From the WNBA to the SHL: Which Leagues Are Set to Take Off?

For years, the world’s greatest sporting superstars have lit up the biggest stadiums and leagues on the planet, be it in the NFL and NBA or the English Premier League. However, by the season's end, the competitive razzmatazz often fades when the same big-name teams fight it out for yet another title. 

This might explain why fans - and investors - are increasingly turning to alternative sporting leagues. You know the ones, those that have traditionally flown under the radar, but who are experiencing unprecedented growth metrics with the potential to now become billion-dollar enterprises themselves. 

As a result, Bodog ranks the top five most underrated global sports leagues on the up, and the reasons behind their newfound success.

The Building Blocks of a Sports League's Success

As any sports historian will tell you, a strong concept and a multi-million-dollar launch alone doesn't guarantee a successful sports league venture - you only need to look at NFL Europe and the North American Soccer League to see that.

With so many factors needed not just to survive, but to thrive, for a sports league to become a viable proposition, it needs to tick off a whole bunch of prerequisites, including: 

• Massive dedicated fanbases and league communities
• Vibrant gameday atmospheres
• Large TV and streaming audiences
• Viral-like digital and social media growth
• Lucrative sponsorships and broadcasting deals

Tick most of these boxes, and the secret to accelerating the momentum of a modern-day sports league then involves investing in grassroots talent and attracting world-class athletes, whilst elevating the league's marketable commercial viability across every available channel. All these ingredients need to come together at the right time, but when they do, a league now has all the ingredients for explosive expansion on a global scale.

Top Five Underrated Leagues and Tours from Around the World

Granted, every league will offer something totally unique to its devoted fan bases, whether it's a competition model fighting against the glitz and glamour of a more established rival league, or an emerging new sport vying for international recognition. Sure, an elite superstar player can elevate a sports league's visibility single-handedly, but more often than not, it's the caliber of competition across the entire league that genuinely sparks fans' interest. 

No. 1 - Nippon Professional Baseball (NPB) - Japan

First up is one of Asia's wealthiest sports leagues, the Nippon Professional Baseball, which draws upon Japan's national obsession with baseball so intensely that Tokyo itself has five NPB teams. Having recently produced MLB phenoms such as four-time MVP Shohei Ohtani and All-Star Munetaka Murakami, the overall standard of the NPB has also made it a scouting goldmine for MLB franchises. 

Given the NPB average game attendance commands over 31,500 fans, as well as a burgeoning international audience of streamers and overseas broadcasting, it’s no wonder why the league’s popularity is continuing to flourish. 

No. 2 - Football League Championship - England

Calling England's Championship the "second division" simply doesn't do it justice, as not only is it arguably the strongest second-tier soccer competition on Earth, but its crowds, club histories and playing budgets rival those of many top-flight competitions elsewhere in Europe. Due to its highly competitive nature, the Championship is also hugely popular among sports bettors, recently, with scoring on the rise and 25% of games hitting the sportsbook's Over 3.5 goals betting threshold in 2024-2025.

However, the English Championship is perhaps most famous for hosting the "richest game in soccer", as the winner of the playoff final stands to gain an eye-watering £220 million from Premier League revenue and possible future parachute payments. That number gets even bigger if the team survives in the EPL for at least one season.

No. 3 - Women's National Basketball Association - USA

For years, the WNBA has been touted as the next breakthrough league, but it never quite popped the way many thought it might… until now, that is.

For sure, there have been generational talents to grace the WNBA, but no one has done it quite as sensationally as Caitlin Clark. The reason being, Clark - not just a prodigious talent on the court, but an overwhelming fan and media icon too - appears to be the missing ingredient the WNBA has been searching for all these years. 

Granted, the unwanted attention she's garnered from her overzealous opponents has been a catalyst to the league's rise to prominence, but as that died down, Clark's skills on the court have continued to wow fans around the world. So much so, broadcasting heavyweights including ESPN, NBC, Amazon Prime Video and CBS are all battling it out for the right to show more WNBA games - a sign that the WNBA has truly made it.

At any rate, it might be tough to call the WNBA a secret these days, but there’s a good chance it’s still considerably undervalued.

No. 4 - Swedish Hockey League (SHL) - Sweden

Naturally enough, when it comes to ice hockey, the NHL still dominates the sporting headlines, but ask any European fan, and they'll tell you, you might want to check out the SHL - Sweden's own professional hockey league. Consistently ranked as Europe's strongest domestic ice hockey league (particularly with the decline of the Russian KHL), devotees categorically insist that the SHL's fast-paced nature and demanding skill set requirements have resulted in it becoming an enviable talent pipeline for NHL teams.

Having already started to court the eyes of more North American spectators, the SHL's prevalence these days within global ice hockey circles is why many analysts and sportscasters are predicting a rosy future for the SHL.

No. 5 - Premier Padel - International

While the majority of our shortlist so far has featured long-standing sports leagues gaining record surges in traction, our next underrated sports competition - Premier Padel - has become a meteoric success almost overnight. As one of the fastest-growing participation sports, padel has taken off across the world. Premier Padel has turned into the sport's top international circuit for its emerging professional players.

Equivalent to tennis’ more established ATP Tour, Premier Padel is already hosting 25+ tournaments across over 17 different countries in 2026, demonstrating how the concept has propelled recreational participation into a genuine sports league powerhouse endeavor.

How New Leagues Can Dominate and Future Growth

In fairness, the continued growth in popularity of these secondary sports leagues is more a testament to how they've adapted to the need for richer fan experiences and how sports content is consumed these days. After all, modern fandom demands and expects punchier highlights, intimate access to the star players' socials, and online forums to constantly engage with other fans outside of gamedays. 

Sports leagues that wholeheartedly embrace and promote these evolving trends are increasingly amplifying their popularity, which once upon a time in the bygone era of traditional broadcasting would have excluded them from ever gaining notoriety. For the franchises involved too, the growing international scope of a league's development can help unlock lucrative domestic and global merchandise, sponsorship, and broadcasting revenues.

The Bottom Line

Whether it’s the NFL, NBA, or the Champions League, if you’ve grown tired of the same teams being crowned champion year after year, perhaps it’s time to broaden your horizons. With punchier highlights, more competitive action right across the league, and wider-spread coverage than ever before, while the likes of the NPB, WNBA, and the English Championship hit new levels of popularity, don’t be surprised if a brand new competitive format also enters the fold in the next few years.
