[7][8] After several sellouts for the Seattle Sounders in their inaugural North American Soccer League season, a set of temporary bleachers were installed in the stadium to increase capacity to 17,925 in 1975.

[10] The Sounders moved to the Kingdome at the end of the 1975 season after attempts to negotiate for a long-term lease and management of the stadium with the Seattle School District were unsuccessful.

[12][13] Plans to replace the turf surface and widen the field area were also announced prior to a visit by Major League Soccer officials in 1994 to determine its suitability to host a Seattle team.

[17] The private bidder would pay for the remaining construction costs and operate the venue, which would be used for school sports as well as concerts and cultural events beginning in 2027.

The One Roof Partnership, a partnership between the Seattle Kraken and Oak View Group (the operator of the redeveloped Climate Pledge Arena), proposed a stadium with four stands and seats for 10,000 spectators; its design was inspired by a stadium in Kansas City, Missouri, that was being constructed for the Kansas City Current of the National Women's Soccer League.

[26] The stadium also hosts the annual football championships for the Metro League, which are traditionally played on Thanksgiving Day.

[27][28] As well as hosting two iterations of the Sounders franchise, Memorial Stadium has served as home to several other pro and semi-pro sports teams.

The Seattle Majestics, a women's American football team, played home games at Memorial Stadium from 2007 to 2009 before moving to French Field in nearby Kent.

[29] Seattle Reign FC of the National Women's Soccer League moved to the stadium in 2014 and played with a capacity limited to 6,000 for several seasons.

[7][34] In late May 1995, The Grateful Dead performed their final three Seattle shows as the most significant events to ever take place at this stadium.
