Fan engagement refers to the level of connection and participation fans have with a sports league beyond watching games. It includes everything from following matches and attending live events to discussing storylines on social media and playing fantasy sports.
For sportsbooks, these highly engaged audiences represent the greatest opportunity to attract bettors and turn them into customers who stay active before, during, and after every game.
In this article, you’ll learn which sports leagues have the best fan engagement so you can prioritize the competitions that drive the most betting activity and long-term player retention.
Fan engagement should extend well beyond matchday. Activities and events like fantasy sports, drafts, transfer windows, rivalries, and playoffs keep audiences invested throughout the season.
Major leagues have both massive international audiences and passionate local supporters, creating consistent interest across multiple markets.
Historic rivalries, star players, competitive title races, packed stadiums, and active digital communities all contribute to sustained fan interest across different sports.
Highly engaged audiences follow matches, player performances, standings, and league storylines closely, and that knowledge and interest naturally translate into betting.
LSports provides low-latency coverage across 100+ sports, 15,000+ leagues, and 2,500 markets, as well as various engagement tools, helping you expand your sportsbook offering and deliver a better customer experience.
The Premier League, NFL, and NBA are among the sports leagues with the strongest fan engagement, based on factors such as audience size, attendance, fantasy sports participation, digital engagement, and year-round fan activity. However, because fan engagement can be measured in different ways, the leagues below are not listed in a particular order.
The Premier League has one of the largest and most engaged global audiences in sport. The league reaches 189 countries and 900 million homes, and draws an estimated global audience of 1.87 billion.
Its global appeal is also reflected in markets where soccer competes with well-established domestic sports. During the 2025/26 season, NBC averaged 1.2 million viewers for Premier League matches on its broadcast network, which is the highest figure since it began airing the competition.
Fantasy Premier League (FPL) further strengthens fan engagement by giving supporters a reason to follow every match, not just those involving their favorite club. The official fantasy game attracted more than 11.4 million verified teams during the 2024/25 season, with millions of managers tracking player performances, making weekly transfers, and competing throughout the campaign.
The National Football League (NFL) also has one of the most engaged fan bases in the world, as millions of fans follow every stage of the season. According to the NFL, the 2025 regular season averaged 18.7 million viewers per game, a 10% increase from 2024. This is the league’s second-highest regular-season average since audience measurement began in 1988.
The league also reported that the 2025 Thanksgiving matchup between the Kansas City Chiefs and Dallas Cowboys attracted 57.2 million average viewers, becoming the most-watched regular-season game in NFL history.
With each team playing just one regular-season game per week, fans spend the days between matchups discussing injuries, analyzing upcoming opponents, following betting odds, setting fantasy football lineups, and debating predictions. Every game carries significant weight in the playoff race, keeping interest high from Week 1 through the postseason.
Beyond the games themselves, the NFL keeps fans engaged year-round through:
The National Basketball Association (NBA) has built one of the world’s most engaged fan communities by combining global star power with a fast-paced schedule that keeps fans connected almost every day.
During the 2025/26 regular season, 170 million people in the United States watched NBA games across ABC and ESPN, Amazon Prime Video, NBC and Peacock, and NBA TV. That was the league’s highest total reach in 24 years and represented an 86% increase from the previous season.
The NBA’s fan engagement is fueled by both its players and its schedule. Games take place almost every night during the regular season, so fans constantly follow results, player performances, injuries, and playoff standings. The NBA also keeps fans engaged throughout the year with:
The Bundesliga has one of the strongest match-going cultures in world soccer, built on low ticket prices and standing terraces that most other top leagues have phased out. During the 2025/26 season, Bundesliga stadiums averaged 42,332 spectators per match, the highest of Europe’s five major domestic soccer leagues.
The league’s popularity extends beyond the stadium, with Sky Sport’s Bundesliga broadcasts reaching an average aggregated audience of 4.7 million viewers per matchday in 2025/26.
The Bundesliga’s fan engagement is driven by historic rivalries, attacking soccer, and a reputation for developing young talent. Clubs such as Bayern Munich, Borussia Dortmund, Eintracht Frankfurt, and FC Köln attract loyal fan bases, while the title race, European qualification, and relegation battle keep supporters invested throughout the season.
Serie A has one of the world’s most recognizable soccer brands, combining historic clubs, passionate rivalries, and a style of play that attracts fans far beyond Italy. The league is broadcast in 200+ territories through 90+ international partners, giving supporters worldwide access to every stage of the season.
Serie A’s fan engagement is driven by iconic clubs such as Juventus, Inter Milan, AC Milan, Napoli, and Roma, along with competitive title races, the battle for European qualification, and relegation drama.
Its growing international appeal is also reflected in the United States, where the cumulative live audience for the first half of the 2024/25 season increased by 50% compared with the same period a year earlier.
LaLiga has built one of soccer’s largest international audiences, broadcasting matches in more than 185 countries. Its biggest single draw is El Clásico between Real Madrid and Barcelona, widely regarded as one of the most-watched club soccer matches in the world. The fixture has an estimated global audience of around 650 million viewers.
The league is also popular in the United States. During the 2025/26 season, it reached 20.1 million viewers across ESPN platforms, a 10% increase from the previous season. The May 2026 El Clásico attracted 1.3 million combined viewers across ESPN, ESPN Deportes, and ESPN+, making it the most-watched LaLiga Clásico ever on ESPN.
Beyond live broadcasts, LaLiga maintains one of soccer’s largest digital communities. In 2024, the league reported more than 230 million followers across 16 social media platforms, with content published in 20 languages.
Major League Baseball (MLB) benefits from a combination of daily routine, statistical depth, historic teams, local loyalty, and a growing international audience. Its 162-game regular season gives fans something to follow nearly every day for six months.
During the first part of the 2025 season, ESPN’s MLB games averaged 1.74 million viewers, a 22% year-over-year increase and the network’s strongest start to a baseball season since 2017.
The 2025 World Series demonstrated MLB’s international potential. According to an MLB press release, Game Seven averaged 51 million viewers across the United States, Canada, and Japan, making it the most-watched MLB game in 34 years. The full seven-game series averaged 34 million viewers across those three countries.
International athletes have made MLB relevant to audiences in Japan, South Korea, Latin America, Canada, and many other markets. At the same time, local broadcast habits and team histories keep clubs closely connected to their home cities.
The National Hockey League (NHL) has one of the most passionate fan bases in North American sports, with games broadcast in more than 260 countries and territories. The league’s global audience continues to grow thanks to international stars, outdoor showcase events, and one of the most intense postseasons in professional sports.
Fan engagement is high both on television and in the arena. During the 2025/26 season, the NHL set a fourth consecutive regular-season attendance record, welcoming 23.16 million fans and filling arenas to 97.5% of capacity.
The 2026 Stanley Cup Playoffs became the most-watched NHL playoffs on record in the United States, with 1.8 million viewers per game. The Final averaged 5.2 million viewers across six games, making it the most-viewed Final since 2019.
