The Patriots, the Revolution and Gillette Stadium are technically part of the Kraft Group, a holding company that's privately owned by the Kraft family. The company also includes the Rand-Whitney Group (Worcester) and International Forest Products which, taken together, are the largest privately-held paper and cardboard manufacturer in the U.S. Chances are that we've all received something shipped in one of their cardboard cartons (especially if you've purchased a Patriot missile, apparently - who knew?).
Other Kraft Group companies are involved in real estate development and financial services. Estimated total annual revenues are in the $3.5bn-$4.0bn range.
Bob is CEO and Jonathan is President of both the Kraft Group and the Patriots. Bob and Myra had three other sons - Daniel, Joshua and David. AFAIK, Daniel (President of IFP) is the only one besides Jonathan who's directly involved in the family business.
When Bob retires, I'd assume Jonathan would succeed him as CEO. When he passes, the four brothers retain joint ownership of the Kraft Group, including the Patriots.
According to Forbes, in 2017, the Patriots are the second highest valued franchise in the NFL at $3.5bn, behind only the Cowboys at $4.2bn. The Pats are also the 6th highest-valued sports franchise in the world, behind the Yankees and Manchester/Barcelona and Madrid in soccer. The value of the Pats franchise increased another 6% in 2016.
I'd guess that, until/unless something goes seriously awry with the financial situation of the Kraft Group (or with the relationship of the brothers), I can't imagine the Pats being sold, in whole or in part, to outside investors anytime soon.
Just a guess, but it seems like Bob may retire as CEO of the Pats and of the Kraft Group when BB and Brady retire. What may or may not happen to the value of the Pats/Kraft Group afterward ... who knows?
