377bt goes far beyond a simple "who will win." Each UFC fight has over 20 available betting markets — from the main result to specific details of every matchup.
The simplest market: who wins the fight? Available pre-fight and live throughout each round, with odds updated in real time.
KO/TKO, submission, or judges' decision? Each method carries its own odds and pairs perfectly with a technical read on the fighters.
Which round will the fight end in? Bet on a specific round (1, 2, 3, 4, or 5) with higher odds available for later rounds — big returns for those who get it right.
Will the fight go past X rounds or end early? Over/Under 2.5 rounds is one of the most popular MMA markets — and it lines up perfectly with style analysis and fighter track records.
A straightforward binary bet: will the fight go to the judges' scorecards (Yes) or be stopped before the full 3 or 5 rounds are completed (No)? A great pick for matchups between finishers or knockout artists.
Combine the winner with the method of victory in a single bet. Much higher returns — for example, "Fighter A by submission" multiplies the odds of the two separate bets.

MMA has become a national passion in Brazil, and it's easy to see why. The country has produced some of the greatest fighters in UFC history, and every card featuring Brazilian athletes drives excitement across the board. At 377bt, that passion for the sport translates into full betting coverage: exclusive markets, competitive odds, and the ability to follow every round live while your bets are still open.
If you've never bet on MMA before, the good news is that the sport is easier to analyze than it looks. Unlike football, where 22 players are constantly interacting across a large field, in MMA it's two fighters with well-defined styles inside an octagon. Understanding each athlete's record, fighting style (striker, grappler, wrestler), and physical condition is already enough to bet more informed than a shot in the dark.
Anderson Silva, Lyoto Machida, José Aldo, Vitor Belfort, Wanderlei Silva, Minotauro — Brazil wrote a huge chapter of UFC history. That legacy lives on: fighters like Charles "Do Bronx" Oliveira, Alex Pereira, Jiri Prochazka, and others continue to represent with pride. For Brazilian bettors, following their compatriots adds a whole different level of excitement — and 377bt gets that.
When there's a UFC event in Brazil or a card featuring prominent Brazilian fighters, the 377bt regularly runs special promotions: boosted odds on the main event, free bets for new users, and additional cashback for VIP members. These offers appear in the Promotions section ahead of time — worth checking in the days leading up to each major card.
Betting on MMA goes far beyond cheering for your favorite fighter. Several factors make all the difference when analyzing a fight: each athlete's fighting style, their win/loss record (and especially the method — how many by KO, submission, or decision), current physical condition, recent injuries, and how each fighter performs against different styles.
For instance, an elite striker may struggle against a high-level wrestler. A ground-and-pound specialist can be submitted by an advanced jiu-jitsu fighter. This rock-paper-scissors dynamic of styles creates value opportunities in the odds — especially in the method of victory market, where 377bt offers attractive odds on submissions and knockouts.
Weight is another key factor. Fighters moving up or down a division often perform unpredictably in their first fights at the new weight class. 377bt provides historical performance stats for each fighter directly on the platform — a useful tool for anyone looking to go beyond a gut feeling.
Live MMA betting is unlike any other sport. In football, a goal changes the score but the game keeps going for a long time. In MMA, a single strike can end everything in seconds — and that's exactly why live odds shift so fast. A fighter who was winning the first two rounds could be getting battered against the cage in the third, and the odds reflect that instantly.
At 377bt, live MMA betting is open during the rounds — not just between them. That means you can watch the start of a round, notice that one fighter looks more tired or is controlling the distance better, and place a bet while that information still isn't fully priced into the odds. It's an edge for those who are paying close attention and know each fighter's style.
Live cash out is also extremely valuable in MMA. Imagine you bet on a submission in R3. Your fighter dominated the first two rounds and looks on track to win by decision, but in R3 secures a promising clinch. 377bt offers a cash out value you can accept — locking in your profit — or keep the bet open and hope for the submission. That flexibility is one of the platform's biggest strengths.
A popular strategy among experienced MMA bettors at 377bt is building parlays within the same card. For example, on a UFC Fight Night with 12 bouts, you can combine five or six picks on a single slip — the potential return is much higher than with single bets, and if you know the fighters well, the risk can be managed.
A common strategy is to combine clear favorites (low odds) with one or two higher-risk picks (longer odds), aiming for an attractive multiplier without completely sacrificing consistency. With R$ 20.00 on a five-leg parlay of favorites at average odds of 1.55 each, the potential return exceeds R$ 180.00 — far more than five separate single bets would return.
Beyond the UFC, the 377bt covers Bellator MMA and ONE Championship — two of the biggest MMA organizations outside the UFC. Bellator has a rich history of matchups between former UFC champions and its own divisional stars, with high-quality cards especially at middleweight and heavyweight. ONE Championship, in turn, blends MMA with Muay Thai, kickboxing, and jiu-jitsu in a competition format, creating a very different range of markets from classic UFC.
For fans who follow boxing closely, 377bt also covers high-profile boxing bouts when there is strong interest from the Brazilian audience. Saúl "Canelo" Álvarez, Tyson Fury, Anthony Joshua, and other global names appear on the platform regularly whenever their cards reach worldwide relevance.
