MLS Cup Surges to Record 4.6M Viewers As Nielsen Sorts Data Issues

Even in a crowded sports weekend led in part by college football’s conference championships, Major League Soccer found its own sizable audience.

The league said Tuesday that it posted an aggregate audience of 4.6 million viewers globally across linear and streaming on Dec. 6 for its MLS Cup, won by Inter Miami over the Vancouver Whitecaps—representing the largest-ever audience for the championship match. 

That figure combined coverage from Fox and Apple TV, as well as on a series of other international distribution partners including TSN, RDS, and TNT. On Apple TV specifically, MLS Cup aired for free in more than 100 countries.

The average panel-only TV audience in the U.S. of 994,000 on Fox and Fox Deportes more than doubled last year’s comparable figure of 468,000 for a match between the L.A. Galaxy and New York Red Bulls.

MLS did not specifically break down the total viewership further, but said the majority of the audience came from the U.S. The league, however, said that more than 70% of the Apple TV viewers for MLS Cup were under the age of 45, further showing the younger audiences that streaming can provide sports leagues. Social impressions around the match grew 532% to a record of 798 million.

Nielsen Issues

The MLS Cup viewership numbers arrived after a three-day delay with Nielsen, as the measurement agency continues to sort through issues with its data collection. Even as many sports audiences have reached record levels this fall, particularly in the NFL and college football, the new Big Data + Panel methodology continues to run into occasional problems. 

MLS said that Nielsen was “reviewing a potential issue in its updated Big Data + Panel sample that may have underreported viewership on Fox.” Updated figures are expected once a review of the data collection issue is complete.

This year’s title, won by Inter Miami, completed a storybook season for the club and Argentine star Lionel Messi, who had a league record 15 goal contributions during the postseason. On Tuesday, Messi also claimed a repeat win as the MLS Most Valuable Player, becoming the first player in league history to claim the honor in consecutive years. 

The championship figure also extends a run of audience growth for MLS this year, with playoff audiences through the conference finals rising 23% to an average of 711,000 per match, and a regular season that reached 3.7 million gross live match viewers across linear and streaming, up 29% from 2024. 

“This puts a real exclamation point on the season and sets us up really well going into next year,” MLS EVP of media Seth Bacon tells Front Office Sports.

The MLS Cup audience, meanwhile, also compares favorably to an average viewership of 1.184 million for the National Women’s Soccer League title game on Nov. 22, setting a record for that league.

MLS will go into next season with a reworked rights agreement with Apple that will place its matches within the main Apple TV streaming service.
