The MLB Postseason was among the most-watched in recent years, but a shorter and lesser-watched World Series knocked viewership further off of last year’s pace.
The 2026 MLB Postseason averaged 5.49 million viewers across Fox Sports, TNT Sports and NBCUniversal, down 13% from last year (6.33M), but otherwise the officially most-watched postseason since 2019. Viewership had been down single-digits entering the World Series, but with this year’s Fall Classic featuring fewer games and fewer viewers than a year ago, the average fell further off of last year’s pace.
Last year’s playoffs culminated with a Game 7 of the World Series that officially ranks as the most-watched Major League Baseball game since 2017, the last of a record seven winner-take-all games. This year’s playoffs ended with a “Gentleman’s sweep” and included only two winner-take-all games.
The postseason was dominated by the eventual champion Brewers, hailing from the smallest TV market in MLB — #39-ranked Nielsen DMA Milwaukee. Yet viewership officially increased 10% from the 2024 postseason (4.96M), which included back-to-back series pitting the nation’s top two markets, Dodgers-Mets in the NLCS and Dodgers-Yankees in the World Series. (The 2024 postseason took place before Nielsen shifted to its current “Big Data + Panel” metric or expanded its out-of-home viewing sample to cover 100 percent of markets in the lower 48 states, and would have averaged more viewers under current methodology.)
Teams from the L.A. and New York markets combined to play a total of 13 games this postseason (seven for the Dodgers, six for the Yankees and zero for the Mets) down from last year (24) and 2024 (32), and the fewest in a postseason since 2023 (three).
A final viewership average for the Brewers-Rays World Series had not been publicized as of Saturday morning, but FOX said Thursday that the Fall Classic averaged 12 million viewers, based on a projected audience of 14.2 million for Wednesday’s clinching Game 5. That is down from the prior two years that featured the Dodgers, but up sharply from the previous non-Dodgers World Series, Rangers-Diamondbacks in 2023 (9.11M).
Depending on where the final average lands, Brewers-Rays could finish as the third-most watched World Series since 2019 and the most-watched that did not involve the Dodgers. (It is not clear whether viewership outpaced Braves-Astros in 2021 or Astros-Phillies in 2022, both of which also round up to an average of 12 million.) That would be a far healthier result than most would have anticipated prior to the start of the series.
At the same time, Brewers-Rays could also finish as the third-least watched World Series on record, a result in keeping with the low expectations. It will for certain rank among the bottom five, joining Rangers-Diamondbacks, the COVID-era Dodgers-Rays in 2020 (9.82M), Braves-Astros in 2021 (11.94M) and Astros-Phillies in 2022 (11.78M). The five non-Dodgers World Series this decade are the five least-watched on record.
While the World Series was among the least-watched on record, the Brewers also played in the most-watched League Championship Series in a decade — as their four-game sweep of the Dodgers averaged 7.53 million, officially the highest for an LCS since Mets-Cubs (another four-game sweep) in 2015.
The Brewers ended up playing in the six most-watched games of the postseason across the five World Series games and Game 1 of the NLCS, which averaged 10.72 million in a post-NFL window — officially the highest for any LCS game since 2010. Milwaukee played in eight of the top ten overall, with Games 2 and 3 of the NLCS also making the list.
The two exceptions were the two games of the Yankees-Red Sox Wild Card series, which averaged 7.41 and 7.31 million viewers in primetime on NBC.
Note that this year’s postseason average excludes two full series — White Sox-Astros and Cubs-Padres in the Wild Card round — that aired on Peacock and NBCSN, figures for which are generally not publicized.
