Who doesn’t love a good upset?
In 2023, MMA saw its fair share of underdogs who defied the odds in the UFC, Bellator, PFL, and beyond. While everyone has an opinion of who should win and who should lose, the oddsmakers (and how the betting public responds) largely get the final say on what history reflects.
This year, with the help of MMA database Tapology, MMA Junkie has compiled the top 10 betting upsets of 2023. Fights that were eligible were those that multiple major online sportsbooks recognized, and that Tapology recorded before the close of the betting line.
Promotions eligible include UFC, Bellator, PFL, KSW, DWCS, Road to UFC, and ONE Championship.
Check out the top 10 MMA betting upsets of 2023 below. Only major MMA promotions were included in the tally.
