UFC Fight Night: Allen vs. Costa - Full Betting Odds and Predictions

UFC Fight Night: Allen vs. Costa Preview

UFC Fight Night returns on May 16, 2026, featuring a featherweight main event that promises high-level technical striking and grappling. Arnold 'Almighty' Allen looks to defend his ranking against the surging Melquizael Costa in a clash of southpaws.

Arnold Allen vs. Melquizael Costa (Featherweight)

Arnold Allen enters this bout with a significant experience advantage and a flawless 100% takedown accuracy according to recent data. While Costa is a versatile threat with 11 finishes to his name, Allen's superior strength and ability to control the pace of the fight should be the deciding factor. Expect Allen to neutralize Costa's striking with clinch work and timely takedowns.

• Prediction: Arnold Allen via Decision
• Confidence: High

Daniel Santos vs. Dooho Choi (Featherweight)

This is a classic striker-versus-striker matchup where Dooho Choi brings a massive 65.1% strike accuracy. Santos is a resilient fighter, but Choi's precision and 70-inch reach will likely find the target more frequently in the early exchanges. If Choi can maintain his gas tank, he should find the finish.

• Prediction: Dooho Choi via KO/TKO
• Confidence: Low

Jacqueline Cavalcanti vs. Ketlen Vieira (Women's Bantamweight)

Ketlen Vieira is a seasoned veteran of the division with a resume filled with top-tier talent. Cavalcanti is undefeated in the Octagon but has relied heavily on the judges, with all five of her wins coming by decision. Vieira's 40% takedown accuracy and physical strength should allow her to dictate where this fight takes place.

• Prediction: Ketlen Vieira via Decision
• Confidence: Medium

Andre Petroski vs. Cody Brundage (Middleweight)

Both men are known for their wrestling, but Andre Petroski holds a superior takedown accuracy of 54.3%. Brundage has been inconsistent in recent outings, often struggling when he cannot secure the early finish. Petroski's 50% finish rate and better grappling efficiency give him the edge in a grinding affair.

• Prediction: Andre Petroski via Submission
• Confidence: Medium

Khaos Williams vs. Nikolay Veretennikov (Welterweight)

Khaos Williams possesses a massive 77-inch reach that he uses to deliver fight-ending power. Veretennikov is a technical striker with 10 KO wins, but his 22.2% takedown accuracy suggests he will be forced to stand and trade with the 'Khaos.' This fight likely ends in a highlight-reel moment.

• Prediction: Khaos Williams via KO/TKO
• Confidence: Medium

Ivan Erslan vs. Tuco Tokkos (Light Heavyweight)

Ivan Erslan brings a much deeper professional record and a higher strike accuracy compared to the relatively inexperienced Tokkos. Tokkos has shown vulnerability in his previous UFC outings, and Erslan's power (5 KO wins) should be enough to overwhelm him early in the first or second round.

• Prediction: Ivan Erslan via KO/TKO
• Confidence: Medium

Juan Diaz vs. Malcolm Wellmaker (Bantamweight)

Malcolm Wellmaker enters this bout as a heavy favorite against the debuting Juan Diaz. Wellmaker's 10-1 record and switch-hitting style provide a level of complexity that is difficult for any debutant to handle. Unless Diaz has a hidden grappling pedigree, Wellmaker's 54.8% strike accuracy will pick him apart.

• Prediction: Malcolm Wellmaker via KO/TKO
• Confidence: High

Christian Edwards vs. Modestas Bukauskas (Light Heavyweight)

Modestas Bukauskas is a true UFC veteran with 19 wins and a perfect 100% takedown accuracy. Christian Edwards is entering the deep end for his debut, and it is hard to see a path to victory against Bukauskas's switch-stance pressure and 78-inch reach. Experience will be the deciding factor here.

• Prediction: Modestas Bukauskas via KO/TKO
• Confidence: High

Bernardo Sopaj vs. Timmy Cuamba (Bantamweight)

Bernardo Sopaj boasts an impressive 71.4% takedown accuracy, which will be his primary weapon against the taller Cuamba. Cuamba has more reach, but his 31.6% takedown defense suggests he will spend a significant portion of this fight on his back. Sopaj's control should earn him the cards.

• Prediction: Bernardo Sopaj via Decision
• Confidence: Low

Artur Minev vs. Tommy Gantt (Lightweight)

This is a matchup between two regional newcomers with no statistical history in the UFC. In such instances, we often look at training camps and youth; however, with both fighters at 0-0-0, the bout remains a total enigma. We give the slight edge to Minev based on rumored wrestling credentials.

• Prediction: Artur Minev via Decision
• Confidence: Low

Summary

UFC Fight Night: Allen vs. Costa is a card defined by the clash between seasoned veterans and fresh talent. While the main event features the technical excellence of Arnold Allen, the undercard provides several opportunities for heavy hitters like Khaos Williams and Malcolm Wellmaker to secure emphatic victories.
