Conor McGregor’s long-awaited UFC return ended in dramatic and unexpected fashion, creating one of the biggest sportsbook wins tied to a major MMA event in recent memory.
The UFC 329 main event against Max Holloway lasted just 69 seconds before McGregor suffered a knee injury that left him unable to continue. What had been promoted as a blockbuster comeback after more than five years away from the Octagon quickly turned into a disappointing finish for many fans and bettors.
McGregor opened the fight aggressively, charging forward with a jumping kick. However, he appeared to injure his knee almost immediately after landing. Despite attempting to continue, the damage was evident, and the bout was stopped shortly afterward, awarding Holloway a first-round TKO victory.
For viewers, the ending was anticlimactic. For sportsbooks, however, it delivered a highly favorable outcome.
Although Holloway entered fight night as the betting favorite, McGregor remained the more popular choice among recreational bettors. His star power, history of generating excitement, and reputation as one of the UFC’s biggest attractions attracted significant wagering interest across the market.
According to reported sportsbook data, McGregor became one of the most heavily backed fighters in betting history for a UFC event.
At BetMGM, all three of the top UFC 329 prop bets centered on McGregor. The most popular prop was McGregor to win by KO/TKO at +275, while McGregor by submission at 25/1 ranked third in ticket count and McGregor by decision at 14/1 came in fourth. According to DraftKings, McGregor attracted 92% of the total money wagered on the fight and 68% of all bets placed on the outright winner market. His KO/TKO outcome alone accounted for 30% of all prop tickets and 34% of the total handle.
Many fans believed the former two-division champion could complete a successful comeback despite his lengthy layoff and previous injury issues.
That imbalance in public betting created an unusual situation. While sportsbooks respected professional action backing Holloway, many casual bettors continued to place wagers on McGregor. As a result, operators carried considerable liability on a McGregor victory heading into the fight.
When Holloway was declared the winner, those concerns disappeared almost instantly.
The event itself was still a commercial success, generating major attention and a record-setting gate despite the disappointing conclusion to the headline fight.
Questions now shift toward McGregor’s future. At 37 years old and dealing with another serious injury setback, uncertainty surrounds whether he can make another comeback. UFC officials and fans will await medical evaluations before any long-term plans become clear.
For sportsbooks, however, the story is far simpler. One of the most heavily bet fighters in the sport suffered an early defeat, and the result produced a favorable outcome for operators across the betting industry. In a fight that lasted barely more than a minute, sportsbooks secured one of their most significant victories of the year.
