Is it legal to bet on March Madness?

There is no prohibition against betting on March Madness in the United States and with the advent of legal sports betting in over 33 states, with more to come, many people now understand that offshore online sportsbooks offer better odds than most other popular sites.

The U.S. market does not regulate offshore sportsbooks and therefore can offer better lines, odds and bonuses than domestic sportsbooks. This is a noticeable advantage that the offshore sites enjoy and one that is passed on to the customers doing business with them. 

Popular March Madness Betting Markets

Understanding the various types of bets available can enhance your March Madness experience and potentially increase your chances of winning. Below is a list of the most popular types of bets during March Madness season.

  • Moneyline bets: the most common type of bet for March Madness. You simply pick a team to win. Odds are set by the sportsbooks, and your payout depends on these odds.
  • Point Spread bets: With point spread bets, a handicap is applied to the favorite team, making the game more balanced. You can bet on the favorite to win by more than the spread or the underdog to lose by less than the spread or win outright.
  • Over/Under (Totals) Bets: This bet involves predicting the total combined score of both teams in a game. The sportsbook sets a number, and you bet on whether the actual total will be over or under that number.
  • Parlays: These bets combine multiple bets into one. All your picks must win for the parlay to pay out, but the reward is higher odds and a bigger potential payout.
  • Futures bets: Bets placed on events that will happen in the future, like which team will win the tournament. The future odds change as the season progresses, offering different payouts at different times.
  • Prop bets: These are wagers on specific events within a game, not tied to the game’s outcome. Examples include betting on which player will score the first basket or how many points a player will score.

Each type of bet offers a different way to enjoy March Madness and can increase your engagement with the games. Remember to bet responsibly and consider your options carefully before placing your bets.

Popular Teams in March Madness 2025

As March Madness 2024 heats up, bettors are keeping a close eye on several teams that have grabbed headlines and are showing strong potential. Whether you’re new to betting or have been around the block a few times, knowing which teams are drawing attention can help you make informed decisions. Here’s a rundown of some key teams to watch this season.

1. The Defending Champions

Always a team to watch, the previous year’s winners come into the tournament with a target on their backs. They have the experience and the skills, having gone all the way before, but can they handle the pressure to repeat their success? Since UConn won March Madness 2023, they are a team to keep an eye on this year.

2. Top-Seeded Teams

The teams that secure the top seeds in the tournament are important to watch. They’ve earned their spots through strong performances in the regular season. These teams are often considered the favorites to go far in the tournament, if not win it all. The teams predicted to have the highest seeds are Houston, Purdue, UConn, South Carolina and Arizona. 

3. The Underdogs

Every year, there are a few lower-seeded teams that surprise everyone. These underdogs can upset the odds and make a deep run into the tournament. Betting on underdogs can be risky, but it can also lead to big rewards if they manage to pull off a few upsets.

4. Teams with Star Players

Teams that boast one or more star players are always in the mix. These players can take over a game and lead their team to victory, even against tough opponents. Keep an eye on teams with players who are having standout seasons or who can change the game in an instant.

5. Teams Peaking at the Right Time

Some teams might have had an up-and-down season, but if they’re hitting their stride as the tournament approaches, they could be dangerous. Momentum is a real factor in March Madness, and teams that are peaking at the right time can often outperform their seeding.

By keeping these teams in mind, sports fans can better navigate the complexities of March Madness betting. Remember, upsets are common, and the unexpected can and does happen. Use this information to guide your betting strategies, but always do your research and consider the latest news and analysis before placing your bets.

March Madness Online Sports Betting Promotions

NCAA March Madness brings out the biggest and best bonuses at online betting sites everywhere. Risk-free bets are one of the most popular bonuses to be found because they allow the customer a shot at all reward wagers without any risk.

You will also find a bracket contest at many of the online sportsbooks, some giving away $1 million for a perfect bracket and as much as $100,000 for the winning bracket. Best of all, these bracket contests are often free and part of their March Madness promotions.

New sign-ups will also find some books giving 125 percent of the deposit amount in bonus play. It is a buffet of free plays and big bonuses when you sign up for the biggest betting tournament in North America.

March Madness Betting Tips

Betting on college basketball games can be thrilling but also challenging. Here are some tips to help you make smarter bets during the tournament.

  • Understand the Odds: Odds tell you how much you can win on a bet. Lower odds mean a team is favored to win, but the payout is smaller. Higher odds mean a team is less likely to win, but the payout is bigger if they do.
  • Research Teams: Before placing bets, look at how teams have performed during the season. Consider their strengths, weaknesses and any injuries that might affect their play.
  • Don’t Overlook Underdogs: March Madness is famous for upsets. Sometimes, betting on an underdog can pay off. Look for teams that have been improving toward the end of the season.
  • Consider Betting on Multiple Games: Instead of putting all your money on one game, consider spreading it across multiple games. This approach can reduce risk and increase your chances of winning overall.
  • Pay Attention to Location: Games aren’t played on home courts. Some teams may perform better or worse in different locations. Check past performances to see how teams handle travel and unfamiliar venues.
  • Watch the Public Bets: Sometimes, the public heavily favors one team. This can skew the odds. If you have done your research and believe in the underdog, this could be a good opportunity to bet against the public.
  • Set a Budget: Decide how much you’re willing to spend on betting before the tournament starts. Stick to this budget to avoid any financial stress.

Remember, betting should be fun and not a way to make money. Use these tips to help guide your decisions, but always bet responsibly.
