But which sides truly have the biggest MLS fanbases, and which can be considered the most popular MLS clubs today?
This ranking looks at the MLS teams with the most fans using three factors: average home attendance from the 2024 season, updated attendance figures through August 2025, and social media reach on Instagram and X.

Atlanta United are the undisputed leaders when it comes to MLS attendance. The Five Stripes averaged 46,831 fans per game in 2024 and are still drawing an extraordinary 44,227 in 2025. Mercedes-Benz Stadium has become one of the loudest venues in American sports, where Terminus Legion and Footie Mob lead massive choreographies and chants.
Beyond just numbers, Atlanta revolutionized how soccer is consumed in the United States. Their inaugural season shattered attendance records, and since then, the club has consistently been compared to top European sides in terms of atmosphere.
The fanbase’s influence even extends beyond the stadium, with local businesses, murals, and a growing youth soccer culture feeding into the club’s identity. Their presence extends online with more than 1.7 million combined followers on Instagram and X, showing why Atlanta United belong at the very top of any list of the biggest MLS fanbases.
