UFC Vegas 107 takes place Saturday, May 31st at the UFC Apex
Erin Blanchfield faces Maycee Barber with significant line movement
Check out the latest UFC Vegas 107 odds shifts and our updated predictions
With UFC Vegas 107 just hours away, the betting lines have seen some notable movement since opening earlier this week. Erin Blanchfield and Maycee Barber clash in the main event, with Barber’s half-pound weight miss on Friday adding another wrinkle to an already intriguing matchup.
The co-main event between lightweights Mateusz Gamrot and Ludovit Klein has held relatively steady, while other fights on the main card have seen dramatic shifts. Let’s break down the updated odds and what the movement means for our final predictions.
Updated UFC Vegas 107 Odds
| Fighter | Moneyline Odds | Over/Under Rounds |
|---|---|---|
| Erin Blanchfield | -258 (was -238) | O4.5 -188 |
| Maycee Barber | +210 (was +195) | U4.5 +145 |
| Fighter | Moneyline Odds | Over/Under Rounds |
| Mateusz Gamrot | -148 (was -155) | O2.5 -298 |
| Ludovit Klein | +124 (was +130) | U2.5 +220 |
| Fighter | Moneyline Odds | Over/Under |
| Billy Ray Goff | -440 (was -340) | O1.5 -166 |
| Ramiz Brahimaj | +340 (was +270) | U1.5 +130 |
| Fighter | Moneyline Odds | Over/Under Rounds |
| Dustin Jacoby | -198 (was -185) | O2.5 -115 |
| Bruno Lopes | +164 (was +154) | U2.5 -115 |
| Fighter | Moneyline Odds | Over/Under Rounds |
| Macy Chiasson | -148 (was +100) | O2.5 -375 |
| Ketlen Vieira | +124 (was -120) | U2.5 +270 |
| Fighter | Moneyline Odds | Over/Under Rounds |
| Zachary Reese | -218 (was -245) | O1.5 +140 |
| Dusko Todorovic | +180 (was +200) | U1.5 -180 |
The most dramatic shift comes in the welterweight bout where Billy Ray Goff has seen his odds balloon from -340 to -440, pushing Ramiz Brahimaj out to +340.
Meanwhile, the women’s featherweight matchup between Macy Chiasson and Ketlen Vieira completely flipped after Vieira’s weight cut issues forced the bout to a 145-pound catchweight.
Blanchfield’s line has strengthened despite – or perhaps because of – Barber’s weight miss, with “Cold Blooded” now sitting at -258, giving her 72.1% implied probability to win.

Final UFC Vegas 107 Predictions
With the lines settled and fight night upon us, here are my top plays for the UFC Vegas 107 main card.
Best Bet: Macy Chiasson Wins by KO/TKO/DQ (+650 at DraftKings)
The odds flip in the Chiasson-Vieira bout tells the whole story. Vieira’s struggles to make 135 pounds forced this to a featherweight contest, and that’s terrible news for the Brazilian. Chiasson already held significant height and reach advantages – now she’ll have an even bigger size edge on fight night.
She is SHARP everywhere 😮💨

— UFC (@ufc) May 28, 2025
Chiasson has finished her last two fights via strikes, showing improved killer instinct. Her nasty elbows from top position have been particularly effective. With Vieira likely depleted from the failed cut, I see Chiasson overwhelming her with size and physicality before finding a stoppage. The +650 price on a TKO offers tremendous value.
Value Play: Ludovit Klein (+124 at DraftKings)
While most are backing Gamrot’s wrestling, Klein presents unique challenges. His 91% takedown defense rate leads all active UFC lightweights, and his striking is sharp and technical. The minimal line movement suggests smart money sees this as closer than the odds indicate.
Three things that make Ludovit Klein great at defending takedowns (91%)
1) Cuts angles with his hips (leverage)
2) Excellent balance (on feet & hands)
3) Forces the head away from him
Bonus: He digs great underhooks as well, just not in this clip 👍🏼 pic.twitter.com/d8FHZvSd4Y

Gamrot has been dropped or hurt in several recent fights, including his loss to Dan Hooker. If Klein can stuff enough takedowns and keep this standing, his cleaner boxing and devastating leg kicks could steal rounds. In a three-round fight at the Apex, where judges often undervalue control time, Klein at plus money is worth a shot.
Other UFC Vegas 107 Main Card Predictions & Best Bets:
Erin Blanchfield (-258) grinds out Barber with wrestling; skip the inflated moneyline, bet Blanchfield by decision (+100)
Billy Ray Goff (-440) line too wide now; consider fight goes distance (+165) as Brahimaj is durable
Zachary Reese vs Dusko Todorovic under 1.5 rounds (-180) in a guaranteed slugfest
The main event line movement reinforces that Blanchfield should control this fight, but Barber’s toughness means a finish is unlikely. With Barber never going five rounds before and coming off a year layoff, Blanchfield’s experience and cardio should be the difference in the championship rounds.
For Goff-Brahimaj, that massive line shift has me second-guessing the stoppage. When odds move that dramatically, the value often lies in fading the public perception. Brahimaj has never been finished in the UFC and could make this uglier than expected.
The Reese-Todorovic opener screams violence. Both men have suspect chins and heavy hands – someone’s getting slept early. The under 1.5 rounds at -180 remains playable despite the juice.
