MLS is seizing World Cup momentum with major changes including transition to a summer-to-spring calendar after this season, roster rule adjustments, and Commissioner Don Garber's planned departure. The league saw a 58% ticket sales increase during and after the tournament, boosted by signings like Robert Lewandowski (Chicago Fire) and Antoine Griezmann (Orlando City).

Forty-five MLS players featured on World Cup rosters, with 43 academy-developed players participating. Lionel Messi led Argentina to the final. Garber highlighted academy successes including Ricardo Pepi, Tyler Adams, and Alphonso Davies, plus recent transfers of Benji Flowers to Chelsea and Cavan Sullivan to Manchester City.

A shortened 14-game season in early 2027 precedes the full 2027-28 campaign starting in July. Garber emphasized alignment with the global calendar but ruled out promotion/relegation. His contract runs through 2027, with a successor potentially named next week.
