Over 80 betting markets per fight — from straightforward picks to in-depth props
The most popular market at 631bet for MMA betting. Pick the fighter you think will win. Simple, straightforward, and with competitive odds on the biggest UFC events.
Bet not just on who wins, but how they win: KO/TKO, submission, unanimous decision, split decision, majority decision, or technical draw. Higher odds, sharper analysis.
Pick the exact round the fight will end in. One of the best-value markets for those who study each fighter's style — rounds 1 and 2 tend to offer particularly attractive odds.
Bet on whether the fight ends before or after X:30 of a given round. For example: "ends before 2:30 of round 2". A great option for fights featuring high-finishing fighters.
During the event, 631bet updates odds in real time between rounds and throughout the action. You can place bets based on exactly what's happening inside the octagon — a huge edge for anyone watching the event live.
Build parlays with winners from multiple fights on the same card. Odds multiply with each selection — a 4-fight parlay can turn R$ 20.00 into hundreds of BRL if every pick lands.
Bet with a round handicap in favor of or against a fighter to level the playing field when there's a clear favorite. For example: betting on the favorite with a -1.5 round handicap means they must win before round 2.
For title fights, 631bet offers long-term outright markets: who will be the next champion in each weight class? Odds go live weeks before the event, with excellent potential returns.
Bet on which fighter will receive the "Fight of the Night" or "Performance of the Night" bonus at the end of the event. A niche market with very attractive odds for those who know the athletes' styles well.
In under 5 minutes you're already betting on the next fight. Here's how:
Sign up in under 2 minutes — all you need is your CPF, email, and phone number. You'll have full access to the MMA and UFC section from the start.
Pix, bank slip, credit card, PicPay, or Mercado Pago. Pix deposits land in under 30 seconds and you can start betting right away.
In the sports menu, click on "MMA / UFC". All available events are listed by date, with each fight's markets displayed directly below.
Click the odds you want to add them to your bet slip. Enter your stake and confirm. You can combine multiple bouts into a single parlay bet.
During the event, follow the action with live betting and real-time odds. If you win, request your withdrawal — Pix deposits arrive in up to 15 minutes.
MMA odds at 631bet use the decimal (European) format. An odd of 2.00 means that for every R$ 1.00 wagered you get R$ 2.00 back (stake included) — a profit of R$ 1.00. An odd of 1.50 returns R$ 1.50 for every R$ 1.00 staked. In MMA, odds above 3.00 are common for underdogs, while clear favorites typically range between 1.30 and 1.65.
Tip: method of victory bets multiply the odds. Betting on a fighter to win by submission rather than just to win can double or triple the odds — making it a far more rewarding market for those who do technical fight analysis.
If a fight is cancelled or postponed before it starts, 631bet refunds 100% of the wagered amount directly to your account balance — no need to contact support. In cases of withdrawal (medical TKO, no contest), standard market rules apply — bets are generally refunded if the fight ends before the minimum round established in the market conditions.
For withdrawals, the amount is credited to your account within up to 30 minutes after the cancellation is confirmed by the event organizer.

UFC, Bellator, PFL, ONE Championship, and Brazilian MMA events — all covered by 631bet. You don't need more than one platform to bet on every fight you follow.
MMA has grown tremendously in Brazil over the past few years, and it's not hard to see why: the country has a deep-rooted tradition in martial arts — from jiu-jitsu and muay thai to boxing — and a roster of world-class fighters competing at the highest levels globally. Alexandre Pantoja as UFC champion, Renato Moicano making waves at lightweight, Caio Borralho climbing the middleweight rankings — Brazil is well represented in the octagon, and the 631bet is here to make every event even more thrilling.
Among all the sports available at 631bet, MMA has one defining characteristic: any fight can end at any moment. A fighter who's dominating can be submitted in a lapse of concentration. The heavy favorite can be flattened by a first-round knockout out of nowhere. That unpredictability is what makes MMA betting so exciting — and so profitable for those who analyze matchups carefully.
Method of victory markets are the top choice among the most experienced bettors at 631bet. While betting on the winner of a fight between two evenly matched fighters might return odds of 1.80, betting on a win by a specific finish method can easily reach 3.50 or 4.00 — nearly double the return. For those who study fighting styles, that's a genuine edge.
The UFC is, without question, the world's premier MMA organization and the event that drives the most betting activity at 631bet. Major cards like UFC 300, UFC Fight Night, and so-called "PPV events" feature dozens of bouts on the full card — from the prelims to the main event — and the 631bet covers all of them with a wide range of markets.
Alexandre Pantoja, the Brazilian flyweight champion, is one of the fighters who draws the most betting activity on the platform. In events where he competes, betting volume at 631bet rises significantly — national pride fuels the interest, and those who back the champion at good odds are well rewarded when he does what he does best: finish by jiu-jitsu submission or win by dominant decision.
Beyond the UFC, the 631bet covers Bellator, PFL, and ONE Championship with the same depth of markets. Brazilian fighters like Natan Schulte in the PFL and Douglas Lima in Bellator have dedicated fan bases that follow every fight closely and love to bet on their representatives.
One of the features that 631bet 631bet users value most is the live betting platform during MMA events. Unlike football, where the score shifts gradually over 90 minutes, MMA can swing completely in a matter of seconds — creating unique opportunities for quick-thinking bettors.
Picture a fighter having a rough first round — taking damage and looking in serious trouble. His odds to win will spike. If you know his track record — that he tends to get stronger in rounds two and three, has excellent cardio, and a history of comebacks — that could be the perfect moment to place a live bet at returns far higher than what was available before the fight.
The 631bet updates odds between rounds and, in select markets, during live action. Partial cash out is also available — if your bet is winning in round two but you're unsettled about round three, you can lock in part of your profit right away while keeping a smaller stake on the final outcome.
Yes, very much so. The BRL 200.00 bonus for bettors who correctly pick the UFC main event winner is one of the most straightforward and transparent offers in the Brazilian market. The condition is simple: deposit BRL 100.00 or more, bet on the main event at minimum odds of 1.70, call the winner correctly, and the BRL 200.00 bonus is credited automatically. The rollover is just 1x the bonus amount — meaning you only need to wager BRL 200.00 once more to convert it into real funds.
Compared to bonuses with 10x, 15x, or 20x rollover requirements, 631bet's 1x rollover is practically instant. Any subsequent sports bet counts toward the requirement — whether on the same UFC card, the following week's Brasileirão, or any other available market.
Many bettors stick to the UFC because it's the most well-known organization, but that means leaving money on the table. The PFL (Professional Fighters League) runs a season-based format with playoffs that creates unique markets — you can bet on who will reach the season finals, opening up long-term wagers with very attractive odds.
ONE Championship, Asia-based but with a global reach, features high-caliber fighters and, because it gets less coverage in the Brazilian sports media, its odds are often mispriced — an edge for bettors who follow the organization closely. The 631bet covers all major ONE Championship events with the same detailed markets available for the UFC.
For those just getting started with MMA betting at 631bet, a few practical guidelines can make a real difference. First: analyze each fighter's style before betting on method of victory. A high-level jiu-jitsu grappler is far more likely to win by submission than by KO. A Muay Thai striker has a better chance of a knockout in the early rounds.
Second: venue matters. Home fighters — especially in Brazil when the UFC or Bellator comes to the country — tend to perform at a higher level; the crowd energy makes a real difference. The 631bet has seen this play out time and again at events held in São Paulo and Rio de Janeiro, where the crowd's support for certain Brazilian fighters was unmistakable.
Third: use MMA parlays in moderation. Combining three or four winners from different fights can be tempting given the multiplied odds, but MMA is especially unpredictable — a single upset brings down the entire parlay. A safer approach is to combine winner and method of victory within a single fight you've studied thoroughly, rather than parlaying multiple fights you know less about.
Fourth: take advantage of the live betting that 631bet offers. Especially in five-round fights (title bouts), there's far more time for odds to move and create opportunities. Follow the event on your phone with 631bet open and be ready to act between rounds when the odds are in your favor.
