# Sports Betting

Sports betting involves the activity of placing bets on the outcome of sporting results. The most popular sports by betting volume are European football / soccer, tennis, American football, horse racing, basketball, golf and boxing/MMA.

Sports betting is the most popular online gambling activity in Europe accounting for 41% of gaming revenue, casino accounts for 34% and Lottery 15%.

In 2020, Europe accounted for 45.9% of the total online sports betting market, North America 25.5% and Asia 20.5%.

45% of sports betting was done pre-match and 55% in-play.

The sports betting figures could dramatically increase as more and more American states are moving to legalize sports betting. NBA commissioner, Adam Silver stated in 2014: “There is no solid data on the volume of illegal sports betting activity in the United States, but some estimate that nearly $400 billion is illegally wagered on sports each year.”
