Is It Legal To Bet On March Madness In The U.S.?

It is legal to bet on March Madness in the U.S. at licensed sportsbooks or those based offshore.

Best Legal Deposit Method For March Madness Betting

The best legal deposit method for March Madness betting is the Bitcoin cryptocurrency. Unlike credit cards – which are also a legal deposit method – Bitcoin transactions will not get declined. You can also enjoy more flexible deposit limits, ranging from $10 to $50,000 depending on the online sportsbook. When you bet on March Madness with Bitcoin, your funds will be credited to your account within minutes. Again, Visa, Mastercard, and American Express are also convenient deposit methods for American sports bettors (though it should be noted that not all of the top online sportsbooks accept AMEX). For cards, the deposit minimum is usually around $25 and the maximum amount will usually not be allowed to exceed $5,000. There may also be a small percentage fee charged by your card issuer.

Legal March Madness Wager Types

In order to start betting on any of the 68 teams competing in the NCAAB Tournament, you need to know the legal March Madness wager types. The single-elimination style NCAA Men’s Division I Basketball Championship presents plenty of opportunities for smart sports bettors to turn huge profits. The March Madness wager types are luckily the same as the bet types available throughout the regular NCAA basketball season, which reduces the learning curve. Here are the common bet types for wagering on March Madness:


When betting on NCAA Futures, you will be able to bet on the outright winner of March Madness. This type of bet is available on the odds board well before the official start of the NCAA Tournament. You will be making a bet on one team to win it all. In the outrights market, you will get the best value by placing your bets before your team starts to win games.

Point Spread

Each game will have a point spread posted, which is the number of points a team must win or lose by in order to win the wager. The favored (-) team must win by more points than indicated in the spread, while the underdog (+) must lose by less than the spread or win outright. For example, a game between North Carolina and Gonzaga may be posted with the following spread:

  • North Carolina -3
  • Gonzaga +3

If you were to back the favored North Carolina Tar Heels, the team would need to win by more than 3 points to cover the spread. For the Gonzaga Bulldogs to cover, they must lose by less than 3 points or win the game outright. If North Carolina won by exactly 3 points, the bet would result in a “push” and the wager would be refunded. This is why many sportsbooks post such spread bets with half-point increments. Note also that the moneyline, or price of the bet, is included in parentheses beside a spread bet. In this case, both sides of the bet require a wager at a ratio of $110 wagered to $100 won.


Betting on the total of a March Madness game is another wagering option. The oddsmaker will assign a total number of combined points to be scored by both teams, and you will wager on the total points to be over or under this number. This is why totals bets are commonly called “over/under” bets. Here is an example:

  • Mount St Mary’s - Over 132
  • Villanova - Under 132

For this totals bet, you can bet the “over” if you believe St. Mary’s and Villanova will combine to score more than 132 points. You can take the “under” if you believe the final score will be less 132 points combined. Again, many books will use half-point increments to prevent pushing, and the moneyline in parentheses shows the price/payout of the wager.

Money Line

Betting on the money line is a wager on the outright winner of a particular March Madness game. A moneyline bet is more often referred to as a straight bet or straight moneyline bet, given that moneylines themselves are a part of all wager types. With a straight moneyline bet, you don’t have to worry about the number of points put up or covering the spread. You’re just picking which team you think will win “straight up,” and the moneyline shows how much you stand to win. Take a look at the straight moneyline bet below on the Duke Blue Devils and the Kansas Jayhawks matchup:

  • Duke -150
  • Kansas +125

Here, the moneyline shows not only the bet’s price tag, but it also indicates which team is the favorite (shown with a – sign) and which is the underdog (shown with a + sign). If you were to bet on Duke at -150, you would need to wager $150 in order to win $100 should they take the W. If you were to bet on underdog Kansas for $100, you would see a return of $125. These aren’t betting minimums, by the way – they are merely ratios that show how much you stand to win per a given amount wagered. Most legal online March Madness betting sites will take individual bets of as low as $0.25.

March Maddness Proposition Bets

March Madness is one of the best times to bet props, especially when you see your bracket start to bust. NCAA Tournament props can cover a wide range of scenarios that can cover specific players, an entire team, or the game overall. You can find over/unders on the largest lead of the game, margin of victory props, over/under points and assists for a particular player, and more.

In many cases, March Madness prop bets will go completely outside the realm of a particular matchup and focus on scenarios related to the tournament. Here are some of the more popular proposition bets for March Madness, generally speaking:
