MMA Betting Preview: Week of October 12, 2026
Ten MMA bouts are on the slate for the week of October 12, and the MMA odds are sending a clear message: this card is top-heavy with heavy favorites. From a -455 steamroller on Tuesday to a pair of sub-200 chalk on Saturday, only one fight all week sits close enough to even money to qualify as a genuine coin-flip. That fight, Ilias Bulaid vs. Erick Visconde, is the rare spot where the books genuinely don't know. The rest of the card rewards careful risk-reward analysis, and if you're hunting underdog value, Saturday's main slate deserves a close look.
Tuesday, October 13: MMA Odds Preview, Three Fights and One Monster Favorite
Tuesday opens with five bouts, three at 4:00 PM PDT and two in the early evening.
Smilla Sundell vs. Aline Pereira (-455 to -400)
Sundell is the biggest favorite on the entire week's slate. Novig and ProphetX both post her at -455, implying roughly an 82% win probability. The softest line is Kalshi and BetOnline at -400, still an 80% implied probability. Pereira is available at +310 to +376 depending on where you shop, with Polymarket offering the most generous number at +376.
The market has essentially closed the book on competitiveness here. At these prices, the juice on Sundell is brutal. The only real case for Pereira is if you believe the market has overcorrected on the matchup.
Douglas da Lapa vs. Davi Cabral (-233 to -185)
Da Lapa is a solid favorite at a consensus around -200 to -230. ProphetX sits at the sharp end with -233, implying about 70%. Kalshi posts the softest line at -185, implying closer to 65%. That gap is notable: if you're playing da Lapa, Kalshi is the clear best price. Cabral ranges from +174 to +194 across books as a legitimate live underdog.
The under 1.5 rounds is also drawing juice, with Novig at -179 and BetOnline at -154, suggesting the books lean toward a finish.
Jason Asher vs. Greg Foster (-222 to -192)
Asher draws a near-identical profile to da Lapa: a solid but not crushing favorite. The line ranges from -192 at Kalshi to -222 at ProphetX, with implied probabilities running from roughly 66% to 69%. Foster sits at +168 to +203 as the underdog, with Polymarket posting the most generous number at +203.
Luis Francischinelli vs. Will Rentz (-278 to -256)
Starting around 5:05 PM PDT, Francischinelli is a more emphatic favorite at -256 to -278, with implied probabilities in the 72-74% range. Rentz gets a look at +205 to +233. The totals market is equally lopsided: Novig has the under 1.5 rounds at -294 and BetOnline sits at -250, signaling a strong expectation of a finish inside the first round and a half.
Ilias Bulaid vs. Erick Visconde: The Closest Betting Line of the Week
Closing out Tuesday around 5:55 PM PDT, this is the fight the market is most uncertain about. Bulaid opens as a narrow favorite at just -130 at Novig and BetOnline, with Kalshi posting the tightest line at -127. Visconde is available at +106 to +127, with ProphetX posting him at +106, making this almost a true even-money play on the de-vigged number.
When a line is this compressed, the market sees approximately equal chances on both sides. A -130/+110 structure at BetOnline carries meaningful vig for how close this is, so line shopping genuinely matters. Visconde backers should head to Polymarket's +127. If you prefer Bulaid, Kalshi's -127 saves real juice compared to the -135 at ProphetX. Use the Odds Converter to run the exact implied probabilities side by side, because in a fight this tight, a few points of vig can shift your expected value meaningfully.
Saturday, October 17: Betting Odds for the Main Card
Saturday brings five bouts all starting at 2:00 PM PDT, ranging from a clear-cut heavy favorite to a handful of solid chalk and one intriguing mid-range underdog situation.
Erin Blanchfield vs. Jasmine Jasudavicius (-333 to -278)
Blanchfield is the biggest name on Saturday's card. She opens as a substantial favorite from -278 at BetMGM to -333 at BetOnline, with ProphetX at -312. The most bettor-friendly price on Blanchfield is BetMGM at -278, implying roughly 73.5%. Jasudavicius ranges from +225 at BetRivers and BetMGM up to +267 at BetOnline. If you like her as a longshot, BetOnline's +267 is nearly four probability points better than +225, and that difference compounds over time.
The totals market is decisive: BetOnline has the over 2.5 rounds at -400 and Bovada goes even harder at -455, both pointing toward a dominant performance that probably doesn't need all five rounds.
Mandel Nallo vs. Nate Landwehr (-294 to -244)
Nallo opens as a clear but not overwhelming favorite. The line ranges from -244 at Kalshi (implying about 71%) to -294 at Novig and ProphetX (implying about 75%). Landwehr gets +215 to +233 as the underdog, with DraftKings at +230 and Polymarket at +233.
The totals market strongly favors an early finish. BetUS and BetOnline both have the under 1.5 rounds at -238, and Bovada is sharper at -263. That kind of under price suggests the books expect this one to end quickly if Nallo performs to his ceiling.
Melissa Croden vs. Chelsea Chandler (-278 to -244)
Croden is the clear favorite, with lines clustered at -278 across BetRivers, Novig, and ProphetX, all implying about 73.5%. The softest numbers are Polymarket at -244 and Kalshi at -256, so those are the books to use if you want Croden. Chandler ranges from +205 at ProphetX up to +225 at BetOnline.
The over/under sits at 2.5 rounds with books leaning toward the over at -161 to -189. BetOnline offers the most value on the under at +140 if you think this one ends early.
Kyle Daukaus vs. Marc-Andre Barriault (-244 to -204)
Daukaus is the favorite, ranging from -204 at Kalshi to -244 at BetUS and ProphetX, with implied probabilities running from roughly 67% to 71%. Kalshi's -204 is meaningfully softer than the market consensus around -230, so Daukaus backers should head straight there.
Barriault as the underdog is where value-hunting gets interesting. He's available from +180 at BetRivers up to +210 at BetOnline, a legitimate spread for a fighter with a consensus around +185. The totals sit at 2.5 rounds with the over at +117 to +130, making duration close to a coin flip, with most books leaning slightly toward the under at -149 to -179.
Louis Jourdain vs. Timothy Cuamba (-213 to -179)
Jourdain closes out the Saturday card as a moderate favorite. The range is relatively tight, from -179 at Polymarket to -213 at BetUS and BetOnline, with implied probabilities clustered between 64% and 68%. Cuamba sits at +155 to +178 as the underdog, with BetRivers at +155 and BetUS posting the most generous number at +178.
The totals lean over on the 2.5-round mark. Novig is at -154 for the over and DraftKings offers the tightest number at -141. If you think this fight goes deep into round three or the distance, DraftKings gives you the least painful entry.
