The UFC has put together quite the card for UFC Freedom 250, with the two title bouts headlining a deep and loaded seven-fight card. 

The main event between Topuria and Gaethje is the first fight between these two historic lightweight fighters. Topuria is the champ, but he hasn't fought since June of 2025. Gaethje last fought in January, beating Paddy Pimblett for the interim title. Topuria is undefeated and is viewed as likely to win this matchup, as him winning is currently 81 cents per share at Kalshi. 

The heavyweight tilt between Gane and Pereira is for the interim heavyweight title, and traders appear very split on who will win this clash. A Gane win is 49 cents per share while a Pereira victory is 52 cents per share. Pereira is 13-3 and has won six of his last seven fights, including winning the light heavyweight title last year, which he'd later vacate. Gane is 13-2-1, and his last fight was a no contest after an eye poke to Tom Aspinall last October in a fight for the heavyweight championship.

Sean O'Malley has dropped two of his last three fights heading into a bantamweight tilt with Aiemann Zahabi, who has won seven straight bouts. O'Malley is seen as the more likely victor, though, at 77 cents per share to Zahabi's 23 cents per share price. Zahabi notably hasn't lost since 2019.

Another heavyweight clash takes place on this card with Josh Hokit facing Derrick Lewis. Lewis is always a fun fighter to watch as he's a knockout specialist, securing 24 of his 29 wins that way. Hokit is a young up-and-comer who is 9-0 to begin his career, and he owns five KO wins of his own. This one should be fast-paced and hard-hitting. Hokit is 77 cents per share to win while Lewis is 24 cents a share to emerge victorious. 

Another veteran vs. youngster fight on the card is a lightweight bout between the 40-year-old Michael Chandler and the 29-year-old Mauricio Ruffy. Chandler has lost five of his last six fights entering Sunday, while Ruffy is 13-2 overall in his career, though he lost two fights ago to Benoît Saint Denis in September 2025. This could very well be a breakout night for Ruffy, who is 85 cents a share to beat Chandler, who is just 17 cents a share to win.

Bo Nickal, another fighter without a ton of experience, looks to make his presence felt on a big stage in a middleweight bout against Kyle Daukaus. Nickal is 8-1 to begin his MMA career and last beat Rodolfo Vieira by KO in November. Daukaus is 17-4-1 and is on a six-fight win streak. Nickal is expected to emerge victorious here against the more experienced fighter as he's 77 cents a share to win while Daukaus is 25 cents a share to pick up his seventh win in a row.

Two of the top-10 featherweights will clash on Sunday with Diego Lopes (No. 2) taking on Steve Garcia (No. 9). Lopes, who is 27-8, has won six of his last eight fights, with both losses coming to current featherweight champ Alexander Volkanovski. Garcia is 19-5 in his career and has won seven straight fights. Fifteen of his 19 career wins are via KO. Lopes is 61 cents a share to win while Garcia is 41 cents a share. Trade on UFC Freedom 250 and more at Kalshi with the promo code SPORTSLINE10:
