What does -150 mean in UFC betting?
A -150 price means the fighter is the favorite: you must wager $150 to profit $100. Flip it around and a +130 underdog pays $130 profit on a $100 bet. The gap between those two numbers is where the sportsbook's vig lives. For a full walkthrough of American odds format, see how to read UFC fight odds: American moneylines decoded.

How does a UFC parlay work?
You combine two or more fight outcomes on one ticket; all legs must win for the parlay to pay. Payouts scale multiplicatively, but so does the sportsbook's edge — every added leg compounds the vig.

Closing line value (CLV) means getting better odds than the final price posted before the fight starts.
