From football to MMA, basketball to e-sports — 399w brings together the top sports from Brazil and around the world on a fast, secure platform with Pix withdrawals in minutes.
Football, MMA, basketball, volleyball, tennis, e-sports, and much more — all on a single platform.
Odds updated in real time. Bet before kick-off or during the event at 399w.
Anyone who has tried betting on foreign platforms knows the frustrations: interfaces in another language, complicated payment methods, support that takes days to respond, and when you do win, a withdrawal process so bureaucratic it can drag on for weeks. The 399w was built to be the opposite of that — designed from the ground up for the Brazilian bettor, fully in Portuguese, with Pix for deposits and withdrawals, and support that actually responds.
The sports portfolio at 399w goes well beyond football. There are 30+ sports covered, from the Brasileirão to the NBB, from the UFC to CS2, including tennis, volleyball, Formula 1, NBA basketball, and even snooker. For each sport, the platform offers deep markets — not just the match winner, but dozens of more specific options that let knowledgeable bettors find real value where others don't.
In football, the 399w covers the Brasileirão Série A and Série B round by round, the Copa do Brasil from the early stages, the full Libertadores and Sul-Americana, plus the biggest state championships like Paulistão, Carioca, and Gaúcho. But the coverage goes well beyond Brazil: the English Premier League, La Liga, Champions League, Bundesliga, and Italian Serie A are all available with dozens of markets each. Bettors who like to mix it up across leagues have plenty of room to explore.
MMA and UFC betting is growing fast at 399w. Brazil has a special relationship with MMA — we are one of the countries with the most athletes in the UFC, and Brazilian fans follow every fight with incredible intensity. The platform covers all UFC cards with markets such as winner by decision, knockout, submission, specific round, and much more. When a Brazilian fighter is on the card, the MMA section at 399w becomes the stage for serious action.
Basketball has been growing fast among Brazilian bettors, and 399w followed suit. The NBB — Nacional Basketball Brasil — has full coverage, and the NBA is one of the markets with the most betting options per game on the platform. Point handicap, total points, quarter-by-quarter scoring, three-point attempts, and individual player performance are just some of the markets that make the difference for bettors who truly study the American game.
E-sports also has its dedicated space on 399w. CS2, League of Legends, Dota 2, Valorant, and other competitive titles are covered with competitive odds. For those who follow the Brazilian competitive scene — especially FURIA, one of the country's most prominent teams on the international CS stage — betting at 399w during a major tournament is an experience like no other. Odds move fast, and the live market in this segment is especially dynamic.
Live betting is one of the most valued features among users of 399w. Odds are updated in real time across all covered events — not just football, but basketball, tennis, volleyball, and e-sports too. Watching an NBA game live and spotting that the odds on the team you think will turn it around are looking great is exactly the kind of opportunity that 399w's live betting delivers. Cashout is also available on live bets, letting you settle part of your return before the final result.
Accumulators are one of the most popular bet types among 399w. When you combine two or more events into a single bet, the odds multiply and your potential return grows significantly. To reward this type of bet, the platform offers a scaling bonus on accumulator returns: 5% for 3 selections, 8% for 4, and up to 10% for accumulators with 5 or more events. It's a straightforward way to reward bettors who put real effort into building a well-structured accumulator.
