In the United States, the most prolific sports betting activity takes place during the NFL football season. With legal sports betting relatively recent in the U.S., a report by Kambi on the recently completed NFL season demonstrated that NFL bets were the first bets placed by over half of the new signups over the past year. College football (NCAA) hovered around 20 percent of the first bets. But those new bettors quickly realized that they could bet on the other major sports leagues in the U.S. As the chart below shows, bettors moved on to wager on all six of the major sports leagues in addition to the NFL—NHL, NBA, NCAA football, NCAA basketball and Major League Baseball. The report, which includes breakdowns on contending teams and betting patterns surrounding the Super Bowl, can be accessed at Kambi.com.
