Round-by-round markets, method of victory, fight duration, and more. From the octagon to your phone in real time, with Pix withdrawals in under 10 minutes.
Brazil is one of MMA's greatest powerhouses. From the era of Wanderlei Silva and Anderson Silva to today's generation of Alexandre Pantoja, Charles Oliveira, Amanda Nunes, and Caio Borralho, the country has never stopped producing champions. That's why ii33 created a section entirely dedicated to MMA and UFC, with the level of detail Brazilian fans deserve.
When you open the MMA section on ii33, you won't just find a simple moneyline bet. You get access to dozens of markets for each fight: round-by-round results, method of victory (KO, TKO, submission, unanimous decision, split decision), whether the fight goes to the judges or ends early, over/under rounds, and even special markets like "will there be a knockdown?" or "will either fighter be taken down?". That depth of markets is what sets ii33 apart from other platforms.
For UFC cards in particular, ii33 offers live odds that update between rounds — so if you saw a fighter dominate Round 1 but their odds haven't caught up yet, that could be a real value opportunity. All of it accessible on mobile, no lag, with a Portuguese-language interface and 24/7 support.
By round, method, duration, and much more for every fight.
Updated between rounds based on how the fight unfolds.
Cash out before the final bell and lock in part of your winnings.
Less than 10 minutes to receive your winnings in your bank account.
Bet on the winner, the method, and dozens of other markets before or during the fight.
It goes way beyond "who wins". Explore every possible outcome of each matchup.
Betting on MMA requires a different eye than football. There are no draws, the fight can end at any second, and one misjudged analysis can flip your bet upside down in milliseconds. That's why ii33 was built to give bettors as much information as possible — before and during every fight.
Before betting on any fight at ii33, start by analyzing each fighter's style. A grappling specialist will look to take the fight to the ground and hunt for submissions — so if you think he wins, betting on "victory by submission" can offer much better value than a straight "fight winner" bet. A boxer or Muay Thai striker, on the other hand, will want to keep it standing, where KO/TKO finishes are far more likely.
For Brazilian fans who follow the UFC closely, ii33 offers special coverage of homegrown fighters. When Alexandre Pantoja defends the flyweight title, the platform unlocks extra markets like "Which round does Pantoja finish?" or "Does Pantoja take his opponent down?" That level of detail exists because ii33 knows Brazilian fans don't just want to cheer — they want to cheer and make money at the same time.
Another popular strategy among ii33 users is betting on over/under rounds markets. If two finishers with a history of ending fights early are matched up, the "under 1.5 rounds" market can offer an attractive price. Conversely, if both fighters are durable and tend to go to the judges, "over 2.5 rounds" can be a solid value bet. ii33 offers these markets at competitive odds for every fight on the card — not just the main event.
During live fights at ii33, odds update between each round. This creates unique opportunities: if an underdog clearly dominated the first round, the odds after the break may not yet fully reflect what happened inside the octagon. Experienced bettors use these moments to find value. Cash out is also available on live MMA events — if your bet is winning and the fight is still going, you can lock in part of your profit before it ends.
To deposit and bet at ii33, you can use Pix, boleto bancário, credit or debit card, PicPay, or Mercado Pago — all in BRL, with no currency conversion fees. The minimum deposit is R$ 20.00, enough to place several bets across a UFC card. And when you win, Pix withdrawals hit your account in under 10 minutes, any day of the week.
Beyond the UFC, ii33 covers other top-tier MMA events including Bellator, ONE Championship, and PFL. These events often carry odds with better value than UFC markets — especially when lesser-known fighters with strong records are involved. If you follow the international MMA circuit closely, ii33 rewards that knowledge with detailed markets and fair odds.

"I bet on Pantoja to submit in round 3 at odds of R$ 4.20 on ii33. That's exactly what happened. I withdrew R$ 2,100.00 via Pix right after the event. I've never found a platform with this many UFC markets."
"I've been an MMA fan for years, and ii33 is the only place I can find a 'split decision' market for lightweight bouts. That's where the real value is. I've made good money betting on it here."
"I used Cash Out during UFC Fight Night when my fighter was winning but got rocked in round 3. I walked away with R$ 620.00 locked in. Without that feature, I would have lost everything. ii33 saved me on that one."
