How Much Could Online Sports Betting Grow as an Industry in 2025?

Sports betting is one of the biggest industries in 2025, experiencing immense growth since the United States Supreme Court struck down the Professional and Amateur Sports Protection Act in 2018. Missouri is set to launch online sports betting by December 1st, 2025, making it the 31st state in the United States to legalize mobile sports betting.

Several metrics imply online sports betting will continue to undergo significant growth for the remainder of 2025. This applies to countries worldwide, as well as within the United States. 

The projected revenue in the online sports betting market is $17.2 billion in 2025 with an annual growth rate of 7.5 percent. By 2030, the projected market volume is $24.7 billion USD, including over 57 million sports bettors. 

Online sports betting allows registered customers to place wagers directly from their phone or desktop. This convenience is a huge factor in the growth of this industry in 2025, with retail sportsbooks no longer being the primary location to bet on sports. 

Live streaming and in-play betting are available on virtually every licensed online sportsbook operator. These features help engage sports bettors and keep them active within the mobile app. 

There are no shortage of sports betting markets and bet types to wager on. The growth of eSports has led to its own betting market, with online sportsbook customers being afforded opportunities to bet on a variety of individuals and teams playing video games. 

Smartphones have been particularly instrumental in driving growth within the online sports betting industry. Over half of the world’s population owns a smartphone, totaling 4.3 billion people. 

Therefore, when incentives such as quick deposit and withdrawal methods are offered through online sportsbooks, plus bonus bet credits, it’s all easily accessible and completed by a consumer. The sign-up process is expedited and relies on geo-location tracking to verify an individual is at least 18 or 21 years old, while physically located in a legal sports betting state.

Offshore sports betting sites, which are not regulated by an agency or committee appointed by a specific state, unlike legal online sportsbooks in the United States, take advantage of their lack of oversight, preying upon sports bettors. Without facing repercussions, placing sports bets on offshore sportsbooks carries a greater risk. 

The onset of legal online sports betting has seen its rise in popularity, fueled by continuously improved technology. Whether it’s a simple push notification, live streaming, in-game betting odds, or virtual table games in iGaming casinos, this immersive experience has led to a surge in online sports betting. 

Partnerships and advertisements also go a long way to promote online sports betting. Fanatics Sportsbook offers its customers FanCash with each wager placed, in addition to select promotional offers.

FanCash can be converted into bonus bet credits or kept to purchase official sports merchandise gear from the Fanatics.com website via the Fanatics Sportsbook mobile app. This is a great example of how online sports betting continues to evolve and grow due to its creative strategies with modern technology.
