MLS Expansion Teams: Complete History & Timeline
Every MLS expansion team from 1998 to today. Full timeline, expansion fees, and how each new club joined Major League Soccer.
Major League Soccer launched in 1996 with 10 teams. As of 2026, the league has grown to 30 clubs, with plans to reach at least 32. That growth has not been steady or smooth -- it has involved contractions, long pauses, bidding wars, and expansion fees that have skyrocketed from $7.5 million to $400 million and beyond.
This is the complete history of every MLS expansion team, organized chronologically with the context behind each addition. For a broader look at where the league is headed next, see our guide to MLS expansion and growth.
The Original 10 (1996)
Before covering expansion teams, it is important to know the founding clubs. MLS kicked off on April 6, 1996, with these 10 charter members:
- Columbus Crew (now Columbus Crew SC)
- D.C. United
- New England Revolution
- NY/NJ MetroStars (now New York Red Bulls)
- Tampa Bay Mutiny (ceased operations 2001)
- Colorado Rapids
- Dallas Burn (now FC Dallas)
- Kansas City Wiz (now Sporting Kansas City)
- LA Galaxy
- San Jose Clash (now San Jose Earthquakes)
Of the original 10, two no longer exist (Tampa Bay Mutiny and Miami Fusion, added in 1998), and several have rebranded significantly.
First Wave of Expansion (1998-2005)
Miami Fusion (1998) and Chicago Fire (1998)
MLS expanded to 12 teams in 1998, adding the Miami Fusion and Chicago Fire. The expansion fee for each was approximately $7.5 million.
The Chicago Fire had an extraordinary debut, winning both MLS Cup and the U.S. Open Cup in their inaugural 1998 season -- a feat no expansion team has matched since. The Fire became a stable franchise that continues today.
The Miami Fusion had a more turbulent path. Despite solid on-field performance (they won the Supporters' Shield in 2001), poor attendance at Lockhart Stadium in Fort Lauderdale led MLS to fold the team after the 2001 season. Miami would not return to MLS until Inter Miami joined in 2020.
Contraction: 2002
Before expanding further, MLS actually contracted. After the 2001 season, the league eliminated both the Miami Fusion and Tampa Bay Mutiny, dropping from 12 to 10 teams. MLS was losing money -- reportedly $250 million in its first five years -- and smaller markets could not sustain attendance. This contraction period is often forgotten but was a genuine existential crisis for the league.
San Jose Earthquakes Hiatus and Return
The San Jose Earthquakes ceased operations after the 2005 season when the ownership group relocated the team to Houston, where it became the Houston Dynamo in 2006. San Jose was re-established as an expansion team in 2008 with new ownership.
Real Salt Lake (2005)
Real Salt Lake joined MLS in 2005 with an expansion fee of approximately $10 million. Based in Sandy, Utah (near Salt Lake City), RSL initially struggled but became a model franchise after winning MLS Cup in 2009 and building Rio Tinto Stadium (now America First Field), one of the first soccer-specific stadiums built through private investment.
Chivas USA (2005)
Chivas USA joined alongside RSL in 2005, owned by Jorge Vergara, the owner of C.D. Guadalajara (Chivas) in Liga MX. The expansion fee was approximately $10 million. The team shared the Home Depot Center (now Dignity Health Sports Park) with the LA Galaxy.
Chivas USA was a troubled franchise from the start. Sharing a stadium with the Galaxy made them perpetual tenants, and the team faced lawsuits over discriminatory practices under later management. MLS purchased the team back in 2014 and relaunched it as LAFC in 2018.
Houston Dynamo (2006)
The Houston Dynamo was technically not an expansion team but a relocation of the San Jose Earthquakes. However, they received a new identity, new stadium plans, and effectively functioned as a new franchise. Houston won back-to-back MLS Cups in 2006 and 2007.
Second Wave: The Soccer-Specific Stadium Era (2007-2012)
Toronto FC (2007)
Toronto FC became the first Canadian MLS team in 2007. The expansion fee was approximately $10 million. TFC's arrival at BMO Field was a cultural event -- the club sold out its first match in minutes and established one of the most passionate supporter cultures in MLS.
Toronto's early years were defined by losing, but the club's willingness to invest eventually paid off. After signing DP players Sebastian Giovinco, Michael Bradley, and Jozy Altidore, TFC won MLS Cup in 2017 with one of the best regular seasons in league history.
San Jose Earthquakes (2008)
The San Jose Earthquakes returned as an expansion team in 2008 after a two-year absence. The expansion fee was approximately $10 million. San Jose has remained in MLS since, though the club has struggled for consistent on-field success.
Seattle Sounders FC (2009)
The Seattle Sounders FC arrival in 2009 was a watershed moment for MLS expansion. The expansion fee was $30 million -- a significant jump from previous fees.
Seattle immediately shattered attendance records, averaging over 30,000 fans per match in their first season at CenturyLink Field (now Lumen Field). The Sounders' success proved that MLS could draw NFL-level crowds in the right market. Seattle went on to win MLS Cup in 2016 and 2019.
Philadelphia Union (2010)
The Philadelphia Union joined in 2010 with an expansion fee of approximately $10 million. The club built Subaru Park (originally PPL Park) in Chester, Pennsylvania, and has developed one of the league's best academies, producing homegrown talents who have transferred to European clubs.
Portland Timbers (2011)
The Portland Timbers entered MLS in 2011, paying an expansion fee of approximately $35 million. Like Seattle, Portland brought an existing soccer culture and passionate supporter base. Providence Park's intimate atmosphere and the Timbers Army supporters group became iconic. Portland won MLS Cup in 2015.
Vancouver Whitecaps FC (2011)
The Vancouver Whitecaps joined alongside Portland in 2011 as MLS's third Canadian team. The expansion fee was approximately $35 million. The Whitecaps play at BC Place and have been competitive but have not yet won MLS Cup.
Montreal Impact / CF Montreal (2012)
The Montreal Impact (now CF Montréal) became the fourth Canadian MLS team in 2012, with an expansion fee of approximately $40 million. The club plays at Stade Saputo and rebranded to CF Montréal in 2021.
Third Wave: The $100M+ Era (2015-2020)
New York City FC (2015)
New York City FC launched in 2015 as a joint venture between City Football Group (Manchester City's ownership) and the New York Yankees. The expansion fee was $100 million, marking the first time MLS broke nine figures.
NYCFC initially played at Yankee Stadium -- a baseball venue with an awkward narrow pitch -- while pursuing a soccer-specific stadium. The club won MLS Cup in 2021. As of 2026, NYCFC's long-awaited stadium project in Willets Point, Queens, is under construction.
Orlando City SC (2015)
Orlando City also joined in 2015 with an expansion fee of approximately $70 million. The club built Exploria Stadium in downtown Orlando and quickly became an attendance leader in MLS.
Atlanta United FC (2017)
Atlanta United entered MLS in 2017, paying approximately $70 million. The club's impact was immediate and enormous. Playing at Mercedes-Benz Stadium, Atlanta shattered attendance records with an average of over 50,000 fans per match. They won MLS Cup in their second season (2018) under manager Tata Martino, with a roster built around DPs Josef Martinez, Miguel Almiron, and Ezequiel Barco.
Atlanta's success validated the model of investing heavily in young talent, building a strong brand, and leveraging a major-market stadium.
Minnesota United FC (2017)
Minnesota United joined alongside Atlanta in 2017, paying approximately $75 million. The Loons play at Allianz Field in Saint Paul, one of the most acclaimed soccer-specific stadiums in MLS.
LAFC (2018)
Los Angeles FC launched in 2018 with an expansion fee of approximately $110 million. Built on the bones of the defunct Chivas USA franchise, LAFC was a fresh start for a second LA team. Banc of California Stadium (now BMO Stadium) in the Exposition Park neighborhood gave LAFC its own identity, and the 3252 supporters group quickly became one of the loudest in MLS.
LAFC won MLS Cup in 2022 in one of the most dramatic finals in league history, with a penalty shootout victory over Philadelphia.
FC Cincinnati (2019)
FC Cincinnati entered MLS in 2019 after setting USL attendance records. The expansion fee was approximately $150 million. The club built TQL Stadium, a 26,000-seat venue that opened in 2021. After a rocky start in MLS, Cincinnati has become a consistent playoff contender.
Inter Miami CF (2020)
Inter Miami launched in 2020, co-owned by David Beckham -- whose arrival to MLS in 2007 created the DP rule that now bears his nickname. The expansion fee was approximately $25 million (negotiated as part of Beckham's original MLS contract, which included a discounted expansion option). Inter Miami plays at Chase Stadium in Fort Lauderdale while planning a permanent stadium in Miami's Freedom Park.
The 2023 signing of Lionel Messi transformed Inter Miami from a struggling expansion team into a global phenomenon, drawing record attendance and worldwide media attention.
Nashville SC (2020)
Nashville SC joined in 2020 with an expansion fee of approximately $150 million. The club plays at GEODIS Park, a purpose-built 30,000-seat stadium that is the largest soccer-specific stadium in the United States and Canada.
Austin FC (2021)
Austin FC entered MLS in 2021, paying approximately $200 million. Q2 Stadium in Austin has become one of the best atmospheres in MLS, and the club made the playoffs in just its second season.
Charlotte FC (2022)
Charlotte FC joined in 2022 with an expansion fee of approximately $325 million. Playing at Bank of America Stadium (shared with the NFL's Carolina Panthers), Charlotte set an MLS single-game attendance record of 74,479 in their home opener.
St. Louis CITY SC (2023)
St. Louis CITY SC launched in 2023, paying approximately $200 million. CITYPARK stadium, a 22,500-seat venue, was built specifically for the club. St. Louis made the playoffs in their inaugural season, a strong debut.
The Expansion Fee Trajectory
The escalation of MLS expansion fees tells the story of the league's growing value:
| Year | Team | Fee (approx.) | |------|------|---------------| | 1998 | Chicago Fire | $7.5M | | 2005 | Real Salt Lake | $10M | | 2009 | Seattle Sounders | $30M | | 2015 | NYCFC | $100M | | 2017 | Atlanta United | $70M | | 2019 | FC Cincinnati | $150M | | 2021 | Austin FC | $200M | | 2022 | Charlotte FC | $325M | | 2025+ | San Diego FC | $400M+ |
The 50x increase from $7.5 million (1998) to $400 million (2025) reflects MLS's transformation from a league fighting for survival to one valued at over $500 million per franchise on average.
Current and Upcoming Expansion
As of 2026, MLS has 30 teams. San Diego FC joined in 2025 as the most recent expansion club:
- San Diego FC joined in 2025, with a reported expansion fee of $400 million or more. The club plays at Snapdragon Stadium while pursuing a soccer-specific venue.
For the latest on where MLS is heading next -- including potential expansion to Las Vegas, Phoenix, Detroit, and beyond -- see our comprehensive MLS expansion guide. The league has indicated a target of at least 32 teams, with commissioner Don Garber suggesting the ceiling could be even higher.
What Makes an Expansion Team Successful?
Looking across nearly three decades of MLS expansion, several patterns emerge for successful new clubs:
Soccer-specific stadium. Teams that build or have immediate access to a purpose-built stadium consistently outperform those playing in NFL or baseball venues. LAFC, Nashville, St. Louis, and Austin all launched with dedicated venues and strong attendance.
Committed ownership. The expansion fee is just the entry ticket. Successful clubs invest in scouting, academies, DPs, and front-office talent. Atlanta United's willingness to spend $30+ million on transfers in their first two years set them apart.
Existing soccer culture. Markets with existing lower-division soccer support (Seattle, Portland, Cincinnati, Sacramento) tend to transition to MLS more smoothly than cold-start markets.
Patience with roster building. The most successful expansion teams accept a 2-3 year building period. Rushing to compete by overspending on aging DPs has historically backfired.
MLS expansion has been one of the great growth stories in American professional sports, and the league's trajectory suggests more chapters are still to come.
