Odds To Win The 2021 NCAA Men's Basketball National Championship

Each year, sportsbooks will roll out money line odds for which team will win the March Madness Tournament and become the men's basketball national champion. These March Madness money line odds indicate how much can be earned by betting on them, and what their odds of winning are.

Since there are so many teams included in the betting line, even the most favored team will be listed with positive odds, meaning that there'll be a payout higher than what bettors risk no matter which team they select.

The NCAA Division I Men's Basketball Championship betting odds featured below is on the boards all year, and typically gets posted at legal NCAAB sportsbooks right after the national champion is crowned for the previous season. The only downside is that bets can take months to payout.

How To Bet On March Madness?

As discussed previously, US bettors that want to know how to bet on March Madness can visit a domestic sportsbook or wager at one of the international college basketball betting sites we recommend in this guide.

Individual game bets allow for action to be placed on point spreads, money line winners, over/unders, prop bets, and even allows for live bets to be placed in-game. While not exactly betting, the most popular option for predicting March Madness results is completing brackets where each fan attempts to attain a perfect bracket. It's never happened, but if and when it does, the winner will earn a hefty payday.

Tips For March Madness Betting

Bankroll management is a priority when declaring your March Madness betting strategy because there are so many games that funds can get depleted quickly. Declare a budget for March Madness betting odds and ensure that it is sourced from disposable incoming - meaning assets remaining after all bills have been paid.

Set a betting limit of 3%-5% of your total bankroll for each game. This will allow at least 20 bets to be made, assuming all of them fail, which is not a likely outcome. It will keep bettors from making hasty wagers and will keep gamblers in the action much deeper into the tournament.

We also suggest belonging to more than one sportsbook because odds are different at each site. If the Duke Blu Devils are favored by 10 at one book and by 12 at another, selecting the line that favors them by 10 will provide an easier path to a win. Being mindful of these three bankroll management strategies will go a long way toward maximizing
