What a UFC Moneyline Actually Tells You
A moneyline price is expressed as a positive or negative number. A negative number — say -180 — means you'd need to wager $180 to collect $100 in profit; that fighter is the favorite. A positive number — say +155 — means a $100 wager returns $155 in profit if that fighter wins; that's the underdog. The gap between the two prices
is the house margin. In UFC, upsets happen more often than in team sports, so the spread between favorite and underdog prices can shift sharply in the days before a fight. Checking the line closer to fight night often shows meaningful movement driven by public money and late news like weight-cut reports.
