Yuneisy Duben vs. Jeisla Chaves UFC Odds

Early pricing has made “A Braba” Chaves the clear favorite. One market listed Chaves at -395 and Duben at +310, while another showed Chaves at -430 and Duben at +300, which signals a stronger favorite price as the week of the fight got closer. In Situs 888 format, that means a bettor would need to risk $395 to win $100 on Chaves at -395, or win $310 on a $100 wager on Duben at +310.

The split between books is small, but it tells the same story, Chaves has been backed by the market, while Venezuela’s Duben has stayed in a live underdog range. No major line movement recorded yet on the method markets, suggesting the biggest action has been on the moneyline rather than a sharp swing in finish props. These are Chaves by decision at +140, by knockout at +205, and by submission at +400, while Duben by decision sat at +600 and Duben by knockout at +800. That setup suggests the market sees Chaves as the likelier winner, with decision and knockout both in play depending on how much Duben can absorb early.

The Brazilian Chaves brings the cleaner unbeaten record and a strong finishing note into her UFC debut with a 50% knockout win rate. Duben has more UFC-level experience plus an impressive 83% knockout win rate. She made an impression on fans with an overhand KO of Shannon Clark in the first round of her Contender Series bout. However, markets have cooled on her as she is coming off a knockout loss to Carli Judice in her most recent outing.

The market has settled on Chaves as the side with the higher ceiling and safer path, but Duben’s power gives her a chance if she can keep the fight upright and force Chaves to work defensively. Chaves looks like the more rounded pick on paper, with better accuracy, better defense, and the cleaner unbeaten record. The most likely outcome is Chaves to win, with decision and knockout both live depending on whether Duben can slow the pace and stop the momentum early.
