Julia Koch and her family are known for their significant investments in New York sports. The family had previously invested in other New York sports assets, including BSE Global, the parent company of Brooklyn Nets and New York Liberty.
The Koch family is making a strategic expansion into football through this new agreement. But this agreement does not give the Koch family any way to control the Giants.
John Mara will remain team president and CEO, and Steve Tisch will continue as executive vice president and chairman of the board. Both founding families will still have a strong influence over how the team is run.
Record Valuations Signal NFL’s Dominance in Sports Investment Market
The Giants’ new valuation of $10.3 billion surpasses the previous record set by a 2.35% stake in the Chicago Bears at $8.9 billion. Other NFL teams have also sold minority stakes at high prices.
The New England Patriots sold an 8% stake to Sixth Street Partners and Dean Metropoulos at a $9 billion valuation, while the San Francisco 49ers sold a 3.2% stake at an $8.6 billion valuation.
Private equity firms are now driving a strong interest in NFL ownership and helping to set a floor on team values. These deals address liquidity concerns that once kept investors from entering the market. The NFL remains the most profitable sports league in the world.
The Mara family welcomed the Koch family to the organization. Aside from the new percentage splits, the Giants’ ownership structure stays the same. Moelis & Company and Sullivan & Cromwell handled the transaction for the team.
The franchise enters a new chapter with additional financial firepower from one of America’s wealthiest families. Whether that translates toon-field success remains the ultimate test for any ownership group.
