UFC betting line odds are the most popular on the big marquee events like UFC 86. There are also UFC odds on title and non-title fights.
If you want to win money versus the UFC line you need to understand it and how it is made. UFC betting line odds are money line based which means you will have a favorite and an underdog. It is just like what you see in baseball, NASCAR, golf, tennis, soccer, hockey, etc.
You only worry about your fighter winning, there is no pointspread. How is the UFC line made? The marquee and well known fighters are usually favored and depending upon their popularity you might see them at UFC betting odds of 2-1 or more. If you want to win money versus the UFC betting line then you need to have an idea if the UFC betting odds are fair.
That means you need to make your own UFC line so you understand what the odds should be. It is not that difficult to do. Once you set your own UFC betting line you can check it versus the sportsbook and see how close or how far off you are. If you see a major difference check into that fight and see if a wager is warranted. You may also want to check the UFC betting line for movement and see if it is moving in favor or against the line you set.
To make your own UFC betting line you need to do some research. This means you look at each fighter, their records, their style, previous opponents, etc. If you can watch previous fights that can also be helpful when making your own UFC betting line. Once you have looked at all of this data you can try and project how the fight should go and then determine where or not you should make a play versus the UFC betting line.
If you are looking at over/under options in UFC betting you can also consider how long the previous fights of each fighter have gone. If you have a proposition wager on how the fight will end (decision, knockout, submission) then you can research how each bout in the past has ended. The more research you do on the UFC and the fighters, the better your chances of success will be.
