Fairleigh Dickinson's stunning upset of Purdue in the first round of the men’s NCAA tournament busted brackets across the country, as the lowest-seeded team in the field defeated a team that had spent seven weeks this season ranked No. 1.

However, it also made one bettor very wealthy.

A bettor placed $33,000 on the Knights to defeat the Boilermakers at +1500 odds Friday evening, according to a Saturday morning tweet from Darren Rovell of The Action Network. The successful bet paid out an astonishing $528,000, a $495,000 windfall on one of the biggest upsets in the history of North American sports.

Before the game, Fairleigh Dickinson was a 23.5-point underdog to the Big Ten regular season and tournament champion. The upset was the largest by point spread in the history of the men’s NCAA Tournament—2.5 points more than the previous largest upset, by Norfolk State over Missouri in 2012, and 3.5 more than UMBC's legendary win over Virginia in 2018.
