Conor McGregor made headlines with a $1 million bet on Alex Pereira's victory at UFC 307, which netted him $200,000 after Pereira's fourth-round TKO of Khalil Rountree Jr. McGregor expressed admiration for both fighters, praising Rountree's performance despite his loss and suggesting he's still a title contender. The event was marred by criticism of the judging, notably Dana White's dissatisfaction with the decision-making, particularly in the Jose Aldo vs. Mario Bautista fight, which ended in a controversial split decision favoring Bautista. McGregor and others, including Joe Rogan, voiced their disagreement with the decision, highlighting Bautista's strategy of stalling tactics. Despite the controversies, UFC 307 was praised for its exciting fights, especially the main event, which demonstrated the high caliber of MMA action.
