The ownership groups of the Philadelphia 76ers and Flyers announced plans to build a new arena in South Philadelphia that would open in 2031.

The team, whose ownership group is led by investor Josh Harris, said it had formed a 50-50 joint venture with Comcast to replace its arena in the South Philadelphia stadium district by 2031. Comcast will also take a minority stake in the team and work together on the WNBA bid, the parties said in a joint statement Monday.
