Best prediction market apps & bonuses for Dana White’s Contender Series Week 4

As Week four approaches, Dana White’s Contender Series: Season 10 has lived up to its name with the biggest upset yet in DWCS history. Week 3 saw Bella Mir, daughter of former UFC heavyweight champion Frank Mir, take a pummeling from Alex Apodaca—she came in as the underdog, but won by unanimous decision. It goes to show how quickly the tables can turn, even against legacy favorites. So, with Alex Apodaca having snagged a UFC contract, what are the storylines to watch for in Week 4? Well, the best prediction market sites, like Kalshi and Polymarket, are already fielding their favorites by crowd sentiment.

Top of the list is the Patrick Rivera v Adam Darby main card bout: a welterweight match between Rivera, on a six-fight win streak, and Darby, monikered “The Plank,” who’s 3 inches taller than Rivera and seven years younger. Going by prediction market news, Adam Darby is the overwhelming favorite to win, with critics and fans alike booking this matchup as a genuine UFC doorway. Other must-watch fights include Lourenço v Cleveland (in the heavyweight bracket) and others in the middleweight and lightweight divisions.
