People in North Carolina may have a little more riding on this year’s NCAA men’s and women’s basketball tournaments, as they will be able to legally bet on the games through their smartphone apps and computers for the first time.
For the sixth straight year, the number of states allowing legal sports betting has expanded since the last rendition of March Madness. A total of 38 states and the District of Columbia now allow some form sports betting, including 30 states and the nation’s capital that allow online wagering.
That’s up from one state, Nevada, where people could legally wager on games during the 2018 college basketball tournaments, before the U.S. Supreme Court cleared the way for expansion.
The rules for sports betting vary by state. Some states prohibit bets on home-state college teams or the performance of specific players. Others allow bets not only on the outcome of any college games but also on a variety of other things, such as the number of points, rebounds and assists that a particular player will tally.
Here are some things to know about sports betting as the tourneys open, with the men’s games starting Tuesday and the women’s competition beginning Wednesday.
Fans have long filled out NCAA tournament brackets while wagering in office pools or against friends and family. But those casual bets have increasingly been supplemented with more formal gambling.
The total amount bet on all sports through legal wagering sites exceeded $121 billion in 2023, up 30% from the previous year, according to the American Gaming Association. After paying out winnings, sports betting operators reaped $11 billion in revenue, up from about $7.5 billion the previous year.
The American Gaming Association estimates $2.7 billion will be bet this year on the NCAA men’s and women’s basketball tournaments through legal sports books.
“March Madness is the biggest kind of individual event of the year for sports betting,” said David Forman, the American Gaming Association vice president of research.
The Super Bowl also draws big bets, but it’s only one game between two NFL teams. The NCAA Division 1 men’s and women’s basketball tournaments feature a total of 136 teams playing 134 games over three weeks.
Despite living where sports betting is legal, some fans still could be blocked from betting on their favorite teams and players.
Roughly a dozen states bar bets on college games involving home-state teams. Four additional states — Connecticut, Massachusetts, Rhode Island and Vermont — generally prohibit bets involving their own college teams but make exceptions for tournaments.
Some states only allow bets on the outcome of college games, not how particular players will perform. Maryland and Ohio, for example, banned so-called proposition bets on college players, effective this month.
The NCAA has raised concerns that player-specific bets can lead to problems, including the harassment of college athletes and strain on their mental health. The organization also says such bets could entice players to wager on themselves or alter their play to affect stats-based bets.
Since the University of Connecticut won the men’s tournament last year, half a dozen states have launched or expanded sports betting.
Nebraska began taking sports bets at casinos last June, though it doesn’t allow mobile wagers. Kentucky launched sports betting in September to coincide with the start of the NFL season, and Maine began doing so in November.
After a court victory, the Seminole Tribe of Florida in December began taking online sports bets in addition to wagers at its casinos. Wagering has continued while a challenge is pending before the Florida Supreme Court. Opponents also have asked the U.S. Supreme Court to take up the case.
In January, Vermont launched online sports betting.
North Carolina, which previously allowed sports betting only at three tribal casinos, began permitting online sports wagering statewide on March 11, a day before the start of the popular ACC men’s basketball tournament but a day after the women’s tournament ended.
Several states have a chance to join the sports betting trend.
