners of the New York Giants in 2025 are:
- Mara family (45%)
- Tisch family (45%)
- Koch family (10%, minority stake)
John Mara and Steve Tisch remain the majority owners and top executives of the team.
