March Madness Odds 2025: Duke Stands Alone as Favorite With Bracket Set
Selection Sunday shook up the March Madness odds as the 2025 NCAA Tournament was set, but Duke remains the clear-cut favorite to win the national championship on Monday, April 7.
Duke, Florida, Auburn, and Houston were awarded the four No. 1 seeds in the 2025 March Madness bracket. As such, it's no surprise to see those same four teams leading the March Madness odds following Selection Sunday. Duke's market-best odds of +350 represent an implied win probability of 22.22% in the 68-team field.
The first round of March Madness begins Thursday, with the four First Four games played Tuesday and Wednesday to set the field of 64.

- Duke: Cooper Flagg is leading the Wooden Award odds, and seemingly avoided an injury scare after he left Thursday's ACC quarterfinal against Georgia Tech; he's expected to be on the court when Duke opens its tournament play on Friday
- Auburn: The Tigers closed the regular season with back-to-back losses to Texas A&M and Alabama, but that didn't stop Auburn from earning a No. 1 seed
- Florida: Closing the season with wins over Texas A&M and Alabama after beating Auburn a few weeks ago helped earn the Gators a No. 1 seed
- Houston: A defensive juggernaut, the Cougars' only loss since early December was to Texas Tech, and they earned their revenge while notching an eight-point win on the road in a rematch

😈 Duke March Madness odds (+350)
Flagg is positioned to potentially become just the fourth true freshman to win the Wooden Award, and he's expected to be the No. 1 pick by the NBA draft odds. That's why Duke was beginning to look like the team to beat before its loss to Clemson.
But the Blue Devils have bounced back in a massive way while recording eight straight 13-plus-point wins to close out the regular season. The biggest flex was when Jon Scheyer's team tallied a 43-point triumph over Illinois at Madison Square Garden, proving that Duke can win a title even with a freshman-heavy lineup.
What makes Scheyer's squad so dangerous is that it's not just Flagg carrying the load, as Kon Knueppel and Tyrese Proctor are two of the top ACC players. In a down year for the conference, Duke is poised to finish strong and make a March run that could lead to a $10 bet paying a $35 profit at BetMGM if the Blue Devils win the NCAA Tournament.
Duke's odds to win the NCAA Tournament settled back to +350 after Flagg seemingly avoided Thursday's injury scare:

🐊 Florida March Madness odds (+425)
It's safe to say that Duke, Auburn, and Houston have been the best teams this campaign while leading a conference for a reason. But after those three it's hard to argue against Florida and Alabama at least being the next two teams nobody wants to play in March because of the offensive prowess being trotted out.
The Gators have really been turning it on over the last month outside of a loss to Georgia, a stretch that includes wins over Auburn, Texas A&M, and Alabama. The foursome of Walter Clayton Jr., Alijah Martin, Alex Condon, and Will Richard will be one of the most lethal in the NCAA Tournament. Earning a No. 1 seed in the NCAA Tournament moved the Gators to second on the March Madness oddsboard.
Best odds: +425 via bet365 | Implied probability: 19.05%

🐯 Auburn March Madness odds (+500)
The top-ranked offensive team according to KenPom, Auburn survived while Broome was on the mend, and now he's back in full force. Arguably the best two-way player in the country, Broome had Auburn looking unbeatable against Alabama and Kentucky before falling to Texas A&M and the Crimson Tide in a rematch over the final two regular-season games.
While those were two tough losses to stomach, the Tigers were bound to lose a handful of games in an SEC conference many believe to be the toughest ever. With Broome playing dominant basketball, and Auburn featuring five other players scoring in double digits, this is the most battle-tested team in the country.
If the talent around Broome - like Tahaad Pettiford and Chad Baker-Mazara - can continue to complement him and carry Bruce Pearl's team to a title, a $10 winning bet on the Tigers pays a $50 profit at BetRivers.

🛑 Houston March Madness odds (+700)
Houston has been locked in over the last two months after a bit of a slow start. Kelvin Sampson's squad showed it was ready to compete for a title when it went into United Supermarkets Arena and managed a 69-61 win during a rematch against Texas Tech after the Red Raiders beat them on Feb. 1 to end Houston's 13-game winning streak. That came after beating Iowa State, too.
The Cougars are top 10 in both offensive and defensive efficiency, and they boast an eight-deep lineup made up of fierce defenders and versatile scorers. With LJ Cryer and J'Wan Roberts leading the charge, the Cougars hold a shot to win the NCAA Tournament, which would turn a $10 bet into an $70 profit. Houston is clearly the third-best team in the country right now.

💡 How to bet on March Madness
First, pick a reputable sportsbook among our best March Madness betting sites. Check out the odds for various teams; for example, if Duke is at +500 and Gonzaga is at +800, Duke is more favored to win. Decide how much you want to wager and place your bet. If you bet $100 on Duke at +500 and they win, you’ll get $600 back ($500 profit + $100 stake). Use the March Madness betting promos to get the most out of any wagers on the NCAA Tournament winner.
Now, why do odds move in future markets? It's all about performance and perception. If a team starts performing better or worse than expected, their odds will shift. Injuries to key players can significantly impact a team's chances and their odds. Changes in team dynamics, coaching, or even new player acquisitions can also affect odds. Public betting trends play a role too; if many people are betting on a particular team, sportsbooks might adjust the odds to manage their risk.
Expert analysis and predictions can also sway public opinion and betting patterns. Understanding these factors helps you make smarter bets and potentially catch favorable odds shifts.
