McGregor’s ACL injury sustained in his first-round loss to Max Holloway at UFC 329 in July has left his 2027 return date and final UFC bout undetermined, creating broad uncertainty that keeps probabilities clustered across multiple options. With one fight remaining on his contract and McGregor publicly calling for a Holloway trilogy during International Fight Week, traders weigh that rematch alongside longstanding rivalries such as a Nate Diaz trilogy or Michael Chandler matchup. Recent comments from Diaz expressing interest in completing their series, ongoing recovery timelines, and speculation about a post-UFC move to bare-knuckle competition further fragment consensus, sustaining tight implied probabilities among leading contenders and “other” outcomes.
