UFC betting guide

As the sport of Mixed Martial Arts has grown, so too has the popularity of UFC betting. This MMA betting guide will help you to learn how to bet on UFC fights.

MMA has exploded in popularity over recent years, spawning a host of different competitions around the world. The leader is the UFC – the Ultimate Fighting Championship.

Legends of the UFC, guys like Chuck Lidell, Tito Ortiz, and Randy Couture helped launch the Octagon’s popularity back in the day, but it really exploded when the likes of Conor McGregor and Ronda Rousey took the sport by storm. 

And where there are fight fans, you’ll find bettors willing and wanting to put their money where their mouths are. 

With UFC pay-per-view events beamed around the world, millions are staked each week on UFC events. The number of people backing their favorite fighters is sky-rocketing. 

In the US, the legalization of sports betting is only whetting the appetites of hardcore fight fans and casuals alike.

With that in mind, The AllStar brings you a complete guide on how to bet on UFC fights.

How to bet on the winner of UFC fights

Favorite vs Underdog

When a sportsbook releases a betting line, it designates the favorite and the underdog.

  • The expectation is that the favorite wins; their odds will have a minus sign next to them. 
  • The expectation is that the underdog will lose; their odds will have a plus sign next to them.

These odds make up the fight’s moneyline.

UFC Moneyline betting

A quick explainer video about how the UFC moneyline market works

The moneyline identifies the favourite and the underdog, but the odds assign a value to each side. The size of the odds expresses the extent to which they are favored to win, or expected to lose.

Favorites, as we have seen, take a minus sign; underdogs a plus sign.

If a favorite is listed at -200 it means you have to wager $200 to win $100. If the favorite wins, you win $100, but if they lose, your $200 goes with them. Because favorites are expected to win, you assume more risk when you bet on them.

If an underdog is listed as +200 it means if you bet $100 and they win, you get $300 (your $100 stake and $200 in winnings (a simple but important breakdown when it comes to managing your bankroll). Because underdogs are not expected to win, there is a greater reward when you back them.

When looking for a sportsbook to play with, comparing the moneyline is an excellent gauge – though not the only consideration – of value. Generally speaking, it always pays to look for the best odds available, though be sure to also read all the sportsbook rules as they do differ from book to book.

The moneyline is sometimes casually called just “the line”; someone looking for the best odds is “searching for the best line.”

Sportsbooks that tend to consistently offer low-margin odds for the US gambling markets include DraftKings and BetMGM. 

What happens to my UFC bet if the fight ends in a draw?

Fights can end in a draw, no contest, or with a DQ (disqualification), although this is rare. Usually, a draw in a UFC fight results in voided moneyline bet – meaning you get your stake back. But be sure to read the MMA betting rules before placing a bet, as different bookmakers have different rules.

How to read UFC odds

The majority of the UFC’s viewership is based in North America, as are its broadcast team and partners. As such, you’ll almost always hear the likes of Jon Anik describe fight odds in their American format.

Example: Stipe Miocic (+120) vs Francis Ngannou (-145)

As we have learned, being at +120 makes Miocic the underdog. 

A $100 bet on a +120 underdog returns you $120. And as we also now know, at -145, that makes Ngannou the favorite. To win $100 by backing this favorite, you need to risk $145.

A quick introduction video explaining how to read american UFC odds

Odds reflect the expected outcome and illustrate the extent to which one fighter is favored over another.

A favorite at -400 is more favored to win than one at -300, who in turn is more favoured than one at -200. Similarly, an underdog at +150 has a perceived better chance of an upset than an underdog at +300, or +500. 

Line Movement – What are opening and closing fight odds?

Oddsmakers set the moneyline based on what they believe to be the probability of winning for each fighter. The first odds are the opening odds. As action comes in, the line adjusts to equalize the bookmaker’s risk, like a typical market governed by supply and demand. 

This is line movement.

When the cage door shuts, the final odds are the closing odds. If the gambling community reacts strongly against the opinion of the sportsbook, the closing odds can be wildly different to the opening odds.

Professional UFC bettors often buy the moneyline market early, locking in higher opening odds before the line moves.

If there was no line movement, sportsbooks wouldn’t exist because they wouldn’t be able to function as viable money-making concerns. Every business needs a business model! (See also the section on Vig below.)

Betting the Over/Under in UFC

Over/Under betting outside of Combat Sports

You may have heard of the Over/Under in relation to other sports, where it usually refers to the Total number of points scored in the game. For example, let’s say the Over/Under on an NFL game is offered at 55 points. 

  • If you take the Over, you win if the points total is greater than 55 (say the score is 21-35).
  • If you take the Under, you win if the points total is fewer than 55 (say it ends 21-28).

How it works for MMA

In MMA, the Over/Under is set at the total number of rounds that the fight will last. 

Let’s take for example a 3 x five-minute round fight, set at:

Over 1.5 rounds (-200)
Under 1.5 rounds (+140)

If you believe the fight will finish before the midway point (i.e., halfway through the second round, or at 7:30 on the clock) then you would take the Under, offered at +140. As explained above, the plus sign signifies this is the sportsbook’s underdog position.

Should the fight finish at any time before the halfway mark, a $100 bet on the Under wins $140, returning your $100 stake and winning $40. If the fight goes beyond the halfway mark, the Under loses and the Over wins.

Backing the Over at -200 (the favorite position), requires a $200 stake to win $100.

Example: Khamzat Chimaev vs Li Jingliang Over/Under betting

Let’s use Khamzat Chimaev’s comeback fight against Li Jingliang as an example of how Over/Under betting works in the UFC.

Khamzat Chimaev came into the fight riding a huge hype train, having completely destroyed his first three UFC opponents in very short time.

5 Dimes sportsbook had the market set to Over 1.5 rounds (-130) and Under 1.5 rounds (+110). The implied probability of odds of -130 is 56.52% – meaning 5Dimes expected the fight to end before the midway point of Round 2.

And they were correct. Khamzat Chimaev finished “The Leech” with a Submission at 3:16 of Round 1.

UFC round betting – how to bet on the exact round a fight will finish

If you’re a fan of the UFC heavyweight division, you’ll know that there are more KOs in this division than any other weight class, and you might want to bet on the fight finishing early.

Derrick Lewis

Let’s take the real-world example of the Derrick Lewis vs Curtis Blaydes fight at UFC Fight Night 185 / UFC Vegas 19. If you felt the bout wasn’t going to go to the judges scorecards, you could have bet on the fight ending in any of the scheduled five rounds, at these odds:

Fight ends in round 1 (+250)
Fight ends in round 2 (+400)
Fight ends in round 3 (+550)
Fight ends in round 4 (+800)
Fight ends in round 5 (+1400)

Lewis won that fight by KO/TKO in Round 2 at 01:26 – so you’re either in the money at +400, or… better luck next time. 

UFC Prop bets – aka Specials

For longer odds, you could bet on the winner, the round that the fight ends, and even the method of victory. This is an example of a prop bet. Sometimes they are found listed as specials.

Prop bets – short for proposition bets – are a fun way to turn your predictions into bigger winnings. You can generally find higher odds the more specific your bet is, because of a lower probability of the outcome.

  • Lewis was at +300 to win, but if you picked a Round 2 finish, those odds jumped to +1400. A $100 bet would have made you a $1400 profit.
  • Picking Lewis in Round 2 and by Knockout, would have netted you $1600 on a $100 bet. An extra $200 simply because you looked for a more specific prop bet.

DraftKings and FanDuel offer an extensive range of MMA prop betting markets.

What is Vig?

All sportsbooks charge a fee to place a bet with them, and this is commonly referred to as “vig” – short for “vigorish”. 

It has other names too, like “juice”, or at European-based sportsbooks, often “margin”, but it is the same thing. Think of it as a tax, or the price you have to pay a sportsbook to play.

In the US, the vig will be included in the American odds

To illustrate, let’s say the favorite is at -110 and the underdog as +110. Two bettors each take one side of the action – one backs the favorite, the other the underdog.

On the favorite, you have to risk $110 to win $100. On the underdog, you need to bet $100 to win $110. 

The favorite loses, the bookmaker takes $110 from the bettor who backed the favorite but pays $100 to the bettor who backed the underdog. The bookmaker keeps the $10 vig.

The favorite wins, the bookmaker pays $100 to the bettor who backed the favorite, keeps the $10 vig, while the bettor who backed the underdog loses $100.

Remember, you always have to risk more on a favorite than you’d win on an underdog – it’s how sportsbooks stay in business.

Where to place a UFC bet online in the United States

Placing UFC bets offline in the United States

In Arkansas, Delaware, Maryland, Montana, New Mexico and New York, sports betting is legal, but sports betting online is not yet legal. The legislative process is different from state to state, and at different stages of the process in different states.

If sports betting is legal in your state, but online betting isn’t, your ability to bet on the UFC depends on your proximity to bricks-and-mortar casinos or bookmakers.

For example, New York state residents can bet at casinos upstate, although the action is minuscule compared to New Jersey where online sports betting is legal. Some estimates suggest New Jersey sees $1billion in bets each month – with 20% or so believed to originate from native New Yorkers.

Sports betting in any form, be it online or offline, remains illegal in 27 of the 51 US states.

How Much to Bet: A flat-betting strategy

The concept of flat-betting is a good place to start for sports fans flirting with sports betting.  

If you’re just starting out and interested in giving sports betting a go, a good rule is to risk only what you can afford to lose. You can go big or go home, or, if you’re in it for the long haul, try a flat-betting approach.

This means betting the same amount whenever you bet, while risking only 1%-5% of your bankroll per bet. So, if you’ve given yourself a $1000 to play with, don’t risk more than $50 per event.

By flat-betting, bettors guard themselves against losing their entire bankroll during a bad stretch; and set themselves up for a positive return on investment (ROI) when they’re on a roll.

A brief history of betting in the UFC

Biggest betting upsets in UFC history

Most UFC betting action happens on main card fights, with famous fighters and the hype fuelling MMA bettors. However, you often find best value UFC bets on the prelims. Lesser-known fighters can give Vegas oddsmakers a harder time when trying to set their odds, unwittingly presenting bettors with an opportunity to find value.

Famous UFC betting upsets

Shana Dobson pulled off a huge UFC betting upset when she defeated Mariya Agapova as a +950 betting underdog
Shana Dobson (+950) defeated Mariya Agapova by Knockout at 01:38, Round 2

Shana Dobson was a huge +950 underdog coming into this fight which took place at UFC Vegas 7 in August 2020. She was on a 3-fight losing streak and had yet to get a win in the UFC proper. On the other hand, Mariya Agapova was on a tear and sitting at 8-1-0 in her professional MMA career.

Oddsmakers set the line on Dobson to win at a whopping +950 – meaning if you had placed a $100 bet on her to win, you would have won $950. Not a bad UFC betting profit!


UFC fighter Georges St Pierre famously lost to Matt Serra in a major UFC betting upset
Matt Serra (+850) defeated Georges St Pierre by Knockout at 03:25, Round 1

Matt Serra famously beat GSP at UFC 69, in April 2007. Serra’s win is widely regarded as the most shocking UFC title upset of all time. GSP is undefeated since that defeat, and avenged the loss a year later. In the first fight, not many gave Serra a chance of winning – with oddsmakers pricing him at a +850 underdog.

Serra proved the doubters wrong with a surprise knockout in the first round. Those who did back him were left very happy – a $100 bet on Serra turned into a $850 betting profit.


Holly Holm (+830) defeated Ronda Rousey by Knockout at 0:59, Round 2

Holly Holm shocked the MMA gambling community with a head-kick knockout of the previously invincible Ronda Rousey at UFC 193. Rousey was undefeated and had a 12-0 professional record coming into the fight. She had taken the UFC by storm, finishing all of her opponents by submission or knockout.

Oddsmakers expected Holm to fall victim in a similar fashion, pricing her at a +830 underdog. It was quickly apparent that her boxing skills were far superior, lighting Rousey up on the feet in the first round. She continued with that momentum in round 2, setting up a highlight reel head kick.

A $100 bet on Holly Holm to beat Ronda Rousey would have made a $830 betting profit.

UFC fighter Justin Jaynes famously bet his entire US$25,000 purse on himself (as a +140 underdog) to beat Charles Rosa. 

Can UFC fighters bet?

Yes. As long as they do not risk the integrity of the UFC, they can place bets. That means they can bet on themselves to win, but obviously not to lose, as that would be match-fixing. Justin Jaynes famously bet his entire US$25,000 purse on himself (as a +140 underdog) to beat Charles Rosa

Unfortunately for Jaynes, he lost, meaning he competed in the Octagon that night for free.
