UFC 331 main card odds

Joshua Van vs Alexandre Pantoja odds

Fighter Kalshi
Probability
Joshua Van 54%
Alexandre Pantoja 46%

This is a much-anticipated rematch after Pantoja suffered an injury during their first battle at UFC 323.

Van claimed the flyweight title nine months back when Pantoja succumbed to an elbow injury 23 seconds into the fight. Now Van is out to prove he's the legitimate champion, while Pantoja seeks to become the third fighter to hold the flyweight title twice.

Arman Tsarukyan vs Mauricio Ruffy odds

Fighter Kalshi
Probability
Arman Tsarukyan 73%
Mauricio Ruffy 27%

This is a rare five-round faceoff that isn't for a title, though it's widely thought that whoever rises up will get their shot next in the lightweight division.

Arman Tsarukyan has taken some time off since last November, when he recorded his fifth straight win while defeating Dan Hooker, improving to 10-2. Mauricio Ruffy's takedown defense will need to be stout, but he's recently tallied impressive wins over Michael Chandler and Rafael Fiziev.

Patricio Pitbull vs Dooho Choi odds

Fighter Kalshi
Probability
Patricio Pitbull 31%
Dooho Choi 69%

Dooho Choi is riding high after three straight knockout wins. He packs plenty of power and has registered 14 knockout victories throughout a lengthy career. But Patricio Pitbull boasts a similar approach and repertoire, meaning there could be plenty of fireworks in this one.
