FINAL DATA: MLS 2026 Transfer Tracker
*Image generated with artificial intelligence
Like Europe, the MLS summer transfer window is a perfect opportunity for football clubs in most leagues across Major League Soccer (MLS) to re-tool or completely re-build their squads. In MLS, however, this window is referred to as the “Secondary Transfer Window,” which runs from July 13–September 2, 2026 — right in the middle of the 2026 MLS season. (The Primary Transfer Window serves as the offseason transfer window.)
As of next year, however, the secondary transfer window will take place during the offseason due to the league changing its schedule to a European-style calendar ranging from August to May of the following year. (See our opinion piece on the pros and cons of this calendar change.)
Inspired by our Summer 2026 Transfer Tracker, for the first time ever , we are tracking all transfers completed during the Secondary Transfer Window by the 30 MLS clubs:
This tracker identifies the number of transfers among the these MLS and the total amount of US dollars spent and earned by these clubs within these leagues. That said, the tracker includes overlap in money spent due to intra-league transfers: players moving between clubs within a league.
The data presented below account for transfers completed and registered in Transfermarkt’s database.
Collective Transfer Spending and Revenue
As of September 27, 2026, the 30 MLS clubs have collectively spent €163.5 million on players during the 2026 Secondary Transfer Window. They have also generated €141.8 million in revenue during that period.
Top Spenders
Since the start of the window, Sporting Kansas City have been the highest spenders, speaking €23.6 million, largely due to signing forward André Luiz for €15.5 million from Greek Super League club Olympiacos FC. Colorado Rapids and Atlanta United rank second and third in this category, spending €20.4 million and €19.6 million in revenue, respectively. Colorado’s spending mainly originates from signing forward Morgan Whittaker for €11.2 million from EFL Championship club Middlesbrough FC; Atalanta’s spending largely derives from signing Swiss international and forward Breel Embolo for €17.0 million from Ligue 1 club Stade Rennais.
Figure 1 shows the amount of money spent and by the 10 most active clubs in this window. Transfers indicated in this figure also exclude permanent transfers containing an undisclosed fee, free transfers, loan transfers and loan terminations. It is worth noting, however, that these amounts solely include transfers with a disclosed fee; transfers containing undisclosed fees are not included. They also exclude loan deals that include purchase options.
Top Sellers
During the same period, Colorado Rapids generated the highest revenue among the 30 clubs, earning €26.4 million, solely due to the sales of Australian defender Lucas Harrington to newly promoted Premier League club Hull City and Brazilian forward Rafael Navarro to fellow MLS club St. Louis City SC for €14.8 million and €10.4 million, respectively. Real Salt Lake and LA Galaxy rank second and third in this category, earning €14.3 million and €14.1 million in revenue, respectively.
Figure 2 presents the amount of money spent and earned in transfer income by the 11 most active clubs in this window, with Charlotte FC and Sorting Kansas City ties for 10th. Transfers indicated in this figure also exclude permanent transfers containing an undisclosed fee, free transfers, loan transfers and loan terminations.

Although European transfers generally involve lucrative fees, most of MLS clubs’ major signings are free transfers, with the involved players coming to MLS after their contracts at European or other clubs expire.
