The resolution source for this market will be official information from the NCAA; however, a consensus of credible reporting may also be used.Trader consensus heavily favors a No. 1 seed national champion at 65% implied probability, propelled by Duke, Michigan, and Arizona all advancing to the Elite Eight via dominant Sweet 16 performances, including Michigan's 90-77 rout of No. 4 Alabama and Arizona's coasting win over Arkansas. #9 Iowa's landmark upset over No. 4 Nebraska—the first double-digit seed to reach this stage—has boosted that outcome to 8.2%, injecting upset potential into the bracket. #2 Purdue's narrow buzzer-beater escape against No. 11 Texas sustains 21.5% on 2-seeds, while No. 3 Michigan State's elimination by UConn tempers but preserves 22% trader support for 3-seeds amid chalk-heavy Elite Eight matchups like Duke vs. UConn.
