Not all fights have a favorite and an underdog. Some fights are “pick ’ems,” with the odds the same for both competitors. But of the 511 bouts to take place in the UFC in 2022, 486 had one favorite and one underdog. Of those, the favorite won 64.8% of the time. In 2023 and through the first few months of 2024, that rate has nudged up to 67%.
