Online Sports Betting: History, Evolution and Trends for the Future

The world of sports betting underwent a radical transformation over the past few decades, particularly with the rise of online platforms. The history of sports betting dates back to ancient civilizations, but it is only in recent years that the internet changed how bets are placed and how the industry operates. Today, online sports betting is a multi-billion-dollar industry that spans the globe, bringing together technology, regulation and a passion for sports in new and exciting ways. In this article, therefore, inplaySoft will explain the history and evolution of this popular form of entertainment and explore some of the main trends for the future!

History of Sports Betting

The origins of sports betting trace back to the ancient Greeks and Romans, who placed wagers on athletic competitions and chariot races. Ancient Greeks famously used the Olympic Games to gamble, and the practice of betting on sporting events was well-documented in Roman society as well. These early forms of betting involved personal stakes and informal wagers among individuals.

In the modern era, sports betting began to formalize with the rise of horse racing in the 19th century. The United Kingdom introduced the first legal betting systems with the establishment of racetracks and regulated betting shops. By the 20th century, the expansion of sports like football (soccer), baseball and basketball allowed for the proliferation of betting markets, which were regulated and controlled by various government entities across different countries.

The United States also has a long tradition of sports betting, particularly on horse racing. However, until the 1990s, betting on most sports outside of horse racing was either illegal or heavily restricted. The major turning point for sports betting in the U.S. came with the passage of the Professional and Amateur Sports Protection Act (PASPA) in 1992, which effectively banned sports betting outside of Nevada.

Online Sports Betting

The birth of online sports betting occurred in the mid-to-late 1990s, when the internet began to gain popularity. In 1996, the first online sportsbook was launched, offering bettors the opportunity to place wagers on various sports from the comfort of their own homes. This innovation changed the game, as it eliminated the need for bettors to physically visit a sportsbook or casino. Instead, bettors could access online platforms through their computers, which quickly proved to be a major convenience.

By the late 1990s and early 2000s, the online sports betting market exploded, driven by increasing internet access, technological advancements and the global rise of the internet as a platform for commerce. Betting websites began to dominate the scene, offering bettors a wide range of sports to wager on, from traditional events like football and basketball to more niche options like darts, snooker, and eSports.

Regulation and Legislation

As the online sports betting industry grew, so did the need for regulation. Governments across the world began to recognize the economic benefits of legalizing and regulating online sports betting, especially in terms of tax revenue. However, the regulatory landscape is complex and varies by country.

In the United States, the fight over sports betting reached a boiling point when PASPA was overturned by the Supreme Court in May 2018. This landmark decision allowed individual states to legalize and regulate sports betting within their borders. The decision opened the door for an explosion of legal sports betting across the country. States like New Jersey, Pennsylvania and Colorado were quick to embrace the opportunity, and as of 2025, over 30 states legalized some form of sports betting, generating billions of dollars in revenue.

Meanwhile, in the United Kingdom, the government regulates online sports betting since the Gambling Act of 2005, which provided a clear framework for online operators. The UK’s model served as a template for many other countries that seek to regulate online gambling. The European Union also enacted laws to harmonize online gambling regulations, allowing for cross-border betting between member states.

Evolution of Online Sports Betting

Online sports betting evolved significantly since its inception. A few key developments that shaped the industry in recent years are:

• Mobile Betting: one of the most significant evolutions in online sports betting was the rise of mobile betting apps. As smartphones became more ubiquitous, online sportsbooks developed mobile-friendly platforms, which allowed users to place bets on-the-go. This development made sports betting more convenient and contributed to a rise in mobile-first bettors.
  
• Live Betting and In-Play Markets: another major shift in online sports betting was the introduction of live betting, also known as in-play betting. This allows bettors to place wagers during an ongoing game, with odds constantly updated in real-time. In-play betting became incredibly popular, as it provides a more dynamic and interactive betting experience. Bettors, for instance, can wager on various events during a football match, such as the next team to score or the outcome of a particular possession.
  
• Betting Exchanges: unlike traditional sportsbooks that set odds and accept bets, betting exchanges allow bettors to act as both the bookmaker and the bettor. These exchanges create a marketplace where users can bet against each other, with the platform acting as an intermediary to facilitate the bets. Betting exchanges became increasingly popular for their transparency and better odds, as bettors are able to set their own terms.
  
• Cash-Out Features: many sportsbooks offer “cash-out” features, which allow bettors to settle a bet before the event is over. This feature allows users to lock in profits or minimize losses based on the state of the event. If a bettor places a wager on a team to win a game and the team is performing better than expected, for example, they can cash out early for a guaranteed profit, even before the game ends.
  
• Data and Analytics: sports betting always relied on statistical analysis, but the advent of big data and artificial intelligence revolutionized how bettors analyze trends, player performance and match outcomes. Today, sophisticated algorithms and machine learning models can predict the likelihood of certain outcomes with incredible accuracy, giving bettors an edge in their wagers.
  

Trends for the Future of Online Sports Betting

Some of the key trends that are likely to shape the trajectory of online sports betting are:

• Integration of Virtual and Augmented Reality: virtual and augmented reality technologies hold the potential to take online sports betting to the next level. Imagine watching a live sports event in a fully immersive 3D environment while placing bets on various aspects of the game. This could change the way users experience sports and gambling, making the entire process more interactive and engaging.
  
• eSports Betting: the rise of competitive video gaming, or eSports, created a new frontier for online sports betting. With tournaments drawing millions of viewers and players, eSports betting is growing rapidly. This market will likely continue to expand, with major bookmakers offering odds on various games and tournaments.
  
• Crypto and Blockchain Technology: cryptocurrencies already begun to make inroads into online betting platforms. Blockchain technology offers benefits like transparency, security and faster transactions, making it a natural fit for the world of online sports betting. As digital currencies become more mainstream, we can expect more betting sites to adopt these payment methods.
  
• Global Expansion and Regulation: as more countries legalize and regulate online sports betting, the market will continue to expand globally. While regulation will help curb illegal betting, it will also require operators to adapt to local laws and consumer preferences. The challenge for sportsbooks will be balancing innovation with compliance, ensuring that bettors are protected and that the industry remains sustainable.

Final thoughts

The evolution of online sports betting has been nothing short of transformative, moving from humble beginnings to a thriving global industry. With advancements in mobile technology, live betting, data analytics and emerging trends, like eSports and blockchain, the future of online sports betting looks exciting. However, as the industry continues to grow, regulation and consumer protection will remain paramount. The future will undoubtedly bring new opportunities and challenges, but one thing is clear: the world of online sports betting is here to stay, and it will continue to evolve in innovative and unexpected ways.
