We had eagerly anticipated UFC 303 for months, excited for the return of Conor McGregor. However, as we examine the UFC 303 odds and betting lines on our top UFC betting sites, it appears that the event may not be what we had expected.

Conor McGregor seemed set to make his return to the Octagon against English fighter Michael Chandler at UFC 303. Unfortunately, McGregor’s injury prevented him from participating in what would have been his first announced fight.

The main act has changed, but the rest of the lineup seems to be in line with what we have been preparing for.

The Light Heavyweight title will be contested between Alex Pereira and challenger Jiri Prochazka in the headline bout of Pereira-Prochazka 2, replacing McGregor-Chandler as the main event.

We can look forward to an Irish-English showdown between Ian Machado Garry and Michael Page, an exciting match-up between undefeated Payton Talbott and Yanis Ghemmouri, and a Heavyweight clash featuring Andrei Arlovski and Martin Buday.

Below is our analysis of the UFC 303 odds and betting lines for the entire Saturday card to assist you in making your UFC predictions.

UFC 303 odds – Main Card

The latest odds from bet365 were last updated on Friday at 11:15 a.m. ET.

Diego Lopes vs. Brian OrtegaLopes (-138)Ortega (+110)

Mayra Bueno Silva vs. Macy ChiassonBueno Silva (-110)Chiasson (-110)
Ian Machado Garry vs. Michael PageMachado Garry (-160)Page (+130)

Pereira has had his fair share of title fights. The Brazilian competed in the Middleweight division, securing his first title against Israel Adesanya in Nov. 2022, only to lose it in their rematch at UFC 287 in April 2023.

He later transitioned to the Light Heavyweight division, where he defeated Prochazka at UFC 295 in November 2023 to win the vacant title. He successfully defended his championship against Jamahal Hill in April 2024.

Bet365 initially favored him to add another successful defense to his resume, but as the week has gone on, the odds have shifted against him. On Monday, he had -170 odds to win the rematch, but now he is lined at -150. According to our Odds Converter, this implies a 60% chance of winning, which would result in a $6.67 profit on a $10 wager.

UFC 303 odds – Prelims

The odds from Caesars were last updated on Friday at 11:20 p.m. ET.

FightFavoriteUnderdog
Joe Pyfer vs. Marc-Andre BarriaultPyfer (-300)Barriault (+240)
Andre Fili vs. Cub SwansonFili (-235)Swanson (+195)
Charles Jourdain vs. Jean SilvaJourdain (-115)Silva (-105)
Payton Talbott vs. Yanis GhemmouriTalbott (-1600)Ghemmouri (+800)

Talbott, with an undefeated professional MMA record, is the clear favorite in the betting odds for UFC 303 as he prepares to face Ghemmouri. Talbott has achieved two KO/TKO victories in FirePower Promotions MMA and three more in Urijah Faber’s A1 Combat.

The only time the judges played a role in his career was during a unanimous-decision win over Reyes Cortez Jr. at DWCS: Season 7, Week 1. His two UFC bouts have both ended in stoppages, with a submission victory over Nick Aguirre in November 2023 and a return to his KO/TKO victories against Cameron Saaiman in March 2024.

With -1600 odds at Caesars, he has a 94.12% chance of winning, but would only make a profit of 63 cents on a $10 bet.

How to read UFC betting odds

To place informed wagers, it is crucial to comprehend UFC betting odds. Let’s analyze this with some 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 analyze a real UFC betting scenario:

  • Fighter A: +200
  • Fighter B: -180

If you bet $100 on Fighter A (+200), you would win $200 in profit for a total payout of $300. For Fighter B (-180), you would need to bet $180 to win $100 in profit, resulting in a total payout of $280.

By grasping these odds, you can assess the potential payout and implied likelihood of victory for each fighter in a UFC match. Positive odds suggest an underdog status, whereas negative odds indicate a favorite.
