The Yankees are worth an estimated $3.3 billion, making them by far the most valuable Major League Baseball franchise, according to Bloomberg News, well ahead of the Dodgers at $2.1 billion.
The Mets ranked fourth at $2.05 billion, just behind the Red Sox's $2.06 billion.
Bloomberg estimated that the average value of franchises is $1 billion. Forbes estimated the average at $744 million in its most recent annual survey of team valuations.
The same Forbes report, issued in March, pegged the Yankees' MLB-high worth at $2.3 billion, with the Mets ranking sixth at $811 million.
Bloomberg said it used data from ticket sales, concessions, sponsorships and broadcast rights, as well as interests in TV channels, radio stations and real estate. The Yankees and Mets own pieces of YES and SNY, respectively, regional networks that carry their games.
The Mets' 65-percent stake in SNY was valued at $1.2 billion by Bloomberg, vastly boosting the franchise's overall value. Profits for YES and SNY long have helped offset losses by the baseball teams whose games they carry.
