4 Minute ReadNCAA National Championship Odds: Arizona, Michigan, Duke Continue to Lead Title Odds After Florida Upset
The first four days of March Madness did not deliver total bracket chaos, but they did give us one major shakeup at the top. Defending champion Florida was stunned by Iowa on Sunday night, preventing all four No. 1 seeds from reaching the Sweet 16 and opening up one side of the bracket in a way few expected.
Even with Florida out, the title picture still looks top-heavy. The betting board and the on-court results both point to a small group of legitimate championship contenders. At this stage, it is increasingly difficult to make a serious case for teams outside the elite tier because of either a talent gap, a defensive weakness, or an offensive ceiling that does not quite match the favorites. Here is where the top seven contenders stand entering the Sweet 16.

National Championship Odds Breakdown
(1) Arizona Wildcats (+330) Click here to get the best National Championship odds on Caesars Sportsbook
Arizona has emerged as a co-favorite to win the national title at +330 after handling its first two games with the poise you expect from a No. 1 seed. The Wildcats opened with a 92-58 win over Long Island and followed it up with a 78-66 victory over Utah State to reach the second weekend.
Now Arizona gets Arkansas in the Sweet 16, where the Wildcats are -355 on the moneyline and 8.5-point favorites. That is a dangerous draw because Arkansas is talented enough to push them, but Arizona’s combination of depth, defense, and star power has kept them near the top of the board all season. If they survive that one, the Wildcats look like the strongest remaining team in the West.
(1) Michigan Wolverines (+330) Click here to get the best National Championship odds on Caesars Sportsbook
Michigan shares the top spot on the board at +330 and has looked every bit like a title favorite through two rounds. The Wolverines crushed Saint Louis 95-72 in the Round of 32 after moving cleanly through the first weekend, and their offensive ceiling continues to look as high as anyone’s left in the field.
The next test is Alabama, and Michigan is a -500 moneyline favorite and 10.5-point favorite in that Sweet 16 matchup. Alabama has enough scoring to make this uncomfortable, but Michigan’s balance and interior dominance have made them one of the safest teams in the bracket. If the Wolverines get through the Crimson Tide, they will be very difficult to stop.
No. 1 Duke Blue Devils (+450) Click here to get the best National Championship odds on Caesars Sportsbook
Duke is now sitting at +450 after a dominant opening weekend that reaffirmed its status as one of the most complete teams in the country. The Blue Devils rolled into the Sweet 16 with an 81-58 win over TCU in the second round and continue to defend at an elite level while getting star production from Cameron Boozer.
The Blue Devils face a dangerous St. John’s team next, but they are still -305 on the moneyline and 7-point favorites. St. John’s is hot and physical, but Duke’s blend of defense, rebounding, and top-end talent still makes them the clear favorite in the East. If they move on, they remain one of the strongest bets on the board.
(2) Houston Cougars (+700) Click here to get the best National Championship odds on FanDuel Sportsbook
Houston remains firmly in the championship mix at +700, and the Cougars looked sharp in the second round with an 88-57 blowout win over Texas A&M. Their defense is still one of the best in the country, and when their offense is efficient enough, they look like a team built to grind through March.
The Sweet 16 matchup against Illinois is one of the best games of the round. Houston is -164 on the moneyline and 3-point favorites, which reflects how much respect the market still has for the Cougars. The challenge will be scoring enough against an Illinois team that can pressure them offensively, but if Houston controls pace and turns it into a half-court game, they have the edge.
(2) Purdue Boilermakers (+1400) Click here to get the best National Championship odds on FanDuel Sportsbook
Purdue has quietly shortened to +1400 after entering the tournament hot and continuing to look dangerous through two rounds. The Boilermakers are still powered by their veteran backcourt and the nation’s most efficient offense, and the confidence from that late-season Big Ten title run has clearly carried over.
Their Sweet 16 game against Texas is one they are expected to win, with Purdue listed at -295 on the moneyline and 6.5-point favorites. Texas is capable of making things interesting, but Purdue’s offensive consistency and guard play give the Boilermakers a strong path to the Elite Eight. If they get there, they start to become a very live title threat.
(3) Illinois Fighting Illini (+1500) Click here to get the best National Championship odds on FanDuel Sportsbook
Illinois enters the Sweet 16 at +1500, and that number makes sense because the Illini have looked like one of the best non-No. 1 seeds in the field. They beat VCU 76-55 in the second round and continue to flash one of the most explosive offenses left in the tournament.
The problem for Illinois is that the path is brutal. They now face Houston and are +136 on the moneyline as slight underdogs. If they win that game, the likely reward is another heavyweight battle. Still, with the way Illinois scores and the star power they bring into every game, they are absolutely capable of winning this region if they get hot for two more nights.
No. 2 Iowa State (+1700) Click here to get the best National Championship odds on Caesars Sportsbook
Iowa State rounds out this group at +1700, and the Cyclones remain one of the more balanced teams left in the field. Their defense travels, they take care of the ball, and they are exactly the kind of group that can grind out ugly tournament games when possessions get tight.
Their Sweet 16 matchup against Tennessee is a good test, but the market still leans Iowa State with the Cyclones -190 on the moneyline and 4.5-point favorites. Tennessee is dangerous, but Iowa State’s discipline and turnover advantage make them a very real threat to keep advancing. If they reach the Elite Eight, they are right there with the second tier of contenders.
