It's not the UFC 303 that we had spent months hyped about due to a change in headliner, but fight fans still have an awesome slate of fights on their hands, and we have you covered with the UFC 303 odds and betting lines from our best UFC betting sites.
Three weeks ago we thought we were going to get the return of Conor McGregor at UFC 303, but that quickly changed when the former champ pulled out of his return fight with Michael Chandler due to injury.
But Dana White and Co. still have a banger of a headliner for us at UFC 303, as the Light Heavyweight strap will be on the line between Alex Pereira and the challenger, Jiri Prochazka, at Pereira-Prochazka 2.
We also still get treated to a number of fights we were going to get originally, including Ian Machado Garry battling Michael Page, the undefeated Payton Talbott risking his unblemished reco rd against Yanis Ghemmouri, and a Heavyweight throwdown between Andrei Arlovski and Martin Buday.
Here's our breakdown of the UFC 303 odds and betting lines for Saturday's full card to help with your UFC picks.
UFC 303 odds – Main Card
Odds via bet365 last updated Monday at 11 a.m. ET.
| Fight | Favorite | Underdog |
|---|---|---|
| Alex Pereira vs. Jiri Prochazka | Pereira (-170) | Prochazka (+140) |
| Diego Lopes vs. Brian Ortega | Lopes (-150) | Ortega (+125) |
| Roman Dolidze vs. Anthony Smith | Dolidze (-150) | Smith (+125) |
| Mayra Bueno Silva vs. Macy Chiasson | Bueno Silva (-138) | Chiasson (+110) |
| Ian Machado Garry vs. Michael Page | Machado Garry (-138) | Page (+110) |
Pereira is no stranger to title fights. The Brazilian once battled in the Middleweight division, winning his first title from Israel Adesanya in Nov. 2022, which he promptly lost in their rematch at UFC 287 in April 2023.
He then switched to Light Heavyweight, and at UFC 295 in Nov. 2023, he topped Prochazka in their first meeting to claim the vacated title. In April 2024, he successfully defended the strap against Jamahal Hill.
bet365 has him lined as though he'll add another successful defense to his resume, getting -170 odds to win the rematch. Our Odds Converter tells us that's a 62.96% implied win percentage, profiting $5.88 on a $10 wager.

UFC 303 odds – Prelims
Odds via Caesars last updated Monday at 11:05 a.m. ET.
| Fight | Favorite | Underdog |
|---|---|---|
| Joe Pyfer vs. Marc-Andre Barriault | Pyfer (-260) | Barriault (+210) |
| Andre Fili vs. Cub Swanson | Fili (-230) | Swanson (+190) |
| Charles Jourdain vs. Jean Silva | Jourdain (-125) | Silva (+105) |
| Payton Talbott vs. Yanis Ghemmouri | Talbott (-1600) | Ghemmouri (+800) |
There's no bigger betting favorite at UFC 303 than Talbott, who is putting his undefeated professional MMA record on the line against Ghemmouri. Talbott picked up two KO/TKO victories in FirePower Promotions MMA before moving to Urijah Faber's A1 Combat, where he notched three more KO/TKO wins.
The lone time the judges were involved in his career was a unanimous-decision victory over Reyes Cortez Jr. at DWCS: Season 7, Week 1. His two UFC fights have also ended in stoppages, as he submitted Nick Aguirre in in Nov. 2023 and got back to his KO/TKO ways against Cameron Saaiman in March 2024.
His -1600 odds imply a 94.12% win percentage, but profit just 63 cents on a $10 wager over at Caesars.

UFC 303 odds – Early prelims
Odds via BetMGM last updated Monday at 11:10 a.m. ET.
| Fight | Favorite | Underdog |
|---|---|---|
| Gillian Robertson vs. Michelle Waterson-Gomez | Robertston (-175) | Waterson-Gomez (+145) |
| Martin Buday vs. Andrei Arlovski | Buday (-278) | Arlovski (+225) |
| Rei Tsuruya vs. Carlos Hernandez | Tsuruya (-455) | Hernandez (+340) |
| Ricky Simon vs. Vinicius Oliveira | Simon (-227) | Oliveira (+185) |
The card's lone Heavyweight battle occurs in the early prelims with Buday and Arlovski. At 45 years old, Alovski enters on a skid, dropping three straight since the last time he had his arm raised in April 2022. BetMGM isn't expecting that skid to end, listing the American at +225 against the much younger Buday.
That's just a 30.77% implied win percentage, but profits $22.50 on a $10 wager.

How to read UFC betting odds
Understanding UFC betting odds is essential for making informed wagers. Let's break it down with examples:
- Positive odds (+): Positive odds indicate the potential profit on a $100 wager. For instance, if a fighter has odds of +250, it means that a $100 bet on that fighter would yield a profit of $250 if they win the fight. So, your total payout would be $350 ($250 profit + $100 original stake).
- Negative odds (-): Negative odds represent the amount you need to wager to win $100 in profit. For example, if a fighter has odds of -150, it means that you would need to bet $150 to win $100 in profit if that fighter wins. Your total payout would be $250 ($100 profit + $150 original stake).
Now, let's consider an actual UFC betting scenario:
- Fighter A: +200
- Fighter B: -180
For Fighter A (+200), a $100 bet would result in a $200 profit, making the total payout $300. For Fighter B (-180), you would need to wager $180 to win $100 in profit, resulting in a total payout of $280.
Understanding these odds helps you evaluate the potential payout and implied probability of each fighter winning a UFC fight. Positive odds indicate an underdog, while negative odds signify a favorite.
