FighterDraftKingsFanDuelCaesarsbet365
Martinez-142-144-145-150
Aldo+120+122+122+125

Martinez will defend his six-fight win streak against Aldo this Saturday. Aldo, known as “Junior,” is one of the older fighters at 37 years old and is listed at +125 on bet365 as the underdog. This suggests a 44.44% chance of winning and offers a $12.50 profit on a $10 bet.

Anthony Smith (37-19) vs. Vitor Petrino (11-0)

FighterDraftKingsFanDuelCaesarsbet365
Petrino-470-490-500-550
Smith+360+380+360+400

Vitor Petrino is undefeated in all 11 of his professional fights, with four consecutive wins since joining the UFC. His odds at DraftKings predict a similar outcome on Saturday, with a -470 line that would only yield a $2.13 profit on a $10 bet, indicating an 82.46% chance of winning.

Michel Pereira (30-11) vs. Ihor Potieria (21-5)

FighterDraftKingsFanDuelCaesarsbet365
Pereira-600-600-600-600
Potieria+440+450+430+450

Pereira is another fighter who is expected to have an advantage fighting at home, although he may not necessarily need the support of the home crowd. Pereira has maintained an undefeated record since 2000, securing wins through decisions, submissions, and knockouts. With the shortest odds at -600 among our top sportsbooks, a $10 bet on Pereira would only yield a profit of $1.67, reflecting an 85.71% chance of winning.

Paul Craig (17-7-1) vs. Caio Borralho (15-1)

FighterDraftKingsFanDuelCaesarsbet365
Borralho-600-600-650-600
Craig+440+450+460+450

The main card kicks off with a challenging match for Scottish fighter Craig, who has faced defeat in three of his last four fights. Borralho, with only one loss on his record from 2015 in the Bradar Fight promotion, is the favorite with odds of -600 at bet365. This gives him an 85.71% chance of winning and a potential profit of $1.67 on a $10 bet.

FighterDraftKingsFanDuelCaesarsbet365
Brito-185-180-190-170
Shore+154+152+160+140

Although Shore has only one loss in his professional career, he is seen as a slight underdog against Brito for their fight on Saturday. Brito, also known as “Tubarao,” is a versatile fighter who has achieved both KO/TKO and submission victories in his last four fights, all within the first two rounds. With a -170 line at bet365, Brito has a 62.96% chance of winning and could earn $15.88 on a $10 bet if he emerges victorious.

Karolina Kowalkiewicz (16-7) vs. Iasmin Lucindo (15-5)

FighterDraftKingsFanDuelCaesarsbet365
Lucindo-395-420-420-400
Kowalkiewicz+310+330+320+300

Lucindo, 16 years younger than her competitor, has a two-inch reach advantage. With a -395 line at DraftKings, she stands out in a market where she is lined at -400 or shorter on other top sports betting sites. She has a 79.8% win probability and would profit an even $2.53 on a $10 bet.

Elves Brener (16-4) vs. Myktybek Orolbai (12-1-1)

FighterDraftKingsFanDuelCaesarsbet365
Orolbai-245-260-260-250

Brener enters this fight with a five-fight winning streak, with three wins at the UFC level. Orolbai also has a seven-fight winning streak, but only one win in the UFC. The Kyrgyzstan fighter has only gone to a decision once since 2020 and is favored at -245 on DraftKings.

UFC 301 odds – Early prelims

Joaquim Silva (13-5) vs. Drakkar Klose (14-2-1)

FighterDraftKingsFanDuelCaesarsbet365
Klose-205-198-195-188
Silva+170+166+165+162

Silva has had a tough time in his recent fights, only managing to secure two victories in his last five bouts. Despite being on home turf in Brazil, he is considered the underdog. The best odds for Silva can be found at DraftKings, with a line of +170. A $10 bet on Silva could potentially profit $17, but his implied win percentage is only 37.04%.

Mauricio Ruffy (9-1) vs. Jamie Mullarkey (17-7)

FighterDraftKingsFanDuelCaesarsbet365
Ruffy-218-225-235-225
Mullarkey+180+188+195+187

Mullarkey had a busy year in 2023, with a record of 2-2 including two unanimous decision wins and two KO/TKO losses. Despite his previous fights, this will be his first time in the Octagon in 2024, and the oddsmakers are not showing much confidence in him. Ruffy’s best odds are -218 at DraftKings, which means a $10 bet would bring a profit of $4.59 and implies a win probability of 68.55%.

Dione Barbosa (6-2) vs. Ernesta Kareckaite (5-0-1)

FighterDraftKingsFanDuelCaesarsbet365
Barbosa-238-250-250-250
Kareckaite+195+205+205+200

Barbosa, also known as “The Witch”, will be making her UFC debut after last competing in DWCS in September. The 31-year-old Brazilian fighter is considered a strong favorite against the much younger Kareckaite. With a -238 line at DraftKings, Barbosa has implied win odds of 70.41% and would pay $14.20 on a $10 wager, resulting in a profit of $4.20.

Ismael Bonfim (19-4) vs. Vinc Pichel (14-3)

FighterDraftKingsFanDuelCaesarsbet365
Bonfim-550-560-550-550
Pichel+410+420+400+400

Pichel, the lone fighter over 40 on the card, faces a significant age gap of 13 years against his 28-year-old opponent, Bonfim. Bonfim is the first of many fighters of the night with odds set at -550 or higher, meaning a $10 bet on him would only profit $1.82 with an implied win probability of 84.62%.

Alessandro Costa (13-4) vs. Kevin Borjas (9-2)

FighterDraftKingsFanDuelCaesarsbet365
Costa-122-126-120-125

How to read UFC betting odds

It is crucial to understand UFC betting odds in order to make informed wagers. Let’s explore this concept further 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).

Let’s now examine a real-life UFC betting situation:

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

Fighter A (+200) would earn a $200 profit from a $100 bet, resulting in a total payout of $300. Fighter B (-180) requires a $180 bet to earn a $100 profit, resulting in a total payout of $280.

Knowing these odds will assist you in assessing the possible payout and implied likelihood of victory for each fighter in a UFC match. Positive odds suggest the fighter is an underdog, while negative odds indicate they are the favorite.
