UFC Fight Night: Allen vs Costa Odds, Picks & Where to Stream Live
The featherweight main event at Ultimate Fighting Championship UFC Fight Night: Allen vs Costa on May 16, 2026, feels like a classic crossroads fight inside the UFC Apex. Former title contender Arnold Allen enters trying to remind everyone he still belongs among the division’s elite after a brutal recent schedule, while surging Brazilian finisher Melquizael Costa looks ready to crash the top 10 with another statement performance.
Costa has become one of the hottest names at 145 pounds, riding a six-fight win streak capped by a vicious TKO over Dan Ige — the first stoppage loss of Ige’s career. But Allen has been in the deep waters against monsters like Max Holloway, Movsar Evloev, and Jean Silva, and that level of experience matters massively in a five-round fight.

Expert Picks: Arnold Allen vs Melquizael Costa
🥇 Best Bet: Arnold Allen by Decision
Arnold Allen has gone to decision in five of his last six UFC fights, including battles with elite featherweights like Max Holloway and Movsar Evloev. Costa’s aggressive style creates danger early, but Allen’s durability, clean counter-striking, and five-round experience strongly favor a late technical takeover on the scorecards.

Pick 2: Over 3.5 Rounds
This matchup profiles as a long tactical main event rather than an early firefight. Allen has never been finished in 24 professional fights, while Costa’s pace historically slows once opponents survive the opening rounds. Both fighters are durable southpaws with solid defensive awareness, making extended rounds highly realistic for bettors.
Pick 3: Fight Goes the Distance
Allen’s recent fights consistently reach the judges because of his disciplined striking and measured pace management. Costa owns finishing upside, but stepping into his first UFC main event against a durable veteran is a different challenge entirely. If Allen controls range and mixes occasional wrestling entries, this likely reaches Round 5.
Pick 4: Allen Live Betting After Round 1
Costa tends to explode early with pressure and volume, averaging 4.38 significant strikes landed per minute while hunting fast momentum swings. Allen often starts slower before adjusting technically as fights progress. Bettors could find strong live value if Costa wins the opening round but begins slowing entering the middle rounds.
Key Matchup Angles
- Allen has never finished in 24 professional fights
- Costa enters on a six-fight winning streak

Final Prediction
This fight feels dangerous for Allen early, before he gradually swings in his direction. Melquizael Costa absolutely has real upset potential with his pressure, finishing instincts, and aggressive kicking game. If Allen gets dragged into chaotic exchanges too often early, things could get uncomfortable quickly.
But stylistically, Arnold Allen still feels like the more reliable side over five rounds. His durability, defensive structure, wrestling control, and elite-level experience should allow him to survive the dangerous moments and steadily bank rounds late. Expect Costa to start hot before Allen slowly takes over the fight technically.
