In the 2023 season, the only MLS teams that will not field Next Pro sides are CF Montréal and D.C. United. Following the folding of the Development Academy, MLS announced its own development league in 2020. It includes all of the MLS team academies as well as 95 clubs across the country; many of which were a part of the Development Academy. Stadiums Since 1999, the league has overseen the construction of twelve stadiums specifically designed for soccer. The development of soccer-specific stadiums owned by the teams has generated a better gameday experience for the fans. The soccer-specific stadiums have yielded positive financial results as teams were no longer required to pay to rent out facilities and gained control over revenue streams such as concessions, parking, naming rights, and the ability to host non-MLS events. Several teams have doubled their season tickets following the team's move into a soccer-specific stadium.

The 2007 season brought the opening of Dick's Sporting Goods Park for the Colorado Rapids and BMO Field for Toronto FC. Near the end of the 2008 season, Rio Tinto Stadium (now known as America First Field) became the home of Real Salt Lake, which meant that for the first time in MLS history a majority of MLS's teams (8 out of 14) played in soccer-specific stadiums. Red Bull Arena, the new home of the New York Red Bulls opened for the start of the 2010 season, and the Philadelphia Union opened PPL Park, now Subaru Park, in June 2010, midway through their inaugural season. The following season, in 2011, the Portland Timbers made their MLS debut in a newly renovated Jeld-Wen Field, now renamed Providence Park, which was originally
