Sports betting is often treated as a modern problem. Smartphone apps, live odds and instant payments have made it easier than ever to bet on games. The next FIFA Men’s World Cup is expected to become one of the biggest sports betting events in history. For many people, that raises a familiar concern: is gambling damaging the integrity of sport?
But there is another way to look at the story. Betting did not simply appear after professional sports became popular. In many countries, gambling has been part of spectator sports for centuries. Horse racing in Britain and France attracted betting crowds as early as the 17th century. In the United States, sports gambling was largely illegal outside Nevada until a 2018 Supreme Court decision allowed individual states to legalize it. Yet informal betting had long been present in American sports culture.
Sports historian David Bockino argues that gambling was not just attached to sports from the outside. In some cases, it helped turn ordinary games into commercial spectacles. Early baseball, for example, was once closer to a recreational activity than a national business. People did not automatically assume they would pay money to watch others play. Betting gave spectators a reason to care about the result. A small wager could make one team feel like “your” team, even if you had no personal connection to the players.
This may help explain why gambling, statistics and publicity developed together. Betting created interest in results. Statistics helped people compare players, teams and probabilities. Publicity turned local games into events that wider audiences could follow. In this view, gambling was not merely a side activity. It helped create the habits of attention that modern sports businesses depend on.
That does not mean the relationship has always been comfortable. Leagues and team owners have often worried that gambling could lead to fixed games, damaged trust and lower fan interest. The word “integrity” is often used in this context. It suggests that fans must believe the competition is fair. If people suspect that players, referees or teams are influenced by bets, the value of the sport itself can collapse.
The current boom makes this tension sharper. Legal sports betting can bring advertising money, data partnerships and new ways to keep fans watching. At the same time, it can expose young fans to betting culture and make every moment of a game feel like a financial opportunity. In-game betting, where people bet on events inside a match, such as the next pitch or the next goal, changes the viewing experience even further.
The uncomfortable truth is that sports and gambling have never been completely separate. Gambling helped some sports attract attention, build audiences and become profitable. But the same force that helped sports grow can also threaten what makes them worth watching: uncertainty, fairness and trust.
