The 2026 NCAA Tournament field is set with Duke, Arizona, Michigan and Florida earning No. 1 seeds. Here's a complete look at the championship odds available at BetOnline, with analysis on how the bracket shaped the market.
The Favorites
Duke (+325) enters as the No. 1 overall seed and betting favorite after a 32-2 campaign that included ACC regular season and tournament titles. The Blue Devils feature likely National Player of the Year Cameron Boozer but face injury concerns with starting point guard Caleb Foster and center Patrick Ngongba II.
Michigan (+350) sits just behind Duke despite being the No. 3 overall seed. The Wolverines' only two losses came by a combined four points, though they showed vulnerability in a narrow Big Ten Tournament championship win over Purdue.
Arizona (+400) has emerged as a popular pick after winning nine consecutive games, including dominant victories over Iowa State and Houston in the Big 12 Tournament. The Wildcats rank in the top five nationally in both offensive and defensive efficiency.
Florida (+750) carries the longest odds among No. 1 seeds after a blowout SEC Tournament semifinal loss to Auburn. The defending champions face a difficult South Region draw that includes Houston and Illinois.
The Contenders
Houston (+1000) leads all 2-seeds in pricing and will play regional games in their home city if they advance. The Cougars rank in the top 15 in both offensive and defensive efficiency.
Iowa State (+1400) and UConn (+2500) represent the remaining 2-seeds, with the Huskies drawing a difficult East Region alongside Duke, Michigan State and Kansas.
Illinois (+1800) is the shortest 3-seed after capturing the Big Ten Tournament championship.
Mid-Seed Value
Arkansas (+5000) leads all 4-seeds in championship odds and benefits from a relatively soft West Region draw. The Razorbacks are priced significantly shorter than fellow 4-seeds Alabama (+15000), Kansas (+6600), and Nebraska (+10000).
Notable Outliers
Alabama (+15000) stands out as a significant pricing anomaly. Despite being a 4-seed—the same seed line as Arkansas—the Crimson Tide are priced at triple the odds of their seed-line counterparts.
Lower Seed Longshots
Iowa (+30000) and NC State (+30000) share the shortest odds among teams seeded 7th or lower. Both teams must navigate the First Four in Dayton before entering the main bracket.
The championship odds remain fluid and subject to change as the tournament progresses. All wagers must be placed before March 26 at 7:30 PM ET.
