2026 SportsLine Upset Bracket Full of Surprises
SportsLine simulated every possible matchup 10,000 times and the team that won over half the simulations was selected to advance. In order to "simulate the madness," we also assumed that the Nos. 3-6 seeds with the lowest win percentage when compared to other teams of the same seed would be upset. With this approach, we've nailed 25 double-digit seed upsets in the first round!


Our proven projection model has simulated every 2026 NCAA Tournament game 10,000 times, just like in the bracket above. Last year, SportsLine's computer simulation nailed massive upsets, including calling both 9-seeds that advanced in the first round, No. 12 Colorado State over No. 5 Memphis, and No. 6 BYU advancing to the Sweet 16. The model has beaten over 91 percent of all CBS Sports bracket players in four of the past seven tournaments!
This model, which simulates every game 10,000 times, has nailed 25 first-round upsets by double-digit seeds since its inception in 2016 and nailed UConn's championship run last year. It nailed 12 teams in the Sweet 16 and correctly predicted all four Final Four teams a year ago.
