Xfinity Mobile Arena

Xfinity Mobile Arena is a multi-purpose indoor arena located in Philadelphia. It serves as the home of the Philadelphia Flyers of the National Hockey League (NHL), the Philadelphia 76ers of the National Basketball Association (NBA), and the Philadelphia Wings of the National Lacrosse League (NLL). The arena lies at the southwest corner of the South Philadelphia Sports Complex, which includes Lincoln Financial Field, Citizens Bank Park, and Stateside Live!.

The arena, initially called Spectrum II during planning, was completed in 1996 to replace the Spectrum as the home arena of the 76ers and Flyers, on the former site of John F. Kennedy Stadium at a cost of $210 million, largely privately financed (though the city and state helped to pay for the local infrastructure). It is owned by Comcast Spectacor, which also owns the Flyers. Since opening, it has been known by a number of different names through naming rights deals and bank mergers, including CoreStates Center from 1996 to 1998, First Union Center from 1998 to 2003, Wachovia Center from 2003 to 2010, and Wells Fargo Center from 2010 to 2025. Naming rights were originally held by CoreStates Financial Corporation, which was acquired by First Union, which later also purchased Wachovia National Bank to rename itself Wachovia Corporation; the combined company was acquired by Wells Fargo in 2008.

In addition to hosting home games for its main tenants, the arena has been the site of a number of other notable athletic events, including games of the 1997 and 2010 Stanley Cup Finals, three games of the 2001 NBA Finals, and various collegiate events for the National Collegiate Athletic Association (NCAA). The arena has hosted two political conventions, hosting the 2000 Republican National Convention and 2016 Democratic National Convention. The arena is a regular venue for concerts and WWE events. The arena has a concert seating capacity of 21,000 seated and at least 21,500 standing.

On January 12, 2025, Comcast Spectacor, Harris Blitzer Sports & Entertainment and the City of Philadelphia announced a deal to replace the arena with a new $1.3 billion privately financed arena to open by 2030. Comcast Spectacor and Harris Blitzer Sports & Entertainment will jointly own the new arena. Demolition will follow once the new project is complete.

Prior to its construction, the proposed arena was tentatively called "Spectrum II". The arena was originally named for locally based CoreStates Financial Corporation, which agreed to pay $40 million over 21 years for the naming rights, with additional terms to be settled later for an additional eight-year period at the end of the contract.

The contract then went through multiple hands due to various bank mergers; first by First Union in 1998, Wachovia in 2003, and finally by Wells Fargo since July 2010. Installation of the new Wells Fargo Center branding began on July 27, 2010, with the removal of the Wachovia Center signage, followed by the installation of the new Wells Fargo Center signage. Work was completed in September 2010.

During the 2015–16 NBA season for a short time, the 76ers ceased recognizing Wells Fargo's naming rights and referred to the facility exclusively as "The Center", as the institution was not a sponsor of the team. The Wells Fargo Center logo decal which sat on the 76ers court was in the most minimal text discernible by television cameras, colored in white to blend in with the floor. (Reportedly, 76ers CEO Scott O'Neil's first idea was to color it with clear-coat paint only visible with UV blacklighting showing the logo during the opening of Sixers games when the arena lights were drawn down; however, the team, after discussion with their lawyers, elected not to do so.) With the start of the new year in January 2016 with input from Comcast Spectacor, the logo decal was enlarged and repainted in black. The 76ers then signed a non-signage sponsorship agreement with Firstrust Bank as their official banking sponsor.

On July 24, 2024, Wells Fargo announced that it would not renew its naming rights deal once it expired in August 2025. On May 6, 2025, Comcast Spectacor and Harris Blitzer Sports & Entertainment announced the arena's new name would be Xfinity Mobile Arena, and lasting through the 2030–2031 season. Xfinity Mobile is a service of Xfinity, a subsidiary of Comcast. The name change was made official on August 14, 2025.
