When you think about the blue-blood franchises of the NFL, the New York Giants are basically the gold standard. They’re the "Old Guard." While other teams change owners like people change Spotify playlists, the Giants have been a family affair since the Coolidge administration. But honestly, if you think it’s just one guy calling all the shots from a mahogany desk, you've got it wrong.
The ownership of this team is a fascinating, sometimes messy, and incredibly stable 50/50 split. Or it was, until very recently.
The Dual Monarchy: Mara and Tisch
Right now, the New York Football Giants are owned by two primary families: the Maras and the Tisches.
John Mara serves as the President and CEO. He’s the face of the franchise. If there’s a league meeting or a press conference about a coaching change, he’s the one at the microphone. Steve Tisch is the Chairman and Executive Vice President. While Steve spent a huge chunk of his career in Hollywood winning Oscars for movies like Forrest Gump, he’s deeply involved in the team’s big-picture strategy.
A Partnership Born of a Feud
It wasn’t always this way. For decades, the Maras owned the whole thing. But families being families, things eventually blew up. Back in the late 80s, the team was split between Wellington Mara and his nephew, Tim Mara. They didn't just disagree; they basically stopped speaking. They even had a partition built in the owners' box so they didn't have to look at each other.
In 1991, Tim Mara decided he’d had enough and sold his 50% stake. Enter Bob Tisch.
Bob was the co-founder of Loews Corporation and a former U.S. Postmaster General. He bought into the Giants for about $75 million. Fast forward to 2026, and that investment looks like the greatest bargain in the history of capitalism. When Wellington and Bob both passed away in 2005, their sons, John and Steve, took the reins.
The 2025 Julia Koch Bombshell
For over 30 years, the 50/50 split was the law of the land. Then came October 2025.
In a move that surprised a lot of traditionalists, the NFL owners approved the sale of a 10% minority stake to Julia Koch and her family. If that name sounds familiar, it should. She’s the widow of David Koch and one of the wealthiest women on the planet.
- The Stake: 10% non-controlling interest.
- The Reason: Capital infusion for stadium upgrades and "future opportunities."
- The Impact: Minimal on the field, but massive for the balance sheet.
Despite this sale, the Mara and Tisch families still hold 45% each and maintain total control over the team's operations. Julia Koch isn't going to be picking the starting quarterback or deciding if the team should go for it on 4th-and-short. She’s a silent partner, albeit an incredibly wealthy one.
The $500 Investment
It’s almost impossible to talk about who owns the New York Football Giants without mentioning the original price tag. In 1925, Tim Mara—John’s grandfather—bought the franchise for $500.
Basically, he bought an NFL team for the price of a mid-range smartphone.
Legend has it Tim was a bookmaker who didn't even know much about football. He just thought an "exclusive franchise for anything in New York" had to be worth five hundred bucks. He was right. Today, the Giants are valued at upwards of $7.5 billion.
How the Power is Actually Shared
You might wonder how two different families share a sandbox without throwing toys at each other. They’ve actually developed a pretty specific rhythm over the last three decades.
John Mara handles the "football" side of the business. He’s the one who interacts with General Manager Joe Schoen and oversees the day-to-day operations at the Quest Diagnostics Training Center. Steve Tisch tends to focus more on the commercial and entertainment side—branding, the fan experience, and the league’s media interests.
Recent Leadership Moves
In early 2026, we saw this ownership duo make one of their most aggressive moves in years. They landed John Harbaugh as the new head coach.
This wasn't just a front-office hire. Reports showed that Steve Tisch flew Harbaugh in on his private plane, and both owners sat down for a marathon dinner at Elia Mediterranean Restaurant to seal the deal. It shows that while they've brought in minority investors like the Kochs, the Mara-Tisch duo is still very much "hands-on" when it counts.
Common Misconceptions
People often think the Giants are owned by the same group that owns the Jets because they share MetLife Stadium. Nope.
The Jets are owned by Woody Johnson (of Johnson & Johnson fame). The Giants and Jets are roommates who split the rent on the stadium, but they are completely separate businesses. They don't even share a kitchen.
Another weird one? Some fans think the team is "publicly owned" like the Green Bay Packers. Definitely not. You can't buy shares of the Giants on the New York Stock Exchange. It is a private, family-run operation, and the Maras have been very vocal about wanting to keep it that way for another hundred years.
Why This Matters for Fans
Ownership stability is the secret sauce for the Giants. While other teams go through "rebuilds" that last twenty years because the owner keeps firing the GM, the Giants tend to be patient. Sometimes too patient, according to some fans.
But that patience is why they have four Super Bowl trophies in the lobby.
The entry of the Koch family signifies a new era where "Legacy" teams are finally opening the doors to private equity and outside billionaires to keep up with the skyrocketing costs of modern sports. It’s a way to stay competitive without the Maras or Tisches having to sell the family jewels.
What you should do next:
If you're tracking the future of the franchise, keep a close eye on the MetLife Stadium renovations scheduled for the 2026-2027 offseason. The capital from the Koch family investment is expected to be funneled directly into these upgrades. You can also monitor the official NFL Ownership diversity reports if you're interested in how the league's "Old Guard" is changing its makeup.
