https://www.forbes.com/sites/mikeozanian/2021/05/07/worlds-most-valuable-sports-teams-2021/?sh=1f3a46333e9eWFT is #19.
Top teams are Dallas Cowboys, NYY, Knicks, Barcelona, and Real Madrid.
Top premier league teams are #11 Man U and #12 Liverpool, with City tied for 13th (with LA Rams). Chelski (#25) and Arsenal (#38) also make the list.
26 of the top 50 are NFL teams.
US based teams dominate because they share many revenue streams, especially national TV. Owning your stadium helps with the revenue streams, although there is no estimate of the value of the real estate built into these valuations. Had the super league formed with its revenue sharing, Barca would have topped the Cowboys.
Warriors edge out Lakers for #6. Patriots and Giants are the second and 3rd most valuable NFL franchises at #8 & #9. Bayern Munich rounds out the top 10.
In addition to NYY, baseball teams on the list include Doyers #16, BoSox #20, Cubs #22, Giants #28, Mets #47,
