From the main event to the full card, 45kk covers every UFC event and all the top MMA organizations with competitive odds, special markets, and Pix withdrawals in minutes.
MMA has taken Brazil by storm, and UFC in particular dominates everyone's weekends. Watching a fight without having a bet on the line just doesn't feel right anymore — and the 45kk gets it better than anyone. The platform was built for fans who follow the sport for real — the kind of person who knows the difference between jiu-jitsu and wrestling, remembers a fighter's knockout history, and wants to turn that knowledge into actual returns.
At 45kk you get full UFC coverage — from the prelims to the main event — with odds updated in real time as each round unfolds. Beyond the UFC, the platform covers other major organizations including Bellator, ONE Championship, and PFL, so you'll never be short of options on Saturday nights.
Brazil has always been a powerhouse in world MMA. Names like Anderson Silva, José Aldo, Renan Barão, Charles Oliveira, and Alex Poatan have written historic chapters in the UFC, and the new generation continues that legacy with fighters who fill the octagon with technical skill and heart. At 45kk, betting on Brazilian fighters is a celebration of the sport — not just a financial transaction.

Knowing the sport inside out gives you an edge. Here are some practical tips for betting at 45kk.
Brazil has a unique relationship with mixed martial arts. Long before the UFC became the global phenomenon it is today, the country was already producing world champions in jiu-jitsu, Muay Thai, and boxing. When MMA finally hit Brazilian television screens, the sport quickly became part of mainstream culture — and betting on fights became as natural as following a football match.
A 45kk understands that context and built an MMA and UFC section that goes beyond the basics. Here you won't just find the simple result — you get access to dozens of markets per event, live coverage with odds updated round by round, and an interface that works seamlessly on your phone, whether you're at home in front of the TV or following along on the app anywhere you go.
Alex Poatan is the reigning UFC Light Heavyweight Champion and one of the most popular fighters to bet on at 45kk. With an aggressive Muay Thai-based style, his fights rarely go to the judges, which opens up strong opportunities in KO/TKO and exact round markets. Charles Oliveira, the greatest finisher in UFC history, remains a fan favorite in submission markets — even when he enters as an underdog in the pre-fight odds.
Beyond the UFC, 45kk closely follows Bellator, where Patricio Pitbull represents Brazil with top-level quality at featherweight. ONE Championship is also on the radar, with Adriano Moraes being one of the most-followed Brazilian athletes on the platform. That means on weekends, you'll never run out of MMA betting options at 45kk.
Live betting at 45kk during a UFC event is unlike anything else out there. Odds shift within seconds as the round develops — a takedown that swings the judges' scorecards, a flurry of strikes that puts the favorite in trouble — all of it is reflected on the platform instantly. If you watch closely and move fast, you have a real edge.
