Live betting on March Madness

Also known as in-game betting, live betting affords the chance to hedge your initial position if a game breaks differently than you were expecting, or you can just wager on a standalone basis. Offerings will vary but may include the following:

If you like staying engaged as a game plays out, then live betting could be an area to explore. For those who prefer to place their wagers and then relax and enjoy the game, this style of betting might not be for you.

Recommended march madness websites for live betting

Depending on where you are located your options will change for what is available to you. With that being said, bet365 Sportsbook is known for being the leader in live betting in the United States. Bet365 offers a wide range of markets when it comes to in-game betting, and they also provide real-time updates.

On bet365, users can tune in and watch a live stream of a game they have wagered on as well, giving users more reason to come play on their app.

How we rank the best March Madness betting sites

We look at multiple factors when ranking the best betting sites for March Madness. Obviously, the sportsbook must be legal and regulated in the states where it does business. Once we’re assured on questions of safety and accessibility, we evaluate the player experience and overall usability.

The available menu of March Madness betting options is an important factor. Bettors should have a full selection of March Madness bets to choose from, with options for all the types of wagers that are legally available. The sportsbook’s odds and lines should also be competitive with the overall betting market.

Other important factors include the performance and usability of the sportsbook’s app and website, current bonuses and promotions, banking options, and customer service. Bettors should receive prompt and clear replies if any problems arise, and there should be a range of payment options to choose from so that users can make deposits and withdrawals quickly and easily.

Desktop and mobile performance can vary widely among online sportsbooks. While some offer a consistently smooth experience, others still have bugs to sort out. Finally, we review the terms, conditions, and playthrough requirements of all promotional offers to provide a full understanding of what they entail and what the restrictions may be.

Is betting on March Madness legal in the US?

Yes, in some places. To date, 30 states, plus Washington, DC, have legalized online sports betting, and the list will likely continue growing in the coming years. In 2018, the US Supreme Court overturned a federal ban on sports betting and placed the decision of whether to allow the activity into the hands of individual states. While sports betting has since become legal in many states, there hasn’t been any federal legislation across the entire US.

Rules and regulations for March Madness betting

States can set their own rules for sports betting. That means the rules can vary in states where betting is legal. All states prohibit those with close ties to a sport from wagering on it. Some states, however, have set the legal sports betting age at 18, while most have it at 21.

Rules for wagering on college sports can vary from state to state. The following states and other jurisdictions have no major prohibitions or restrictions on college basketball betting:

Meanwhile, others do have some regulations that deal with wagering on college sports.

How to bet on March Madness online

Within a matter of minutes, you can be set up and ready to bet on the next NCAA basketball tournament. Here are the steps to follow:

  1. Choose a legal online sportsbook. Depending on where you live, there may be multiple options to choose from for a major event like the NCAA basketball tournament.
  2. Review the rules. You must be of legal gambling age in your state and meet the eligibility requirements to sign up. If you’re claiming a March Madness bonus at sign-up, make sure you’ve read the terms and restrictions.
  3. Create an account. You’ll need to fill out some personal information and possibly verify your location. This will only take a couple of minutes.
  4. Add money to your account. Choose from the available deposit methods and use one of them to put money into your account. Some sportsbooks will offer a bonus depending on the amount of your first deposit.
  5. Decide what you want to bet on. There are multiple options when it comes to wagering on the March Madness tournament, from moneylines to point spreads and more. Betting options may vary by state.
  6. Choose your stakes. It’s up to you to decide how much to wager on any given bet, but there are two good rules to always keep in mind: Bet with your head and never over it, and never wager more money than you can comfortably afford to lose.
  7. Place your bet. If you find a bet you like, click the March Madness odds and enter the amount of your wager. Double-check to make sure everything looks good before you finalize the bet.
  8. Withdraw your funds. If you win, the time between winning your bet and receiving your winnings can vary, depending on whether you’ve chosen a fast-paying sportsbook. For most payment methods, you can expect anywhere between a few hours to three business days before you receive your money.

How March Madness betting works

You can bet on the winner of March Madness nearly year-round thanks to the futures market. Additional options include betting on teams to make the Elite Eight or Final Four.

For now, let’s focus on how you can bet on each individual game as the tournament plays out. From the First Four to the national title game, there are 67 games over multiple weeks. The average listing for an individual game will look something like this:

Baylor+188+5 (-110)Over 160 (-110)
Gonzaga-245-5 (-110)Under 160 (-110)

If you look next to the two team names, the default listing features the odds and lines for three main bets: the moneyline, point spread and total. Negative odds indicate a favorite, while positive odds indicate an underdog. In our example, Gonzaga is the favorite on the moneyline and a five-point favorite on the spread in a game with an over/under line of 160 total points.

Spreads and totals have the number that oddsmakers have set — in this case 5 and 160 points — followed by the actual odds for the wager, which are -110 across the board for our example. Here are the basics for all three wagers.

March Madness prop betting

Prop betting is another popular item on the wagering menu. These are bets that involve things that might or might not happen during a contest or at its conclusion. As mentioned earlier, individual states might have restrictions in place for college props, so be sure to review the rules in your area. Here are some examples of props you might see:

Props on college athletes aren’t available everywhere, so the options can be scant in comparison to what you would find for an NBA game. When checking the game listings at online sportsbooks, you can find the available props by clicking on the individual contests.

How to bet on March Madness futures

Odds for the winner of the next national championship will come out soon after the tournament is over. The board typically appears in descending order with favorites on top. The odds for a few favorites might look like this:

After the initial release, bets will begin coming in. The numbers will move in response to betting action. The teams that see a lot of interest can see their odds shorten, while the opposite can happen for squads that don’t attract as much attention. This will continue throughout the season as the betting market develops.

March Madness 2026 futures odds

Futures odds are available for the 2026 edition of March Madness. The live odds feed below contains the latest numbers from legal sportsbooks. If you see a bet that you’re interested in, just click the odds to be directed to the sportsbook to place it.

March Madness sports betting companies to steer clear of

Due to the nature of online sports betting in the United States, there are some players in the game that operate as offshore sportsbooks. We do not recommend using any offshore or grey market sports betting site or online casinos. If you are located in the US, you should be using legal, regulated online sports betting sites. Below is a short list of common sites to steer clear of:

March Madness 2026 date, time, and locations

The 2026 edition of the NCAA Division I Men’s Basketball Tournament is scheduled to begin on March 17 and wrap up on April 6. In between, it’ll be three weeks of action. Here are the key dates:

Lucas Oil Stadium in Indianapolis, Indiana, is the host for the Final Four and the title game. CBS and Turner Sports will be the broadcast home for the tournament, with games on CBS, TNT, TBS, and truTV, as well as on their digital platforms.

Which teams have performed the best at March Madness?

Each college basketball season is a separate event. Still, some programs have fantastic overall track records at March Madness. Here are the five clubs that have played the most games in the annual tournament:

The same five teams also top the charts in a number of other March Madness categories:

While the past is no guarantee of future success, there’s a good chance that the programs that have lengthy March Madness résumés will continue adding lines as we move forward.

March Madness brackets

In the world of sports, one of the biggest highlights of the early part of the year is the official unveiling of the March Madness bracket. The NCAA Division I Men’s Basketball Committee sets the field. Thirty-two teams receive automatic bids for winning their conferences, while 36 spots go to at-large schools for a total of 68 teams.

When setting the field, the committee will consider the overall record, the strength of schedule and various other performance metrics and stats. Determining which teams qualify is only part of the job. The committee also seeds the teams and sets the matchups. The bracket has four regions — East, Midwest, South, and West — and the winners of each then advance to the Final Four.

Each region has 16 teams, seeded from 1-16. The committee sets 60 seeds prior to release, while the final spots go to the winners of the First Four games. The tournament is single-elimination. Here’s how that translates into games for each round.

All told, it’s 67 games from start to finish. The committee does the heavy lifting in advance of the tournament, and there is inevitably a good amount of debate about which teams were snubbed for selection.

The odds of picking a perfect bracket correctly are 1 in 9.223 quintillion, according to the NCAA.
