MMA Betting Preview: Week of August 17, 2026
Eighteen fights across four days make this one of the fuller MMA betting slates of the summer. The odds range from near-coinflip matchups to some of the most lopsided lines in combat sports. Whether you are hunting value on a live underdog or deciding if a -1000 chalk is worth touching, here is the full breakdown by day.
Tuesday, August 18 MMA Odds Breakdown
The Heavy Chalk
Tuesday opens with three fights where the books have taken a clear position. Trent Miller vs. Douglas Rodrigues is the most emphatic: Miller is installed at -333 (implied probability: 77%), meaning you risk $333 to win $100. Rodrigues at +267 carries a 27% implied win probability. Fighters in that range do win, but the market is not encouraging you here.
Mahamed Aly vs. Alik Lorenz follows a similar structure. Aly is priced at -286 (74%), Lorenz at +234 (30%). A 44-point gap in implied probability is meaningful. Unless you have a strong read on a stylistic edge the market is missing, this one is fairly one-sided.
Fights Worth Watching
Taner Trembley vs. Roman Puga is Tuesday's most competitive bout. Trembley opens at -169 (63%) and Puga at +149 (40%). Neither fighter is a true underdog by MMA standards, and tight lines like this are exactly where shopping for the best number pays off. Even a few points of difference in the moneyline can shift your long-term edge.
Kaik Brito vs. Namo Fazil rounds out Tuesday with Fazil as the slight favorite at -147 (60%) against Brito at +127 (44%). The implied probabilities nearly cancel each other out after juice. If you have a lean here, the line is not punishing you heavily for either side.
Wednesday, August 19
One fight on the card: Cristian Pérez vs. Logan Paxton. Pérez is the clear favorite at -227 (69%), with Paxton at +189 (35%). Well past pick-em territory. Paxton's implied probability is low enough that you would need strong conviction to go there.
Saturday, August 22 MMA Odds Breakdown
The Extreme Chalk Fights
Saturday has two fights that are essentially no-contests in the eyes of the market. Márcio Barbosa vs. Ryan Kuse has Barbosa installed at -909 (90% implied probability), with Kuse at +613 (14%). Anthony Wint vs. Terrance Chatman is even steeper: Wint sits at -1000 (91%). These lines offer almost no value on the favorite side and carry enormous risk on the underdog. Proceed with caution.
Shanelle Dyer vs. Elise Reed falls into a similar bucket. Dyer is priced at -588 (85%), with Reed at +425 (19%). You are risking nearly six dollars to win one. The implied probability is high, but so is the cost of being wrong.
The Pick-Em of the Week
The most interesting fight on Saturday, and arguably the week, is Chris Padilla vs. Nasrat Haqparast. Padilla is priced at -105 and Haqparast at -115. That is as close to a true pick-em as you will find in MMA. When both fighters are priced this close to even money, the market has no strong opinion. Your own analysis on styles, recent form, or physical matchup carries real weight here. A -105 or -115 price is not a heavy tax on a well-reasoned view. Check live odds comparisons on the UFC page before locking anything in, because a half-point difference matters at these prices.
Shamil Gaziev vs. Kennedy Nzechukwu is also worth attention. Nzechukwu sits at -135 while Gaziev is at +110, positive moneyline territory on a fighter the books only slightly disfavor. The spread is narrow enough to make either side defensible.
Jamall Emmers vs. Lerryan Douglas has Emmers at -400 (80%). A heavy price, but the 1.5-round total suggests the books expect a quick finish. Jackson McVey vs. Wes Schultz has McVey at -185 (65%), a moderate favorite in what looks like a standard prelim.
Sunday, August 23 MMA Odds Breakdown
The Headliners
Gregory Rodrigues vs. Anthony Hernandez closes the week and carries the highest total on the board at O/U 3.5 rounds. Rodrigues is favored at -179 (64%) with Hernandez at +145 (41%). The elevated total signals the books expect this one to go late. If you are interested in fight duration markets, this is the matchup to study.
Reinier de Ridder vs. Roman Dolidze has de Ridder at -370 (79%), one of Sunday's stronger favorites. Dolidze at +300 carries a 25% implied probability, a long-shot price but not as extreme as Saturday's top chalk.
Vitor Petrino vs. Sergey Spivak offers a solid mid-card line with Petrino at -169 (63%) and Spivak at +149 (40%). The spread mirrors Tuesday's Trembley-Puga line: enough of a market lean to identify a side without completely closing the door on the underdog.
Jeisla Chaves vs. Carli Judice has Chaves at -526 (84%) and Judice at +380. The 2.5-round total adds context: the books do not expect an immediate finish, which may be relevant for method-of-victory markets.
Marquel Mederos vs. Mason Jones wraps the week with Mederos at -278 (74%) against Jones at +220 (31%). If you are building any multi-fight parlays, use the Parlay Calculator to see exactly how implied probability compounds across legs before you commit.
Key Takeaways for the Week
This slate covers every betting style. The Padilla-Haqparast pick-em is where the market is most open to being beaten. The extreme chalk fights on Saturday offer almost no return on the favorite side. The moderate favorites throughout Tuesday and Sunday give you spots where a well-reasoned underdog play does not require a massive edge to be worthwhile. Shop your lines, know your probabilities, and do not chase value just because a number looks big.
