When to Bet March Madness

It can be hard to digest the entirety of the NCAA Tournament. Consider the NFL as a comparison. The regular season has 256 games spread over 17 weeks. March Madness, on the other hand, has 63 games over three weeks, not including the four play-in games. It can be helpful to divide the tournament into three stages to get a better understanding.

The Round of 64 and 32

The first week of the tournament is the most chaotic. There are 32 games played during four days which means upsets, close escapes, and plenty of drama, in addition to some power teams dominating outmatched opponents.

Prior to the opening Thursday of the tournament, examine all of your future and prop options and fill out a bracket or two. With 32 games, you will be sure to find some good conventional wagering opportunities as well.

The Sweet 16 and Elite 8

By the time the second weekend of the tournament arrives, there are just 16 teams remaining, the Sweet 16. Thursday and Friday feature four games each while Saturday and Sunday are doubleheaders to get us from an Elite 8 to the Final Four.

One or two or three Cinderella’s are likely to come alive the second weekend, but these games tend to be Top 25 teams who are serious National Title contenders. Plenty of people fill out revised 16-team brackets and reconsider their futures and prop plays at this stage.

Having watched the first 32 games, you might have a stronger feeling about how to bet on Sweet 16 games after seeing the teams play a couple of times the previous weekend.

The Final 4

A semifinal doubleheader on Saturday and a championship game Monday night conclude March Madness. When it is all over a three-minute montage, celebrates the highs and the lows of March Madness.

Betting the Final Four is more conventional, just three games. However, think about it like the NFL Championship Weekend. This is like the AFC and NFC Title Games, and then the Super Bowl. It is fun to parlay the two semifinal games plus there are numerous props that are available for each game. Because this is a big stage, and a ton of focus is dedicated to these games, the wagering options are endless.

March Madness Betting Strategy and Tips

For those wondering how to bet on March Madness, we’ll run you through the basics here. Because there are so many games and a huge variety of ways to bet on March Madness, to some degree you need an understanding of where you feel like you have an edge and what sort of wagers you feel most comfortable with.

It is important that you fully understand how the bracket works, consider a variety of bets and tactics to handicap including stats and trends and manage your bankroll responsibly.

With the March Madness odds in hand, you are ready to learn some vital March Madness betting tips, strategies, and advice. We will lay out these important tips, which help you navigate Final Four betting odds and make the best March Madness bets.

Bracket Betting

After play-in games are completed 64 teams enter the main bracket of the Big Dance. The teams with the four best resumes get number one seeds and they are placed in regional brackets. Let’s take a look at some examples of March Madness bracket betting:

For example, if Duke is the number one team in the country, they will be the number one seed in the South Region. If Michigan State is the second-best team, they will be the top seed in the Midwest. If Kentucky is the third overall seed, and they can’t be in the South because Duke has already claimed that spot, they will be the top seed in the East Region (which would be closer than the West). Whoever is number four overall will they take the top spot in the West.

The next four best teams are the number two seeds. If Syracuse is deemed to be the fifth-best team in the land, they are the top number two seed and will be the number two seed in the East Region. If North Carolina is number six, they won’t go into the South Region because they can not play a conference rival, Duke, until later in the tournament, so they would move to the Midwest (since the East is not available and West is further geographically).

By ranking the 64 teams in the main draw, the teams with the best resumes are number ones, and the worst are 16-seeds. The one seeds meet the 16’s in the first round and then the winner of that game plays the winner of the eight-seed vs nine-seed game. The two seeds meet the 15’s with the winner playing the victor of a 7 vs 10 seed contest. Three seeds match up with 14 seeds and in the Round of 32, they take on the 6/11 winner. Four’s play 13’s and in the next round, they meet the winner of 5/12 games.

Say there is a number three seed that has a good reputation, but you don’t particularly like it. A good Cinderella team to be would be the team that they play in the opening round. Conversely, before you pick a Cinderella, make sure their matchups are conducive to an upset.

Underdog Approach

This may sound counterintuitive, but you can actually make a profit by betting exclusively on teams that are favored to lose. How is that possible? It is possible because when the underdog wins, the bet slip is worth much much more than when the favorites win.

Of course, you should not bet blindly on teams that everyone expects to lose. Rather, you should find undervalued underdogs. If you think the game is actually much closer than the bookies do, then it is a good underdog bet to place. Whether looking at Final Four odds or earlier in the competition, this strategy remains valid.

Bankroll Management

Because it is such a long competition, it is vital to have a clear plan for managing your bankroll. In bankroll management, you stabilize how much you risk so that you can analyze and adjust your March Madness betting strategy as the competition goes on.

One approach to bankroll management is unit-based. In this approach, you always risk the same amount no matter what. By keeping your risk stable, if you just look at your cash in-flow, you will be able to analyze the success of your bets.

Whether you’re a supporter of Ohio State or Oklahoma, UCLA or Virginia, our chosen sportsbooks provide the tools for making smart March Madness bets, catering to fans of NCAA and NBA alike, not to mention the fervent NFL enthusiasts.

March Madness Betting Trends

The media makes a lot out of the fact five seeds can be vulnerable. You will hear constantly about who the 12 seed that is going to beat a five seed is. There is a reason for this. A 12 seed has beaten a five seed in 30 of the last 35 tournaments, as it even happened in three instances in 2019 with Liberty over Mississippi State, Murray State over Marquette, and Oregon over Wisconsin.

As much as we like to pick against the favorites, a number one seed has won the NCAA Tournament in three straight years and 10 times in the last 13 brackets. The number one seeds have lost a first-round game just once when Virginia fell to UMBC in 2018. However, one seed have dropped second-round games on 19 occasions.

As for Cinderellas, since George Mason broke through and made the Final Four in 2006, we have seen others accomplish the feat: Butler (2x), Wichita State, VCU, and Loyola-Chicago. Based on the fact that no small school has cut down the nets since UNLV in 1990, it might be advisable to play futures on teams reaching the Final Four and not winning it all.

That being said if you find the right team and the odds are juicy, you never know what might happen. A team like Davidson College that had Steph Curry came a shot away from the Final Four, and who is to say if they hadn’t lost to Kansas that they wouldn’t have won it all?

How to Manage Your March Madness Bankroll

Like any time you bet, the best approach is a measured and well-thought-out one. It is not particularly effective to randomly place $20 on one bet and $150 on another. Generally, it is worthwhile knowing how much you want to place on various types of bets, sides, totals, and individual game options vs. futures and props.

Remember that certain bets, win or lose, will tie up your bankroll for the entire tournament, while others can be cashed out in two hours or less. Props and futures can be fun, but make sure that you are betting with conviction.

It is usually good to adjust your betting percentage based on results. Say you are planning to bet 4% of your bankroll on each wager you make. If this system is working, account for each win to slightly increase your ROI, but when you lose scale back slightly. Remember, it is a marathon, not a sprint.

Team Analysis 2026

When you conduct team analysis, you will be well-positioned to find and exploit undervalued bets. This means identifying underdogs that are likely to win, or at least less likely to lose.

So how? How can one get to the bottom of this? Well, you have to keep some things in mind when you are looking into potential upsets and making your March Madness bracket.

Here are five things to keep in mind when conducting your team analysis for March Madness 2026:

• Injury reports – Are key players out and who is their replacement?
• One-to-one matchups – Who will be controlling the other team’s dominant players?
• Expect some upsets – 12.2 on average during the tournament, in fact
• Keep in mind relative fatigue – lower seeds face strings of tough games
• Never underestimate free throws – these make the difference more often than you think
